20001 South Texas Project Electric Generating Station Units 1 and 2 Docket Nos. STN 50-498; STN 50-499 South Texas Proiect Operational Readiness Plan Clarification
Reference:
Correspondence from William T. Cottle (HL&P) to James M. Taylor (NRC), dated August 28, 1993 (ST-HL-AE-4556)
Dear Mr. Taylor:
On August 28, 1993 Houston Lighting & Power (HL&P) submitted the Operational Readiness Plan (ORP) for the South Texas Project.
Since then there has been significant progress on achieving the goals setforth in that plan.
Implementation of the ORP, as with most
- plans, has identified ref$nements and items requiring clarification.
These
- changes, summarized
- below, will be incorporated into Revision 1 of the Operational Readiness Plan.
This revision will be developed to support the return of Unit 2 to power operation.
In order to incorporate lessons learned from Unit 1, it will be submitted 45 days af ter Unit 1 attains the 100%
powar assessment plateau.
Technical Trainino Excerpt from Operational Readiness Plan, Revision 0, Page 24 e
Two additional personnel weaknesses identified during the evaluation of technical training were a less than adequate understanding of plant systems and an insufficient number of certified journeyman to accot.plish routine tasks.
To address both needs, an aggressive training schedule to be completed by the end of December 1993 has been implemented.

Houston Lighting & Power Company South Texas Project Electric Generating Stati ST-HL-AE-100004 File No.: G36 Page 2 of 6 Clarification STP's 1993 goal associated with certification has been achieved.
This required 658 (173 electrical, 260 mechanical, 225 Instrumentation and Control) certifications to be achieved.
- Also, 81 incumbent journeyman needing system training have completed that instruction.
This ORP action is complete.
Supervisorv Traininc Excerpt from Operational Readiness Plan, Revision 0,
. age 24 To address weaknesses in performance of Maintenance Supervisors, a supervisor training program has been developed to ensure full compliance with ACAD 90-10,
" Guidelines for Maintenance Supervisor Selection and Development. "
Training using this program has been completed for Mechanical Supervisors and is scheduled to be complete for Electrical and I&C Supervisors by the end of 1993.
Clarification Training has been accomplished for those Mechanical, Electrical and Instrumentation and Control Supervisors (directly supervising craft activities),
incumbent to their positions prior to the reorganization of the maintenance department to support unitization.
Training of new supervisors is scheduled for completion during 1994.
Only supervisors that directly supervise craft activities are included in this training.
Performance Measures Used to Monitor Maintenance Effectiveness e
Excerpt from Operational Readiness Plan, Revision 0, Page 25 Indicators to be used to monitor station material condition are (only two of seven listed):
- Main Control Board deficiencies.
(Goal:
less than 10)
PM deferral rate.
(Goal: less than 20)
- R\\93-365.001

Clarification
- Main Control Board Deficiencies The goal set for this category is currently less than 10 prior to power operation.
However, it should be recognized that some MCB deficiencies will-be " work complete" but not in-service because post-maintenance / operability tests require at power conditions.
Also, because of the length of time the unit has been shutdown with instruments out of service, it is anticipated that as mode changes occur the number of deficiencies will temporarily rise above 10.
Therefore, the goal is being restated as follows:
No outstanding deficiencies that adversely effect Operations i
ability to effectively monitor plant conditions at each mode; with a goal of < 10 at the 100% power assessment plateau.
Preventive Maintenance Deferral Rate Although the goal of less chan 20 PM deferrals has been
- achieved, further evaluation has indicated that a fixed number is not an effective nor practical indicator for long term success.
The new goal, consistent with the STP Business Plan, is to achieve and maintain a PM Deferral Rate of < 5%.
Eauinment Labelino e
Excerpt from Operational Readiness Plan, Revision 0, Page 35 1
A comprehensive relabeling program incorporating the guidelines of INPO Good Practice OP-28, " System and Component Labeling" and EPRI NP-6209, " Effective Plant Labeling and Coding" is being implemented.
Program requirements will be in-place and a pilot program involving the Standby Diesel Generators will be completed by the end of 1993.
e ClarificatiQD The pilot program involving the Standby Diesel Generator is limited to mechanical components and instrumentation for the engine. The electrical portion of the Standby Diesel Generator relabeling effort will be in conjunction with the plant electrical distribution systems.
Support systems, such as the air start system, also are not included in the initial program.

A Business Plan strategy has been developed to address plant reliability improvements. The strategy will assess the existing Preventive Maintenance and Reliability Centere'd Maintenance (RCM) programs to foster the development of.a comprehensive reliability-based, predictive / preventive maintenance program with a documented basis. The strategy will also provide for the review of all existing PMs to ensure they are applicable and effective, and an evaluation of the PM program process, including
- software, to identify elements that require enhancement.
This effort will be accomplished through an integrated approach composed of the performance of detailed EPRI style RCM on approximately 10 systems,- streamlined RCM on approximately 40 systems, and a comprehensive review of PM tasks to develop a complete PM basis, o
Clarification The description of the Reliability Centered Maintenance (RCM) program provided in the ORP was based upon the draft plan submitted for the STP Business Plan.
At the time the ORP was submitted, the business planning process was ongoing.
As a result of discussions during this process and input from other utilities that utili' zed the in-depth RCM process, it was determined that more benefit would be gained by STP by changing the performance of detailed the original proposal from:
EPRI style RCM on approximately 10 systems, streamlined RCM on approximately 40 systems, and a comprehensive review of PM tasks to develop a complete PM basis. " to the perforuance of detailed EPRI style RCM on three systems, streamlined RCM on the 47 remaining systems, and a comprehensive review of PM tasks to 1
develop a complete PM basis."
i Assessment Proces_q The assessment schedule, as described on page 14 of the ORP, calls for an assessment milestone af ter one week of full power operation.
3 After further consideration, it was decided that an assessment i
af ter 10 days of full power operation would provide more meaningful information.
Therefore, as a minimum, formal assessments will be conducted prior to Mode 4, prior to criticality, prior to power j
j ascension above 50% power, and after 10 days of full power i
operation.

ATTACHMENT 1 Status Summary of Regional Staff Actions Staff Action 1.(a):
Assess operating staff workload issues at STP and the management actions to resolve them.
Status:
This restart issue has been resolved.
The licensee's Operational Readiness Plan addressed several initiatives to increase staffing and to reduce the administrative workload of the operators. The Region IV inspection in this area was performed in two segments. The first segment was conducted the week of November 1, 1993, and the second segment was conducted the week of November 29, 1993. NRC Inspection Reports 50-498/93-40; 50-499/93-40 and 50-498/93-41; 50-499/93-41 were issued on December 1 and December 16, 1993, respectively. The first inspection found that the licensee had made substantial progress toward resolving the restart issue.
The second inspection focused on implementation effectiveness.
This inspection found that the licensee's corrective actions have been effective in correcting the problems of marginal operator staffing. These actions included relieving the operating crew of administrative burdens by transferring duties to the newly formed operations work control group; adding a sixth crew of operators which will begin watch rotation in January 1994; training 20 additional non-licensed operators and placing additional non-licensed operators on each crew; transferring certain duties from the operations department to the technical services department, and providing engineering support to operations and maintenance around the clock. Open followup items involve NRC evaluation of the implementation of the 6-shift watch rotation in January 1994.
Staff Action 3:
Conduct a followup inspection of the fire protection deficiencies at STP.
Status:
The following two restart issues have been resolved:
1)
Adequacy of fire brigade leader training and qualifications, and 2) Adequacy of the fire protection computers and software, the licensee's success in reducing the number of spurious fire protection system alarms, and other fire protection hardware problems.
The first segment of the Region IV inspection of these issues was conducted during the week of October 18, 1993.
Results of this inspection (Inspection Report 50-498/93-37; 50-499/93-37 issued on November 23,1993) were favorable, indicating considerable progress. A followup inspection was
' conducted the week of December 13, 1993. Results of the inspections are summarized below.
i 1.
Fire Brigade Team Leader Training The concerns of the fire brigade leaders' knowledge of facility safe shutdown systems, and the impact on the operations staff has been reviewed by Region IV staff.
The region concluded that the current fire brigade leader training program meets the regulatory requirements of Appendix R to 10 CFR 50 regarding the STP fire brigade leaders' knowledge of safe shutdown 4
systems. The licensee's effort to validate the current program learning objectives by a comparison review against the licensed operator training program was effective. Upon completion of the design and implementation of a new training program that is being developed, the licensee's training program will far exceed industry standards. The licensee's current effort to provide extra personnel, by training six i
additional personnel qualified to perform as fire brigade leader, will remove all burden from plant operations personnel, to staff the position of fire brigade leader.
2.
Fire Protection Computer Alarm System Regional personnel determined that the licensee's efforts to significantly reduce the distraction of control room operators by the fire protection computer alarm system had been successful. The number of spurious alarms noted during the DET was characterized as 20-30 per day. During the followup inspection, inspectors observed 4-5 alarms per day. All alarms were being trended to identify additional problems i
with additional computer alarm points. There was indication that information retrieval had been improved due to the improved computer alarm descriptions.
There was an apparent increase in operator sensitivity to the information provided by the fire detection system and control room operators appeared to De less distracted. The conclusion was reached that the performance of the fire detection and computer system had been significantly enhanced by the numerous hardware and software changes. Startup of i
Unit I should not be delayed because of this issue.
The licensee will need to address the Unit 2 fire protection computer alarm system separately.
)
c.
3.
Fire Protection Systems Service Request Backlog 1
Region IV inspectors concluded that the licensee had identified all the work necessary tc address the material condition of the fire detection and suppression systems. A determination of work progress and quality was made during the followup inspection to assess the improved condition of the fire protection systems. This inspectior, found that STP management had performeo effectively in addressing the degraded material condition of the Unit I and common fire protection systems.
The licensee's process had identified a significant number of new hardware 4
deficiencies, which were being worked to completion.
A significant portion of the work (80-85 percent) had been completed and the remaining items were being completed at a higher rate than originally expected.
The region concluded that the status of the Unit <1 and s
common fire protection systems maintenance and repair backlog should not be an issue affecting the scheduled d
startup of Unit 1.
t 4.
Control of Transient Combustibles The inspection results showed that the licensee had I
increased empnasis on control cf transient combustible i
material. This effort in conjunction with the licensee's existing administrative procedures was providing a more effective program.
During plant tours, the inspectors found that the plant was generally clean and that outage work areas were well policed. The transient combustibles observed were within the combustible loading for the areas.
Continued effectiveness of the transient combustible i
control program will require close control and involvement by licensee management with specific j
emphasis on generating a sense of individual responsibility by all employees.
The control of transient comoustibles should not impact the scheduled startup of either unit.
5.
Degraded Fire Barrier Penetration Seals The inspection results indicated that the licensee had taken appropriate and timely corrective action for the i
shrinking and cracking of the hydrosil fire barrier penetration seals.
The bulk of this action involved creating, testing, and implementing a valid repair process. Since the per.etration seal desiccation process was time dependent, the failures extended over
, a long period and show a rapid decrease in failure l
rate, from 27 percent in 1990 to 6.1 percent in 1991 and 3.9 percent in 1993. Regional inspectors agree with the licensee's opinion that the most significant seal degradation has already taken place.
Further degradation should be very limited, and will be repaired on a case by case basis, when identified within the normal surveillance program. There was no evidence that the evaluation, investigation, and repair processes were unduly delayed.
It appears that management was well aware of the problem and supported the recovery efforts.
Staff Action 8:
Review and evaluate the licensee's response to the j
diagnostic evaluation report for completeness.
Prepare an appropriate reply for ED0 signature.
i Status:
This item was completed with the issuance of the EDO letter to the licensee on November 18, 1993.

COMPLETION OF SOUTH TEXAS PROJECT UNIT 1 CONFIRMATORY ACTION LETTER ITEMS AND RESTART ACTION PLAN STATUS The purpose of this memorandum is to document the discussions and presentation to you on February 15, 1994, which informed you of the status of Houston Lighting & Power Company's (HL&P) actions to implement the South Texas Project (STP) Confirmatory Action Letter (CAL 4-93-048) dated October 15, 1993, and the status of tasks associated with the STP Restart Action Plan for Unit 1.
Confirmatory Action Letter On February 3,1993, following a reactor trip, the Unit 2 turbine-driven auxiliary feedwater pump started and immediately tripped on overspeed. On February 4,1993, Unit I was required to shut down as a result of repeated i
failures of the turbine-driven auxiliary feedwater pump to start on demand and operate without tripping on overspeed. As a result of these problems, NRC issued a Confirmatory Action Letter (CAL) to HL&P on February 5, 1993, and dispatched an augmented inspection team (AIT). The CAL required resolution of the overspeed trip condition affecting the turbine-driven auxiliary feedwater pumps and a briefing of NRC staff prior to restart of the unit.
In addition to the AIT activities, several special inspections were conducted at STP, including a diagnostic evaluation by the NRC office of Analysis and Evaluation of Operational Data conducted during the period of March 29 to April 30, 1993. The findings of these reviews resulted in supplements to the CAL issued on May 7, 1993 (CAL 4-93-04), and October 15, 1993 (CAL 4-93-04B).
These supplements included issues that NRC considered of sufficient scope and safety significance to require resolution prior to either unit being restarted (Enclosures 1, 2, and 3).
Licensee Actions In addition to the hardware related issues at STP, the NRC required HL&P to address programmatic problems, including work backlogs, postmaintenance testing shortcomings, outstanding modifications, operations staffing adequacy, fire protection equipment and training, management effectiveness in identifying, pursuing, and correcting plant problems, and the results of internal restart readiness reviews.

SUBJECT:
COMPLETION OF SOUTH TEXAS PROJECT UNIT 1 CONFIRMATORY ACTION LETTER ITEMS AND RESTART ACTION PLAN STATUS The purpose of this memorandum is to document the discussions and presentation to you on February 15, 1994, which informed you of the status of Houston Lighting & Power Company's (HL&P) actions to implement the South Texas Project (STP) Confirmatory Action Letter (CAL 4-93-048) dated October 15, 1993, and the status of tasks associated with the STP Restart Action Plan for Unit 1.
Confirmator_y Action Letter On February 3,1993, following a reactor trip, the Unit 2 turbine-driven auxiliary feedwater pump started and immediately tripped on overspeed. On February 4, 1993, Unit I was required to shut down as a result of repeated failures of the turbine-driven auxiliary feedwater pump to start on demand and operate without tripping on overspeed. As a result of these problems, NRC issued a Confirmatory Action Letter (CAL) to HL&P on February 5, 1993, and i
dispatched an augmented inspection team (AIT). The CAL required resolution of the overspeed trip condition affecting the turbine-driven auxiliary feedwater pumps and a briefing of NRC staff prior to restart of the unit.
In addition to the AIT activities, several special inspections were conducted at STP, including a diagnostic evaluation by the NRC office of Analysis and Evaluation of Operational Data conducted during the period of March 29 to April 30, 1993. The findings of these reviews resulted in supplements to the CAL issued on May 7, 1993 (CAL 4-93-04), and October 15, 1993 (CAL 4-93-04B).
These supplements included issues that NRC considered of sufficient scope and safety significance to require resolution prior to either unit being restarted (Enclosures 1, 2, and 3).
Licensee Actions In addition to the hardware related issues at STP, the NRC required HL&P to address programmatic problems, including work backlogs, postmaintenance testing shortcomings, outstanding modifications, operations staffing adequacy, fire protection equipment and training, management effectiveness in identifying, pursuing, and correcting plant problems, and the results of internal restart readiness reviews.
In response, the licensee developed ther J

uperational Readiness Plan submitted to the NRC in August 1993, which described specific actions to be taken prior to the resumption of power operation. Additionally, longer-term actions were described in the Business i
Plan submitted to NRC -in October 1993. HL&P has initiated changes in the STP i
management from the Group Vice President, Nuclear to the Plant Managers, including a reorganization of the Nuclear Generation department.
a On January 29, 1994, HL&P requested a meeting to brief the NRC on the status j
of the issues described in the February 5, 1993, CAL and its supplements.
In the licensee's written submittal they described the actions taken in response to NRC concerns and included a summary of actions remaining prior to j
l resumption of power operation. A public meeting was conducted at the site on February 14, 1994, and a briefing of the STP Restart Panel was conducted by teleconference on February 15, 1994, during which the licensee confirmed actions taken in preparation for the resumption of power operation of STP, Unit 1.

NRC Actions l
The NRC Region.IV Regional Administrator chartered the STP Review Panel on March 11, 1993.
The STP Review Panel is composed of regional and program office managers and is to:
(1) assure that a consistent approach to issues is i
being identified at STP and attempt to reach an agency consensus and united j
approach to addressing the problems at STP; (2) assure that the followup on safety significant issues is being properly coordinated and scheduled; 4
(3) schedule significant meetings and inspections; (4) assure that the views and concerns of different NRC offices are properly addressed; and (5) assure proper coordination for the followup of issues that are identified by the Diagnostic Evaluation Team (DET) inspection.
On April 12, 1993, it was determined that NRC Inspection Manual Chapter 0350,
" Staff Guidelines for Restart Approval," was applicable for STP because of its extended shutdown and previous indications of serious deficiencies in licensee management effectiveness. The STP Review Panel assumed the role and responsibilities of the STP Restart Panel and issued the STP Restart Action Plan (Enclosure 4) which includes expected NRC actions required to be taken before restart of the STP Units.
In addition to the focused inspections conducted at STP since the shutdown of Units 1 and 2, an independent Operational Readiness Assessment Team (ORAT) inspection, led by the Special Inspection Branch of the Office of Nuclear Reactor Regulation, was conducted from December 6-10, 1993, and January 12-21, 1994. At the exit meeting conducted on January 21, 1994, the licensee committed to the resolution of issues regarding:
(1) configuration management; (2) motor-operated valve opening under system pressure; and (3) surveillance weaknesses. The ORAT concluded that, pending the results of licensee actions concerning the above three items, the ORAT team would be generally supportive of a' restart of Unit 1.

CONFIRMATORY ACTION LETTER SUPPLEMENT 2 This is the second supplement to my Confirmatory Action Letter of February 5, 1993, which noted Houston Lighting & Power Company's management agreement that South Texas Project, Units 1 and 2, will not be taken critical until the NRC staff has been briefed on the results of your efforts to correct the overspeed trip condition which affected the turbine-driven auxiliary feedwater pumps.
As discussed with Mr. John Groth in a public meeting in Arlington, Texas, on October 5, 1993, the following topics have been identified as additions to the issues which must be resolved prior to startuo of either South Texas Project unit.
In a telephone conversation on October 15, 1993, you acknowledged these issues and agreed that these topics would be addressed in your briefing of the NRC staff in a meeting to be scneduled prior to unit startup.
The additional topics are:
Effectiveness of the SPEAXOUT program; Standby diesel generator reliability; Essential chiller reliability; The system certification program; Reliability and operability of the feedwater isolation bypass valves; Adequacy of tornado dar.ioer testing; and Acceptability of the emergency prepareoness accountability drill results.
These are not new issues, but they were considered to be significent following reviews of the Diagnostic Evaluation Report, your Operational Readiness Program, the allegation process, and recent NRC inspection findings. The complete results of these reviews are documented in NRC Inspection Report 50-498/93-31; 50-499/93-31.
This listing of topics for discussion is CERTIFIED MAIL - RETURN RECEIPT RE0 VESTED Q\\ OCD G
Houston Lighting & Power Co. intended to focus the briefing on staff concerns involving potential safety issues.
If other such topics are identified prior to the briefing, you will be advised by letter or telephone.
Please inform me when your staff has made significant progress in addressing these issues so I can schedule special inspections prior to the briefing.
All provisions of the February 5, 1993, letter and its supplement of May 7,1993, remain in effect.
If you have any questions, please feel free to contact me or Mr. Art Howell of my staff.
