Dr. de Planque reported that she attended a fact-finding with Consultants Wardell and Dr. Cass on May 1-2, 2001, which included their attendance as observers at a meeting of PG&E's Nuclear Safety Oversight Committee(NSOC). Mr. Clark reported that he and Consultant Wardell attended a fact-finding at DCPP during March 2001. b) Documents provided to the Committee: Lists of the documents provided to the Committee since its last public meeting in February 2001 were included as a part of the public agenda packet for this meeting. A short break followed. VI STAFF-CONSULTANT REPORTS Consultant Wardell reviewed topics from the March 14-16, 2001 fact-finding he attended with Member Mr. Clark. These included revision of the DCISC-DCPP Performance Indicators, with reference to eliminating possible duplication between the DCISC-selected indicators and the performance indicators developed by and reported to the Nuclear Regulatory Commission(NRC)and the Institute for Nuclear Power to Operations(INPO),and a suggestion that a section be added and the DCISC Annual Report concerning performance indicators the DCISC representatives met with the current Assistant NRC Resident Inspector for DCPP. Topics reviewed included: the modeling techniques used in NRC reports on refueling outage risk and plant-specific shutdown risk analysis; the NRC Maintenance Rule, enhancements to on-line maintenance, and the impact of the California energy supply situation on B. 9-3
maintenance; enhancements to the Corrective Action Program(CAP)based upon the Nuclear Energy Institute (NEI) CAP indicators, root-cause benchmarking study and INPO review, and analysis and the CAP interface with human resources performance improvement programs; winter storm operational experience and power generation curtailment; environmental flow performance; Reactor Coolant System(RCS)hot leg time PG&E officers measurement data development; the amount of currently have available for review of DCPP operational activities given the utility's bankruptcy situation and the management's other commitments; a system review of long-term plans; two Auxiliary Saltwater System(ASW) and ASW 2000, both of Licensee Event Reports(LERs)instituted during the which involved relays. The DCISC representatives toured the Intake Structure and portions of the main Plant and representatives the Control Room and discussed with PG&E Programs; Configuration Management and Equipment Qualification to human regulatory compliance issues and LERs initiated due and error during Unit l's(U-l)tenth refueling outage(lRl0) implementation of any support programs for the DCPP Performance Plans. Consultant Wardell observed a Shift Technical Advisor training class, attended a management discussion concerning the "Brown Bag" direct management weekly employee informational exchange program conducted during lunch hour, and he attended a table-top emergency exercise exercise at the Technical Support Center(TSC) and an scenario at the Emergency Offsite Facility(EOF). fact Mr. Wardell then reviewed the topics from the May and finding he attended with Committee Member Dr. de Planque their attendance at a meeting of NSOC. Topics reviewed Protection included recent changes proposed in the Radiation roles and (RP) organization to increase accountability, define the enhance the process bases and to better align RP with and the RP special Operations and Maintenance organizations for RP preparations for 2R10 and new innovations proposed Radiation Control signage. DCISC representatives toured the used in Area(RCA)and reviewed with PG&E the analytical tools DCPP, in the Emergency Preparedness Program and efforts by improve communication of conjunction with the NRC, to They received updates radiological information to the public. on the objectives of the Strategic Teaming and Resource results of Sharing(STARS)joint-utility cooperative program and The DCISC the Cultural Assessment performed by Synergy, Inc. a meeting of NSOC which representatives attended as observers included a report on the activities of the NSOC Corrective Action Oversight and Assessment Sub-Committee, established to review Nuclear Quality Services(NQS)audits, self-assessments and the CAP. B.9-4
Consultant Booker reported on a fact-finding attended with Member Dr. Rossin which was held at DCPP on April 18-19, 2001. Topics reviewed included: a discussion with DCPP Communications Director Jeff Lewis concerning communication with the public about the new proposed spent fuel dry storage facility to be located at DCPP; results of the Synergy Cultural Survey and a preliminary review of the recent INPO evaluation; a presentation from a training instructor from the Chemistry Department concerning the training program accreditation efforts; an update on the self-assessment process; the status of the bankruptcy matter; plans for on site dry cask storage of spent fuel; an update on the Probabilistic Risk Assessment(PRA) and the Aging Management Programs; the Quality Assurance(QA)audit of the Security Department; an overview of the Component Cooling Water System(CCW); an informal discussion with the RP Program Manager; and a presentation from NQS on the status of improvements they have made since the last biennial audit in NQS self-assessment and plans for utilizing peers from other plants to help with the next biennial audit. Dr. Cass reported on a fact-finding meeting she attended with Member Dr. de Planque on June 19, 2001. Topics included an update on human performance, which indicated that there has been a decrease in the human error rate at DCPP since the last refueling outage. Dr. Cass reported on an inquiry received by the Committee's Administrative Office from an operator at another commercial nuclear power generating facility which concerned PG&E's policy and use of "power naps" during night operations at DCPP and her inquiries to PG&E on this subject during the fact-finding. She briefly discussed the PG&E policy for enhancing stress management skills by permitting two 30-minute breaks in each 12-hour shift, during which employees are allowed to exercise, shower, take a nutrition break or to nap or otherwise relax to enhance their alertness. PG&E was requested to reply to the inquiry received on behalf of the Committee and to provide the DCISC with a copy of their reply. Dr. Cass provided examples and an update to the information she received during a December 13, 2000 fact finding, reviewing a multi-level, behavioral, observation based safety enhancement program, termed "BOBsCATz" (Behavior Observation-Based Safety Cuts Accidents To Zero), for DCPP Maintenance personnel to track incidents, evaluate and identify risks, communicate and correct or eliminate barriers to personnel safety and unsafe work practices. She reported her observation that communication fostered by the Program, which is built on mutual trust and understanding of plant craft specific issues, has created a shift in culture for the B. 9-5
workers involved and resulted in an increase in the availability of equipment and material necessary to work safely. She noted that improvement has been reported in terms of work control areas, housekeeping, material storage, environment, hoses and leads, barricading and posting job sites. Dr. Cass observed that these enhancements to a safe work environment should also have a beneficial effect on that significant portion of the DCPP workforce, which is impacted by age-related issues. Dr. de Planque observed that the Program is being used to predict what areas are at risk and then direct attention and resources to those areas. Dr. Cass, in response to a question from Dr. Rossin, reported that the BOBCATZ Program's steering committee are all volunteers and that the Program appears to have the support of the bargaining unit and has fostered a sense of empowerment and control and improved morale within the craft personnel. Dr. de Planque remarked that the group she and Dr. Cass interviewed appeared to be incredibly motivated and showed very strong ownership of the Program and she observed that she has rarely seen the level of enthusiasm for a program, which was demonstrated by this group. Dr. Cass reported that there is a plan to expand the Program to the Operations, Security and RP organizations in the future. Dr. Cass reported on a general, overall work process review presented to the Committee's representatives to outline and compare the old function-based manner of managing work to the new process-based method of task management and to impact and improve safety. She reported that the transition to the process-based work management model is still underway and that the Committee has committed to follow PG&E's progress during future fact-finding. The Chair requested that he and Dr. Rossin be provided with a copy of the comprehensive design chart developed by PG&E for use in implementing the process based model. Dr. Cass reported on her review of the Employee Assistance Program(EAP)which was recently relocated to the Administration Building, outside the protected area, and she observed this may result in an increase in privacy for personnel availing themselves of the EAP. She stated that the EAP works closely with the Fitness-For-Duty Program to identify and address, or refer if necessary, employee-related alcohol, drug, psychological or family issues. Supervisors receive monthly training in behavioral observation and she noted that the majority of referrals to EAP are by way of self-referral. She observed that the EAP appears to have gradually gained a significant level of trust among DCPP employees and that the EAP newsletter appears to be an effective tool for focusing employee attention on EAP issues B. 9-6
and available services. Issues arising from the aging of the DCPP workforce, the recent utility bankruptcy and the energy supply situation and its impact on PG&E's business have been addressed to varying degrees by the EAP. Members and Consultants posed questions for Dr. Cass concerning need for an off-site location for EAP access by family members, reporting requirements should a situation have the potential to constitute an imminent threat to nuclear safety and issues involving anonymity for participants in EAP or any associated 12-step programs. In concluding her report, Dr. Cass remarked that a representative of the DCPP Medical Center reviewed issues concerning operator fitness and the aging of the DCPP workforce and the PG&E representative confirmed that annual testing is done to identify potential problems. Security officers were offered, and some received, a $1,200 bonus for passing a physical fitness test. The Medical Center and the NRC conduct reviews of licensed operator's medical files and an absence from work due to a medical condition of over three days requires medical consultation prior to returning to work. Mr. Clark commented on favorable industry-wide trends concerning employee drug or alcohol use, and noted that a recent NRC testing conducted at unidentified nuclear facilities resulting in 1 positive from a random test of 505 employees. Mr. Clark requested that the DCISC obtain and conduct a confidential review of current statistics from DCPP. Legal Counsel Wellington reminded the members that the California Fair Political Practices Commission requires annual statements concerning conflict of interest from each member of the Committee and he provided copies of the current Form 700 used for this purpose. He distributed updated Committee rosters containing addresses, email and telephone contact information. The Committee's newly revised general informational pamphlet was also distributed to Members and Consultants and available to those present in the audience. Mr. Wellington noted that the Minutes of the February meeting were provided to PG&E for their comment, if any, and that the transcript of the public meetings would continue to be filed with the NRC Public Document Room at the R.E. Kennedy Library at California Polytechnic University at San Luis Obispo and are available in print or electronic format to anyone requesting a copy. He observed that the DCISC is receiving an increasing number of contacts initiated through its website at www.dcisc.org and he stated that members of the public communicating with the DCISC to request information from or concerning PG&E should be contacted, and their agreement and understanding regarding confidentiality obtained, prior to the B. 9-7
Committee providing information about the request to PG&E. The Committee requested an update during its next public made meeting in October 2001,concerning the number of contacts on the DCISC website. Mr. Wellington reported that he is to PG&E's continuing to monitor the situation with reference for bankruptcy protection under Chapter 11 of the filing Federal Bankruptcy Code. He reported that PG&E's Application concerning the rate freeze which was befcre a California Public Utilities Commission(CPUC)Administrative Law Judge and taken which if granted would terminate the Committee, has been Mr. off the CPUC's calendar, however, it remains pending. Clark remarked that he had spoken recently with PG&E Senior that Vice President Rueger and reported that Mr. Rueger stated PG&E is not, at the present time, actively seeking the elimination of the Committee and that the nomination and abeyance, appointment process for DCISC members, currently in would resume. Mr. Clark suggested that the Committee Members may wish of to consider developing a fresh approach to consideration the impact of human performance and behavioral issues on safety at DCPP, possibly using an approach akin to past as the Committee dedicated studies of particular issues such and Control System cracking experienced by the Chemical Volume (CVCS) and the DCPP Seismic and QA Programs. VII COMMITTEE FACT-FINDING REPORTS Discussion concerning fact-finding reports was the deferred to the afternoon session on Wednesday during Members concluding remarks. VIII CORRESPONDENCE Copies of correspondence to and from the Independent Safety Committee were included in the agenda packets provided to those present and placed on file in the NRC Public Document Room of the R.E. Kennedy Library. IX PUBLIC COMMENTS AND COMMUNICATIONS Mr. Clark invited any member of the public present time. who wished to address the Committee to do so at this There was no response to this invitation. X ADJOURNMENT The morning meeting of the Diablo Canyon Independent P.M. Safety Committee was adjourned by the Chair at 12:35 B. 9-8
XI RECONVENE FOR AFTERNOON SESSION The Chair convened the DCISC for its afternoon meeting at 2:00 P.M. XII COMMITTEE MEMBER COMMENTS There were no comments by Members at this time. The Chair requested PG&E Vice President Larry Womack to introduce the first of the technical presentations requested by the Committee. XIII INFOR14ATION ITEMS BEFORE THE COMMITTEE Mr. Womack introduced DCPP Director of Outage Planning-Outage Management Jeff Hays to make the first technical presentation to the Committee Results of the Tenth Refueling Outage for Unit 2 (2Rl0). Mr. Hays began the presentation by briefly reviewing his professional background. He observed that 2R10 represents DCPP's most successful outage to date and he compared and discussed 2R10's goals, budgets, actual results achieved and the previous best performance for DCPP in several categories as follows: " Safety - goal was 0 disabling and 0 reportable injuries, actual performance was 0 disabling and 1 reportable injury which involved a laceration to the forehead of a maintenance worker when a drain plug he was removing from a charging pump sheared off. Previous best prior performance during an outage period for either Unit was 0 disabling and 4 reportable injuries. "* "As Low As Reasonably Achievable"(ALARA)Radiation Exposure goal was 109 person-rem, actual performance was 107.6 person-rem and best prior performance during an outage period for either Unit was 120.4 person-rem.
" Human Performance - goal was 0 significant events, actual performance was 1 significant event, which resulted in a start up of the emergency diesel generator(EDG)system when a feeder breaker was inadvertently left in test position because its position was not properly tagged to accurately indicate its status to Control Room personnel performing surveillance testing procedure(STP)M-13H. Best prior performance during an outage period for either Unit was 2 B.9-9
significant events. " Security - goal was <= 26 events, actual performance was 26 events and best prior performance during an outage period for either Unit was 24 events. "* Cost - goal was $29.2 million, budget was $30 million, actual cost was $30 million and lowest outage cost to date for either Unit has been $25.5 million. " Schedule - goal was 25 days and 19 hours, budget was 35 days, actual performance was 29 days and 11 hours. Generator core tightening inspection added 3 days and 16 hours to the baseline schedule. Best prior performance during an outage period for either Unit was 31 days and 18 hours. Members and consultants asked several questions during Mr. Hays discussion of the 2R10 outage achievements to which he and Vice President Womack responded. Mr. Hays reviewed and commented on the routine and recurring major items of work which are contributors to the scope of any DCPP outage and other major projects and emergent work which were addressed and identified during 2R10, these included: "* Refueling the Reactor. "* Critical Valve Maintenance. "* Steam Generator(SG)Maintenance and Inspection.
"* Turbine Generator Maintenance and Inspection. "* Diesel Generator Maintenance. "* Vital Bus-H Maintenance. "* Surveillance Testing.
Major projects included in the scope of 2R10 included:
"* Containment Recirculation Sump Screen Replacement. "* Reactor Coolant Pump Cable Replacement. "* Current Transformer De-Mount.
B. 9-10
0 Traveling Screen Motor Upgrading. "* 12kV Auxiliary Bus 2-1 Upgrading to Copper. "* Feedwater Piping Replacement. "* Vacuum DeGas System installation Significant emergent work which was identified and addressed during 2R10 included torque work on generator through bolts and building bolts and repairs to Control Rod Drive Mechanism(CRDM)H-10 canopy seal weld. Members and Consultants discussed with Mr. Hays and Mr. Womack the impact of the emergent work. It was suggested that a presentation be included during the scheduled fact-finding in July 2001 to further review the experience and the inspection results at DCPP and at other nuclear facilities with reference to CRDM cracking and leakage issues. In concluding his presentation, Mr. Hays identified pre outage planning, an increase in the number of outage preparation milestones, adherence and monitoring of outage scheduling, cost forecasting, daily tracking and increased control as areas identified for future improvement from DCPP's 2R10 experience. He confirmed that the next DCPP refueling outage is presently scheduled for May 5, 2002 for U-1. In response to a question from Mr. Clark, Mr. Hays observed that the number of clearance-related errors was reduced during 2R10 from that experienced during past outages. Vice President Womack then introduced DCPP Radiation Protection Manager Bob Hite for a presentation to the Committee. 2R10 Radiation Exposure Rate Results. Mr. Hite reviewed the major goals for 2R10 which included <109 person-rem cumulative personnel exposure, 0 high radiation area boundary violations, 0 Radiological Control Area(RCA) entries without electronic dosimetry and 0 disabling injuries. Mr. Hite reviewed for the Committee some of the major challenges for DCPP during 2R10 concerning radiation protection including source term concerns in the Reactor Coolant System(RCS)leading up to the outage, due to suspected fuel defects and an increase in noble gas, the shutdown chemistry process and RCS vacuum fill due to the very short transition from Mode 5 to Mode 4 operations. B.9-11
Mr. Hite confirmed that the 2R10 personnel dosage was 107.6 person-rem, which was the result of an excellent work shutdown chemistry process and he noted that the emergent to the was well handled and was not a significant contributor overall dose results. He noted that DCPP performance for U-1 of and U-2 is presently in the middle of the third quartile INPO-tracked 3-year rolling averages of plant performance statistics for personnel exposure during refueling outages. In response to a query from Dr. de Planque, Mr. Hite replied that it is unusual for an individual to receive 1 rem of exposure and that no DCPP personnel are allowed to go over 2 rem without prior approval by PG&E management. He reported that there were no high radiation area boundary violations during 2R10. The RCA posting program was significantly overhauled with the necessary information color coded and radiation protection control points for personnel were relocated during 2R10 to outside of Containment. There were in no RCA entries without functional electronic dosimetry place and new turnstiles connected to dosimetry readers were installed which helped facilitate meeting this goal. Mr. Hite reviewed some of the accomplishments during 2Rl0 in the area of protection from exposure including new SG protective clothing for personnel working in or near the internals and use of a new method for venting the SGs at the removal of the man-ways. However, a containment ventilation isolation notice was received with reference to work performed on SG-4 during 2R10. In concluding his presentation to the Committee, Mr. Hite SG observed that exposure results for 2R10 included the lowest bowl dose rates experienced at DCPP, low dose rates overall for SG work and for 2R10 as a whole, with a total of 44 contaminations. Mr. Hite noted that good results were RCS achieved with Residual Heat Removal(RHR)System flushes and chemistry cleanup and he provided charts with data to support his observations. He discussed with the Committee the impact of zinc injection on dose reduction chemistry. Mr. Womack remarked that it was his belief that DCPP was the first results pressurized water reactor to inject zinc and that the on dosage chemistry and on primary water stress corrosion cracking (PWSCC)within the SGs has been beneficial. A short break followed this presentation. Vice President Womack introduced Employee Concerns to Program Supervisor Rich Cheney for the next presentation the Committee. B. 9-12
Results of the December 2000 Comprehensive Cultural Assessment. Mr. Cheney stated that a Comprehensive Cultural Assessment(CCA) survey was conducted by Synergy, Inc. during November-December 2000, and included 40 on-site interviews with DCPP employees. The CCA survey was designed by Synergy to provide a comparison to the previous survey Synergy the conducted at DCPP during 1998. He reported that 81% of questions asked during the 2000 CCA were comparable to those from the 1998 survey. Results of the 2000 CCA were also compared to those from twelve other plants in Synergy's database to provide DCPP with a ranking within the industry. Mr. Cheney noted that the 80.4% response rate to the 2000 CCA he exceeded the 61.8% response rate to the 1998/99 CCA and used by Synergy to rank and reviewed the scope and methodology trend response to the 2000 CCA survey. of Mr. Cheney then summarized the results and conclusions Synergy's 2000 CCA for DCPP and he compared the responses received from the major organizations within DCPP. Nuclear is Safety Culture(NSC)was rated as good to very good and 1998 CCA. perceived as having improved notably since the Nuclear safety values, behavior and practices, a composite to have indicator, rated as good to very good and is perceived improved notably. Safety Conscious Work. Environment(SCWE) rated as very good to excellent and is perceived to have improved notably. The Employee Concerns Program(ECP)rated as However, adequate to good and is perceived to have improved. lower than nuclear safety values the ECP was rated uniformly or the SCWE by all DCPP organizations. Mr. Cheney observed the that on an industry-wide basis DCPP's NSC ranks around Relative strengths for DCPP in the area of 70th percentile. NSC include SCWE, nuclear safety priorities, operational nuclear safety and the CAP. Relative weaknesses identified in the area of NSC include employee confidence in decisions concerning allocation of resources to assure nuclear safety, confidence in the ECP and its effectiveness, and the timeliness and overall effectiveness of the Action Request(AR)process. Mr. Cheney discussed these results with Rossin the Members and, in response to a question from Drs. and de Planque, he promised to clarify the display chart the containing the industry comparison data and replied that to the methodology and responses are subjective in regards relative strength or weakness of a particular area. In Cheney confirmed that response to a query from Mr. Clark, Mr. might be a result responses concerning allocation of resources the of forward-looking thinking by some employees concerning California energy situation and its potential impact on DCPP. B.9-13
take Mr. Cheney noted that DCPP employees' willingness to the appropriate action was rated very good to excellent and safety issues or environment for raising potential nuclear with front quality concerns was rated very good, especially of the mix line supervisors. Vice President Womack noted that people of survey respondents, approximately 80% of the 1,300 really consistently work who responded to the survey do not control by the within areas of DCPP which are subject to core Quality Assurance(QA) organization and are not, as a Non function of their jobs, involved in initiating ARs or nuclear-safety related Conformance Reports (NCRs) involving issues. SCWE indicators and precursor ratings for management and supervision improved from the 1998 CCA. The four DCPP in the organizations with the relative lowest SCWE ratings the 1998 CCA improved significantly. DCPP site rating for ECP improved 4%, however, the ECP overall effectiveness of the declined. Mr. Cheney rating by Operations shift personnel related stated that this was believed by PG&E to be directly who to the aftermath of the removal of a DCPP Shift Foreman the raised safety concerns with DCPP management, the DCISC, local media and in several other public forums. Mr. Cheney noted that, of the 8 division-level CCA, 7 organizations targeted for improvement by the 1998 while showed significant or notable improvement in the NSC shown improvement. In response only shift operations had not to to a question from Dr. Rossin concerning future tracking Mr. Cheney follow the process-based reorganization at DCPP, to and Mr. Womack replied that DCPP will retain the ability results and they collect and monitor comparable and meaningful that confirmed, in response to an observation by Mr. Clark, PG&E will begin work to identify function and to monitor Excellence results against DCPP's new process-based Centers of organizational framework. Mr. Cheney observed that CCA significant progress was achieved for most of the 1998 Only 2 of the 8 continue to be targeted organization. the 2000 CCA NSC results. A total of 4 targeted based upon based organizations are designated as targeted organizations are the Shift Operations, upon the 2000 CCA NSC results, these Supply Control Room Electrical Maintenance, Nuclear Steam System(NSSS) Maintenance and Procedure Services organizations. The general culture work environment was rated as CCA, which adequate to good by those participating in the 2000 the 1998 Synergy identified as a notable improving trend since CCA. DCPP ranks approximately in the 68th percentile in the industry for general culture work environment. Areas of relative strength included keeping a focus on continuous high improvement, conduct of work and work practices, B.9-14
standards, an environment of dignity, trust and respect, teamwork and industrial safety. Areas identified as development, job weaknesses include communications, personnel satisfaction and morale, management of change, performance Of 8 recognition and responsiveness to the 1998 CCA. organizations targeted by the 1998 CCA, 7 showed improvement, while Shift Operations demonstrated a decline. Mr. Cheney reported that leadership, management and by supervision were rated as adequate and were perceived Synergy as improving since the 1998 CCA. Areas of relative strength included leadership's ensuring high standards, and supportive work environment for openness and receptivity promoting and demonstrating teamwork. Areas of relative weakness include management of change, establishment of effective plans, providing direction and building confidence in in management, setting a good example and building trust management, personnel management and promoting employee involvement. Of the 8 organizations targeted by the 1998 CCA, Operations 6 showed improvement, 1 showed no change and Shift showed a nominal decline. In concluding his presentation, Mr. Cheney observed that in the significant progress was achieved since the 1998 CCA organizations targeted for general culture work environment CCA improvement and only 3 of the 8 targeted by the 1998 continue to be targeted based upon the 2000 CCA. Organizations targeted for general culture work environment Control improvement by the 2000 CCA include Shift Operations, General Services and Room Maintenance, Procurement Services, Significant progress was achieved for most Security Services. leadership, of the 1998 CCA targeted organizations concerning skills improvement, however 4 of management and supervisory CCA. the 8 continue to be targeted based upon the 2000 management and Organizations targeted for leadership, supervisory skills improvement include Shift Operations, Control Room Maintenance, Security Services, General Services, Team, Procurement Services, Scheduling, Maintenance Support Other Maintenance, ATUR Maintenance and NSSS Maintenance. and Progress was achieved on each of the 5 general culture of the 2 work environment-related issues and on each leadership, management and supervisory skills issues CCA. Mr. Cheney pointed out that identified by the 1998 that the full benefits of the Synergy specifically concluded to embrace and reinforce the new value ongoing initiative system at DCPP have yet to be realized. He observed that the average, scores from the bargaining unit employees were, on and that 9%-10% lower than the rest of the site population the lowest in their experience. Synergy noted that these were B.9-15
Members and consultants discussed with Mr. Cheney and Vice President Womack possible reasons for the CCA results and their observations concerning the 2000 CCA by Synergy. Mr. Cheney discussed and reviewed results of 3 areas of special analysis by Synergy in the 2000 CCA including industrial safety, responsiveness to the 1998 CCA and progress on selected management initiatives. Mr. Clark requested a copy of the written comments from the interviews used by Synergy in their 2000 CCA special analyses. In response to a question from Mr. Clark, Mr. Cheney remarked that he was not particularly surprised by the results of the most recent Synergy CCA. Vice President Womack remarked that he was surprised that Operations sustained its position as a leader in the organization from a safety culture perspective but did not progress, as did other organizations, in either the general culture or the leadership, management and supervisory skills areas. Dr. de Planque requested Mr. Cheney to determine if the INPO rankings were public information and to explore, if possible, any correlation between INPO's and Synergy's results. Mr. Womack observed that PG&E is presently considering options for actions in response to the 2000 Synergy CAA and Mr. Cheney discussed with Consultant Booker some of proposals addressed to the EAP. Mr. Clark discussed with Mr. Womack PG&E's plans and the options available and under consideration to following up the results of the 2000 CCA and Mr. Womack confirmed to Dr. Rossin that the results of the Synergy 2000 CCA survey were presented to the DCPP organization. XIV PUBLIC COMMENTS AND COMMUNICATIONS Mr. Clark invited any member of the public present who wished to address the Committee to do so at this time. Ms. June von Ruden, a resident of Pismo Beach, was recognized to address remarks to the Committee and to PG&E representatives present. Ms. von Ruden observed that she has addressed remarks to the Committee and PG&E in the past and expressed her belief that the forum provided by the Committee is a valuable one and that it was unfortunate that more members of the public did not choose to attend the public meetings. She suggested that a public comment period at the beginning of a DCISC public meeting might be valuable for those who cannot wait until the scheduled presentations for a session have concluded. She also noted that the use of the reference to "Technical Presentations" in the notices of meetings of the Committee might discourage some from attending its meetings. B. 9-16
Ms. von Ruden reported that a staff person from DCPP had sent her a letter in April to express concern over the Synergy report and the characterization in that report of certain aspects of DCPP operations as "adequate" or "nominally adequate." She stated that the writer expressed concern over working conditions and lack of ability to interface with DCPP management. She stated that her contact also expressed a and belief that the Employee Concerns Program(ECP)was useless that DCPP employees harbor significant mistrust of PG&E and the NRC. Her source alleged that management's actions were resulting in very significant levels of stress on the DCPP workforce and that outage operations were given a higher priority by PG&E than employee stress and fatigue. Ms. von Ruden stated that she would provide the DCISC with a copy of the letter, after blocking out identifying information, and she urged the Committee to give it serious consideration and she stated that it was her impression that its author was not motivated by anger nor vindictiveness toward PG&E. The Chair thanked Ms. von Ruden for her comments and her attendance at the meeting and observed that a copy of the letter would be of interest to the Committee, provided that Ms. von Ruden was satisfied the author wished it to be shared with the Committee. The Chair and the Members agreed to take Ms. von Ruden's suggestions concerning a specific time for public comments on the meeting agenda and the wording of the notice for the public meetings under advisement. XV ADJOURN AFTERNOON MEETING The afternoon public meeting of the Diablo Canyon at Independent Safety Committee was adjourned by the Chair 4:59 P.M. XVI RECONVENE FOR EVENING MEETING Mr. Clark called to order the evening public meeting of the DCISC at 5:30 P.M. XVII COMMITTEE MEMBER COMMENTS The Chair reconvened the evening meeting of the DCISC and asked PG&E Vice president Larry Womack to continue the technical presentations to the Committee. XVIII INFORMATION ITEMS BEFORE THE COMMITTEE (Cont'd.) Vice President Womack remarked that Vice President-B. 9-17
David Oatley was Diablo Canyon Operations and Plant Manager the INPO unable to attend this meeting as he was attending programs and Accreditation Board review for 6 DCPP operating accreditation of noted that INPO has unanimously renewed their DCPP programs. Update on Plant Performance and Operational Status. public Mr. Womack noted that the period since the last with regard meeting of the DCISC have been largely uneventful to DCPP power generation operations. He observed that during on each that time period turbine valve testing was performed 2R10. Total Plant Unit and U-2 successfully completed in DCPP generation during March 2001 was the greatest operating history. In response to a query from Dr. Rossin, in the Mr. Womack replied that while he was not involved belief that either communication it was his understanding and Governor's office did call the Governor or someone from the PG&E's CEO or President to request that DCPP return to power as planned in and not curtail generation to 20% on both Units however, anticipation of Pacific Ocean storm activity, as planned. Vice President Womack generation was reduced during the period since the reviewed operational activities last public meeting of the DCISC, these included: of

Members asked several questions during Mr. Womack's operational review. B.9 -18
Review of DCISC Selected Performance Indicators Vice President Womack discussed and reviewed with the Members and Consultants the 21 indicators currently being tracked at the request of the DCISC to measure DCPP performance. He summarized their status through the end of April 2001, as follows (a indicates an improving trend, T indicates a declining trend and v indicates a steady performance since last reported to the Committee): Thirteen of the indicators are on or better than the target. a Radiation Exposure.

Members and Consultants discussed with Mr. Womack the including results and trends demonstrated by the indicators the substantial reduction in the efforts made in achieving collective radiation exposures since DCPP began commercial power generation activities in 1987. Members and Consultants reporting discussed with Mr. Womack some of the constraints to publicly on the results and status of the industry performance indicators used by INPO. Vice President Womack briefly summarized and reviewed with the Members the activities of NSOC and PG&E's President's public meeting Nuclear Advisory Committee(PNAC)since the last of the Committee in February 2001. Activities of PG&E's Nuclear Safety Oversight Committees. of Vice President Womack reported that a regular meeting progress, on NSOC was convened at DCPP, with outage 2R10 in May 2, 2001. Topics discussed during that meeting included the INPO results, the impact of the bankruptcy proceedings, and a report from the NSOC proposed reorganization of NSOC Mr. Womack Subcommittee on Oversight and Corrective Actions. and its report as characterized the Subcommittee's activities of other successful and useful and he remarked that the use of subcommittees, as well as ad hoc or standing committees, use in the future. Other NSOC will be considered by PG&E for included a topics reviewed during the May 2, 2001 NSOC meeting Accident License Amendment Request(LAR) to eliminate the Post conducted Sampling System(PASS), the results of the CCA survey performance results from the by Synergy, a review of human Integrated Assessment Report(IAR) and plans for 2R10. Dr. de Planque reported briefly on her attendance with NSOC. She Consultant Wardell at the May 2, 2001 meeting of there was a lack of critical remarked on her observation that of NSOC, dialogue on the part of some of the outside members organization. She those members of NSOC from outside the PG&E that noted that the DCISC has recommended to PG&E management it encourage all the members, particularly the outside analytical members, of NSOC to take an active, questioning and She noted that while approach to their participation on NSOC. is two of the external members on NSOC are new, there Committee. currently only one truly independent member of that the value of the STARS While she stated that she recognized cooperative efforts, she encouraged PG&E to joint utility membership to consider adding additional independent outside NSOC. Vice President Womack replied that the DCISC PG&E and recommendation was presently under consideration by he reviewed some of the other proposed changes in the B.9-20
composition of NSOC. Mr. Clark observed that the DCISC is presently considering how to continue and to improve its re-examination of issues relative to human performance. Mr. Womack opined that the first step in any such re-examination should be to establish objectives and to select participants. Mr. Womack reported that a regular meeting of PNAC was held at PG&E's San Francisco Headquarters on April 9, 2001. Topics discussed during that meeting included Reportable Events, Notice of Violations, NRC issues and the NRC Reactor Oversight Program(ROP) performance indicators. PNAC also reviewed the Quality Performance and Assessment Report(QPAR) and the activities of NQS. Members of PNAC discussed recent activities of the DCISC, events and status concerning PG&E's Humboldt Bay Nuclear Power Plant, the Integrated Plant Assessment Report, preparations for 2R10 and the results of the Synergy 2000 CCA survey of DCPP. Vice President Womack then requested Manager of Regulatory Services Pat Nugent to make the next presentation to the Committee. Review of Reportable Events and Notices of Violation. Mr. Nugent reviewed the first of two Reportable Events, which occurred at DCPP since the last public meeting of the DCISC in February 2001. He noted that one LER involved equipment failure and both involved inadequate procedures. A single LER was initiated for wires, which were found to be degraded in vital switchgear cubicles in 4.16kV vital buses. The degradation was identified when a containment spray pump breaker failed a test and it was determined that the cause of the failure was short-radius bending of a wire near cubicle door hinges, resulting in a break in the wire and causing an over current trip on the breaker. All cubicles were inspected and degraded wires were replaced. In response to a question from Dr. Rossin, Mr. Nugent observed that the cubicle design is a typical General Electric design and, although PG&E has consulted with other plants concerning this issue, no indication of widespread failures of this type have been reported in the industry. The final cause analysis will determine the long-term corrective actions, which will include a Preventative Maintenance Program for the wiring. It was subsequently determined that Technical Specification (TS)3.0.3 was violated when, during repair of the degraded wires, two sources of offsite power supply and the EDG to Bus-H were inadvertently made inoperable without formal entry into TS B.9-21
3.0.3. The cause was determined to have been confusing to procedures related to offsite power, which caused operators thus leave the transformer tap-changer in the wrong position, source. Mr. causing potential inoperability of a startup Plant Nugent replied to a question from Dr. Rossin that the diesel was in a TS mandated Eight Hour Action Statement for 1 at the time, rather than 1 and 1 offsite source inoperable TS 3.0.3 would have diesel and 2 offsite sources inoperable. shutdown of required one hour to make preparation for orderly the Units or for resolution of the TS issue. Mr. Nugent confirmed an observation by Consultant Booker that this event could constitute a potential Notice of Violation (NOV), however, he noted that the event was within the single failure criteria of the design basis such that even with the degraded the wire, some other failure had to occur in order to make degraded condition of the wire affect DCPP operations. Actions taken in response to the event include upgrading procedures and training operators. In response to a question from Mr. Clark, Mr. Nugent commented that the NRC determined the event to be of relatively low safety significance, however, he observed that PG&E was troubled by the fact that the the operators' knowledge did not permit them to recognize Dr. Rossin questioned whether situation until after the fact. the System Engineer had the opportunity, following this event, to undertake an objective and in depth analysis of other events, unrelated to the breaker cubicles, which might contribute to a similar result. Mr. Nugent replied that, while the LER evaluates immediate influences on other is a potential situations related to the breaker cubicles, it difficult task to comprehensively address all the broader to electrical configuration. Vice issues which may be related President Womack observed that DCPP entered into this operational evolution with full participation and review by Engineering and Maintenance and that, while this situation was (SAR), not specifically analyzed in the Safety Analysis Report have been the implications of the tap changer settings should identified beforehand. He stated that this situation fell available to short of PG&E's expectations regarding guidance seek operators and concerning the operators' willingness to further guidance, if necessary, during off-normal operations. A second LER was initiated when DCPP experienced an automatic EDG anticipatory start due to a wildland fire and loss of 230kV startup power. Heavy smoke from a CDF planned burn caused phase-to-phase arcing and tripping of 230kV startup power lines and EDGs for U-1 and U-2 started automatically but did not load. An Unusual Event was declared. The cause was determined to be inadequate DCPP administrative controls and inadequate oversight by burning operations by the personnel of the cutting and brush B. 9-22
CDF crews. CDF initiated changes to the normal burn pattern used in the vicinity of DCPP without consultation with PG&E. Actions taken in response include generating new procedural guidance to address PG&E oversight and expectations for CDF vegetation management activities. DCPP remained connected to the 500kV system and both Units remained at full power during the event. Mr. Nugent reviewed and discussed violations and findings received from the NRC since the last public meeting of the DCISC. There were 0 NOVs, 4 non-cited violations(NCVs) and 1 finding during that period. The first NCV discussed involved a violation of the Physical Security Plan for failure to follow warehouse access control requirements. A second NCV was received for a violation of 10 Code of Federal Regulation(CFR)50, Appendix B, for leakage of Component Cooling Water(CCW) system train boundary valves, resulting in the CCW system being operated outside design basis. A third NCV was received for a violation of 10CFR20.1501 for failure to follow procedure when a radiation technician left the area without performing the required radiation area survey associated with the replacement of the spent resin filter when that task took longer than planned to accomplish. A fourth NCV was received for violation of TS 5.4.1.a for failure to follow procedure RCP D 614 when two incidents of radioactive materials being found outside of the Radiological Controlled Area(RCA)were identified. In response to a question from Consultant Booker, Mr. Nugent and Mr. Ketelsen confirmed that PG&E is conducting a root cause analysis and determining corrective actions for each self-identified NCV. Mr. Nugent observed that the NRC issued a finding for failure to perform a Maintenance Preventable Functional Failure Review prior to closure of a tracking AR for inadvertent removal from service of Startup Transformer 2-1. Committee Members observed that all but one of the NCVs and the finding discussed involved some form of human performance failure. In concluding this portion of his presentation, Mr. Nugent observed that during 2001, in comparison with NRC Region IV plants, DCPP has received 0 NOVs while the Region IV average is 0.14, while DCPP received 4 NCVs as compared to the Region IV average of 4. Since 1999, NCVs for DCPP have dropped from 34 in 1999 to 17 in 2000 to 4 to date in 2001. In response to a question from Dr. de Planque, Mr. Nugent observed that the NRC has changed its oversight process and that this change was primarily responsible for the downward trend in NCVs from 1999 to 2000. Mr. Stan Ketelsen noted that, with reference to the wildfire burn which resulted in an LER, the fire was separated B.9-23
from the 500kV lines (the second off-site power source) by a significant distance as well as by the wind direction. Mr. Nugent reviewed the status of some of the NRC Performance Indicators(PIs). These indicators produce red, white or green status indications for levels of performance evaluation for the indicators in each category. He reviewed with the Committee the current status and recent actions relative to certain of the PIs. He reported that all DCPP PIs are currently in green status, however, the two trips PI following 1R10 currently challenge the Unplanned Scrams threshold for entering white status. Both Units are at the threshold between green and white status for scrams with Loss of Normal Heat Removal PI and he noted that this is due to kelp loading on the traveling screens at the Intake Structure and is beyond DCPP's ability to control. PG&E has submitted a question to the NRC relative to the treatment of these events and their effect on the PIs and he briefly discussed PG&E's the efforts to anticipate the effect of storm-loaded debris on that DCPP was traveling screens with the Members. He reported involved in the NRC's implementing pilot program concerning Initiating Events. He noted that a revision of NEI 99-02, the implementation guideline for the Revised Reactor Oversight Program(ROP), has been adopted, which incorporated answers to some 200+ NRC-approved Frequently Asked Questions to clarify the PIs. Mr. Clark noted that the binder of exhibits prepared by PG&E for the public meeting contains a report on the PIs, their present value, the NRC threshold and present color status for the PIs for both operating Units at DCPP and the station thresholds set by PG&E for the PIs through the first quarter of 2001. Members and consultants questioned Mr. Nugent concerning the Emergency Preparedness data: Category - Emergency Preparedness (a) Emergency Response Organization(ERO)Drill/Exercise Performance - percentage of success/opportunities for notifications and Protective Action Recommendations(PARS) during drills, exercises and events of the past 8 quarters. Value for U-1 and U-2 combined is 92.6% and the NRC threshold is not less than 90%. Status Green. Station threshold is 95%. ERO Participation - percentage of key ERO personnel that (b) B.9-24

Reliability - percentage (c) Alert and Notification System reliability during the previous 4 quarters. is 99.4% and the NRC Value for U-i and U-2 combined Station 94%. Status - Green. threshold is not less than threshold is 98%. exceeded the station threshold Mr. Booker noted that PG&E has noted that PG&E is trying to for item (a) above and Mr. Nugent indicator by conducting improve with reference to that with the personnel involved tabletop training exercises for notifications and concerning time requirements He noted that the making PARs. requirements associated with Operations Facility staff has composition of the Emergency making PARs facilitate been changed in order to better have been additional drills notifications on time and that data used in scheduled. Mr. Womack noted that the numerical into account consequences or that indicator does not take licensees into actions which potential consequences and forces benefit for may not necessarily return significant PG&E is striving for that public safety, however, he noted several 100% performance. Members and consultants discussed with Mr. Nugent and Vice of the aspects of this indicator President Womack. Mr. Clark inquired Following Mr. Nugent's presentation, at the for DCPP of a recent event concerning the implications which involved a Westinghouse North Anna nuclear facility, has evaluated and fuel assembly. Mr. Womack replied that DCPP a fuel assembly coming reviewed the event, which involved is not susceptible to a apart, and determined that DCPP in fuel design. Mr. similar type event due to differences for might be a potential issue Clark noted that this event for the next DCPP review in conjunction with planning refueling outage.

XX ADJOURN EVENING SESSION The evening meeting of the Diablo Canyon Independent Safety Committee was adjourned by the Chair at 7:18 P.M. XXI RECONVENE FOR MORNING SESSION The June 21, 2001 meeting of the Diablo Canyon Independent Safety Committee was called to order by the Chair at 8:30 A.M. XXII INTRODUCTORY COMMENTS BY COMMITTEE MEMBERS Mr. Clark introduced the Members and consultants present and requested Vice President of Operations David Oatley to introduce the next technical presentation requested by the DCISC. XXIII INFORMATION ITEMS BEFORE THE COMMITTEE (Cont'd.) PG&E Bankruptcy Status and Impact on Diablo Canyon. Mr. Oatley reviewed events during 2001 which resulted in PG&E's filing for Chapter 11 bankruptcy protection in federal court. He reviewed the prices for electric power procurement in California which have escalated from $7 billion in 1999 to $25 billion in 2000 to an estimated $50-$60 billion for 2001. He stated that at the end of 2000, PG&E was losing an estimated $3-$4 million per hour on the difference between the price paid for electric power and the price allowed by the regulators to be passed on to the customer. The extremely large debt accumulation, approximately $9 billion by January 2001, made it impossible for PG&E to pay for past energy purchases from suppliers or to secure financing for further power purchases and, accordingly, the State of California through its Department of Water and Power Resources began procuring energy for California investor-owned utilities by the end of January 2001. The State now provides PG&E with additional energy required to supply customers, beyond that which PG&E produces through operation of its remaining generating facilities. In response to a query from Dr. Rossin, Mr. Oatley confirmed that PG&E sold all power through California's Independent System Operator and the Power Exchange, until the Power Exchange ceased operation. PG&E bid DCPP power at $35.00 per megawatt hour and additional needs are supplied by the State at a cost of between $200-$400 per megawatt hour. Mr. Oatley noted that PG&E had $500 million in cash, the minimum required for operations, when default was B.9-26
sought on April 6, 2001. declared and bankruptcy protection to discussions held just prior Mr. Oatley briefly described office of the Governor, wherein April 6, between PG&E and the the bankruptcy. He discussed he stated PG&E attempted to avert lack in those negotiations, PG&E's the delays which took place of interest in selling its transmission system, the CPUC's eventually payable to PG&E by decision to raise electric rates of rates paid to the Department 3¢ per kilowatt hour and the hour. PG&E by 4¢ per kilowatt Water and Power Resources by that PG&E does not view Vice President Oatley stated but as an end in itself, Chapter 11 bankruptcy protection relatively must pass through rather as a portal the utility vigor. The bankruptcy format quickly to restore economic provide a more consistent frame should, in PG&E's estimation, necessary to move forward. work in which to make the decisions strategy as twofold: 1) work He described PG&E's bankruptcy
- 2) stabilize the business. He through Chapter 11 quickly, and described DCPP's priorities concerning the bankruptcy to do whatever necessary situation as threefold: 1) continue
- 2) continue to do whatever to operate safely and reliably, to sustain a Number 1 ranking necessary to support activities to improve and maintain by INPO, and 3) to continue activities DCPP training programs.
effects of the Mr. Oatley briefly reviewed the include the need to receive declaration of bankruptcy which paying wages and benefits to judicial permission to continue in weekly contact with the NRC PG&E employees. DCPP has been and to monitor any impacts concerning DCPP operational issues that PG&E from the utility's financial situation. He reported billion on hand, with pre currently has approximately $2.7 be
$9 billion to petition payables of approximately currently estimates the PG&E adjudicated in the bankruptcy.
one to four years to fully bankruptcy proceedings may take issues before the court. PG&E resolve the complex and numerous approval for a retention plan currently has a petition pending Mr. Oatley reported that DCPP for key management employees and on account of the has not, thus far, lost any personnel a reorganization plan bankruptcy. The first date for filing is August 5, 2001, and Vice in the bankruptcy proceeding there is a creditors' committee President Oatley remarked that of PG&E's creditors and which now represents the interests during a 60-day period, which will participate in negotiating, he of the reorganization plan and with PG&E concerning details a filing in excess of noted that committee has submitted by the court. 27,000 pages for consideration believes there to be four Mr. Oatley observed that PG&E successful reorganization: 1) fundamental options to achieve B.9-27
raising rates to match costs and recover debts, 2) reduce or eliminate payment to some or all creditors, 3) sale of PG&E's assets, or 4) utilize existing assets in a different manner to generate revenue. In response to a question from Mr. Clark, Vice President Oatley responded that the impact on DCPP of the bankruptcy filing, to date, has been very minimal with no reduction in staff and only a minimal number of non-core business activities deferred. The bankruptcy situation has had no impact on decisions concerning required maintenance and there has been no deferral of preventative or corrective maintenance tasks. He noted that there was no change or alteration in the schedule, budget or the scope of activities planned and accomplished during 2R10. Management initially met with managers and directors on a daily basis to discuss information received and on a weekly basis to review PG&E's current status and options. Brown Bag lunch meetings have been held every Friday with employees to allow them to ask questions of management. Mr. Oatley stated that PG&E is also placing special emphasis on human performance safety programs and has seen a reduction in the rate of human errors during and since 2R10. The industrial safety rate is comparable to the previous year, however, disabling and recordable injury rates are trending significantly lower. In response to a question from Consultant Booker, Mr. Oatley replied that, to date, there has been no reluctance on the part of DCPP's contractors to continue to supply DCPP. He noted that diesel fuel for the EDGs was in short supply due to the rotating outages affecting oil refineries in Northern California, however, PG&E obtained a supply of diesel fuel from a Southern California refinery which was not subject to the outages. He noted that DCPP has developed an energy crisis contingency plan, using some of the process and data developed for the Y2K Program, to identify critical suppliers and backup sources necessary to operate the Plant safety and reliably. As a part of energy crisis contingency planning, DCPP has developed internal policies for addressing requests for actions impacting generation received from any State agency. Members and consultants discussed with Mr. Oatley the regulatory requirement to maintain a 7-day supply of diesel oil on hand at DCPP at all times and some of the strategies devised to meet that consideration. In response to a question from Mr. Clark, Vice President Oatley noted that PG&E analyzed and performed NQS audits concerning operability issues on the 230kV and 500kV off-site power systems and determined there was no effect on DCPP generation operations from the rotating outages occurring on the 115kV transmission system around California. The emergency warning siren system has been placed B.9-28

Communication, Pages 34-40, (See Public Comments and of the audience, Mr. Following comments from members Storage Manager for the Used Fuel Oatley requested the Program presentation to to make the next Project, Mr. Jearl Strickland the DCISC. of Spent Fuel. Status and Plans for Dry Cask Storage update on the status of the Mr. Strickland began this with an overview of that Used Fuel Dry Storage Project the NRC is currently licensed by Project. He noted that DCPP 2025 for year 2021 for U-I and until for operations until the using wet storage stored on site U-2. Used fuel is currently in a vertical stacking configuration technology, underwater in wet storage capacity was added the Spent Fuel Pool. Additional and he noted that, at present, for DCPP fuel during the 1980's capacity to serve DCPP until there is only enough on site reviewing options for 2006. PG&E management, after wet storage capacity at DCPP, reconfiguring and extending for development and Holtec selected a dry storage option as the NRC-licensed dry International has been selected will proposed dry storage facility storage system vendor. The units which is sufficient accommodate up to 138 storage handle all fuel pools off-loaded, to capacity, with the spent period for fuel through the end of the current licensing spent the reviewed the placement of both Units. Mr. Strickland is proposed for an area facility at the Plant site, which of the during construction which was excavated previously soil and and 230kV switchyards and, accordingly, its 500kV the similar to that upon which rock composition, which are B. 9-29
DCPP power block rests, as well as its seismic properties, are well understood. He observed that the dry storage facility would be constructed in a sequenced manner and would eventually have 7 pads, accommodating up to 20 storage units each. Mr. Strickland stated that the Holtec long-term storage system is comprised of 3 major components: the transport cask; the storage overpack, comprised of 2 steel vessels; and the multi-purpose cannister which can accommodate up to 32 stored fuel assemblies. He reviewed with the Committee the process proposed for storing the spent fuel. Mr. Strickland observed that DCPP site-specific seismic considerations have prompted PG&E to request of Holtec a design modification for the DCPP configured storage facility which will anchor the overpack to the concrete pad using anchor bolts. Mr. Strickland reviewed and discussed with the DCISC the project's current status as follows: a contract with Holtec is presently being negotiated and is close to being finalized; the environmental reports are essentially complete; the Safety Analysis Report(SAR) is complete, with the exception of the geotechnical sections; Part 72 Technical Specifications are complete and are being reviewed by the Plant Staff Review Committee(PSRC);and the Security Plan modifications are in draft form. Mr. Strickland reviewed project delays which were caused principally by PG&E's corporate financial status, unique geotechnical issues related to the site characterization and slope stability, the design of the foundation and the design of the cask transfer facility. The NRC has requested additional information concerning the Holtec High Seismic license submittal. He reviewed the project schedule and noted that facility construction is expected to finish by 2005, and he identified the milestones in obtaining regulatory approval as NRC Facility Development(10 CFR Part
- 72) submittal in August 2001, NRC Power Plant Modifications(10 CFR Part 50) submittals and Coastal Development Permit application submittal in September 2001. In response to a question from Consultant Booker, Mr. Strickland replied that the PSRC has reviewed the environmental reports and all aspects of the SAR except geotechnical.
In conclusion, Mr. Strickland noted that information has been and is continuing to be provided to members of the public concerning this project. PG&E has posted a website at www.pge.com/diablocanyon to provide information and to receive and answer questions. PG&E provided briefings to various local interest groups and he noted that the regulatory review process also provides a separate venue for public input into the project. In response to a question from Consultant B.9-30
that the proposed DCPP design Wardell, Mr. Strickland replied to the pad has enhanced modification anchoring the overpack without a the ability of the system to receive qualification and toppling similar need to address the sliding using the Holtec facilities considerations as at other nuclear multi-purpose canisters are System. He noted that while the designed to be air tight, the overpack has vents for natural that regulations do not convection cooling. He also observed to maintain a separate presently require the facility from that currently radiation monitoring system, apart at DCPP perimeter existing and maintained for dosimetry review the SAR and fences. The Committee requested to are available and Mr. environmental reports when they probably be sometime during Strickland confirmed that would confirmed, in response to a September 2001. Mr. Strickland there would be a few degrees of question from Dr. Rossin, that outside of the storage units difference in temperature on the and he promised to from the ambient surrounding temperature review with Holtec their choice of a helium atmosphere for their response to the their storage design and to provide Committee. A short break followed. the Chair again When the Committee was again seated, present to address recognized some members of the audience remarks to the DCISC. (See Public Comment and Communication, Pages 34-40, below.) to the Committee that PG&E Vice President Oatley reported would have been plugged in the there were 852 SG tubes which not received approval. SGs had the Alternate Repair Criteria two 50,000 gallon diesel fuel He also reported that DCPP has of fuel available when tanks, for a total of 100,000 gallons that actual diesel filled to capacity, for the EDGs. He noted to drop below 65,000 fuel storage inventory is not permitted by TS for 7 days gallons, which is the amount required operation. Manager of Regulatory Mr. Oatley then introduced DCPP next presentation to the Services Pat Nugent to make the Committee. of the Status Update on Proposed Removal Post-Accident Sampling System. for a License Mr. Nugent stated that PG&E applied the requirement for the Post Amendment from the NRC to remove at DCPP. PG&E made the request Accident Sampling System (PASS) B. 9-31
because the PASS samples do not provide timely information following an accident and because on-line instrumentation is available to monitor core damage in real time. He stated that a Westinghouse performed evaluation concluded that there was no reason to continue the PASS at DCPP and he noted that the NRC has initiated a new process termed the Consolidated Line Item Improvement Process (CLIIP) in order to address applications for license amendments received from DCPP and other utilities concerning elimination of PASS requirements. PASS CLIIP was announced in the Federal Register on October 31, 2000, and provides a one year window of opportunity to submit License Amendment Requests (LARs) . CLIIP allows a licensee to request an amendment for a generic issue provided it meets the model safety evaluation and requested commitments. Mr. Nugent observed that the DCPP LAR makes three commitments, requested by PASS CLIIP, and he discussed these briefly: "* Development of Contingency Plans for Samples. "* Description Capability for Classifying Events at Alert Level. "* Establishment of Capability for Monitoring Radioactive Iodine. Mr. Nugent noted that all three of these commitments can be monitored on-line by using the radiation monitors on the Letdown System and the radiation and hydrogen monitors in Containment. In response to a question from Mr. Clark, Mr. Nugent confirmed that DCPP must demonstrate its capability with reference to each of the commitments. Mr. Nugent confirmed an observation by Dr. de Planque that technology has overtaken the original rationale for PASS. Vice President Oatley asked DCPP Operations Section Work Control Supervisor Mr. Jim Dye to make the next technical presentation to the Committee. Update re: On-Line Maintenance. Mr. Dye stated that, as the Work Control Supervisor for the Operations Section at DCPP, it was his task to monitor and schedule on-line maintenance during non-refueling outage periods. He briefly reviewed recent DCPP performance and operational milestones. He discussed recent process improvements which have included: improved TS implementation, with over 500 new maintenance tracking documents created or modified to track allowable outage time and cumulative out-of-B. 9-32
Control Room service time for safety-related components; and which improved enhancements which INPO noted as strengths operator distraction; Control Room professionalism and reduced by the operators to and an upgraded Work Around List for use efforts. Mr. Dye improve and focus maintenance and engineering Operator Work Around reviewed and provided an example of the DCPP is used to distribute List and discussed how the list resources. Process was Mr. Dye observed that the Storm Swell Warning and was used to an example of a recent process improvement for action assist in making decisions and taking positive operations due precautionary curtailment of power generation loading. He to storm swell activity and consequent debris utilized on two separate briefly described how the Process was minimize stress on occasions to curtail power operations and the Plant in the event of a trip. Mr. Dye provided examples of for on-line graphs created to show the rolling average schedule adherence maintenance activity and for trending considers as Category A performance. Mr. Dye stated that DCPP shutdown Work Items those items, which have potential Statements or with implications, are associated with TS Action characterized as probabilistic risk issues. Those items are perform any work on high priority and every effort is made to those items according to a strict schedule, to result in the least impact to the operating organization. risk management Mr. Dye observed that on-line maintenance to include not only control processes have been revised hazards but also external risks from internal plant trip with the weather, fires and other events. He reviewed cumulative risk Committee some of the charts used to track from maintenance activities for both Units over a two-year Wardell, Mr. period. In response to a question from Consultant increased use of on Dye and Mr. Oatley observed that, while increased risk, by line maintenance does create periods of on-line maintenance only scheduling and sequencing necessary the overall and minimizing the duration of those activities response to a risk is kept within acceptable limits. In observed that currently question from Dr. Rossin, Mr. Oatley modeled in the the risk of not doing maintenance is not response to a question Probabilistic Risk Assessment(PRA) . In opined that DCPP from Dr. de Planque, Mr. Dye and Mr. Oatley on-line maintenance activities are about average compared to that the PRA used at other nuclear power plants and they noted plants. DCPP differs from those used by other STARS the Committee Mr. Dye then reviewed and discussed with activities at DCPP some examples of recent on-line maintenance which maintenance including U-2 diesel expanded pre-outage B. 9-33
significantly reduced 2R10 diesel outage work scope and the ASW Flow Control Valve (FCV)-601 motor/actuator change out which entailed dual unit risk management coordination to ensure maximum access to all available heat-sink inventory. Mr. Dye also discussed maintenance challenges associated with forced outages including the U-2 feedwater heater bellows, U-2 generator lead box weld crack and the post lRl0 turbine balance shot. Mr. Dye then reviewed and discussed two of the lessons learned involving on-line maintenance efforts including revisions of fire control and risk management procedures, resulting from loss of 230kV power due to the planned burn in April 2001 and deferment of the U-2 containment scaffolding storage project from pre-outage to 2R10. He stated that new rules governing implementation of 10 CFR 50.59, which will affect on-line maintenance decisions and calculations of risk probability, will be effective as of July 2001, and that the development of the ORAM-Sentinel maintenance risk evaluation tool should be completed, and ORAM-Sentinel should be ready for implementation by November 2001. Mr. Dye noted that the Operations Department shift foremen have generally indicated their approval of ORAM-Sentinel. The Conunittee expressed its interest in reviewing implementation of ORAM-Sentinel during a fact-finding in November 2001. In response to a question from Consultant Wardell, Mr. Dye noted that power operations to meet the California energy situation have had some impact upon, and required flexibility from, DCPP on-line maintenance activities. Mr. Oatley observed that any work deferred due to California's energy supply considerations has not, to date, created reliability or safety issues for DCPP. XXIV PUBLIC COMMENTS AND COMMUNICATION Following Vice President Oatley's presentation (see Page 29 above) concerning the PG&E bankruptcy, the Chair recognized some members of the audience to address comments to the Committee. Ms. Sheila Baker of San Luis Obispo inquired if members from any of the unions at DCPP or any non-management DCPP personnel were invited to present information to the DCISC during its public meetings. The Chair replied that the Members and consultants meet with individual DCPP employees, including members of unions, when making fact-finding visits to the Plant site. Ms. Baker suggested that the Committee might wish to consider inviting members or representatives of the unions and other non-management personnel working at DCPP to speak to the Committee during its regular public meetings to open up the dialogue beyond what is achieved by having only PG&E B.9-34
the DCISC. Mr. Clark thanked management make presentations to that the Committee Ms. Baker for her comments and replied and will consider how to accepts Ms. Baker's suggestions and dialogue to all who better open the public meeting process the forum. Dr. Cass observed may wish to avail themselves of DCPP's union employees in that she recently met with some of her meetings indicated the Maintenance organization and, while effect on safety, that PG&E's efforts are having a positive may perceive that, given recent she recognized that the public between management and changes and events, a barrier exists employees at DCPP. Marshall The Chair then recognized Ms. Pam Director of the Environmental Heatheringthon, the Executive to the remarks Center in San Luis Obispo, to address Committee. for its promised Ms. Heatheringthon thanked the Committee her and expressed consideration of Ms. Baker's comments between PG&E and the Creditor's concern regarding negotiations Court and queried Committee established by the Bankruptcy plans might be presented for whether different reorganization that the focus of the consideration. The Chair observed proceedings, per se, but Committee is not on the bankruptcy to be operated safely. rather on whether DCPP will continue would very likely Mr. Clark confirmed that the Committee plan to assess if it review any proposed reorganization operations, however, the adequately supports safety of DCPP time. DCISC at this context for such a review is uncertain that the Committee is Legal Counsel Wellington confirmed situation. In response to continuing to monitor the bankruptcy Mr. Clark replied that the a question from Ms. Heatheringthon, PG&E's decision to seek DCISC had no prior notice concerning with the general public the protection in bankruptcy. Together the deregulations efforts Committee followed the progress of was aware of and had in California, accordingly the Committee concerning the California received presentations from PG&E options. Ms. energy situation and PG&E's possible the Members that the DCISC Heatheringthon closed by reminding the public and she bears a heavy responsibility to represent expressed her thanks to the Committee. cask storage plans at Following the presentation on dry DCPP (see Page 31 above), the Chair again recognized several to address remarks to the individuals present in the audience Committee. Morro Bay, was Mr. David Weisman, a resident of that he had become alarmed recognized by the Chair and stated Vice President Oatley during the presentation by PG&E B.9-35
concerning the bankruptcy situation concerning the availability of fuel for the DCPP emergency diesel generators, because of the possibility that the California electric supply system may not be adequate to handle demand over the coming summer months. Mr. Weisman questioned whether the expense of bringing in a tanker truck to ensure +/-n additional supply of diesel fuel was available was a legitimate concern, given the high cost and expense associated with the normal operation of DCPP. He questioned whether PG&E management, in making a decision whether to bring in a fuel truck, might feel pressured between the need for financial economy and the need to ensure a sufficient supply of diesel fuel. Mr. Clark observed that the Committee recognizes the tensions inherent in such decision-making and commented that PG&E's past actions have indicated their willingness to commit sufficient resources to safety. The Members each indicated that they were satisfied with Vice President Oatley's comments concerning the diesel fuel supply and storage issue. Dr. Rossin and the Chair remarked that the NRC, as well as the Committee, are paying particular attention to DCPP operations to identify any negative impact occasioned by the utility's bankruptcy and that adherence to formal technical specifications also creates an effective format to assure the safety of DCPP operations. Dr. de Planque observed that those specification also have significant built-in safety margins and they are based upon a cognitive, in-depth review of operational safety and she remarked that the Y2K preparations were largely directed at dealing with unpredictable variables and extreme scenarios and may serve very well to model responses to the current energy supply situation. Mr. Clark thanked Mr. Weisman for his comments and confirmed that the NRC does post the results of its periodic inspections on its website, generally at six week intervals. Ms. June von Ruden delivered to Legal Counsel Wellington a copy of the letter she discussed earlier with the Members. Ms. von Ruden remarked that it was her experience, as a long time resident of California, that emergency planning cannot wait until a crisis occurs. Ms. von Ruden noted that this particular day has been denoted as "Lights Out Day" by some organizations, a day when electricity users were being asked to join in a protest by curtailing their use of electricity for 4-5 hours and she questioned if that action might affect DCPP operations. Members replied that, as electricity demand normally varies drastically on a daily basis, it was highly unlikely that this protest would have any impact on generation facilities in California. Mr. David Weisman was again recognized and addressed remarks to the Committee. Mr. Weisman stated that it was his

He questioned storage were not being adequately for of a proposed storage facility whether the availability with at Yucca Mountain, coupled nuclear waste, to be located capacity at proposed increase in on-site dry cask storage the of licensing for DCPP and DCPP, might lead to an extension fundamental issues concerning require further debate on of continuing the use of nuclear viability and advisability waste. creation of more radioactive power and the consequent delay of remarked that he had questions concerning the He also and concerning the high temperature the geotechnical reports that it was buried by a landslide of stored fuel in the event by a event.

Mr. Clark remarked and that the very important questions job of articulating some the answers to Mr. time provide all Committee cannot at this and questions, however, he noted that the licensing Weisman's these questions be that all approval process requires forward. cask storage cannot move addressed or plans for dry Mr. Strickland's mentioned during He noted that the documents to address pertinent questions presentation will be required made available as those raised by Mr. Weisman and will be that such Dr. de Planque and Mr. Strickland noted to the public. considering of utilities although there are a number systems, no storage units for storage contracting with Holtec require a for DCPP and the NRC will have yet been fabricated before issuing any license to do so. Mr. public process in public that there may be a tendency Strickland acknowledged accept that dry cask storage to presentations concerning a possibility that there is still option as a fact, however, only approval or be approved PG&E's plans may not receive become significant revision or that other options might after B. 9-37
available for consideration. Mr. Strickland observed that DCPP has a unique history concerning long-term seismic considerations and design which has evolved over a long period of time. He observed that PG&E's commitment to DCPP seismic design safety includes maintaining a geosciences department which studies impacts from seismic events worldwide and provides significant benefits for the local area. Mr. Weisman observed that the lack of many members of the public at the public meetings of the DCISC may reflect the public's perception that PG&E's plans are already firm and any further discussion would necessarily concern only the technicalities of achieving a result which has already been determined and is beyond the ability of the public to have meaningful input into the matter. Ms. Pam Marshall Heatheringthon, present in the audience, was recognized. She questioned why Mr. Strickland was unable to respond concerning Holtec's use of helium in the storage canisters, to which Dr. Rossin responded that the need to use an inert gas for such purposes is well known and thoroughly understood and he stated his question concerned why Holtec selected the relatively rare helium rather than the more commonly available nitrogen for their purposes. Dr. Rossin confirmed, in response to an observation from Mr. Clark, that his question concerned the design only and that he had no question regarding the adequacy of helium for Holtec's purposes. Ms. Heatheringthon inquired if the power lines serving the 230kV and 500kV switchyard would pass over the proposed dry cask storage facility, to which Mr. Oatley responded that the matter would be analyzed in PG&E's regulatory applications and addressed in the environmental reports. Ms. June von Ruden then inquired whether, based upon earlier efforts she had been involved in, re-racking to change the capacity of the present Spent Fuel Pool was really a viable option for PG&E. She also remarked that an engineer who claimed to have been involved in the construction of the original Spent Fuel Pool rack configuration had informed her some 20 years ago that the steel in those racks had cracked. She also inquired whether the hillside located near the proposed dry cask storage facility was subject to the type of landslides common in the local area and she questioned whether the bolting process would be adequate to its purpose. She also inquired as to the cost of installing one canister on the pad and whether this work would be done by DCPP or PG&E's contractor personnel. Mr. Clark observed that the regulatory approval process requires soil sampling to determine the adequacy of the proposed site and the other issues raised by Ms. von Ruden would also be addressed by the approval B.9-38
confirmed that PG&E had processes. Vice President Oatley NRC during the 1980's concerning received a license from the Spent Fuel Pool, which its re-racking proposal for the future the proposal, and that any included public hearings on require of the racks would plans to change the configuration input. further NRC approvals and public the Committee and observed Ms. Fay Magilhill addressed the efforts being made to address that she was impressed with whether the Committee adequately safety, however, she inquired when reviewing safety of DCPP examines worst case scenarios that, if the Committee was operations. Mr. Clark confirmed public, it would have an aware of an undue risk to the the with PG&E, the NRC or with obligation to raise that issue de the DCISC's members. Dr. State agencies which appoint a that only the NRC could issue Planque and Mr. Clark replied opined shutdown DCPP.

Mr. through communicating those principles Committee Members has any Clark noted that none of the in a financial or other investment professional connection or Navy his own experience with U.S. PG&E or DCPP and noted that son is going to is "assume your reactors, where the philosophy in his considerations be aboard that ship," has guided plants. around commercial nuclear assessing life on, near and and closed her remarks by Ms. Magilhill thanked the Committee to maintain an openness beyond urging the Members of the DCISC backgrounds in nuclear their own professional and technical power. of that the current membership Mr. David Weisman observed he and technical backgrounds and the DCISC reflects science health and background in public queried how someone with a for appointment to the safety might receive consideration Committee. Dr. Rosin replied Diablo Canyon Independent Safety B. 9-39
that the appointing officials do take into serious consideration a nominee's concern for public health and safety in making their appointments to the DCISC and he noted that the Committee's founding principles require that it be competent to make an independent assessment of DCPP's safe operation and that technical understanding of how a nuclear power plant operates is essential to fulfilling the Committee's mandate from the CPUC. Ms. Sheila Baker was recognized and she queried whether plans for the proposed Yucca Mountain storage facility would affect the fuel storage situation at DCPP. PG&E Vice President Oatley replied that, in the event licensed storage facilities ever become available at Yucca Mountain, DCPP would have an option to transport fuel requiring storage to that facility in and by transportation facilities designed and approved for that purpose. Ms. Baker questioned whether rail or barge transportation might be utilized and Mr. Oatley replied that no methods of transporting the spent fuel have yet been considered, however, the proposed Holtec dry cask storage system does allow for flexibility of transport options in the future. He also noted that any option for off-site storage of DCPP spent fuel would be subject to first-in first-out priorities which would allow those nuclear power plants which have operated the longest, and consequently have the most spent fuel, to make first use of any new storage facility and that it could take some years before DCPP was eligible to send its spent fuel for off-site storage. Mr. Clark noted that any future method under consideration for adoption by DCPP, including the use of barges to transport the fuel, would necessarily be subject to a rigorous regulatory approval process including public hearings. There were no comments from any members of the public present in the audience following Mr. Dye's presentation concerning on-line maintenance activities (page 32 above) XXV ADJOURN MORNING MEETING The morning meeting of the Diablo Canyon Independent Safety Committee was adjourned by the Chair at 12:07 P.M.

Mr. Clark expressed the Committee's interest in reviewing the GVIT's report when it is available. 0 Management Expectations - Mr. Oatley noted that DCPP standards and managements' expectations are not being consistently met nor evaluated and reinforced. A focus area for the cultural work during 2001 will be to improve reinforcement of management expectations. Training sessions will be conducted for all supervisors to set and monitor expectations and to the train supervisors on dealing with conflict. In response to questions from Drs. Rossin and Cass, Mr. Oatley noted that Operations and Maintenance personnel have received extensive formal training in this area, however, effort will be made to make additional in-house provided training widespread throughout the DCPP organization. Vice President Oatley then reviewed and discussed with the Members some other areas which have experienced satisfactory levels of performance or improvement, but which PG&E management see as currently less significant than the key performance issues identified by the IAR. These areas will continue to be monitored, and include trending of low level errors, Emergency Response Organization drill and exercise performance, Maintenance training, high radiation area violations and pre-outage milestones. He identified some areas of positive performance including the CAP, Operations and Control Room formality, management communication to employees and external entities during California's energy crisis, interaction between the procurement groups and suppliers during PG&E's bankruptcy filing and DCPP housekeeping and overall material condition. Mr. Clark noted that the DCISC has expressed concern about the CAP's ability to effectively resolve problems in a timely manner, although, he also noted that all evaluators found the CAP effective in getting problems into its system and remarked the Committee would continue its interest in the CAP. Mr. Clark noted that human performance has been a focus area for improvement at DCPP for approximately ten years and that over that period the Committee has reviewed the many initiatives and efforts by PG&E to improve human performance at DCPP. He remarked that the Committee is interested in whether PG&E has involved all the necessary experts and resources to formulate and develop a plan to improve human B.9 -42

Members discussed the suggestion made earlier during the public meeting concerning members of the bargaining unit at DCPP making a presentation to the DCISC during a public meeting. The Chair noted that DCISC contact and interaction with DCPP line employees, including bargaining unit members, will continue during fact-finding. Dr. de Planque suggested the possibility of scheduling a presentation during a public meeting by a panel of representatives of the EAP, the ECP, Human Performance, and the Medical Center organizations. Dr. Rossin observed that the Committee should continue to focus on programs and that the Committee should not foster a perception by DCPP's employees that it functions in any way an alternative to the ECP. Members discussed with Vice President Oatley issues involved in inviting a working-level or first line leadership person from the DCPP bargaining unit to represent the BOBCATZ Program and to make a presentation to the Committee. Mr. Oatley promised to review these issues and to respond to the Committee. Dr. de Planque observed that it may be valuable to consider inviting a representative from the various safety oversight groups at DCPP, such as NSOC, PSRC, PNAC, to make a process-based presentation to the DCISC concerning their particular group's oversight functions. On a motion by Dr. Rossin, seconded by Dr. de Planque the Committee unanimously approved the draft of the Report of the March 14-16, 2001 fact-finding and authorized its transmittal to PG&E. On motion by Mr. Clark, seconded by Dr. Rossin, the Committee unanimously approved the draft of the Report of the May 14-16, 2001 fact-finding, subject to inclusion of minor editorial correction, and authorized its transmittal to PG&E. XXXI ADJOURNMENT OF THIRTY-THIRD SET OF MEETINGS Mr. Clark thanked Vice President Oatley and the PG&E presenters and personnel during these public sessions for their excellent presentations and responsiveness to the Committee. Drs. de Planque and Rossin expressed their thanks to Mr. Clark for his efforts as the Committee's Chair for the period July 1, 2000 through June 30, 2001. Mr. Clark expressed his good wishes to Dr. de Planque for her term as the next DCISC Chair. There being no further business, the thirty-third public meeting of the Diablo Canyon Independent Safety Committee was adjourned at 2:50 P.M. B.9-44

Units 1 and 2 Performance Indicators 2.2 provide a summary of PG&E's The following sections 2000 areas for the period of July performance in the subject through June 2001. 2.2.1 Capacity Factor have operated with a high The two units at Diablo Canyon The objective the industry average. capacity factor relative to an operating capacity factor was to have both units achieve of at least 96 (capacity factor between refueling outages) percent for both 2000 and 2001. was capacity factor for Unit 1 The 2000 year-end operating During this time, was 96.2 percent. 93.3 percent and for Unit 2 outage and was off-line Unit 1 went through its lR10 refueling including an unplanned outage for 40 days, 9 hours, 54 minutes, C-1
extension of 14.3 days due to main generator/exciter problems. The Unit 1 capacity factor through the end of 2000 also reflects an automatic reactor trip due to testing equipment problems on November 20, 2000. During the last half of 2000, Unit 1 experienced a minor curtailment to 83 percent to resolve a generator cooling water overheating problem and Unit 2 had a nine-day forced outage to repair extraction steam expansion bellows and condenser tube leaks. In addition, on December 22, 2000, both units experienced a precautionary curtailment to 23 percent due to high sea conditions. The operating capacity factors for Units 1 and 2 for the year through June 2001 are 100.3 percent and 97.7 percent respectively, with both Units expected to achieve the 96 percent objective performance as the units continue to operate through 2001. Both units were curtailed to 21 percent power for 1.7 days in January as a precautionary measure due to high ocean swells. During June 2001, Unit 1 experienced 2.3 days at reduced power to address unexpected contamination of the condensate storage tank and condenser hotwell water. Unit 2 continued its excellent performance in 2001, completing its record setting 2R10 Refueling Outage Power Ascension without problems. Unit 2 operated the remainder of June at full power. 2.2.2 Refueling Outages The Unit 1 tenth refueling outage (IR10) began on October 8, 2000 with a target duration of 26 days. The outage was completed in 40 days and 10 hours, with the majority of the overrun associated with emergent repairs on the main generator. Despite the extended duration, there were a number of accomplishments in 1R10. The total of four injuries (two recordable and two disabling) matched the previous best for an outage. Radiation dose of 158.1 person-rem was 20% lower than any previous Unit 1 outage. Human performance was very good, with only two significant events - an emergency safeguards feature actuation due to the simultaneous performance of two incompatible tests, and a wrong-component error that effected Unit 2 startup power. Schedule accomplishments included the shortest core off-loaded window (174 hours) , the earliest reactor head installation (19 days, 14 hours) , and the shortest window from head installation to Mode 4 (55 hours, without vacuum fill). Outage cost of $29.3 million was below the goal of $30M and was the lowest Unit 1 outage cost ever. As noted, the majority of the schedule delays were due to the main generator. On Day 18 of iR10, high potential testing of the stator identified a fault on phase C. Mobilization and repairs pushed availability of the secondary side approximately C-2

Leak testing B, which required another three days to lead seal in a radial after generator reassembly revealed a leak three days to repair. on the rotor that required an additional with the exciter voltage Another day was lost due to problems regulator panel during start up. The overrun was generally well up, reactor core testing managed, as the primary side was heated to await secondary side completed, and then returned to Mode 3 availability. evidenced by the Overall performance in IR10 was good as Throughout iR10 the organization as accomplishments noted above.

Inspections revealed that torque on the stator were as much as through bolts and building bolts on the 50% below the specified values. Tightening of the bolts required C-3
additional disassembly and reassembly of the generator end brackets, resulting in an extension of the generator schedule by about seven days and an impact of about four days to the overall schedule. In-place repair of scoring on the generator rotor shaft in the hydrogen seal area was also required. 2.2.3 Collective Radiation Dose The bulk of personnel radiation dose occurs during refueling outages. Therefore, the total annual dose is largely dependent upon the outage planning effectiveness, radiation levels, outage duration, and number of outages conducted in the year. The collective radiation dose goal for 2000 was 161 person rem total for both units. Included in that total was the Unit 1 tenth refueling outage goal of 150 person-rem. The actual dose during 1R10 was 162.3 person-rem. The total collective radiation dose for the year 2000 was 180.7 person-rem. The collective radiation dose goal for 2001 is 120 person rem for both units. The total dose through June 2001 is 114.1 person-rem, which includes 107.6 person-rem dose from the Unit 2 tenth refueling outage. The actual dose from 2R10 was 1.4 person-rem below the 109 person-rem projection, and represents a 10% reduction from DCPP's previous lowest value of 120.4 person rem in 2R9. 2.2.4 Industrial Safety Lost-Time Accident Rate The 2000 PG&E industrial safety goal was to have zero lost time injuries. The year-end total for 2000 was four lost time injuries. For 2001, the industrial safety goal is unchanged at zero lost-time injuries for the year. Two lost-time injuries have been recorded for 2001 through June. In response to the increase in lost-time injuries the following actions have been taken or are being implemented. Maintenance Services has adopted a "Behavior-Based Safety Program" where work is observed by peer evaluators and both safe and at-risk behavior is noted, with immediate feedback provided to the worker being observed so that behaviors can be corrected. A senior management safety observation program is being implemented where officers, managers, and key directors will be in the plant observing worker safety practices and behaviors. Observation results will be trended to evaluate effectiveness and determine further actions. C-4

During safety system actuations unplanned unplanned safety system period, there was one assessment the 2RI0 refueling actuation for Unit 2. On May 20, 2001, during bus Unit 2 experienced a failure of an electrical outage, positioned transfer test on vital 4kV Bus H due to an improperly circuit breaker.

Therefore, PG&E believes impurity levels. with the lowest practicable C-5
The index goal for 2001 is "less than or equal to 1.02", the same goal used for 2000. This index is based on a normalized ratio of the steam generator parameters divided by their limiting factors per INPO specifications where 1.00 is the lowest and most desirable score. The year-to-date average through the end of June 2001 is 1.00 for Unit 1, unchanged over the previous year, and 1.02 for Unit 2, a slight increase over the last year from 1.01. The increase in the Unit 2 index occurred in June 2001 primarily as a result of the temporarily increased feedwater iron concentrations that were expected following 2R10. The average index in Unit 2 is expected to decrease prior to the end of 2001. The minimum index reported is never less than 1.00 even though the actual number may be lower. Improvements in these indicators over the past several years can be attributed to continued emphasis on the optimization of the secondary chemistry program. Specifically, emphasis has been placed on control of parameters which impact feedwater iron concentration, the most challenging component of the index for Diablo Canyon, and on control of steam generator sodium. Chemistry continues to evaluate techniques to reduce feedwater iron concentrations; however, PG&E's business decision to continue using the full-flow condensate demineralizer to guard against a potential catastrophic saltwater leak into the condensate system (and resulting damage to the steam generators) limits the feedwater pH to reduce iron transport. To maintain low steam generator sodium concentrations, a goal of less than 3 gallons per day saltwater leakage into the main condenser was established in 2000. This is the main source of steam generator sodium. To date, this goal has been achieved in Unit 1 but leaks in Unit 2 main condenser continue to evade detection. 2.2.8 Fuel Reliability The purpose of the fuel reliability indicator is to monitor progress in achieving and maintaining high fuel integrity. Failed fuel represents a breach in the initial barrier for preventing offsite release of fission products. Such failure has a detrimental effect on operations and also increases the radiological hazards to plant workers. The PG&E goal for 2000 was to ensure that the "corrected" coolant radioactivity due to fuel failures did not exceed 5xi0-4 microcuries per gram ([tCi/g) of Iodine-131 in each unit. Unit 1 performance for this indicator for the second half of 2000 was 1x10-6 jtCi/g for every month. Unit 2 performance for this indicator for the second half of 2000 averaged 5.22xi0-4 4Ci/g, with a high monthly value of 6.34x10-4 pCi/g in July and a year-C-6
end value of 5.52xi0-4 ýtCi/g. Thus, only Unit 1 met the goal for all months of the second half of 2000. The value for The goal for 2001 remains at 5x10-4 ýICi/g.
ýtCi/g. The average Unit 1 through the end of June was 1x10-6 was 5.41x10-4 ViCi/g, value for Unit 2 through the end of June in June. Thus, only with a high monthly value of 1.12x10-3 ýtCi/g months of the first half of 2001.

These issues are generally resolved through mediation, intervention, referral, or another means acceptable to the employee. ECP documents these "Employee Contacts" along with their resolution. As of June 30, 2001 there have been 12 Employee Contacts. The ECP staffing has remained consistent with what was reported last year. Staffing includes two lead investigators with one supervising engineer. This staffing is considered appropriate. In December 2000, PG&E completed data collection for its most recent survey by SYNERGY of the culture of the DCPP organization. The results of the survey were finalized in March 2001. The results of the survey indicate notable improvement in both the safety culture and general culture and work environment. Although improvement has occurred in each of the following areas, site wide scores indicate opportunities for continued improvements in the areas of: "* Employee confidence in the Employee Concerns Program "* Employee confidence of the timeliness and effectiveness of the corrective action process "* Communication of basis and appropriateness of management's decision in areas involving cost, production or schedule versus nuclear safety Overall, the nuclear safety culture and the general culture

these areas is appropriate and if any of these are important enough to warrant further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee as well as those identified as a result of reviews of various safety related documents. 3.0 DISCUSSION 3.1 Corrective Action from September 22, 1999 Reactor Trip The DCISC reviewed the September 22, 1999 reactor trip at a fact-finding meeting in November 1999 (Reference 6.1) . The cause of the trip was a lightning strike in the 500 kV switchyard. Lightning struck the static ground wire protecting the Unit 1 500 kV tie line. This tripped the 500 kV overvoltage relay and opened the Unit 1 Power Circuit Breakers (PCBs) . The Unit 1 generators increased speed and lost synchronization with the PG&E system. The synchronization- check relays on the 12 kV buses prohibited fast transfer, as designed, causing the Reactor Coolant Pumps (RCPs) to slow. This resulted in RCS pressure increasing and the Power Operated Relief Valves (PORVs) opening, which in turn caused RCS pressure to decrease. The pressure decrease resulted in higher RCS temperature, and the reactor tripped on the over-temperature delta-T setpoint. Although the reactor trip was handled well by operators, there were some weaknesses noted: Operations and Chemistry were not aligned on planned condenser tube leak searches, more PA announcements were needed, there were some problems in securing the AFW pump, the four-hour emergency report to NRC was late, communication between the control room and 500 kV switchyard was less than optimal, and the Spent Fuel Pump was not noted to have tripped until regular rounds on the next shift. These were being addressed. Later, when attempting to restart the reactor, the reactor was manually tripped due to an inadvertent transfer from auxiliary power (backfeed) *o start-up power. The transfer resulted from switchyard operators not advising the Control Room when resetting the overvoltage trip relay, contrary to the requirements of restart policy. This was considered non cognitive personnel error on the part of the switchyard operator. D.1-2

3.2 Human Performance The DCISC met with Al Jorgensen, Director of the Human Performance (HP) Program, for an update on human performance results and initiatives. The Human Performance Group (HPG) is part of the Corrective Action Group which reports to Nuclear Quality Services. While human performance errors are inevitable, these events can be reduced by minimizing contributing factors and by applying corrective actions in order to prevent more significant occurrences in the future. The Human Performance Team analyzes low level ARs using the new analysis and culpability model, the Personnel Accountability Policy, which addresses accountability in relationship to HP events or issues. It is based on the accountability policy which Al Jorgensen wrote with Bill Blunt in 1996 as part of the EPRI program and was later adopted by INPO. Principles include blameless error (with corrective actions all the way up the line) and coaching, rather than discipline. The main points are as follows: "* A consistent accountability policy must be applied horizontally and vertically throughout the organization addressing all those directly and indirectly involved. Individuals can then learn from their errors. "* Definitions were given of the various terms used, such as accountable, consequences, human error, and positive discipline. "* The document covers responsibilities of managers, directors, and supervisors to provide positive recognition for employees and groups whose performance exemplifies accountability. "* Employees are responsible to report errors and assist in determining corrective actions. "* "Investigating Events and Determining Accountability" includes issues of intentionality. A Culpability Evaluation Tool is provided for the use of first line supervisors to help determine the level or severity of disciplinary actions in response to events or near misses caused by human error.

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate specific safety matters for the DCISC. The objective of the safety matter review was to determine if PG&E's performance in these areas is appropriate and if any of these areas revealed observations which are important enough to warrant further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee as well as those identified as a result of reviews of various safety related documents. The DCISC Team met with the DCPP Vice-President and Plant Manager, and with a number of managers of DCPP organizations and groups as described below. The primary purpose of these meetings was for new DCISC Member Dr. David Rossin to meet them, to acquaint him with the responsibilities and activities of each manager, to describe Dr. Rossin's particular areas of interest, and to understand a number of the plant's important issues and initiatives. 3.0 DISCUSSION 3.1 Observe Outage IR10 Daily Meeting The DCISC Fact-finding Team attended the 9:00 AM daily outage meeting for Outage IR10. This was the 1 7 th day of the outage. The meeting was run by the Outage Director, Brad Hinds. Overall progress to date was reported: the outage was approximately $788,000 over budget and about two days behind schedule. Radiation exposure to date was 104.3 person-Rem, compared to an estimated 119.9 person-Rem. There had been two recordable injuries to date, neither of which was rated as serious. There had been three reportable events in contrast to the Outage Safety Plan goal of zero. These are described below in Section 3.3. The schedule for the remaining outage activities was distributed and reviewed. Each function at the plant was represented, and the respective leaders reported on current status, progress and/or problems. This included the following:

Hinds reported that DCPP management emphasized "safety first" with respect to personnel and nuclear safety. There had been two minor personnel injuries to-date. Radiation protection efforts had been successful in that the Steam Generator bowl doses were the lowest since Outage 1R1, primarily due to a joint effort by Chemistry and Operations to chemically decontaminate the Reactor Coolant System (RCS) early in the shutdown. This is in sharp contrast to Outage 1R9 where dose rates were substantially higher than normal, some of which was due to radiation from this area. The Outage Safety Plan was reviewed. The DCISC has reviewed the Plan in the past and found it to be a good tool for safety awareness and guidance for maintaining plant safety status in conjunction with the defense-in-depth approach to nuclear safety. The Plan summarized the outage scope and goals and consisted of the following safety attributes:
"* Decay heat removal under various RCS configurations and contingency plans "* RCS inventory control and contingency plans "* Reactivity control and contingency plans "* Electrical power sources and contingency plans "* Spent fuel cooling and contingency plans "* Containment closure "* Containment fan cooler and Component Cooling Water (CCW) requirements "* High risk evolutions and associated contingency plans "* Infrequently performed tests or evolutions The Plan appeared comprehensive and on-target. In the outage coordination room there was a useful chart on the wall showing Reactor Vessel and Cavity water level and heat removal modes during various plant states and operational activities. The Team believes this chart helps keep personnel aware of the conditions that apply during each mode.
Concerning nuclear safety, one goal was to have no reportable events; however, there had already been the following three reportable events:
- A CCW pump started (as designed) due to a breaker misalignment D.2-4

"* An Emergency loss of start-up power started (as designed) upon a due to work on the wrong unit when a relay "* An Auxiliary Salt Water pump tripped failed to reset during testing items in a future meeting.

3.5 Meeting with NRC Resident Inspector The DCISC Team met with David Proulx, NRC Resident Inspector. The primary purpose of the meeting was for new DCISC Member David Rossin to meet Mr. Proulx, describe the activities and plans of the DCISC, and hear about NRC's activities at DCPP. Mr. Proulx indicated that the NRC was looking particularly at human performance, effects of deregulation (especially transmission grid reliability), and its new Revised Reactor Oversight Program (RROP) . The last item was a major change for the NRC, and the plant resident inspectors were still learning how to use the risk-based approach. 3.6 Meeting with Vice-President and Plant Manager The DCISC Team met with Vice-President and Plant Manager, Dave Oatley. Human performance was an item that was receiving attention at all levels in the plant. Mr. Oatley reported that management was rolling out three-way communication, self verification and similar techniques in the Maintenance and Engineering areas because the techniques had been successful in Operations. Improved techniques and behaviors were also being emphasized. A new Human Performance Steering Committee has been formed. Regarding the current 1R10 refueling outage, Mr. Oatley was pleased with progress to-date and particularly with ALARA efforts and results. He stated they were also working on better radiation release communications with the public. 3.7 Meeting with Manager of Engineering Services The DCISC Fact-finding Team met with Dave Miklush, Manager of Engineering Services. Mr. Miklush described the engineering transition in which the engineering function moved from PG&E Headquarters in San Francisco to the plant. He also described the System Engineer Program. For Outage IR10, Engineering had formed local leak rate testing teams with Operations, which had been effective. The number of Engineering Fixit Teams had been doubled for the outage. Engineering had hired ten recent graduate engineers who were going through a structured training and familiarization process. The average age of employees (now about 47) was D.2-6

3.10 Tour of Containment Messrs. Rossin and Wardell performed a tour of the Unit 1 Containment accompanied by Stan Ketelsen and Ken Bych, who was acting as Containment Coordinator during the outage. The group observed fuel movement, installation of the new sump debris racks, radiation protection activities, and other miscellaneous activities. Fuel movement and placement in the core was videotaped and independently verified by a reactor engineer. The refueling equipment appeared to work well. Also observed were the major reactor coolant system components such as reactor vessel, reactor coolant pumps, piping, steam generators, and pressurizer. Radiation protection practices inside containment appeared appropriate, although there seemed to be more personnel in containment than necessary. Upon exiting the containment, the group was effectively processed by Radiation Protection personnel. The DCPP personnel dosimetry equipment and procedures appeared satisfactory. Containment air lock procedures were properly followed in that only one of the two air lock doors was open at a time.
== Conclusion:== Activities inside Containment during Outage iRl0 appeared to be properly controlled. Radiation protection appeared effective with knowledgeable and helpful RP personnel conveniently stationed in safe work areas. 3.11 Observe Control Room Shift Manager Turnover The DCISC Team observed the afternoon turnover between David Bahner (departing day shift manager) and Rich Luckett (oncoming night shift manager). The two managers used the Shift Manager Turnover Report (Attachment 1), which included all major conditions and activities for both units. It was noted that the first winter storm of the year was approaching with moderate ocean swells and kelp. The managers also used a Technical Specification Summary Sheet which listed component or train non-availability, compensatory actions and alternate line-ups. The managers performed a walkdown of the Units 1 and 2 control boards to ascertain and agree on the status of systems and components. The Shift Foremen were separately performing the same turnover and control board walkdown. The DCISC Team also observed a Shift Brief for the departing and on-coming shifts for the Unit 1 outage. The on-coming D.2-8

The plant has about 18 years' storage space on-site. 3.14 Reactor Pressure Vessel Integrity The Fact-finding Team met with Brian Lo Conte, who has responsibility for this issue. (Dr. Rossin had requested a briefing on the Diablo Canyon Plant status as a result of his long-term interest in pressure vessel embrittlement and his early research on Effective Compliance Lifetime calculations.) Mr. Lo Conte provided documentation on Technical Specification (TS) 5.6.6, the licensing requirement governing vessel lifetime. Extended exposure to neutrons changes the toughness of steel, raising strength but increasing the brittleness of the material. Steel exhibits a rise in the temperature at which its toughness properties change from "brittle" at low temperature to tough or ductile above this transition temperature. The TS requires that vessel steel remain in its tough condition at pressure, not only for operation but for pressure testing and early pressurization at startup when the vessel has not yet reached full operating temperature. Another limiting condition applies to a safety-related hypothetical event in which the maximum injection of emergency coolant takes place. These requirements have been developed following years of research, review and negotiations, and are now in use throughout the regulated industry. They are believed to be highly conservative, but significant uncertainties still exist in material behavior, neutron dosimetry, variation of material condition throughout the vessel wall, mechanical testing and fracture mechanics, coolant injection rates and temperature effects, and the low probability of the limiting event. For most reactors and most license extension applications, calculations are likely to show that the vessels will remain in compliance. More data will be obtained as surveillance capsules containing specimens that can be tested to measure toughness with a number of years of lead-time become available. DCPP has its own surveillance capsules in place in the vessel, and the first two (Unit 1) and three (Unit 2) have already been removed and tested. DCPP also has some EPRI research capsules installed for irradiation. D.2-10

NQS identified the discrepancies as a Quality Problem in an Action Request. Suggested actions were the following:
"* Establish and reaffirm management's expectations "* Revise applicable procedures to reflect management's expectations and the current plant organization "* Convene the Aging Management Working Group "* Other identified actions A completion date of July 22, 2000 was initially established; however, this was revised to September 12. The procedure (Reference 6.4) was revised in August to accomplish the following: "* Updated organizational structure and titles consistent with the present organization. "* Changed responsibility for Aging Management from Regulatory and Design Services to Engineering Services. "* Changed full-time Aging Management Program Manager to part-time Aging Management Program Coordinator (AMPC). "* Eliminated the Plant Aging Management Working Group (the AMPC will call in resources as needed). "* Revised the requirement from an annual to a periodic assessment report.
In addition to the above procedure changes, the following management expectations and actions were identified:
"* Continue to rely on and develop the System Long Term Plan process. The cognizant System Engineer has the responsibility for taking the lead in each area. "* Consider undertaking an effort to identify "gaps" in the maintenance program for age-related failures (e.g., equipment failures, such as expansion joint, bus bar, and control board lamp socket failures) of components not previously included in the Aging Management Program. (This is similar to DCISC Recommendation R00-6 (Reference 6.3)). "* Involve the Asset Teams to provide feedback on equipment condition.

Dr. Rossin and Mr. Hite discussed their philosophies regarding radiation protection and ALARA programs and organizations. Mr. Hite plans to make changes in the RP program and organization at DCPP similar to those he had implemented at Duane Arnold which he considered successful.
== Conclusion:== The new Radiation Protection Director appeared knowledgeable and experienced. It is recommended that the DCISC closely follow the upcoming changes in management, organization and progress in Radiation Protection. 3.17 Meeting with Human Resources Director The DCISC Team met with Linda Jolley, Human Resources Director. Ms. Jolley described the Culture Transition Initiative, which was developed following concerns identified by the Synergy Safety Culture Survey. The Initiative is being taken to improve trust in management and create an improved safety conscious workforce. The Initiative is based on developing the five following behaviors:
- 1. Understand others
- 2. Embrace feedback
- 3. Provide face time
- 4. Develop and support common goals
- 5. Create a positive work environment Ms. Jolley described the series of training sessions which have taken place with top management, middle management and employees. She also described the bi-monthly meetings held with supervisory levels at the plant and the 360-degree personnel performance feedback process for each manager/supervisor. The DCISC has been following this initiative since its inception.

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate specific safety matters for the DCISC. The objective of the safety matter review was to determine if PG&E's performance in these areas is appropriate and if any of these are important enough to warrant further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee as well as those identified as a result of reviews of various safety related documents. D. 3-1
3.0 DISCUSSION 3.1 Joint PNAC/NSOC Meeting The DCPP President's Nuclear Advisory Committee (PNAC) and the Nuclear Safety Oversight Committee (NSOC) held one of its regular scheduled meetings on November 14, 2000 at DCPP. A. D. Rossin and J. Booker attended on behalf of the DCISC as observers. The agenda is included as Attachment 1. Attendees were: PNAC & NSOC Members: PG&E members L. Womack, J. Becker, B. Crockett, D. Oatley, J. Tomkins, G. Rueger, G. Smith, and M. Hughes and external members M. Blevins, J. Martin and C. Warren. Other attendees with PG&E were: P. Nugent, D. Miklush, B. Terrell, J. Hodges, D. Spaulding, D. Taggart and D. Locke. The following items were discussed:
- 1. License Amendment Requests (LAR): Two LARs were presented and approved by NSOC: 1) Accumulator Limits Clarification and 2) TS Bases Control Program.
- 2. System Engineering Program and Management Expectations of System Engineers: A summary of the roles and responsibilities of system engineers was presented. The roles and responsibilities include:
- Operations and Asset Team Support
- System engineering interface functions
- System engineering qualification and training
- System performance monitoring
- Design and license basis knowledge and maintenance
- Maintenance rule program functions
- System long term planning Several functions have been added to the responsibilities of the system engineers. These include development of long-term plans and maintenance of the design basis of the system. The system engineer is also responsible to be cognizant of the PM program and basis for their system.
One of the External Members asked if DCPP was planning on resurrecting the system health reports. PG&E responded that System Engineering felt that it was importanr that the long-D.3-2
term planning process be firmly established prior to developing new system health reports. The status of the ability of the system engineers to perform their seven functions will be discussed at a future meeting. The responsibility of the system engineers in evaluating industry-operating experience was also discussed. PG&E said that they were also looking at Preventive Maintenance (PM) on passive/static systems (such as bus failures and leaking bellows) to prevent forced outages.
- 3. Subcommittee Reports:
A. Plant status and performance indicators: Site capacity factor for both units is in excess of 91%. The industry personnel safety accident rate is currently 0.28 per 200,000 hours of work. Recordable injuries are at the goal of less than or equal to 10 per year. Radiation exposure for 2000 is expected to be lowest for Unit 1 ever. The current average number of event-free days is 30 days, which meets the goal. However, the trend is not in a favorable direction. Two human performance errors were discussed: 1) working on the wrong fan and 2) loss of start-up power to Unit 2. The loss of start-up power to Unit 2 was due to operation of an incorrect switch. The Unit 1 start-up transformer was intended to be cleared but the Unit 2 transformer was cleared instead. One unplanned automatic reactor trip had occurred through the end of October. The Unit 1 refueling outage was also discussed. B. PSRC Summary: A summary of issues discussed at the PSRC meetings were reviewed. These issues include: "* NCR N0002109 - related to plant monitoring equipment "* NCR N0002114 - related to the lubrication program "* Changes to the emergency plan to relocate the OSC and assembly areas "* Operability of the 230 kV system during rolling blackouts on 6/14/00 "* Revision of the P-9 setpoint and procedures to accommodate kelp attack coping strategies "* Deletion of commitment to only use EDG 7 day AOT for unplanned maintenance D.3-3
"* NCR N0002115 related to the licensing basis for the containment isolation valves "* Installation of scaffolding around recirc sump for installation of temporary shielding C. LER and NOV summary: A summary of four recent licensee event reports (LERs) that were submitted to the NRC was reviewed. Eleven LERs have been submitted to date, and four additional LERs will be submitted prior to the end of the year concerning events that occurred during the outage. Three NCVs that were issued during the last period were also reviewed. The trend of NCVs at DCPP is comparable to the average number received at other Region IV plants. One of the External Members pointed out that NCVs are no longer the best measure of performance and that management needs to be sensitive to monitoring problem trends at the plant. D. LBIE Assessment: Twenty LBIE reviews were completed during the assessment period. There were no significant issues identified related to LBIEs. However, a QE was issued regarding implementation of an LBIE related to installation of scaffolding around the RHR sump. DCPP originally had 600 employees qualified to do LBIEs. They have reduced the number to approximately 300 and will probably reduce down to about 150. They feel that they produce better LBIEs with fewer better-trained employees. E. NCR and NQS interest items: The three NCRs that were initiated during this period were discussed. The External Members felt two of the NCRs were weak, and that additional action is warranted to improve the NCRs and the root cause analyses. Additionally, they felt that the number of NCRs generated is low for a good performing plant. They recommended that DCPP perform benchmarking of other plants and a self assessment also be performed. PG&E staff indicated that they have been participating in an NEI task force on root cause and have identified many improvements to the process to be implemented over the next year. PG&E agreed to review the improvements with NSOC at the next NSOC meeting. NQS reviewed the projected 2001 audit schedule for DCPP. In response to a question, they stated that the audit plan is integrated with self-assessment plans and that they will provide the integrated schedule to NSOC. They also stated that D.3-4

- ERO drill/exercise performance indicator
- Maintenance training weakness
- 6. Strategy to Address Human Performance Issues: The human performance program is being revised to add more formality. The new program is based on the formation of a human performance steering committee. The purpose of the steering committee is to develop a common philosophy and strategy to address human performance improvement and champion human performance at DCPP. The committee currently meets monthly and reviews leading and lagging human performance rate indicators, human performance related issues from self assessments, industrial safety, human performance review committee meeting minutes, status of human performance related long-term strategic plans, and emerging issues.
Human performance fundamentals training is being scheduled for all Operations, Maintenance, and Engineering personnel. The initial course will be completed by the end of 2001. Continuing training will include refresher training on the subject. Human performance errors related to the clearance process have been decreasing over the last few outages. Six errors occurred in IR10 as opposed to eight in IR9 and seven in 2R9. However, the overall error rate in Operations indicates a trend in declining performance.
- 7. RP and ALARA Program Strategies: The purpose of this presentation was to present an overview of current RP and ALARA programs, and future direction and strategies. Both units are in the middle of the third quartile for RP performance in the industry. Although neither unit has ever had less than 100 person-rem per outage, 1R10 was the lowest Unit 1 collective dose outage. Much of the reduced dose was due to good shutdown chemistry control and zinc injection over the last two years. The Director of RP indicated that traditional thinking is that a lot of money must be spent to reduce dose. However, he indicated it should be able to be done by focusing on planning, scheduling and aligning RP with maintenance and operations processes and in-field workers.
Several recent audits and inspections have been conducted. The feedback is being consolidated to identify and correct programmatic issues. Specific improvements will include: D.3-6
- Better RWP format
- Better define roles and responsibilities including hot
- Review current controls for improvements tracking and particle zone coverage, multi-badging, dose prepare for a trending, and technology improvements to reduced number of available contract technicians performer.

The intake structure concrete during 1R10 D.3-7
delaminations has been reviewed at many Fact Findings, Public Meetings, and plant tours and has also been reported in DCISC annual reports. Diablo Canyon's Intake Structure/Circulating Water Conduits (CWC) surveillance program, initiated in 1991 for Units 1 and 2, monitors, restores and preserves the structural integrity of the reinforced concrete structures in accordance with plant procedure TSl.ID4 (Reference 6.1). The inspections provide data for trending the degradation of the structures as well as providing data on the concrete condition, assessing corrosive degradation and furnishing engineering properties of the concrete to assist in the development of future inspection criteria and repair priorities. The surveillance program is directed by ES Civil Engineering and performed by Technical and Ecological Services. Non-submerged areas of the structures are inspected annually and submerged areas (dewatered during refueling outages) are inspected once per fuel cycle based on a sampling program. As a result of an aggressive surveillance and repair program, the quantity of the delaminations and degraded concrete at the intake structure and CWCs have decreased significantly since the inception of the programs in 1991. The surveillance and repair programs have effectively controlled the effects of the harsh coastal environment and allowed the structures to perform their intended functions. The structures are currently in good condition and are classified as (a) (2) status under the Maintenance Rule Program. The results of the 1R10 surveillance and repairs are summarized below: Circulating Water Conduit (CWC) - The Unit 1 & 2 CWCs have been retrofitted with a sacrificial cathodic protection (CP) system (installed in Unit 1 -9/95 & Unit 2 - 4/96) . As a result, corrosion of the embedded reinforcement has been arrested. No concrete repairs were performed during 1R10. Critical elements of the structure have been repaired in previous outages. Intake Structure submerged areas (i.e. CWC forebays, ASW forebays, traveling screen forebays) - The majority of the degraded concrete has been repaired in the submerged areas with the exception of the traveling forebays and the bar rack bays. Though the investigation has shown that the degradation in these areas does not currently jeopardize the building structural integrity, measures to repair and or arrest the steel corrosion have begun. Specifically, an impressed current D.3-8
CP system was installed in traveling screen forebay 1-i during IRl0. This system is designed to prevent further steel reinforcement corrosion. If this newly installed CP system performs as designed, it will be applied to the remaining forebays. Intake Structure non-submerged areas (i.e. topdeck, pump deck, ASW vaults, seawall) - The repair and surveillance program has reduced the total amount of degraded concrete by 60% in the non-submerged areas. The majority of the areas that have structural significance have been repaired. The remaining required repairs are planned to be repaired during 2R10.
== Conclusion:== The overall condition of the intake structure and the CWCs is classified as good. It appears that the aggressive surveillance and repair program implemented by DCPP has ensured that the design basis is maintained. 3.3 Outage IR10 RP Results Bob Hite, Director Radiation Protection (RP), presented a summary of performance of the Radiation Protection Dept. during 1R10. A lot of attention was paid to ALARA. Hite explained that ALARA is a useful planning tool, and that better planned outage work leads to lower costs and better attention to detail. At the NSOC meeting on 11/14/00, an NSOC member noted that Diablo Canyon has been in the middle of the third quartile for nuclear plant ALARA performance, and that this outage will not change that. Hite discussed the radiation exposure goals that had been set for 18 projects during IR10. Exposures exceeded the goals in 10 projects. The "goals" were really more like "stretch performance objectives" based on work that would be carried out as planned. These plans did not include additional radiation allowances for contingency. The results and the planning are OK, however the numbers require explanation. One radiation issue stemming from operations that was noted was the number of radiation contaminations. Most of these should be avoidable. Some are actually built into the way things are done. Contaminations are costly, and they do affect the morale of plant workers. Bob Hite discussed examples where their observations have identified potential improvements. One example involves the shoe covers that are use at Diablo Canyon. There are new designs that are easier to wear and avoid some repeating contamination problems. Whether new D.3-9
clothing can be obtained in time for the upcoming 2R10 is not clear yet. There are a number of areas in which Radiation Protection needs to take the lead in identifying and implementing changes. Audit teams are unlikely to identify any of these problem areas. There will be some costs, but the savings may well be worth it. Radiation Protection needs management support to make these changes take place. The August 2000, audit of Radiation Protection Performance was a very complete and detailed audit. The audit reported that the health of the program is good, and rated almost all areas as satisfactory. A number of items were identified for improvement. Most of these involve documentation or adherence to commitments for numbers of inspections, etc. The findings should all be attended to and closed out. PG&E reviewed the July 2000 reports for Radiation Protection and for Chemical & Environmental Operations. These involved Performance Plan Indicators. These should be evaluated critically to determine which indicators have real meaning and which should be related to performance measures. Indicators that require frequent explanations to interpret the meaning of results are probably not simple enough or meaningful enough to use for this purpose.
== Conclusion:== PG&E was able to reduce the dose during IR10 such that IRl0 was the lowest of any Unit 1 refueling outages. PG&E also believes that DCPP needs to focus on being a top industry performer in this area and that planning and scheduling of work needs to be improved. DCISC will continue to follow this area. 3.4 Corrective actions on 9/22/99 Unit 1 reactor trip. This item was discussed at the November 18 & 19, 1999 fact finding meeting (Reference 6.2) . The cause of Unit 1 reactor trip on 9/22/99 was lightning that struck the static ground wire protecting the Unit 1 500 kV tie line from the plant to the 500 kV switchyard. This tripped the 500 kV overvoltage relay and opened the Unit 1 Power Circuit Breakers, which then led to the reactor trip. The purpose of this discussion was to review the PG&E actions to prevent further trips like this. PG&E has investigated the D.3-10

One will which prevent future relay action such of the be to install a time delay on the instantaneous portion will be installed trip circuit.

When completed, the changes should prevent similar relay action. 3.5 V.C.

This occurred. The crack is at the pipe-to-nozzle and during the welding, particular joint was field-welded, D.3-11
inspection revealed improper bonding. A large part of the weld had to be chipped out and replaced. It is likely that the techniques used for positioning the pipe during this process resulted in residual stresses and perhaps other weld integrity problems. The other issue is that primary coolant leakage had been occurring over an extended period of t:me and had not been discovered. Hot water evaporated in the air boot leaving crystalline material that was not found until visual inspection during a refueling outage. No leak detection system had provided any indications of leakage. Root cause analyses have not yet been completed. NRC has issued notice 2000-17 (Reference 6.3), but has not called for any actions by licensees. During the 1R10 outage, an experienced staff engineer from the In-Service Inspection group crawled through the manway around the reactor vessel and visually examined primary piping to nozzle weld joint regions. No indications of cracking or leakage were found. Mr. Gonzales and Mr. Portney provided an excellent explanation of the event and the information that had been obtained to date. Updates should be scheduled at future fact finding meetings.
== Conclusion:== PG&E is taking action to keep informed of the primary coolant piping cracks and investigation at V.C. Summer. They have also performed visual inspection around the reactor vessel of the primary piping to nozzle weld joint regions. 3.6 SG Inspection Results PG&E reported on the inspection and plugging of steam generator (SG) during 1R10. The SG inspections and results have been reviewed at many fact finding meetings and DCISC Public Meetings. Including tubes plugged and unplugged during this inspection, they had a net of 65 tubes or 0.5% plugged in all four SGs. This is not as many as they have plugged in 1R7 (117 tubes) and 1R8 (199 tubes). They currently have a total 526 tubes plugged in all four SG which is 3.9%. The license limit is 15% of total for all SGs or any one SG. PG&E feels that when they reach 10% plugged for all SGs, they will get to where all turbine valves will be wide open and will impact MW D.3-12

When they get start sleeving the tubes. the tubes plugged in SG 1-1, Through 1R9 there were 3.5% of and 1.4% in SG 1-4 for a total 8.1% in SG 1-2, 0.7% in SG 1-2 have to do any of 3.4%. PG&E thinks that they will not sleeving for about 10 years. tube plugging does not have any

== Conclusion:== It appears that PG&E is taking appropriate action to design and license on-site spent fuel storage facilities in a timely manner to accommodate all plant generated spent fuel. They are also informing the Government Officials and the Public in a timely manner. 3.8 Nuclear Fuel Items The following nuclear fuel related items have been reviewed at prior fact finding meetings and presented at Public Meetings. The purpose of these discussions was to review the status of these items. 1R10 Nuclear Fuel Performance/Inspection DCPP did not have any leaking fuel during the past cycle and did not find any during the inspection. DCPP has never had any leaking fuel in Unit 1. They did find a large number of failures of the top nozzle spring screws with the twice-burned fuel assemblies. The screws are breaking, but they did not have any loose parts. Westinghouse identified this problem after 1R9 at other plants and DCPP found this problem in 2R9 and IR10. Fuel inspections conducted during lRl0 showed fewer top nozzle spring screw failures than 2R9 inspections. DCPP prepared an Operability Evaluation (Reference 6.4) to document the operability of Units 1 & 2 utilizing Westinghouse fuel assemblies with potentiality fractured top nozzle spring screws. The evaluation demonstrated that plant operation utilizing fuel assemblies with fractured top nozzle hold down spring screws will not have an adverse effect on the integrity of the components of the reactor coolant system or connecting systems. The fix is to go to a different type of material for the screws. DCPP will go to a new design for fuel to be installed during 1RI1 and 2R11, but may still have problem through cycle 1R12 and 2R12.
== Conclusion:== PG&E appears to be taking appropriate actions dealing with the top nozzle spring screw failure and has prepared an Operability Evaluation addressing the issue. D. 3-14

4.0 CONCLUSION
S 4.1 Overall, the PNAC/NSOC meeting was well-planned, well organized and attended, and PNAC/NSOC appears to have fulfilled their required duties. There was an exchange of observations, opinions, and suggestions at the PNAC/NSOC meeting and good participation by the outside Members. It also appears to be very beneficial to have the joint PNAC/NSOC meetings, since each committee covers much of the same agenda. DCISC should continue to monitor the PNAC and NSOC meetings to observe their review of plant safety issues. 4.2 The overall condition of the intake structure and the CWCs is classified as good.

4.6 It appears that SG tube plugging does not any impact on the safety or generation of the plant at this time and should not have any impact for approximately 10 years. It is recommended that DCISC continue to review SG tube inspections and results after each refueling outage. 4.7 It appears that PG&E is taking appropriate action to design and license on-site spent fuel storage facilities in a timely manner to accommodate all plant generated spent fuel. They are also informing the Government Officials and the Public in a timely manner. 4.8 PG&E appears to be taking appropriate actions dealing with the top nozzle spring screw failure and has prepared an Operability Evaluation addressing the issue. 4.9 PG&E appears to be taking appropriate actions to deal with the fuel pellet gap re-opening problems and has resolved the issue on Unit 1. This issue should be resolved in Unit 2 when a new fuel design in installed in 2R10. The DCISC should review the status of gap re-opening in 2001 when Westinghouse has resolved the issue. 4.10 The DCISC should review fuel cycle length again in late 2001 if PG&E has changed their plans. 5.0 RECOMMENDATIONS There are no recommendations for PG&E in this report.

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate specific safety matters for the DCISC, focusing on Human Performance. The objective of the safety matter review was to determine if PG&E's performance in this area is appropriate and if any specific aspect warrants further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee as well as those identified as a result of reviews of various safety related documents. 3.0 DISCUSSION 3.1 Review of PGE's response to DCISC annual report, July 1 July 30, 2000 There was a review and clarification of issues covered in PG&E's response to DCISC annual report, to be completed at the February 7-8, 2001 Public Meeting. 3.2 Management View of Human Performance (HP) The HP coordinator presented an overview of the Human Performance (HP) program. This subject was previously reviewed by the DCISC in the July 6, 2000 fact-finding; July 2000 annual report; and July 1999 annual report (References 6.1 and 6.2). HP has grown to have the full support of plant management, with a steering committee of senior managers, and working committees representing the various departments - Operations, Engineering, Work Control, and Maintenance. Until error rates stabilize and decline, the steering committee will continue to meet monthly to review plant HP and systems for error prevention The purpose of the Human Performance Steering Committee (HPSC) HPSC is to review and analyze performance data collected from various Committees, performance indicators, and events to ensure actions are taken with a focus on good human performance behaviors (Reference 6.3). Recent trainings included:
- A 2 -day INPO training for all managers, directors, and asset team leaders in September 2000 D.4-2
"* A 5-hour HP course for Maintenance service craft "* Operations HP training as part of their requalification program. The purpose of the training was to: "* Generate understanding of HP terminology, and to have it be consistent and uniform throughout the plant "* Help see precursors to errors "* Analyze risk factors and anticipate errors "* Facilitate dialogue for good tail board discussions "* Provide a tool for Operations and Maintenance in observation performance in the field "* Teach the 3 key behaviors: effective tailboards, 3-way communication, and self- verification. Error rate - there have been some recent innovations, as follows: "* During the last outage, the first page of the POD (Plan of the Day) focused on safety and HP, stating "we want you to do it right the first time." "* HP is defining errors more precisely than in the past. "* The HP course emphasizes organizational as well as individual responsibility for errors. "* HP does its own evaluation, and determines which organization is responsible. "* "Event-free days" is being used as another indicator of HP. Error rate is measured per 10,000 work-hours, in 90-day increments. While there is a downward trend since the October outage, continuing through January, there was an increase in error rate in 2000, especially during outages, This last may be due to a number of factors: "* There is increased opportunity for errors, with more activity per hour per person (2.5-3 times normal) "* Activity is less routine i.e. with more novelty than usual "* Less predictability than during on-line time. "* Committee member inquired regarding errors by employees vs contractors. A review of this done a few outages ago indicated there was no difference between the two groups. NPG'S error rate goal has been reduced by 25%, to not exceed 12 events per year. Significant events were by down by half, D.4-3
particularly since the previous outage. A report on outage errors will be made available to the Committee.
Conclusion:
The plant-wide Human Performance Programs have gained the full support of management. Although error rate appears to have increased, recent plans to reduce it seem promising. DCISC follow-up should include attention to maintenance issues as described in next section. 3.3 Maintenance Human Performance Problem: of the increasing error rate trend, 40-50% occurred in Maintenance. To remedy this, an improved Management Observation Program (MOP) was introduced in August, 2000, with less focus on results, and more on behavior that can lead to errors. A significant error occurred in August when a motor was removed from the wrong ventilation fan. Since personnel were working on uncleared equipment, the fan could have started at any time during the procedure with risk of serious injury. Causal factors contributing to this incident (and similar ones) revealed the following: "* Poor communication, with lack of attention both to tailboards and to the STAR self-verification system "* "Social loafing," defined as a tendency during team-based activities to follow others rather than taking individual responsibility to clarify details. "* The workers have distracting issues, such as steam plant divestiture and the STARS initiative. These tend to increase both distrust of management, and job insecurity. "* Aging of workers: While still able to perform their job adequately, specific aging-related issues affect their performance and safety. Factors include declining reaction time and fitness, plus weight gain, which increase injury proneness, compounded by a longer recovery time. Solutions:
- A plant-wide HP program steering committee was created, with department sub-committees. In a critique for the year 2000, the department concluded that it has made progress, with more cooperation among the upper levels (managers, D.4-4
supervisors, directors) but that it had not yet trickled down to craft. "* An objective for 2001 is that HP enroll the bargaining unit leadership and integrate craft into the "we culture." The People/Performance Center of Excellence will take over this function. "* Craft leadership attended a newly developed training plus INPO training, which will then given to the online workers. "* Encourage use of 3-way communication, self-verification, and good tailboards. "* Re tailboards: They have been inconsistent in addressing personnel safety issues, with some tailboards not mentioning safety at all. The recommendation is that all departments continue to use the tailboard checklist that has already been developed, which includes safety issues, being very specific about potential hazards with every job. "* Culpability policy: Accountability is both individual and organization-based. Rather than "blameless error", each individual is responsible and accountable, with a continuum of responsibility. There is a corresponding escalation of positive discipline, beginning with a coaching and counseling discussion with the supervisor. An incident is documented, then remains in the record for 6 months. In certain instances, individuals may be asked to take a day off "to think about the situation."
== Conclusion:== It appears that PG&E is adequately addressing the issue of increased error rate in Maintenance. The DCISC should follow up on the following questions regarding error rate in Maintenance: "* Could the increase in error rate during outages also reflect increased overtime? "* Are there figures to correlate the two factors? "* What is the comparative error rate of employees vs contractors? One recent review of this issue indicated that there was no difference. "* Is PG&E addressing issues of maintenance worker fitness? The DCISC should request specific data regarding outage error rate of employees versus contractors. D.4-5
3.4 Human Performance Measures for Engineering (Latent Errors) There is a separate Engineering HP Committee, with 10 sub-process owners. It meets twice a year and reports on performance including evaluating event trend records (ETR's). Engineering has a built-in self-verification program, but still is in need of a specific HP training process, since the INPO course has been geared to Operations and Maintenance. To address this industry-wide issue, Palo Verde was about to host a one-day meeting, with 15-20 participating plants. The following issues reflect the need to address error prevention in engineering: "* A problem with misplaced diodes involved electrical drawings that were transferred from the other unit without checking specific differences. "* A forced outage in May while testing the RHR system was due to an incorrect adjustment. "* Design issues and ergonomics in the control room have not been addressed since 1988. While no specific errors can be attributed to this, innovations in this area would be helpful. Some remedial measures have already been taken such as: "* The STAR simulator, used to test and train the timed individual response in emergency situations, was used by engineers who write surveillance tests, in order to see how human factors affect performance. "* A higher level of coordination among engineering, operations, and vendors, required for optimal results, is demonstrated in the following. Engineering built an inverter panel with indicator lights, and asked Operations, who owns labeling, for design input. They also requested a mock-up of the new digital feed pump controls from the vendor before approving it.
== Conclusion:== Engineering appears to be addressing its HP issues appropriately. The DCISC should have a fact-finding meeting that address issues of control room design and ergonomics. D.4-6
3.5 Informal Meeting With Supervisors to Discuss HP Issues An informal meeting was held with 16 supervisors from various departments including Engineering, NQS, Chemistry, Radiation Protection, Operations, Security, and Maintenance. The following topics were discussed; Chemistry/environmuental has been downsized, with a resulting increase in individual work load, and less outside help than before. This leads to some resistance to HP as "just another thing to do." Safety group: "* Due to efforts of engineering and maintenance, AR's are now handled on average within 130 days, as opposed to the previous average of 600 days. "* Documented ETRs (event trend records), trended accurately by code, increased from 30% to 75%. Seven self- assessments were done in engineering in 2000, and then used to identify processes to observe next year. Maintenance: "* The move to a team structure initially created fear of increased lay-offs. These fears have not materialized, and craft is now more cooperative, doing write-ups, etc. The jobs have been broadened, with fewer work planners from management, and more union -based construction planners. "* Successful implementation of the "we culture" was reflected during the outage, when a safety railing was built by ironworkers on the polar crane around the upper edge of the fuel pool room, to prevent a 90-ft fall. An exacting and risky job, it required interdepartmental cooperation between operations and maintenance for its success. Overall, this outage was easier, shorter, and showed more interdepartmental cooperation than in the past, with fewer complaints about having to go to another department to do a job. "* Craft felt heard and supported in Outage Control Center meetings. More buy-in is still needed, with reassurance that the shared responsibility of the "we culture," is to be taken seriously, and not simply a "flavor of the month." When asked about how to handle the increase in error rate during outages, the overall response was as follows: D.4-7
"* Craft wanted feedback about how data is being used, and what is being done as a result, even if it's used only for trending. "* More important than the actual data collected is the presence of the supervisors in the field, allowing face-time with foreman. "* Operations appear to have the opposite experience. Being more independent, they resent feeling under scrutiny. To improve the situation, critiques should be oriented toward "acknowledgment for a job well-done rather" than "judgment (i.e. pointing out errors only)". "* Behavioral observation class in Operations has an accompanying video which works well as a teaching tool. The training department plans on a similar one for Maintenance. "* Department-specific observation cards were instituted by HP.
== Conclusion:== The supervisors seemed very open in their discussion of HP. Issues have been recognized and are being acted upon. 3.6 Incentives for Increased Physical Fitness, Attention Enhancement, and Stress Management The DCISC FF team met with the new Director of Operations, to discuss incentives for increased physical fitness, attention enhancement, and stress management, previously reviewed in the Annual Report, 2000 (Reference 6.1) and July 6, 2000 fact finding report (Reference 6.2). The Ops director had previously been a shift manager, shift foreman, and engineer at the plant. This gives him both a good working knowledge of control room conditions, and added respect from the operators. Operators are required to have 7.14 mets, a measure of aerobic fitness, with the ultimate decision left to the discretion of the supervising physician. Licensed operators who fail are designated as "no-solo." Since there are 4 licensees in the control room at all times, this is unlikely to be an important problem. (See report below on medical center visit) As part of the regular training, there has been scheduled a one-hour health class. However, it is often superceded by other more pressing matters. A more general issue is how to enroll the operators in a fitness program. Incentives for fitness were previously discussed relative to the security D.4-8

interpersonal, problems. All ECP contacts are documented in a log. Rather than a formal EC investigation, most are handled informally with discussion, intervention or mediation. One good preventive measure is supervisors and managers having a greater presence in the field. It was reported to the DCISC that the number of concerns being taken to the NRC has increased recently. Data show that the number at DCPP is twice the average in the NRC region. Allegations to NRC are higher: 11 (7 external, 4 internal) versus 4 in 1999, from all sources. The latest Synergy survey was just ending, with a return to date of 700, representing more than 50% of the organization, with an anticipated 900-1000 returns total. Results will be available by mid- to late January.
== Conclusion:== The Employee Concerns Program appears satisfactory. The DCISC should have a future fact-finding meeting to review the increase in employee concerns. The Committee should also review the specifics of how PG&E documents contacts described as "being handled informally." The committee should review a copy of the Synergy survey report when available, have it addressed at a fact-finding meeting, and have it presented at the next public meeting. 3.8 New Behavioral Observation Based Safety Process (BOBS) In response to a high injury rate, DCPP instituted a new program to track incidents, identify barriers to working safely and institute continuous improvement in work processes and practices. Called BOBS (Behavioral Observation Based Safety Process), it involves many levels of the organization: the steering committee, observers, employees, supervisors, management, and the safety department. Focus is on all components: person, conditions, behavior, and their relationship. A team of 25 trained craft people observe workers in the field, using a check list specific to DCPP (Reference 6.5). The individual evaluates a job in progress for 15-20 minutes, then immediately gives feedback, with emphasis on safe and at risk behaviors in a number of categories. With ensuing dialogue, both sides look for any barriers to job safety. This D.4-10

== Conclusion:== This is a work-in-progress. More detail will be presented by PG&E at the 2/01 Public meeting. 3.10 Medical Center Visit re Operator Fitness A meeting was held with the medical director Dr Georghiou, who is concerned, as has been the committee, about Operators' health and fitness, previously presented to the DCISC (Reference 6.7) He discussed the American National Standards Institute (ANSI) requirements for Aerobic Fitness. Their medical form has a "no solo" category for licensed operators who do not meet the required 7.14 mets. The ultimate decision is left to the discretion of the supervising physician. There are a number of "no-solo" operators, who are restricted because of poor health or fitness. There is no penalty to the operator for the classification, which can be due to a temporary condition such as post knee surgery, or in the first 2 years after a heart attack. The no-solo restriction stems from the old power plants that had only one operator at a time. Since there are 4 licensees in the control room at all times, this is unlikely to be an important problem. This is less of a problem with the larger number of operators on a shift. However, the issue arises as to how many "no solos" can one have at a time on a shift. Can they become a casualty during an emergency? D.4-12

While this may only be a case of indigestion, it is better to check it out (and be wrong) than miss a life-threatening emergency. He reviewed post-MI lifestyle changes and medications.
Conclusion:
The safety class on cardiac health was well attended, with an enthusiastic, involved audience. Covering complex material in an understandable way, the class made an excellent contribution to the health of employees and their families. It was apparent that the employees have a close and trusting relationship with medical center personnel, with many staying afterwards to ask questions or otherwise touch base with the doctor. Recommendation: It is recommended that the operators have the safety class on cardiac health as part of their training program, on video if not live (which is preferable).
4.0 CONCLUSION
S 4.1 The plant-wide Human Performance Programs have gained the full support of management. Although error rate appears to have increased, recent plans to reduce it seem promising. 4.2 It appears that PG&E is adequately addressing the issue of increased error rate in Maintenance. The DCISC should follow up on the following questions regarding error rate in Maintenance: "* Could the increase in error rate during outages also reflect increased overtime? "* Are there figures to correlate the two factors? "* What is the comparative error rate of employees vs contractors? One recent review of this issue indicated that there was no difference. "* Is PG&E addressing issues of maintenance worker fitness? The DCISC should request specific data regarding outage error rate of employees versus contractors. D.4-14

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate the the DCISC. The objective of specific safety matters for if PG&Es performance in safety matter review was to determine if any of these are important these areas is appropriate and follow-up, or presentation enough to warrant further review, matters include follow-up at a public meeting. These safety by the Committee as well as and/or continuing review efforts of reviews of various safety those identified as a result related documents. D.5-1
3.0 DISCUSSION 3.1 Transition Program to Prepare for Competition PG&E reviewed the status of the Transition Program for the year 2000. The Transition Program has been discussed at previous fact finding meetings and Public Meetings and the purpose of this discussion was to review the status of the program. The Transition Plan has been incorporated into DCPP Performance Plan or Center of Excellence (COE) Plan. The Performance Incentive Plan (PIP) and Performance is based on functional process. Budgeting is based on the four Core Processes and COE. The four Core Processes are:
- 1. Production - running the power plant
- 2. Manage Plant Assets - all things to maintain plant, long term plans and system support
- 3. Supply Chain - all things necessary to support plant
- 4. Revenue Realization The six Centers of Excellence are:
- 1. Engineering
- 2. People Performance
- 3. Business Support
- 4. Loss Prevention - fire protection/security
- 5. Information Management
- 6. Maintain License All personnel are in COE and then loaned out to the Processes.
The budget for the year 2000 was also reviewed as was the overall status of the DCPP Transition Plan. The statuses of each of the elements of the Transition Plan were discussed. These were: A. Transition Plan A-1 Disengagement Plan - Complete B. Cultural Enhancement Projects B-1 Cultural Transformation - Plan complete, in 2001 will move out to individual contributors B-2 Line of Sight/Performance Management complete C. Cost Reduction/Process Improvements D. 5-2
C-I Work Control - transfer to process owners, complete C-2 Secure the Plant - almost all complete C-3 Corporate Support Project - every year they will review G & A costs and they are pushing back corporate charges C-4 Firewatch Strategy - partially complete, will complete after IR10 - May 2001 C-5 Consolidate Record Management Systems - on hold, doing research D. Develop Competitive Business Processes D-1 Process Cost Management - complete D-2 Maximize Revenue - Plant Mods (includes Unit 1 uprate Decisions) - complete D-3 Post-CTC Corporate DCPP Strategy -strategies change D-4 Energy Marketing Process - PG&E did complete report and analysis D-5 STARS (Strategic Teaming and Resource Sharing) - still looking at different paths, sometime in 2001 D-6 Business Understanding - part of culture transformation, complete and into implementation Original plans had some assumptions that are no longer valid and will be revisited. Staffing at DCPP is currently at 1257. Over all, the Transition Plan is largely complete. The Business Support Group was also discussed. Upon questions from the DCISC Member about participation in the Human Performance area, the Manager of the Group stated that his group did not make any efforts in particular in the Human Performance area. They are aware of the overall plant efforts in the human performance area and when they support the plant during fuel outages, they get training in human performance.
== Conclusion:== It appears that DCPP has completed their efforts with the Transition Program and has the implementation well under way. 3.2 Engineering Work Load Performance Indicator Recommendation This item has been discussed at previous fact finding meetings and Public Meetings and the purpose of this D. 5-3
discussion was to review the systems they are using to measure performance and the status of the current indicators. The Manager - Engineering Services presented their workload and the indicators they use to monitor their performance. They track Engineering Services (ES) Action Requests (ARs) and Action Evaluations (AEs) by:
- ES Overdue Workload by Work Type
- ES In/Out by Work Type
- ES Total Workload by Work Type They also track Engineering Services by:
- ES Overdue Goal
- ES In/Out Trending Plot
- ES Workload Their goal for total ARs and AEs is to be down to 2000. In 2000 they trended down to less than 2000 and then up to about 2300 to 2400 and are now down to about 2000. Design Engineering spends about 80 -90 % of their time on ARs and AEs. Not all Engineers are doing things that can be tracked.
PG&E was asked how can DCPP look at total Engineering work load and how much manpower they have to get the work done. It also appears that PG&E does not have the ability to track all the work that is not covered by ARs and AEs and do not know that DCPP is doing everything that needs to be done. DCPP stated that they would rather measure how System Engineers are doing by how they are performing system walkdowns. In Design Engineering, they do not have enough manpower to do all the work that needs to be performed and some work has to be sent out to contractors (outsourcing). The Engineering Group did meet their deadline to get all the design packages to the outage group to support 2R10 refueling outage. There were 75 design packages for 2R10. They also have a process to screen design changes to prioritize them. The DCISC Member suggested that DCPP should have some method to identify the entire Engineering WorkLoad to determine if they have enough resources to perform the work without getting behind.
== Conclusion:== It appears that DCPP has methods to track performance and work load of ARs and AEs and looks at the D.5-4
they do not appear performance of System Engineers. However, that is not covered to have a method for tracking everything to by either ARs or AEs. They also do not have a method to determine if they identify entire the Engineering Workload the work without getting have enough resources to perform behind. a Recommendation: It is recommended that DCPP investigate Workload so they can method to identify the entire Engineering all the determine if they have enough resources to perform necessary work without getting behind. 3.3 Alternate Source Terms radiological source PG&E reviewed the NRC alternative on using terms (AST), potential benefits and DCPP position a new source term which is different than the AST. AST is information document current source term based on technical consequence calculations for (TID) 14844 for radiological dose an NRC accidents and is nuclear power plant design basis AST is based on significant accepted alternative to TID 14844. and in understanding the timing, magnitude, improvements from severe nuclear chemical form of fission product releases of TID-24844. The power plant accidents since the publication analyses using TID are results of design basis accident conservative and bound AST. December 1999 for public The NRC issued draft RG-1081 in 1.1183, subsequently issued Reg. Guide comment, and for Evaluating Design "Alternative Radiological Source Terms Reactors", in July 2000. The Basis Accidents at Nuclear Power also discussed. NRC Reg. assumptions of AST vs. TID-14844 were to nuclear power plant Guide 1.183 provides the guidance AST and NRC Standard Review licensees on implementation of radiological provides guidance on review of Plan 15.0.1 consequence analyses using AST. as a modification of the NRC defines full implementation characteristics of facility design basis that addresses all radioactive the AST, that is, composition and magnitude of the the timing of material, its chemical and physical form, and establishes the plant its release.

Also full as the new acceptance design term used in all replaces the previous accident source approved, all subsequent new basis radiological analyses. Once D.5-5
or update analyses would be based on the approved AST and TEDE criteria. NRC defines selective implementation as a modification of the facility design basis that (1) is based on one or more of the characteristics of the SAT or (2) entails re-evaluation of a limited subset of the design basis radiological analysis. Use of other characteristics of an AST or use of TEDE criteria that are not part of the approved design basis, and changes to previous approved AST characteristics, would require prior NRC staff approval. A selective implementation of an AST should ensure that all (radiological and non-radiological) significant potential impacts have been identified and evaluated for the proposed plant modifications in the context of AST. The AST implementation acceptance criteria was also reviewed. The potential benefits in implementing the AST are:
- Increase in allowable containment leak rates.
- Simplify the control room filtration system by changing the number and/or types of filters.
- Increase in allowable valve stroke times for containment isolation valves
- Increase post-LOCA recirculation leakage.
- Relax equipment qualification requirements by reducing EQ concerns for the equipment required to be operable in the short-term.
- Relax containment isolation requirements
- Eliminate or limit containment spray additives, or improve operating margin for containment pressure.
- Update plant accident atmospheric dispersion factors(x/Q) using current meteorological data.
DCPP status on using AST is:
"* Currently DCPP has sufficient margin in all of the design basis accidents except SGTR, which is being reanalyzed by Westinghouse using TID. "* There are no immediate needs for reanalysis using AST at this time. " The cost and benefit for reanalysis using AST are uncertain. " PG&E will continue to monitor other utilities progress in their implementations of the AST.
D.5-6
converting In summary, utilities can stay with TID instead of would have to totally redo to AST. To implement AST, utility are using AST to reanalyze all calculations. Some utilities while others are looking at design basis accidents for SGTR, redoing all accident analysis using AST. states that the AST is not The NRC Reg.

Provide a learning environment for potential future arrangements The overall purpose is to realize benefits through joint cooperative arrangements that may not be obtainable as individual facilities. Their plans for 2001 include consideration of options for conducting a Joint Nuclear Operating Company or a Generation Company (JNOC/GENCO) feasibility study. They will continue with additional initiatives and have formed implementation teams for certain areas. The teams are made up of employees from each plant and STARS has two full time employees.
The three phases for 2001 are: 1) determine what the value is for each utility, 2) once there is a value, develop business plan, and 3) develop implementation plan. This should be completed by end of 2001. The only negative effect they can see is taking resources away from plant activities, but the positive effect of this is developing communications between utility groups or networks. STARS is also trying to monitor any effect of alignment on performance.
== Conclusion:== PG&E appears to be taking appropriate steps to evaluate the benefit of participation in STARS from both safety and economics. There appears to be many advantages in joining with the other utilities in the operation of their nuclear plants. DCISC should continue to monitor this program as it proceeds. 3.5 Top Ten Quality Problems The DCPP NQS Supervisor discussed the NQS Quality Problem Action List for Aging Quality Problems. The list contains Nonconformance Reports (NCR), Quality Evaluations (QE), and "A" Type Action Requests. The list identifies the oldest quality problems in each of the QP reporting methods. It includes the title of the problem, the remaining actions, and responsibility for resolution of those actions along with the required completion dates. Quality problems on the list may not necessarily be old, but may need attention by the line organization. He also reviewed NCRs and QEs, which they felt, were the most important quality problems. These were:
- NCR - N0002101 - Seismic adequacy of non-bearing walls in EDG rooms. This NCR is scheduled to be completed by 12 31-01. The NQS committee that reviews these is concerned D. 5-8

once each month. Security Services has not formalized a Human Performance Program like the other departments have. The Director is on the DCPP Human Performance Steering Committee. He also stated that Security should consider doing more in improving human performance. They have started trending information on how security personnel impact security events.
Conclusion:
It appears that the performance of the security computer has improved during the year, but they still need to complete the correction of the problems. DCPP also needs to develop long term plans for the security equipment. Recommendations: It is recommended that the DCPP Security Services develop Long Term Plans for the Security Equipment. It is recommended that DCPP Security Services develop a program for improving human performance. 3.7 Self-Assessment Program Update A formal self-assessment program was implemented at DCPP in November 1999. The program structure included a defined owner, a program guide, management oversight, and designated department self-assessment coordinators. The self-assessment program has been discussed at previous fact finding meetings and Public Meetings the purpose of this meeting was to review the status of the program for this year. They have completed 18 self-assessments in the 3rd. quarter and 43 for the year 2000. Each department is setting goals for how many self-assessments they will do each quarter and the numbers are being trended as part of the performance assessment. NSOC commented 1IA years ago that DCPP was behind the industry in self-assessments. They now say that DCPP has improved, but they can still make improvements in this area. PG&E thinks they are above average, though some departments can still improve. The numbers of self-assessments made each year is about 50, which is above the standard 40 to 50 reports, is about the right number. DCPP does not need to do more self-assessments, but self assessments and reports need to be improved. Critiques are performed for every assessment and the results provided back to the team leader and the Self-Assessment Advisory Board. The D. 5-10

worrying about outside events. Color coded work packages may also be part of the problem. The work may be put on the wrong color package. The Team Leader discussed Industrial Safety vs. 1R10 schedule. In IR10 PG&E made a big effort (all meetings) to employees that safety was the focus. They had a short outage schedule, but that safety was first. There was also a big push on ALARA in IR10. Asset Teams said they had to focus on each job. They did not meet the goal, but they did better than any other outage for Unit 1. The corrective maintenance (CM) backlog and schedule adherence for the year was reviewed. The present CM backlog is 556 with a goal of 425. Operations and Maintenance are doing very well in prioritizing the jobs that need to be worked on schedule. The issues facing the Assistant Team Leaders (ATL) were described. DCPP needs to make the ATL jobs easier as DCPP has added more work to the ATL, which is one of the hardest jobs on site. The ATL are not able to do everything that they are expected to do. The NSSS Team is changing the way they use the ATL. They have one ART direct the work one week while the other ATL is planning work for the next week when he will be directing the jobs. The Team Leader feels that the Asset Teams have been successful. Work is getting done more effectively and workers are sharing work better. This is building a lot of ownership into the work force, though it can still be improved. When asked how the other departments would view Asset Teams performance, he stated that he thought that Operations and System Engineers would say that Asset Teams are doing well. The foremen were given tests in all disciplines to determine if they needed cross discipline training and system training. If so, the training has been ongoing and will be completed in January 2001. Training on performance review and giving employee feedback has being ongoing and will continue. Training on safety issues has also been continuing.
== Conclusion:== It appears that the Asset Teams have been making progress in improving overall performance of the group. They have made improvements in industrial safety and ALARA in 1R10. They have also determined the training necessary for the Foremen in each of the disciplines and the training should be complete in January 2001. D. 5-12

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate specific safety matters for the DCISC. The objective of the safety matter review was to determine if PG&E's performance in these areas is appropriate and if any of these areas revealed observations which are important enough to warrant further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee as well as those identified as a result of reviews of various safety related documents. 3.0 DISCUSSION 3.1 DCISC Performance Indicators The DCISC Fact-finding Team met with Stan Ketelsen to review the DCISC Performance Indicators (PIs) to determine if some indicators could be eliminated to reduce duplication with NRC or INPO indicators as was requested at the February 7-8, 2001 Public Meeting. A previous DCISC fact-finding review was made in July 2000 in which two indicators (No. 4, Maintenance Services Rework Event Trend Records [not significantly meaningful to DCISC] and No. 5, System Health Indicator [not fully developed]) were eliminated (Reference 6.1). The DCISC PIs are shown in Attachment 1 and are derived from PG&E's comprehensive indicators. The Fact-finding Team reviewed each of the DCISC PIs as compared to the NRC (Nuclear Regulatory Commission) PIs (Attachment 2) and the INPO (Institute of Nuclear Power Operations) Performance Indicator Index. The criteria used to eliminate particular DCISC indicators were as follows:
- 1. The indicator exists in other available measures, and
- 2. The indicator can regularly be made visible to the public by the DCISC, or
- 3. The indicator is not significant to DCISC.
D.6-2
The following recommendations resulted from the review: DCISC Performance Indicator Recommendation Reason
- 1. Radiation Exposure Replace Use NRC, INPO PIs & outage results reports
- 2. Personnel Contamination Replace Use outage results reports Incidents & fact-finding meetings
- 3. Meeting Corrective Action Eliminate Results included in No. 8; Due Dates review in annual CAP review

- 20. Vital Area Events Replace Use NRC PIs (Confidential) I II D. 6-3
Indicators which are to be replaced with reviews/reports in DCISC fact-finding reports will be added to the DCISC Open Items List for assurance of continued monitoring and reporting. By virtue of these indicators being reported in fact-finding reports, they will be reported at public meetings and in the DCISC annual report such that the public will be kept advised. The DCISC should request that PG&E regularly report on the following indicators at DCISC public meetings:
- 1. DCPP Performance Plan (see Section 3.15 below)
- 2. NRC Performance Indicators
- 3. Maintenance Rule Quarterly Report to Management
- 4. Refueling Outage Results
- 5. DCPP Performance Indicators INPO indicators will be reviewed by the DCISC in fact-finding meetings.
== Conclusion:== The existing set of DCISC performance indicators can largely be replaced with other existing indicators contained in PG&E, NRC and INPO reports. Other indicators not included in these reports will continue to be reviewed in DCISC fact-finding reports and reported in public meetings. The DCISC should request that PG&E regularly report on the following items at DCISC public meetings: (1) DCPP Performance Plan, (2) NRC Performance Indicators, (3) Maintenance Rule Quarterly Report to Management, and (4) Refueling Outage Results. The DCISC should consider process-based measures as DCPP moves to a process-centered arrangement. 3.2 Meeting with New NRC Resident Inspector The DCISC Team met with Terry Jackson, a new NRC inspector in residence at DCPP, added to support the Senior Resident Inspector, David Proulx. DCISC Member Rossin and Consultant Wardell met with Mr. Proulx at the October 25-26, 2000 fact-finding meeting (Reference 6.2). DCISC Member Clark described the history, function, organization and activities of the DCISC, including fact-D. 6-4

Clark invited Mr. Jackson to a DCISC 3.3 NRC Report on Refueling Outage Risk Outage Director, and The DCISC Team met with Brad Hinds, Assessment Ken Bych, Supervisor of the Probabilistic Risk safety Group, to discuss a recent NRC report on outage (Reference 6.3). The NRC report analyzed data from 19 refueling outages, (PWRs) and 3 boiling including 16 pressurized water reactors included DCPP-I and -2. water reactors (BWRs) . The PWR list to gain an understanding The purpose of the study was for NRC from two perspectives: of the overall risk of each refueling The NRC impact risk. plant configuration risk and modification risk each owner had performed an outage reported that qualitative and 16 were assessment for each outage; 3 were 91-06, All followed guidance in NUMARC quantitative.

concluded that it received increased attention and awareness which lessened its impact. Additionally, generic risk profiles were generated for PWRs and BWRs. The NRC noted, as did the DCISC, that there was a wide range of risk values observed in the estimates of both the cumulative outage risk and peak risk. This was attributed to differences in modeling and other related data issues as opposed to actual differences in risk. DCPP personnel were familiar with the study and had performed "a full plant-specific, operational risk assessment as well as "a generic industry modeling of shutdown risk. DCPP has begun a formal, comprehensive, plant-specific shutdown risk analysis, which it expects to complete in 2002. They currently estimate outage risk at about 10-20% of total plant risk. Upon completion of the full shutdown analysis, DCPP will be able to compare risks in it and the operational assessment to better determine when or whether to perform on-line maintenance.
== Conclusion:== The wide range of NRC-reported industry plant shutdown risk values was attributed to differences in modeling rather than differences in actual risk. DCPP has begun a comprehensive, plant-specific shutdown risk analysis to be completed in 2002. The DCISC should follow up at that time. 3.4 On-Line Maintenance The DCISC Team met with Brad Hines, Outage Director and Ken Bych, Supervisor of the Probabilistic Risk Assessment (PRA) Group to discuss the status of DCPP on-line maintenance (OLM). The last review of this subject by the DCISC was in December 1999 (Reference 6.4). That review concluded that DCPP was using OLM more often to reduce outage scope and was developing and updating its risk assessment tools to appropriately control the resultant risk of removing components from service during operation. It was reported that NRC Regulation IOCFR50.65, "Maintenance Rule" Paragraph (a) (4) had become mandatory in November 2000 in that the risk assessment requirement "shoulds" were changed to "shalls". Also, NRC Regulatory Guide 1.182 "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants", which embraces NUMARC 93-01 "Industry Guidelines for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants", is more closely focused on managing the calculated D.6-6
DCPP had revised its risk associated with maintenance. new requirements. maintenance program to implement the in September 2000 to determine A self-assessment was performed the new requirements. The the readiness of DCPP to implement personnel and a Maintenance team consisted of several DCPP a STARS representative from Callaway Nuclear Plant, Rule of the necessary elements member. The results showed that many were in place in the existing PRA and On-Line Maintenance were made: Programs, but the following recommendations

to the November 28, 2000 DCPP made these changes prior involved implementation date. The primary procedural change Procedure AD7.DC6, which DCPP's on-line maintenance procedure, (Reference Risk Assessment" was renamed "On-Line Maintenance trip risk builds on the existing 6.5). This procedure MA1.DCl0, "Troubleshooting and assessment actions of Procedure MAl.DCll, "Risk Level Assessment" and Procedure Risk Changes to Procedure AD7.DC6 Assessment of Non-Routine Work". included the following additions: Phase

D.6-7
requires an assessment of the plant trip risk with a checklist for both pre-planned and emergent activities. Formal classroom training (Reference 6.6) has been provided to Maintenance and Operations personnel on the new requirements. Additionally, just-in-time (JIT) tailboards are provided prior to performance of maintenance activities. The training and JIT tailboards are meant to provide a higher awareness of risk in the Control Room. Additionally, with the move to Standard Technical Specifications, the On-Line Maintenance Program (OLM) (used to assess risk), can take advantage of the 7-day component outage-window rather than the previous 72-hour window. An NRC inspection was performed in February 2001 of various plant activities, including maintenance risk assessment. The NRC inspectors concluded that DCPP had exhibited good use of the Maintenance Rule and provided good, effective compensatory measures when two risk-significant components were inoperable during California Grid Stage 3 alert conditions (i.e., possible increased electrical grid stability) . A special risk management guidance statement had been developed at DCPP identifying additional reactor trip risk classifications for the 500 kV electrical system and the 230 kV start-up power system during Grid Stage 3 alerts. The California electricity supply shortage and increasing grid alerts have caused DCPP to defer some equipment maintenance during these periods to reduce the risk of plant trips. The DCISC inquired as to the effect on reliability. DCPP's practice was to move the equipment to a later maintenance window but they did not believe reliability would be affected; however, possible effects could be larger scope outages and a shift in focus from summer to winter. DCPP noted that the capital budget had been lowered due to PG&E's debt problems and that revised plans for spending were under development. The DCISC believed it should follow up this item due to concerns of long-term reliability if spending is significantly lowered or delayed. Reference was made to a new initiative, Passive Device Aging Management Investigation, which was begun in late 2000. Completion is expected in June 2001. The DCISC should review the program results subsequent to June. D.6-8

January 2000 and the next one was planned for Fall of 2001. The DCISC Team reviewed the current three-year plan (CAP/HP Programmatic Upgrade Action Plan) which included results from the following:
- January 2000 self-assessment
- NSOC reviews
- 2000 NRC inspections 0 Various ARs written on the CAP
- 2000 NCV self-assessment 0 2000 NEI Benchmarking effort o Reviews of other Plant CAPs The plan appeared comprehensive, and most actions had been completed. The remaining items were to be completed by early 2002.
Mr. Terrell reported that one member of his Group was assigned as "Cause Mentor" to critique cause code analysis for consistency and improvement. He believes DCPP has solved the cause code assignment problems. The DCISC was interested in reviewing results of NCR cause code assignment analysis and requested information on that subject. The DCISC reviewed the Cause Code Critique, a document providing guidance for review of cause code analysis and assignment. The document included a critique form, directions, areas to be reviewed, a grading scale, space for comment, expectations for cause analysis documentation, and process documentation for the user. The guidance appeared satisfactory. The grading scale was numbered from 1 to 5, with 1-2 being "requires improvement", 3 "adequate", and 4-5 "excellent". There was no opportunity for review of actual critiques because the process had just been developed. NSOC has been reviewing the CAP and is carrying it as an open item. NSOC has established a CAP Subcommittee, which will begin to review CAP following Outage 2R10. The DCISC should review this at the May 2 NSOC Meeting. The CAP Group performs a mandatory effectiveness review of each NCR corrective action following closeout as directed by the Technical Review Group. An adverse trend analysis is beginning to be developed quarterly with a newly installed computer program. CAP is developing leading and lagging CAP effectiveness indicators. D. 6-10
the lagging and leading indicators The DCISC reviewed for indicators had been formulated developed to date. Lagging the following areas: (trend of numbers of ARs
"* Problem identification initiated) timeliness of reviews "* Problem review (six measures of and numbers of QEs and NCRs) measures, including cause "* Problem analysis (four rate, and quality analysis average age, NCR rejection grade of QEs and NCRs) corrective actions (seven measures, "* Timeliness of action document average including various corrective ages, actions overdue, etc.)

Conclusion:
The DCPP Corrective Action Program appeared to have been improved as a result of self-assessments, external evaluations and reviews of other plant CAPs. Measures of program effectiveness were just being developed and appeared headed in the right direction. The DCISC should review the CAP in early 2002, following completion of improvement action items and the next self-assessment. Recommendation: Because the predominant cause of events is human error, DCPP should more closely coordinate the Corrective Action and Human Performance Programs and utilize training in human characteristics and skills (e.g., interviewing skills, human error characteristics) for personnel preparing root cause analyses and corrective actions. 3.6 Winter Storm Experience/Procedures The DCISC Team met with Paul Roller, Director of Operations Services to obtain an update on DCPP's experience with winter storms during the 2000-2001 winter storm season and to review any changes in storm response procedure. The DCISC last reviewed this subject in May 2000 (Reference 6.8). In that review, DCPP's policy was to maintain the plant in a safe condition while maintaining a low reactor power level. It appeared that DCPP had developed an effective tool and process for responding to winter storms without having to shut down the plant. The plant storm response had been based on the "P9" plant protection level of 15% power for the most severe storms. In this case PG&E could take the plant down to approximately 15% power (with a turbine trip but without need for the condenser circulating pumps, the component most affected by the storm) and ride out the storm without having to scram the reactor. DCPP had raised the limit of the P9 protection level from 15% to 50% along with the new Standard Technical Specifications; however, procedurally DCPP would now normally run back to 20% (maximum limit of 25%). This decision (and a decision to shut down) is made with the aid of a prepared storm evaluation chart and a plant simulator run. The evaluation sheet includes such parameters as swell strength, wind direction and strength, kelp loading, etc. If a storm is severe enough, the plant will be fully shut down. D.6-12

Ninety environmental reports were completed on schedule during 2000. An entrainment study report was submitted in March 2000 to the Regional Water Quality Control Board. The Board had issued a draft report, and PG&E was resolving outstanding issues. The primary resolution to settle impingement and thermal effects issues was to set aside land for conservation. This was not expected to affect plant systems or operation. DCPP will submit its Annual Non-Radiological Environmental Report by the end of May 2001, and copies will be sent to the DCISC.
== Conclusion:== DCPP 2000 environmental performance appeared satisfactory. 3.8 RCS Hot Leg Flow Measurement The Fact-finding Team met with Bill Bojdhi, an engineer in the Reactor Engineering Group for an update on Reactor Coolant System (RCS) flow measurement. This topic involved the development of a new analytical model for the existing flow instrumentation to permit increased operating margins, specifically full power operation with the Technical Specification 15% steam generator tube plugging limit. The DCISC last reviewed this topic in May 2000 (Reference 6.10). At that time several other nuclear plants had obtained NRC approval to use the new methodology, and DCPP was preparing a new submittal to NRC. NRC had not approved a previous DCPP submittal because of hot leg thermal streaming, which could adversely affect the readings. DCPP is sending operating data to Westinghouse for the development and substantiation of a DCPP model; however, there was no money budgeted for 2001 for the development. Revised analysis and a Westinghouse topical report are planned for 2002. Other plants have made submittals to NRC and have received approval. Sequoyah utilized IOCFR50.59 for the change, but NRC is not accepting this approach any longer. South Texas Plant received approval but is not using the model.

Womack reported that at the current 3.5 cents per kilowatt hour DCPP was earning the necessary revenues for planned capital spending to continue. This was already part of the cost reduction plan, which had been approved several years ago. The company was evaluating a lower return model, but Mr. Womack had no information on it.
== Conclusion:== It appeared that two of the three DCPP officers were continuing full-time on plant responsibilities. The third, Greg Rueger, Senior Vice President and Chief Nuclear Officer, still had other corporate duties, although he was spending a substantial amount of time on DCPP. This appeared acceptable to the DCISC, which, however, will remain alert to detect any future reduction in plant safety. 3.10 Auxiliary Saltwater System Review & Tour with System Engineer The DCISC fact-finding team met with Joe Anastasio, System Engineer for the Auxiliary Salt Water System (ASW), to review the system and perform a system walkdown. This was the first DCISC review of ASW. The ASW System supplies cooling water to the Component Cooling Water heat exchangers from the ultimate heat sink (Pacific Ocean) in order to reject heat from primary plant systems. The review started with a description of the system and its design bases using basic flow diagrams. Each major component was described. The only significant active components are the redundant Auxiliary Salt Water Pumps located in the Intake Structure. There are two ASW Pumps for each of the two redundant trains of the system. Each pump is located in a watertight compartment to prevent water damage to the motor as a result of flooding or tsunami. Watertight doors assure that flooding of one compartment does not affect the opposite train operability, thus maintaining safe shutdown capability. Mr. Anastasio reported that an ASW Pump could be replaced on-line, if necessary, in about 60 hours as compared to the 72-hour Technical Specification allowed outage time. The discussion included ASW system long-term plans. These are plans developed by each system engineer for system improvements, upgrades, modifications or major repairs/maintenance to assure long-term reliability. The plans for ASW appeared satisfactory. D. 6-16

and self-assessments. The DCISC had decided to continue to monitor the program performance. The purpose of Configuration Management is to assure consistency between design requirements, physical configuration and facility configuration information (i.e., as-built documents, including procedures). Mr. Shelby described the current CMP referring to the controlling directive (Reference 6.12) and described recent program changes. CM is implemented through more than 200 plant procedures, which conform to the controlling directive. Changes consisted primarily of augmenting the implementing procedures to include CM guidance and a checklist and better instructions for assuring that the impact of any change is reflected in all related documents. The program meets the requirements of the applicable industry standard (Reference 6.13). Effectiveness of CM is measured by the CM Index, which measures the following five areas related to CM:
- 1. Corrections and changes to controlled drawings are processed in a timely manner.
- 2. The Component Data Base (CDB)is updated in a timely manner.
- 3. Design Criteria Memoranda (DCM) are maintained accurate by processing changes in a timely manner.
- 4. Drawings are revised in a timely manner and are legible and accurate.
- 5. Temporary configuration changes to the plant are minimized and removed in a timely manner.
The only adverse trend has been related to the maintenance of the Component Data Base where an NCR had just been cleared with corrective actions to improve the consistency of updating the database. Self-assessments are being used to determine whether the issue has been resolved. The program manager searched the last two years of quality problems, and except for the aforementioned NCR, there were no significant problems, just small administrative matters. There have been no NRC Notices of Violation of CM in the last two years. The next self-assessment of CM is planned for July 31 - August 10, 2001 and will include personnel from other (STARS) plants.

review all engineering programs together in a single fact finding meeting in the future. This plan will be included in the DCISC Open Items List.) 3.13 Reportable Items in Outage IR10 The DCISC Team met with Roger Russell to review NRC License Event Reports (LERs) from Outage 1R10. The last review of Outage 1R10 was in mid-outage in October 2000 (Reference 6.15) in which three LERs were reviewed. Since then, as reported in the DCISC Public Meeting in February 2001, five LERs were added for an outage total of eight. Four were caused by personnel error, and the remainder by equipment failure (3) and poor contractor culture (1). Overall, for year 2000, 16 LERs have been submitted, nine of which were caused by personnel error. The discussion centered on personnel errors and plans to improve human performance. Human error rates have been increasing with the rate at the end of 2000 at 1.25 errors per 10,000 work-hours. The rate had been as low as 0.75 in mid 1999 and 0.9 in mid-2000. An analysis of Operations significant error precursors in outage 1R10 had shown that there were 40 known significant and less significant errors. Lack of attention to detail was the overwhelming cause of these errors. The predominant outage-related precursors were
- High workload
- Unfamiliarity with the task (or first-time task performance)
The predominant individual (human) precursors were
- Distractions/interruptions
- Complacency/overconfidence (eight-of-the-ten significant errors involved operators with seven or more years experience)
- Night shift or recent shift change (80% of the significant errors occurred on night shift)
- Identical and adjacent displays or controls
- Imprecise communication habits None of the errors was considered system-induced. PG&E determined that the majority of these errors were preventable through the use of good self-verification, concurrent D. 6-20
independent verification and the practice of STAR (Stop, Think, Act & Review). DCPP has been implementing programs to improve HP. One program is called "Good Catches" which is a strategy for proactively identifying positive behaviors. Supervisors were trained to look for (and recognize in feedback) examples of exemplary performance, application of key behaviors, use of internal/external operating experience, and safe work practices. A number of good catches have been identified across the plant's organizations, mostly in Maintenance and Operations. The Human Performance Steering Committee has been formed. Key objectives include (1) development of a common philosophy and strategy for HP improvement ensuring the objectives are linked to NPG's overall operational plan and (2) to champion HP improvement within NPG, the industry, and with the regulators. Members include the Plant Manager and his direct reports (the plant Directors) and the Managers of NPG Learning Services, Corrective Action Group, and Generation HR. The HPSC typically reviews the following:
- Current leading and lagging HP indicators
- Self-Assessment summaries (for HP-related issues
- Industrial Safety Summary
- Human Performance Review Committee Minutes
- Current status of long-term strategic plan
- Emerging issues (DCPP-specific and industry)
HP Fundamentals Training will be provided to all Operations, Maintenance and Engineering personnel with initial training to be completed by the end of 2001. Continuing training is also planned. The instructor's guide for HP refresher continuing training for Operations (dated December 2000) was reviewed. The lesson plan covered the following items:
- Definitions of performance, human error, knowledge based performance, error precursors, error-likely situations, and error management
- Two types of error: active and latent
- Error modes: skill-based, rule-based, and knowledge based errors
- How humans process information D. 6-21
"* Task characteristics: task demands, individual capabilities, work environment and human nature "* Error-likely situations "* Anatomy of an event This type of training, the basics of how, why and when humans cause errors, appeared useful in getting the Operations front line workers to understand human information processing and error causes.
A DCISC fact-finding team plans to review human performance and the HPSC in June 2001.
== Conclusion:== DCPP appeared to take a reasonable approach to the analysis of causes of reportable events during Outage IRlO. The predominant cause was human error, and they are taking additional steps to improve human performance with new programs and organization and training focused more on human behavior. The DCISC should continue to follow the DCPP human performance programs. 3.14 Performance Plans The Fact-finding Team met with Terrell McKnight of the DCPP Business Support Group to follow up on an item from the February 2001 DCISC Public Meeting on DCPP performance plans (Reference 6.16) . PG&E covered the high level strategic plan at the public meeting, and the DCISC was interested in the lower level implementing plans and the DCPP Performance Plan. The overall DCPP Performance Plan contained results achieved in 2000 and those to be achieved in 2001 - 2004 (and beyond) The major areas of focus were as follows:
"* Safety - be the best operating nuclear plant in the western US measured by number of personnel injuries, amount of collective radiation dose, number of event-free days, no environmental protection program violations, green NRC emergency planning window and no cited violations, effective corrective action program implementation, and safety culture survey action implementation. "* Industry Leadership - be the best operating nuclear plant in the western US measured by all green NRC ratings for D. 6-22
Performance Indicators, DCPP self-assessment program recognized as industry leader with a defined minimum number of assessments completed, INPO # I rating, INPO composite performance indicator in top quartile, no significant INPO findings, and cost-effective improvements to DCPP appearance. "* Generation Performance - provide reliability/ predictability of production measured by amount of generation, outage time and cost, operating capacity factor, hourly generation level, unplanned capability loss, and submission of LAR for Used Fuel Storage Installation. "* Financial Performance - be a cost-competitive facility measured by a revenue target, operating cost, capital cost, nuclear fuel expenditure reduction, making a decision on the future of STARS, budget and performance aligned and managed by process, utilizing the Long Term Planning Process, and STARS savings exceed expenditures for the year. "* People
"* Performance as measured by compensation/
incentives/rewards clearly linked to results and performance, management performance assessments on trimester basis, and annual Bargaining Unit Employee performance assessments.
"* Development as measured by supervisory skills assessments, technical skills development, effective/
accredited operator programs, effective/accredited maintenance/technical programs, 100% successful initial license classes, and implementation of a continuous Human Performance training program.
"* Sustain An Excellent Workforce as measured by long term staffing plans, an effective Affirmative Acton Plan, and effective hiring while maintaining overall NPG headcount. "* Learning Organization as measured by expectations established for individual contributors to model desired behaviors, effective supervisory leadership skills, individual contributors participating in new culture, employees accept STARS, systems and infrastructure in-place to sustain new culture, and benefits are realized from process centering.
D.6-23
The overall DCPP Performance Plan was broken down into the following process-based and Center-of-Excellence-based Performance Plans. This is a new breakdown for DCPP and a departure from the previous functional organization.
"* Production "* Manage the Plant Asset "* Manage Supply Chain "* Engineering Center of Excellence "* Maintain the License "* People Performance Center of Excellence "* Information Management "* Business Support "* Loss Prevention These process plans contained process-specific actions and numerical measures for the period 2001-2004 in the categories of Safety, Industry Leadership, Generation Performance, Financial Performance and People. These strategies, measures and goals are aligned with the higher-level DCPP goals.
Individual manager and contributor performance plans will be aligned with these goals. Thus, each employee should have a "line of sight" from his/her individual and team plans to the DCPP plan. Nuclear safety was included in these plans in the following measures/goals:
"* A maximum total collective radiation dose "* Effective Corrective Action Program "* Green NRC Emergency Preparedness Indicators and no cited NOVs "* Improvements in Safety Culture Survey "* All green NRC performance indicators "* Effective self-assessment program "* INPO #1 rating, top-quartile composite plant performance indicators and no significant findings "* A minimum operating capacity factor These were further specified in the process-based plan actions and measures.
== Conclusion:== Based on a presentation and review, the DCISC Fact-finding Team believed the hierarchy of DCPP performance plans represented an effective method of disseminating D. 6-24
Nuclear management expectations to the whole organization. The DCISC should follow up safety was appropriately addressed. the plans are being periodically to asses how effectively implemented. 3.15 Control Room Tour Paul Roller, Manager of The DCISC Team met with of the recently re-configured Operations Services, for a tour Control Room DCPP had implemented a new Control Room. complex the Control Room formality policy and had re-arranged the operators.

feedwater flow and lost generation. Another possible effect is reactor overpower which occurred at the Salem Nuclear Station where licensed power was exceeded in 1994. The lesson included the following:
"* Technical basis for performing the procedure "* Review of the Salem Nuclear Station event (INPO SER 11-94) "* Frequency of performance "* Theory of ultrasonic flow measurement "* Performing Procedure PEP M-98A "* Review of the lesson with questions and answers A student handout was provided which included pertinent drawings, theory and equations, equipment set-up, and other technical and procedural information. The instructor distributed photographs of clean and fouled nozzles. The instructor maintained good interaction with the class by asking questions and stimulating discussion. Following the classroom session, the STAs went into the plant and actually performed the procedure (not observed).
== Conclusion:== The Shift Technical Advisor qualification training in performance of the DCPP procedure for setting final feedwater nozzle venturi readings by ultrasonic crossflow appeared appropriate and effective. The instructor exhibited good knowledge of the subject and interacted well with the students. 3.17 Observe Brown Bag Management Discussion Consultant Wardell attended and observed a weekly Friday management/employee discussion called the "Brown Bag Management Discussion". The meeting is open to any employee and is held in the plant auditorium. The subject of this discussion was the recent Institute of Nuclear Power Operations (INPO) evaluation of DCPP. Attendance was moderate. Operations Director Jim Becker described the high-level findings of the INPO evaluation. The group asked some questions, and Mr. Becker provided additional details of the evaluation and possible actions to D. 6-26
be taken by DCPP. Although open for other questions, no additional questions were asked.
== Conclusion:== The "Brown Bag" discussion of the recent INPO evaluation by management for employees appeared to be a good communication tool for DCPP. 3.18 Observe Multi-Facility Table Top Emergency Exercise Consultant Wardell observed two "table top" emergency drills of two emergency organizations on Friday March 16, 2001. The Technical Support Center (TSC) and the Emergency Offsite Facility (EOF) [and associated Unified Dose Assessment Center (UDAC)] were exercised independently with participants playing their roles around tables in their respective facilities without outside participation, hence the term "table top". Each organization participated in two separate predetermined scenarios. Each scenario included objectives for evaluation. The overall purpose of the drill was to enhance the Emergency Response Organization (ERO) knowledge and performance. In general, the high-level objectives were as follows:
"* Timely and accurate classification of events "* Timely and accurate notification of offsite governmental authorities "* Timely and accurate development of protective action recommendations for offsite authorities Technical Support Center (TSC)
Consultant Wardell observed Scenario #1 in the TSC. The facility had been rearranged since the last DCISC visit and exhibited improved utilization of space, thus benefiting communications. The initial events were typical, i.e., loss of essential equipment, in this case, Auxiliary Salt Water (ASW) Pumps (during a winter ocean storm) and additional equipment such as Auxiliary Feedwater Pumps. The scenario proceeded through all emergency action levels (EALs) to a General Emergency (GE). The TSC was staffed in a timely manner and proceeded to establish communications and plant status information flow. Support teams represented were engineering, radiological assessment, and government liaisons. Status and prioritized action boards were maintained. Regular status reports were D. 6-27
made. EALs were decided and announced in an accurate and timely manner. The demeanor in the TSC appeared to be organized and professional. There was good use of three-way communication. The critique received good participation, and it appeared to be on target. There were no major problems, and areas for improvement included improved information flow and shorter tailboards. The participants and monitors agreed that all objectives were met. Emergency Offsite Facility (EOF) Scenario #2 was observed at the EOF. The EOF was partially staffed with representatives from engineering, radiological assessment/monitoring, ERO management, and government liaisons. This scenario was initiated by an earthquake resulting in loss of all offsite power and a small steam leak from a steam generator in containment. An emergency diesel generator failed to start, and auxiliary feedwater pumps tripped, resulting in loss of the ability to maintain hot shutdown conditions. The players recognized the conditions and proceeded to General Emergency. Protective actions and notifications appeared accurate and timely. Radiological monitoring teams were controlled appropriately and provided good input. Three-way communication was apparent. Radiological assessment by UDAC appeared to provide timely and accurate assessments. The EOF critique appeared productive. Emergency action levels were done correctly, as were protective action recommendations. Status briefs were short and to the point. Engineering was effective, and government notifications were done well. UDAC performed well (in what was considered a particularly challenging scenario) . One area for improvement was to use fewer acronyms and less jargon, particularly with the county. The monitors and participants concluded that all objectives were met.
== Conclusion:== Both the Technical Support Center and Emergency 0ffsite Facility (including UDAC radiological assessment) appeared to perform and critique themselves effectively in the two emergency drills. D. 6-28

4.7 DCPP is proceeding slowly on using the new Reactor Coolant System hot leg flow measurement methodology due to budget considerations; however, there is no adverse safety impact and no urgency until steam generator plugging gets close to the 15% limit. With the long time, which has passed since this program was started, and the mixed results with similar projects in the industry, PG&E may wish to re-examine its plans. 4.8 It appeared that two of the three DCPP officers were continuing full-time on plant responsibilities. The third, Greg Rueger, Senior Vice President and Chief Nuclear Officer, still had other corporate duties, although he was spending a substantial amount of time on DCPP. This appeared acceptable to the DCISC, assuming no reduction in plant safety was indicated. 4.9 The Auxiliary Salt Water System, DCPP's connection to its Ultimate Heat Sink (the Pacific Ocean), appeared to be in good operating and readiness condition. The System Engineer appeared to be knowledgeable and up-to-date on the system design, performance and health. 4.10 The Configuration Management Program at DCPP appeared satisfactory with measures in place to gauge the ongoing program effectiveness, which the DCISC should review annually. The DCISC should also review the results of the Generation Vulnerability Investigation Team report following its release in June 2001. 4.11 The Equipment Qualification Program appeared to be functioning well with no significant outstanding issues. The DCISC Team reviewed several engineering programs at this fact-finding meeting as discussed above and decided to try to review all engineering programs together in a single fact finding meeting in the future.

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate specific safety matters for the DCISC. The objective of the safety matter review was to determine if PG&E's performance in these areas is appropriate and if any of these are important enough to warrant further review, follow-up, or presentation at a public meeting. These safety matters include follow-up and/or continuing review efforts by the Committee, as well as those identified as a result of reviews of various safety related documents. 3.0 DISCUSSION 3.1 DCPP Communications Update The DCISC Fact-Finding Team met with Jeff Lewis, DCPP Public Relations, to discuss recent communications with the public. The NRC recently had a public news conference in San Luis Obispo to address the possibility of safety issues as a result of PG&E's financial problems. Mr. Lewis stated that the NRC told the public that PG&E continues to allocate enough money to run Diablo Canyon properly and has shown no sign of compromising safety. The NRC said that they have had more NRC staff visits to the plant, in addition to the regular on site inspectors. There were two TV stations, one newspaper and two radio reporters, but few members of the public, at the news conference. PG&E participated in a public meeting hosted by the County Supervisor to discuss the Dry Cask Storage Facility for DCPP spent fuel. There was a large public turnout for this meeting. PG&E continues to meet with the public to keep them informed about the Dry Cask Storage Project. PG&E had a TV station out to Diablo Canyon to cover the new fuel shipment and handling for 2R10. Mr. Lewis stated that the San Luis Obispo Mothers For Peace have said that Diablo Canyon is necessary because of the California energy situation. Most of the Public information about the PG&E bankruptcy has been handled out of PG&E San Francisco office.
== Conclusion:== It appears that PG&E is doing a good job of keeping the public informed about Diablo Canyon and PG&E items of interest. D. 7-2
Survey 3.2 Results of December 2000 Culture Team met with Rich Cheney, The DCISC Fact-Finding Program (ECP), to review the Supervisor of Employee Concerns (CCA) Cultural Assessment results of the 2000 Comprehensive 2000 on the plant that was conducted in November/December, included 40 employee wide safety culture. The assessment to provide a comparison to interviews. The survey was designed been conducted in 1998. the previous survey, which had was conducted in The first plant-wide safety culture survey at Fact-Finding Meetings and 1998, and was reviewed by DCISC a limited survey was conducted at a Public Meeting. In 1999, within the plant and was reviewed for selected organizations Meeting. The response to the by the DCISC at a Fact-Finding improved over the 1998 survey 2000 survey by the employees (80.4 % Vs 62%). and analyzed the survey, SYNERGY, the company that designed other of the DCPP survey to 12 also compared the results their database to provide an industry nuclear plants in are directly from the ranking.

- Corrective Action Process (ARs) - Problem Identification NSC had three areas of relative weakness:
- Employee confidence in decisions on allocation of resources (adequate staffing, experience, and qualifications) to assure nuclear safety is maintained.
- Confidence in & Effectiveness of the ECP
- Timeliness and Overall Effectiveness of the AR Process.
The summary of results for the SCWE showed that employee willingness to take appropriate action at DCPP is in the "very good to excellent" range, and that the environment at DCPP for raising potential nuclear safety issues or quality concerns is "very good". SCWE "Indicators & Precursors" rating for Management and Supervision improved by 12% and 8% respectively for the DCPP site composite. For the four individual organizations with the relatively lowest SCWE rating in 1998, the average rating of SCWE "Indicators & Precursors" for Management and Supervision in 2000 improved by 25% and 14% respectively. The organization with the lowest SCWE rating in 1998 and 2000, showed improvement in SCWE "Indicators & Precursors" ratings for Management and Supervision of 12% and 3% respectively. The summary of results of the progress on effectiveness of the ECP is as follows:
"* The DCPP site composite rating of the overall effectiveness of the ECP improved by 4%. "* For the five individual organizations with relatively lowest ECP ratings in 1998, three showed improvement (+
7% to + 26%), one showed no change and one declined ( 6%).
"* Rating in Chemistry also declined (- 11%).
The effectiveness of the ECP was rated lower than NSC and SCWE and given the lowest rating of all by Operations. D.7-4

Conclusion:
The results of for DCPP with improvements Survey appear to have been positive the results of in all but a few areas. PG&E has communicated an action plan the survey to all employees and is developing D.7-5
to address areas that need improvement. The DCISC should review the action plan and monitor its implementation. Recommendation: PG&E should identify and take action to improve the employees' perception of the Employee Concerns Program. 3.3 Results of INPO Evaluation PG&E reviewed the results of the recent INPO evaluation. This was the eighth INPO evaluation of DCPP. DCISC has reviewed these evaluations at previous Fact-Finding meetings. INPO identified 10 strengths and 11 areas for improvement, with no repeat areas for improvement. DCPP had performed a pre-INPO self-assessment and identified most of the same areas for improvement. They let INPO review this self-assessment. INPO also reviewed 6 operator training programs for accreditation. PG&E will meet with the INPO accreditation board in June, 2001 to get the results of these programs. INPO will review the other 6 training programs with the next DCPP evaluation. The detailed results of the INPO evaluation were reviewed but are not presented here, as they are proprietary between INPO and the Utility.
== Conclusion:== The results of the recent INPO evaluation of DCPP appear to be very favorable. DCPP continues to receive very good reports from INPO. 3.4 Tracking Data Concerning the Accredited Training & Instructor Training Programs M. Peraky, Maintenance Training Instructor and R. Snyder, Chemistry/Radiation Training Instructor discussed the various means that are used to track data concerning the accredited training and instructor training programs. There is a Senior Management Oversight Training Committee and each group has an oversight training committee. These committees meet quarterly or more often if necessary to review the status of performance, problems and actions taken for each of the accredited training programs. D.7-6

Type of participation is defined as assessor or peer evaluator. The performance plans were reviewed for the Instructor Training Program, Technical Maintenance, Mechanical Maintenance and Chemistry/Radiation Protection.
== Conclusion:== It appears that the method DCPP has for tracking the performance of the accredited training & instructor training programs is effective and involves both the training and line organizations. The DCISC should review the Performance Plan Review for the remaining accredited training programs in the fall of 2001 and all of the Performance Plan Reviews in 2002 to determine the status of the improvements that DCPP identifies. 3.5 Update on Self-Assessments S. Hiett, Self-Assessment coordinator, presented an update on the DCPP self-assessment program. DCISC has reviewed this program at previous fact finding meetings and Public Meetings. The current Self-Assessment Program was started at DCPP in late 1999. They stated that the program is doing very well, but still can be improved. The program should reach maturity by the end of 2001. The managers are continually encouraged to improve on their self-assessments. DCPP performed 55 self assessments during 2000. They have set a goal of about 40 self-assessments per year by the line organizations and have met or exceeded these goals. Overall, they have produced a large number of quality reports. DCPP asked INPO to provide report writing assistance. DCPP has generated 15 reports in the first quarter of 2001, but it is felt that the quality of some of the reports has declined. They are working with other STARS plants on self-assessments to perform round-robin assessments between plants and share resources. D. 7-8

3.7 Status & Plan for Dry Cask Storage of Spent Fuel The spent fuel storage facility for DCPP was reviewed at the DCISC fact-finding meeting on November 14 & 15, 2000. The purpose of this discussion was to an update on the project. J. Strickland, Project Manager of the Used Fuel Storage Project, presented the overall status of the project. PG&E believes the project is going very well. They are close to making the goal for filing the license application on April 13, 2001 but have not filed yet. However, the NRC Project Manager wants assurance that the License Application includes all information needed by the NRC for review, including the calculations that PG&E was going to submit 30 days later. DCPP will now submit the application around June 1, 2001. Holtec International (dry cask storage system vendor) is also in the process of revising their license. The NRC will review the site submittal first and then review PG&E calculations when Holtec submits their information. PG&E described the detailed design of the storage facility and the location at the site. The PG&E presentation at the DCISC June, 2001 Public Meeting and the presentation to DCPP Plant Safety Review Committee (PSRC) was also discussed. The presentation to the DCPP PSRC included:
- Overview
- Application Scope
- NRC Regulatory Guidance
- Other Utility Submittals
- License Approach
- Review Process
- Safety Analysis Report
- Accidents Analyzed
- Fires and Explosions
- Tower Collapse
- Transmission Line Strike
- Engineering Status
- Conclusions (No significant hazards considerations)
There will be a final PSRC review before the license application is filed with the NRC. PG&E will have future public meetings to answer any questions.

Their future plans call for evaluating the priority of the next PRA-AOT application for the second half of 2001 (diesel generators or one ECCS SSC) . The development of a Shutdown & Transition model has been deferred to 2002.
== Conclusion:== It appears that DCPP has been successful in staffing and developing the PRA Group at the site. The PRA Group is also supportive of daily plant activities and has prepared themselves to work in the new NRC risk-informed era. 3.9 Generation Vulnerability Identification Team Aging Management has been a topic of discussion at many fact-finding meetings and Public Meetings. The program has not been progressing as PG&E had originally planned. Ken Bych, PRA Supervisor, discussed with the DCISC team what DCPP is doing in the area of aging management. DCPP has had seven or eight aging related failures of equipment in the last year that impacted outages, generation or forced outages. All were caused by balance of plant equipment. The Integrated Problem Response Team (IPRT) approach was sanctioned by the DCPP Management Team to address the lost generation. DCPP established a Generation Vulnerability Identification Team (GVIT) in late 2000 consisting of 12 members and sponsored by the Director of Engineering and Maintenance. The original scope of the work was:
"* Focused on identifying potential generation losses from equipment failures that can exceed one full day of generation, or a greater than 10% derate for more than one day. "* Enhance/create a process for longer-term reliability or aging management issues that merit funding. "* Provide recommendations and solutions to management on resources, tools, and process changes.
This will be phase one. They will make a decision about aging management after completion of recommendations based on phase one. The majority of the work has been completed, and the final report will be out by June 30, 2001. D. 7-12

Conclusion:
By making nuclear safety the highest priority, it appears that DCPP continues to stress the proper priorities to the operating crews and is working on improving professionalism in the control room. 3.11 Security Response/Reaction to QA Security Audit Ron Todaro, Security Services Manager, reviewed with the DCISC Team the Security response to the NQS audit of Security. NQS recommends that Security use the Plant Quality Program to identify and correct problems. Security has agreed to two other NQS-recommended changes:
- 1. Issues dealing with Equipment Problems - Security will now write ARs on all equipment problems and use a trending program.
- 2. Issues dealing with people, process & procedures Security has not been using root cause analysis on all of the low-level events. Security will set certain threshold levels at which they will write ARs, but will not write them for every logged event. They will do trending on all the logged events.
NQS recommends that Security eliminate the Security Review Group process and utilize plant corrective action programs with NCRs and QEs as applicable. Security is working with NQS on this matter, but has not agreed to it at this time. The Security Manager also discussed NRC developments in the Security Area. The Utility Security Working Group is working with NEI to resolve these issues with the NRC.
== Conclusion:== It appears that Security has been responsive to most of Nuclear Quality Service's (NQS) audit recommendations and is working with NQS to settle the final remaining issue. DCISC will follow up on these issues at a future fact-finding meeting. D. 7-14

Recommendation: It is recommended that DCPP System Engineering develop a plan for how these reports should be utilized by Operations and Maintenance. 3.13 Discussion with Manager, Radiation Protection The DCISC Team met with Bob Hite, Manager Radiation Protection, for an informal discussion of the activities of the Radiation Protection Group. Mr. Hite reviewed the performance of the Radiation Protection program before, during and after IR10. The staff of the Radiation Protection Dept. works with the outage planners and persons responsible for detailed planning of tasks prior to the outage. The DCISC Fact-Finding Team was favorably impressed with Mr. Hite's discussions. The meeting was during an informal lunch, and the discussions were very open and relaxed. Mr. Hite has years of experience working with ALARA and understands how it can be a useful tool. He recognizes that good planning and scheduling are important in achieving low collective doses. Careful review of task plans provides assurance that individuals are not subjected to exposures that approach regulatory limits. Several steps have been taken to reduce personnel exposure. Meetings or discussions that do not need to be in containment are scheduled to be held outside containment. Plans are reviewed to minimize the number of changes of protective clothing. This reduces risks of contamination and can reduce costs. The chemical treatment of cooling water that the plant has adopted again demonstrated that background radiation can be reduced in the plant. The DCISC Team Member inquired about the way collective dose numbers are now used as a Performance Indicator. This follows up on earlier discussions. Based on this Fact-Finding Meeting, the DCISC recommends that we schedule a future discussion of the use of collective dose as one of the major nuclear power plant performance indicators.
== Conclusion:== It appears that the DCPP Radiation Protection Group is performing very well with the ALARA Program to plan and schedule work to obtain low radiation dose. The DCISC should schedule some time for a future discussion of the use of collective dose as one of the major nuclear power plant D. 7-16

audited organizations, and 3) audit scopes were comprehensive and covered regulatory requirements. The role of the NSOC in selecting the scope of the NQS independent audit was also discussed. NSOC reviews the scope of these audits after NQS determines the scope, but has had little input into the process. The DCISC stated that they thought that NSOC should take a more active role in determining the scope of the annual audit of NQS to give the audit more independence.
== Conclusion:== It appears that NQS is performing Self Assessments in a timely manner and the scope of the audits seems to be satisfactory. Recommendation: It is recommended that NSOC take a more active role in determining the scope of the audit of NQS to give the audit more independence.
4.0 CONCLUSION
S 4.1 It appears that PG&E is doing a good job of keeping the public informed about Diablo Canyon and PG&E items of interest. 4.2 The results of the 2000 Synergy Safety Culture Survey appear to have been positive for DCPP with improvements in all but a few areas. PG&E has communicated the results of the survey to all employees and is developing an action plan to address areas that need improvement. The DCISC should review the action plan and monitor its implementation. 4.3 The results of the recent INPO evaluation of DCPP appear to be very favorable. DCPP continues to receive very good reports from INPO. 4.4 It appears that the method DCPP has for tracking the performance of the accredited training & instructor training programs is effective and involves both the training and line organizations. The DCISC should review the Performance Plan Review for the remaining accredited training programs in the fall of 2001 and all of the Performance Plan Reviews in 2002 to determine the status of the improvements that DCPP identifies. 4.5 It appears that DCPP has the self-assessment program well D.7-18

2.0 INTRODUCTION
This fact finding trip to the DCPP was made to evaluate DCISC. The objective of the specific safety matters for the if PG&E's performance in safety matter review was to determine any of these areas revealed these areas is appropriate and if enough to warrant further observations which are important at a public meeting.

3.0 DISCUSSION 3.1 Changes in Radiation Protection Philosophy and Organization The DCISC Fact-finding Team met with Bob Hite, Manager of Radiation Protection. The DCISC first met with Mr. Hite in October 2000 (Reference 6.1), shortly after he joined PG&E at DCPP. The purpose of this discussion was to review changes to the DCPP Radiation Protection (RP) philosophy and organization which Mr. Hite had made. Mr. Hite reported the following current organizational structure issues:
"* Diffuse supervisory accountability - there were too many direct reports to some supervisors (e.g., the General Foreman) "* Rad Engineers (individual contributors) report directly to the Manager of RP "* Rad Engineers not organizationally tied to plant process teams and production goals "* High Impact Teams had been set up to follow processes but cross supervisory boundaries These issues and loosely defined program roles were leading to overlaps and knowledge disconnects between personnel in field implementation.
Future structure goals include:
"* Process-based organization aligned with Operations and Maintenance organizations "* Supervisory accountability for process ownership "* Clearly-defined, non-overlapping roles and responsibilities tied to Asset Teams such as "* Radwaste/Decon "* Maintenance Asset Team Support "* Operations Support "* RP Programs Support "* Improved RP planning, e.g., Maintenance planning model and a full-time outage RP planner to help reduce dependency on contractors. "* Implement new structure following Outage 2R10 D. 8-2

Conclusion:
DCPP has had what appeared Program, Radiation Protection (RP) past to be an acceptable than doses have been higher although cumulative radiation abnormally-high industry averages. This was partly due to programmatic and 1R9. The planned radiation levels in Outage the promising in improving RP at organizational changes appear to follow DCPP RP results. station. The DCISC will continue for Outage 2R10 3.2 Radiation Protection Planning RP plans for upcoming Outage The DCISC Team discussed plans, there 2R10 with Mr. Hite. In addition to the normal were the following changes: Posting - previous signs Simplified Radiological too Areas (HRAs) were identifying High Radiation was not standardized and confusing because the layout and labels.

- 3. Radiation dose rates (R) is color-coded for quick Each of these "C.A.R." labels color-coding and understanding. The identification scheme is as follows:
0 Green: no significant radiation hazard exists D. 8-3
"* Yellow: the area has radiation levels, which require special clothing, or instructions - check these or contact RP. "* Red: the area has radiation levels requiring RP support. "* Work briefings moved outside of Containment - previous in-Containment briefings were adding to doses, and moving them to low-dose areas will help to lower doses.
- Hot Particle Control emphasis changed - the previous high emphasis on Hot Particle Control was changed to overall Contamination Control, which includes all radioactive contamination.
"* Improvements in protective clothing footwear - a change from the integral nylon/rubber bootie to a separate nylon bootie and rubber overshoe will be safer on slippery surfaces and will help reduce contaminations.
== Conclusion:== In addition to the normal Radiation protection planning for Outage 2R10, DCPP has made what appear to be simple, logical and effective changes to radiological postings, lower-dose work planning locations, contamination control, and protective clothing. 3.3 Radiation Control Area Tour The DCISC Team toured portions of the DCPP Radiation Control Area (RCA) with Mr. Bob Hite. The purpose of the tour was to observe existing and improved radiation area controls. The tour included the following areas:
"* Steam Generator (SG) Outage Primary Telemetry & Remote Dose Monitoring Facility - a mobile office with equipment to remotely monitor SG inspection activities and related radiation fields. "* 140-foot elevation Unit 2 Containment RCA Access Control - main access control point for ingress and egress to the Containment. "* 85-foot elevation RCA Auxiliary Building Access Control Point - main access control point for ingress and egress to the Auxiliary building. The group was processed in and out of the RCA here, including logging into the RCA access control system, receiving D. 8-4
and RP instructions, receiving alarming dosimeters, screening upon receiving hand and foot radiological exiting. DCPP had added dosimetry-system-controlled entering the RCA turnstiles to prevent personnel from system. without properly logging into the Penetration Room

at onsite and offsite locations within a 50-mile radius of DCPP. These programs have been adapted to the unusually complex terrain surrounding DCPP, e.g., ocean, land and mountains. The programs have been verified by dye tests and have performed well in emergency exercises. The results of the calculations in the programs are used to recommend protective action levels (PALs) to San Luis Obispo County to advise the public regarding sheltering and/or evacuation following a plant event. DCPP has been pleased with the performance of EARS and MIDAS. Lempke reported that EARS and MIDAS are being upgraded to a Windows format for more ease of use. DCPP is also adding an off-line version to be used in training.
== Conclusion:== DCPP is satisfied with the programs for calculating dose projections during emergency situations and is upgrading them for more ease of use. 3.5 Communicating Radiological Information to the Public Mr. Lempke reviewed improvements to communications with the public concerning radiological information. DCPP had some problems with conveying accurate information to the public during its May 2000 unusual event (Reference 6.3) and during the May 10, 2000 emergency exercise (Reference 6.4). The unusual event included a fire which caused the plant to shut down, utilizing its main steam safety relief valves to relieve steam pressure. The NRC had made a news statement that radioactive steam had been released, resulting in confusion about what constituted a radiological "release" above and beyond normal approved releases. The problems in the emergency exercise occurred at the mock public/news media briefing at the Joint Media Center. The county and PG&E plant spokespersons did not provide readily understandable radiological information for the public regarding calculated/actual dose levels and their effects and information on sheltering. Mr. Lempke stated that DCPP was working on the definition of a radiological "release" specifically attributable to an event. NRC is also working on their definition. DCPP is selecting the appropriately skilled persons with radiological knowledge to be added in the EOF. Such a person will hear first-hand plant D.8-6

results of the plant-wide safety culture assessment. An earlier DCISC fact-finding team conducted a more in-depth review in April 2001 (Reference 6.6). The first plant-wide culture survey was conducted in 1998, and the DCISC reviewed its results at its January 21-22, 1999 Fact-finding meeting (Reference 6.7) and its January 28-29, 1999 Public Meeting (Reference 6.8). In 1999 selected organizations were surveyed. The 2000 survey response rate was improved over the 1998 survey (80.4% vs. 62%). Synergy, the company designing and analyzing the results, compared the results to 12 other plants' surveys to provide an industry ranking. The following overall results were reported: "* Overall, the DCPP nuclear safety culture (NSC) was rated "good to very good" and was perceived as having improved (+6%) since the 1998 survey. "* The safety conscious work environment was rated "very good to excellent" and was perceived to have improved notably (+7%). "* The Employee Concerns Program (ECP) was rated "adequate to good" and was perceived to have improved moderately (+4%). It was noted that seven of the eight previous "targeted organizations" (Fire, Safety & Health; NSSS Maintenance; Radiation Protection; NSSS System Engineering; Security Services; General Services; and Technical Support Engineering) showed significant (>10%) or notable (>5%) improvement. One of the eight, Shift Operations, remained steady, except for a decline in the Employee Concerns Program rating. The decline was likely due to lingering concerns about the Operations Shift Foreman who was removed from service in 1998, specifically due to issues related to his employee concerns and to the related Department of Labor report. More detailed results (i.e., for specific functional organizations and more specific areas of review) were reported; however, these have been reported in the previous DCISC fact-finding report (Reference 6.6). PG&E's action plans following the survey are as follows:
- Develop an action plan and communications schedule with the Culture Steering Team and management D.8-10

"* Communicate the results management action plans to employees "* Communicate the results and via e-mail and site-wide meetings will hold section-wide "* Following Outage 2R10, Managers and section action plans meetings to discuss results asked if there were a correlation The DCISC fact-finding team survey results and INPO ratings.

- 2. Bankruptcy Impact - DCPP considers the bankruptcy "business as usual" regarding plant operations and management. The plant has its full 2001 authorized budget and expects the same in 2002. The only issue has been a potential short supply of some supplies, such as nitrogen gas. Management provides daily and weekly communications within the plant to keep employees current. There are weekly updates for the NRC, and there have been no adverse safety effects. There had been pressure from the Governor's office to not reduce power during ocean storms; however, PG&E will follow their procedures to reduce power when necessary to maintain plant safety. DCPP has analyzed the 230kV offsite emergency power source and believes it is adequate.
- 3. NSOC Re-organization - Larry Womack discussed potential re organization of NSOC. They were reviewing whether to continue the Humboldt Bay Subcommittee due to the nuclear fuel being removed and stored in dry cask storage but have not reached a decision. The Oversight and Corrective Action Subcommittee would remain. Human Performance and Equipment Performance are up for consideration and discussion.
Most significantly, STARS will have a Nuclear Safety Review Board initiative team which Mr. Womack will lead. The STARS Team will review the regulatory compliance requirements to attempt to eliminate the requirement for the Presidenmt's Nuclear Advisory Committee (PNAC) and NSOC but retain the function and combine resources for STARS plants. The retained function would include human performance, corrective action, operational reliability/review, etc. He would hope to shift emphasis away from reviews of IOCFR50.59 documents, NRC inspection reports, etc. to more operational improvements. Mr. Womack anticipates having a proposal for the STARS Chief Nuclear Officers in about six months but maintain the status quo for one year. (The DCISC Team decided to ask Mr. Womack to discuss these plans in the upcoming June Public Meeting).
- 4. Corrective Action Oversight and Assessment Subcommittee Jack Martin and Jim Tompkins reviewed the following items for this new NSOC subcommittee:

An outside Member stated that the plant needed to lower human errors through trending, cause-code analysis and benchmarking. Mr. Womack agreed, stating that more focus is needed on low-level errors, which can lead to significant errors. (The DCISC should follow this item). B. Plant Staff Review Committee Summary There was nothing significant to report. C. Safety Evaluations There were no significant problems. Safety evaluation reviews indicated that the quality of some Licensing Basis Impact Evaluations (LBIEs) had degraded in that they needed amplifying/clarifying comments as a basis for answers.

- 9. Human Performance Jim Becker, Station Manager, provided an update on human performance. Based on analysis of error causes, the Human Performance Steering Committee (HPSC) believed that there were three key behaviors, which would have prevented many human errors at DCPP. These were (1) 3-way communication, (2) effective tailboards, and (3) self-verification. This was substantiated by INPO.
Human performance error rate showed improvement in early 2000 but has degraded beginning in third quarter 2000. There have been four recent Event-Free Day "clock resets" due to a more frequent error rate. Lack of proper self verification has been the primary cause of human error. A self-assessment was conducted in March 2001 with an interdisciplinary team and an industry expert. Recommendations included the following:
"* Strengthen management observations "* Standardize/define behaviors (typically the 3 behaviors: 3-way communication, effective tailboards, and self-verification. "* Reinforce the Personnel Accountability Model "* Stay the course The HPSC established a one-year plan with the following aspects: "* Augmented human performance training for Operations, Maintenance, Radiation Protection and Engineering "* Goal-setting "* Self-assessment "* Communications "* Observations "* Rewards for successful Event-Free Days NSOC agreed that these were the correct actions, and they were high priority.

== Conclusion:== The May 2, 2001 Nuclear Safety Oversight Committee (NSOC) meeting included discussion on significant plant issues, in particular the integration of human performance, corrective action, self-assessments, and management observations to effectively solve chronic plant problems. Discussion was straightforward, actions were assigned, and many suggestions were helpful; however, there were limited challenges to existing thinking and processes. The DCISC should continue to follow NSOC activities and monitor the planned changes over the next year. Recommendation: The DCISC should recommend to PG&E that both internal and external Nuclear Safety Oversight Committee members express higher expectations of DCPP and take a more aggressive stance in challenging problem-solving and the status quo.
4.0 CONCLUSION
S 4.1 DCPP has had what appeared to the DCISC in the past to be an acceptable Radiation Protection (RP) Program, although cumulative radiation doses have been higher than industry averages. This was partly due to abnormally high radiation levels in Outage 1R9. The planned programmatic and organizational changes appear promising in improving RP at the station. The DCISC will continue to follow DCPP RP results. 4.2 In addition to the normal Radiation protection planning for Outage 2R10, DCPP has made what appear to be simple, logical and effective changes to radiological postings, lower dose work planning locations, contamination control, and protective clothing. 4.3 It appeared to the DCISC team touring the DCPP Radiation Control Area that effective use was being made of radiological posting, monitoring, and controls. 4.4 DCPP is satisfied with the programs for calculating dose projections during emergency situations and is upgrading them for more ease of use.

3.0 DISCUSSION 3.1 Human Performance Update The DSISC team met with Al Jorgenson and Lance Sawyer of the HP department, following up on the visit in December 2000 (Reference 6.1). The error rate trend was downward, with the highest levels appearing in the middle in both outages. This higher rate is a common trend in other plants, as well, because of the type of work during outages. Operations' rate was highest, because their activity rate goes up by 5-10 times in an outage, with additional equipment in use and the increased number of clearances. Also, because of licensing requirements, operations cannot augment their number with contractors. "Unknown" errors are attributed to Operations. Investigation and review of procedures is then carried out, but without focus on individual culpability and discipline. The engineering error rate appears relatively low, since latent errors from outages show up only later. At that time, they are re-attributed to their actual date. During the May 2R10 outage, the overall error rate was 0.9 errors per 100,000 work-hours, which is the desired 12 month average. The cumulative error count was lower than that of the last 2 outages, likely due to more lab simulations being performed in advance. This included classroom work with maintenance mock-ups, providing an opportunity to practice and become familiar with equipment and procedures, and to anticipate possible error situations. The overall HP plan includes establishment of a program looking at human factors that may be affecting performance. The Safety Committee had received an inquiry from an operator at another plant regarding DCPP's policy on operators' taking naps during a shift. When asked about this, the HP presenters responded that PG&E policy "OPl.DCl2, Conduct of Routine Operations," recognizes the need for activities that enhance alertness, such as a nutrition or exercise breaks, a rest period, or taking a shower. Two thirty-minute breaks per 12 hr shift are allowed, as long as there is adequate coverage while the operator is D. 9-2

By consultant for mutual there is already a basis employees and craft-led, the plant, and an understanding of issues specific to trust, D.9-3
an opportunity for the program to be better tailored to both the needs of the workers, and of the plant as a whole. Each 20-minute observation utilizes the observation checklist, which looks at the following in terms of safety vs at-risk behaviors:
- 1. Work Control Area
- 2. Protective equipment
- 3. Ergonomics
- 4. Tools and equipment
- 5. Safety at heights Then direct feedback is given, one-on-one, in a non-blaming manner, including the specific safety concern and how it could be remedied.
Results:
- 1. Increase in personal protective equipment use, due to increased enforcemeht and greater availability, especially for those needing to be tailored to individual requirements, as with prescription safety glasses, or with flash suits and booties, now available in a full array of sizes.
- 2. With the aging work force, increased vulnerability to injury becomes an issue, with risk factors that include slower reaction time, decreased flexibility, and longer healing time for injuries. As a result, precautionary measures have been implemented. For example, emphasis is placed on body positioning, and on flex-and-stretch exercises for employees before crawling into cramped areas.
- 3. During the recent outage, the safety report data correlated well with minor injury reports (pink slips) produced by BOBS.
As a result, they are now working on refining the process and reinforcing it.
- 4. Motivation is high, with the workers actually gaining a passion for safety, with resulting increased savings and efficiency. There is an increased sense of control and empowerment, contributing to increased individual and "community" responsibility, and an increase in morale.
- 5. The program has helped increase safety awareness at all levels, and is supported by the overall culture. Rather than being left to the supervisor, the safety culture is pushed D. 9-4

meetings, and trainings in San Francisco. Despite the energy crisis, overall morale is stable. Their job duties include:
- 1. Teaching the monthly behavior observation class
- 2. Monitoring the Fitness for Duty (FFD) program with referrals and follow-up. This consists of follow-up on positive testing and alcohol DUIs. Drug detection is trending down, and the vast majority of cases are alcohol related. FFD statistics for 2001 were not available.
- 3. Counseling for job-related issues, referring for other problems to local therapists and psychiatrists. They can immediately authorize up to 10 visits without having to go through other channels of authority, a boon to the employees, who are then able to get help without delay.
- 4. EAP plans on doing more team counseling for co-workers and teams to prevent or mediate conflicts, and enhance communication. They would also like to offer more classes with specific focus, and sponsor affinity groups (e.g., aging parents, parents of teenagers) allowing the employees to share information and resources.
EAP supplies two quarterly publications, published under contract by Value Options, one for the entire plant and one geared to supervisors. The current issue had two lengthy and thorough articles "How to Handle Workplace Bullies" and "Sleepless Nights - Wasted Days." The former describes bullying behavior, tips on coping, and suggestions for further reading. The sleep article addressed the importance of adequate sleep for maintaining alertness, productivity, mood, and overall health, and the vicious cycle of stress and insomnia. It describes symptoms of sleep deprivation, and gives remedial techniques to deal with insomnia. One useful quote is "inadequate sleep even as little as one or two hours less than usual, can greatly exaggerate the tendency for error during the vulnerable time periods," that is, between 2 p.m. and 5 p.m. and between 2 a.m. and 5 a.m. The article describes the association between poor eating habits and daytime drowsiness, and gives suggestions for D. 9-6

4.0 CONCLUSION
S 4.1 The Human Performance Program is doing an adequate job of error trending, evaluating the data, and working toward increasing performance and enhancing safety. 4.2 The Behavioral Observation Based Safety Process appears to provide a major cultural change, and provides a positive force in increasing work safety. Moreover, even though its focus is on safety, it is teaching craft many of the concepts and skills involved in the "We culture", with resulting impact in other areas such as communication. It is an excellent way of enrolling craft in the "We Culture" not just from the top down but from the bottom up. 4.3 The transition to "Process" instead of "Function" is progressing. A specific work process review should be done in a future fact finding. 4.4 EAP appears to be well-utilized, and is carrying out its responsibilities appropriately. The DCISC should follow up on statistics in a future fact-finding meeting. 4.5 Operator fitness continues to be an issue of concern, and the DCISC should continue to track the issue. 5.0 RECOMMENDATIONS There are no recommendations for PG&E in this report.

This program includes significant (Exhibit B.6) plant systems training and cross-discipline technical training. Both training elements were developed using INPO's Systematic Approach to Training to assure the areas needing attention were fully addressed, based on an assessment of the knowledge and existing skills of the ATLs. Program implementation started in early 2000. Plant Systems classes and the first phase of the 3-phase cross-discipline technical training are complete. The two remaining phases will be completed by the first quarter of 2001. Following the specific training program described above, routine continuing/refresher training will be implemented in accordance with the established Maintenance Supervisor Training (MST) Program. The MST Steering Committee (composed of the Manager, Maintenance Services, an Asset Team Leader, ATLs and Learning Services) will continue to address any new training issues identified for the ATLS. In addition to the discipline technical training described above, ATLs are required to complete management development courses. In 2000, the course topics included conducting a Collaborative Performance Review and Correcting Performance Problems. Topics being planned for the upcoming year include Coaching, Giving and Receiving Feedback, and Building Trust. L ___________________ L _________

This steering committee has mandated that departmental committees be established which February 2001 DCISC report to the steering committee on a regular Public Meeting basis. One of the key objectives of the HPSC (Exhibit B.6) is the development of a common philosophy and strategy for human performance improvement ensuring the objectives are linked to NPG's overall operational plan. The formation of an executive steering committee will ensure the various initiatives undertaken by individual organizations within NPG will be well coordinated and adhere to a common philosophy while striving for common goals and values.

To ensure that this alertness on shift to further valuable information is provided to the February 2001 DCISC improve operator human operators, classes from this program tailored Public Meeting performance. (4.9.3) to shift work will also be presented to the (Exhibit B.6) operating crews in one-hour sessions every other five-week training cycle. To enhance physical fitness and mental alertness on-shift, several actions are being considered, including providing additional break time for on watch-licensed operators and encouraging use of the fitness facility during breaks. The DCPP medical staff is also further evaluating its operator fitness levels.

Although the crew immediately noted (Exhibit B.6) fact the indications of increased steam flow and finding. aggressively pursued determination that an MSSV had lifted, they performed several activities, including shift turnover, prior to taking actions to reseat the valve. The following actions were taken to address this issue: Simulator Instructors are now emphasizing the importance of proper prioritization of emergency action in tailboards and critiques. The Operations Superintendent has personally observed and reinforced crew
awareness of this issue.
" Emergency Procedure E-0, "Safety Injection or Reactor Trip Response,"
was revised to allow for quicker completion of high priority diagnostic steps. This change, which allows lower priority equipment checks to be done in parallel with the diagnostics section of the procedure, results In earlier diagnosis of events.
" A special simulator training scenario was developed as an exercise to reinforce operator understanding of emergency operating procedure (EOP) bases. In this scenario, the operating crew responds to an event without the use of the associated EOP procedure set. The scenario requires that operators use their knowledge of EOP bases to set priorities without the aid of procedures. Similar training scenarios at other nuclear stations have been shown to improve operators' understanding of procedure bases and, thus, the associated procedure priorities.
In addition to the above, the importance of discussing priorities during event response tailboards (Including the Identification of the highest priority) has been emphasized to the operating crews. Since the December 1998 Unit 2 reactor trip, no cases have been noted in which operators pursued lower priority activities during event responses at the expense of monitoring and controlling critical plant parameters. 151 It is recommended that NQS ROO-10 PG&E agrees with the recommendation.

It is noted that each of the problems alluded to by the DCISC were self identified through the above review activities and programs. The DCPP problem identification and resolution process requires that all problems identified during the normal course of business, including design issues, be documented and resolved in accordance with the CAP. Although an additional Civil Engineering design review is not considered warranted, PG&E will ensure that any design problems that are identified are appropriately addressed in our CAP, including the consideration of potential generic implications.

Exhibit J GLOSSARY OF TERMS AND DEFINITIONS Aging Management is a program for monitoring and dispositioning materials and components whose characteristics change with time or use. PG&E defines aging management as "Engineering, operations, and maintenance activities to control age-related structures, or degradation and to mitigate failures of systems, components (SSC) that are due to aging mechanisms." As Low As reasonably Achievable (ALARA) refers to maintaining offsite radioactive releases and occupational radiation exposures as low as achievable in a reasonable, cost-effective manner. Capacity Factor is the fraction of power actually produced at compared to the maximum which could be produced by operating full power during a period of time (expressed in percent). Civil Penalty is a penalty in the form of a monetary fine levied by the Nuclear Regulatory Commission for a significant violation of its regulations. Control Rods are long slender metal-clad rods which move into or out-of nuclear fuel assemblies in the reactor core to control the rate of the nuclear fission process. The rods contain a neutron absorbing material which, when inserted into the fuel, absorb neutrons, slowing down the fission rate and thus the heat generation rate and reducing the power level of the reactor. Design Basis are the current features and criteria upon which the nuclear plant is designed and are also the bases for Nuclear Regulatory Commission review and approval. Diesel Generator (DG) is a standby source of emergency electrical power needed to power pumps and valves to provide cooling water to the fuel in the reactor to prevent its overheating and possible melting. The diesel generator is normal designed to start up and provide power automatically if power is lost. Emergency Operations Center (EOC) is the facility away from the immediate vicinity of the plant which is used to direct the operations for mitigation of and recovery from an accident. Emergency Preparedness (EP) is the assurance that the plant and its personnel are practiced and prepared for postulated J-1

(FSAR) is the document which Final Safety Analysis Report and operations for describes the plant design, safety analysis, approval for licensing Nuclear Regulatory Commission review and for plant operation. Fitness for Duty (FFD) describes the state of an employee in sound enough (cleared to access the nuclear plant) being and safely carry physical and mental condition to adequately out his or her duties without adverse effects. High Impact Team (HIT) is a term denoting a multi-disciplinary or multi-functional team of people put together to focus on solving a particular problem or perform a particular task. The included are those necessary to effectively disciplines accomplish the task. waste, usually in High Level Waste (HLW) is highly radioactive been discharged from the form of spent fuel (or fuel which has level (as defined by the reactor as waste) containing a high HLW is NRC regulations) of radioactive fission products. using water or a thick container as a handled remotely, radiation shield. level 2 Probabilistic Individual Plant Examination (IPE) is a accident sequences. The Risk Assessment (PRA) analysis of plant through the release analysis includes core damage progression and the subsequent of radioactive material to the containment potential of determining containment failure but stops short J-2
impact on the public or property. The NRC requested all nuclear plants be analyzed in this way to get a better understanding of severe accident behavior. An IPEEE is an IPE which is initiated by External Events to the plant. INPO, the Institute of Nuclear Power Operators is a nuclear industry group formed after the Three Mile Island accident to help improve nuclear plant operations through regular assessments of each nuclear plant, evaluations, best practices, and nuclear operator training accreditation. Inservice Inspection (ISI) and Inservice Testing (IST) are the practices of inspecting and testing certain selected components periodically during their service lives to determine degradation patterns and to repair, if necessary, any degradation beyond acceptable limits. Licensee Event Reports (LERs) are reports from the plant operator to the Nuclear Regulatory Commission describing off normal events or conditions outside established limits at a nuclear plant. Loss of Offsite Power (LOOP) is an occurrence whereby the normal supply of electrical power from offsite is interrupted. Nuclear reactors need power from offsite when shutdown for spent fuel cooling and residual heat removal. There are usually several sources of offsite power; however, loss of all sources would result in the automatic start-up of the diesel generators to supply power. Low Level Waste (LLW) is waste containing a low level of radioactivity as defined by NRC regulations. LLW is usually in the form of scrap paper, plastic, tape, tubing, filters, scrap parts, dewatered resins, etc. LLW requires packaging to prevent the spread of contamination but little radiation shielding. Maintenance Rule is the NRC proposed rule which requires that nuclear power plant licensees monitor the performance or condition, or provide effective preventative maintenance of certain structures, systems and components against licensee established goals. The Rule becomes effective July 10, 1996. Microbiologically-Influenced (or Induced) Corrosion (MIC) is cor-rosion, usually in the form of pitting, on steel piping systems containing stagnant or low-flow water conditions. The corrosion is caused by surface-attached microbe-produced chemicals which attack the piping surface. Depending on J-3
and chemical cleaning severity, MIC is controlled by mechanical combined with biocides. or closed by remotely Motor-Operated Valves are valves opened motors. The valves are or locally-operated integral electric block or control used in power plant piping systems to divert, the flow of steam or water. Nuclear Excellence Team (NET) is a organization of several is "To improve plant well-qualified senior people whose mission self through the use of performance-based performance Generation) within the NPG (Nuclear Power assessments organization."

Reactor Coolant System (RCS) is the collection of piping, pumps, pressurizer, and reactor vessel, steam generators, the associated valves which function to circulate water through reactor to remove heat. J-4
Refueling Outage is a normal shutdown of a nuclear power unit to permit refueling of the reactor, along with maintenance, inspections and modifications. Typical DCPP refueling outages occur about every 18 months and last for about two months. The outages are numbered by unit number (I or 2), "R", and the consecutive outage number. For example, "IR5" is the fifth refueling outage for Unit 1 since start-up. Reliability Centered Maintenance (RCM) is the practice of maintaining equipment on the basis of the logical application of reliability data and expert knowledge of the equipment, i.e., a systems approach. Normal preventive maintenance (PM) is performed on the basis of time, i.e., maintenance operations are performed on a schedule to prevent poor performance or failure. Residual Heat Removal (RHR) is the removal of the residual heat generated in the reactor fuel after reactor shutdown to prevent the fuel overheating and possibly melting. The heat removal is performed by a set of pumps, piping, valves and heat exchange equipment circulating water by the fuel while the reactor is shut down. Safety System Functional Audit and Review (SSFAR) is an investigation of a single plant safety system from all perspectives such as design basis, operations, maintenance, engineering, testing, materials, problems and resolutions, quality control, etc. The review is performed by a multi functional team and can last several months. Simulator is a simulated nuclear power reactor control room with gauges, instruments and controls connected to a computer. The computer is programmed to behave like a nuclear reactor and respond to operator actions and commands. The simulator is used in training nuclear operators in controlling the reactor and responding to simulated transients and accidents. Spent Fuel Pool (SFP) is an in-plant stainless-steel-lined concrete pool of water into which highly radioactive spent nuclear fuel is stored when it has been discharged from the reactor. The spent fuel is maintained in the pool until its ultimate disposal is determined. Steam Dump Valve is a device to discharge (dump) steam from the power plant piping to lower its pressure and reduce the energy in the line. This is done to permit faster shutdowns. Steam Generator is a large, vertical, inverted-U-tube-and-shell heat exchanger with hot reactor coolant on its tube side J-5
