ENCLOSURE 1
Restart Readiness Assessment Nine Mile Point Unit 1
~Back round Nine Mile Point Unit 1
was placed on the NRC's list of plants warranting close monitoring in June 1988.
The unit had been shut down since December 1987 when a
manual scram was initiated due to a
The unit initially remained shut down due to extensive problems identified by NRC in the inservice inspection program.
As a result of a March 1988 inspection, Confirm-atory Action Letter (CAL) 88-13 was issued to formalize Niagara Mohawk commit-ments to correct documentation deficiencies in their licensed operator requal-ification program.
To address a broader spectrum of performance deficiencies which were identified prior and subsequent to the December 1987
- shutdown, CAL 88-17 was issued in July
- 1988, superseding CAL 88-13, and documenting Niagara Mohawk's commitment not to restart the unit until corrective actions for these broader issues wer'e completed and restart was authorized by the Regional Administrator.
Niagara Mohawk formed a special task force to prepare a comprehensive restart plan.
Following an exhaustive root cause determination and subsequent Niagara Mohawk staff review and approval, Niagara Mohawk submitted their Unit 1 Restart Action Plan (RAP) to the NRC staff in December 1988.
The RAP identified five underlying root causes (URCs) for past performance deficiencies and 18 specific issues representing the major technical and administrative problems.
The URCs were:
( 1) Planning/Goal Setting; (2) Problem Solving; (3) Organizational Cul-ture; (4) Standards of Performance/Self-Assessment; and (5) Teamwork.
An NRR Special Team Inspection (STI) was conducted from January 30 through March 3, 1989 to independently determine the root causes for Niagara Mohawk's performance deficiencies.
The STI identified no new root
- causes, but addi-tional examples of previously identified problems were noted by the team.
Fol-lowing two revisions of the RAP, based upon staff comments and review of public comments from an August 23, 1989 meeting in
- Oswego, New York, the NRC staff gave final approval of the plan on September 29, 1989.
Niagara Mohawk completed an assessment of the effectiveness of its corrective actions and documented it in a letter dated September 8,
1989.
After a special NRC team review of this Restart Readiness Report found the Niagara Mohawk read-iness self-assessment process to be
- adequate, the NRC staff conducted an Inte-grated Assessment Team Inspection (IATI) in October 1989.
The IATI evaluated Niagara Mohawk's progress in resolving the five underlying root causes for the performance deficiencies which were documented in the Restart Action Plan (RAP).
The team
- found, in general, that the RAP was in place, but was being implemented with varying.degrees of success in the areas associated with the five URCs.
The team concluded that clear improvement was demonstrated in the
~ areas of planning/goal
- setting, organizational culture and teamwork;
- however, additional work was needed in the areas of problem solving and standards of performance/self-assessment.
Attachment The most recent SALP assessment period for Nine Mile Point Units 1 and 2 ended in February 1990.
The results of the assessment concluded that while positive efforts were being made in three of the areas assessed as Category 3 in the prior assessment period (operations, maintenance/surveillance, and safety assessment/quality verification),
overall performance improvements in these functional areas were not sufficient to war rant changes from the previous ratings.
In May 1990, a
Readiness Assessment Team Inspection reviewed Niagara Mohawk's overall progress in preparing Nine Mile Point Unit 1 for restart.
The team concluded that adequate progress was demonstrated in resolving the underlying root cause areas of problem solving and standards of performance/self assess-ment, that improved performance was sustained in the other three URC areas and that there were, no observed impediments to Unit 1 restart.
In addition, the RATI noted continuing performance improvements in the three SALP functional areas rated Category 3 in the last assessment period.
In a letter dated'uly 13,
- 1990, Niagara Mohawk indicated that with the except-ion of routine prestartup surveillance
- testing, corrective maintenance, and administrative reviews which remain to be completed, Nine Mile Point Unit 1 is ready for restart.
The following assessment utilizes the evaluation criteria provided in Section 0350-04.03 of NRC Inspection Manual Chapter
- 0350, Staff Guidelines for Restart Approval.
Root Cause Identification and Correction As stated
- above, the NRC staff reviewed and approved the Unit 1 Restart Action Plan (RAP) on September 29, 1989.
The RAP took approximately six months to develop by Niagara Mohawk and involved the participation by both employees and management, including the Chief Executive Officer and Board of Directors.
A comprehensive reexamination of previously performed
- audits, assessments and inspections of Niagara Mohawk by the
- NRC, independent third parties and various internal groups was performed in conjunction with an exhaustive search for. any current or potential concerns.
This information was used as a basis for deriv-ing the underlying root causes of their past performance deficiencies.
- Next, corrective actions were developed to address these underlying root causes and an extensive independent verification process was used to assess the effective-ness of these corrective actions.
- Lastly, and in accordance with CAL 88-17, Niagara Mohawk conducted a comprehensive self-assessment to assure themselves that the corrective actions completed and/or ongoing were effective in resolv-ing the underlying root causes.
Attachment The staff concluded, based upon careful scrutiny by the NRC Restart Assessment
- Panel, special assessment team inspections and specialist inspections, that the RAP was comprehensive and adequately addressed both the hardware specific and broader organization/management problems which had to be sufficiently resolved prior to restart of Unit 1.
Subsequent to the NRC staff approval of the
- RAP, numerous specialist inspections have concluded that the technical resolution of identified hardware and program deficiencies were satisfactory.
Additionally, the Integrated Assessment Team Inspection
( IATI) and subsequent Readiness Assessment Team Inspection (RATI) have found clear improvement in correcting the underlying root causes related to management and organizational problems.
The RATI noted particular improvement in the problem solving and standards of performance/self-assessment areas over that identified during the IATI.
Although not specifically reviewed by the
'NRC staff, Niagara mohawk has developed a long-range
- plan, the Nuclear Improvement Plan (NIP), to'ontinue improving the Nuclear Division's performance.
The corrective actions in the NIP extend beyond Unit 1 restart to address many of the management actions necessary for sustained Nuclear Division improvement.
Mana ement Or anization and Oversi ht Niagara Mohawk management has demonstrated their commitment to improvement and has exhibited the necessary leadership and dedication of resources to bring it about.
The selection of a
new Executive Vice President in the fall of 1988, and earlier a
new General Superintendent, indicated a'esire to change and enhance the Nuclear Division's leadership and break tradition from promoting strictly from within the company.
Since that time and with the implementation of the Restart Action
- Plan, there have been increased senior management presence and involvement on site.
Additionally, the staffing of a site engi-neering organization and the system engineers of both units represent a signif-icant commitment of resources and a clear effort to enhance the engineering staff support and communications with the station operating staff.
As stated in the recent SALP, there was an apparent turning point in Niagara Nohawk's overall performance and approach to assuring quality.
This new approach appeared to have enabled improved results in the engineering and sur-veillance areas and the generally improving direction in most other areas.
The quality assurance department has been effective in identifying problems, and both the onsite and offsite safety review committees have demonstrated improved assessment and oversight capabilities.
The establishment of the Independent Assessment Group reporting to the Executive Vice President was viewed as a
good initiative to enhance self-assessment.
Progress towards com-pletion of the Unit 1 refueling outage has not been hurried or schedule-driven.
Emphasis has been placed upon completing the individual tasks carefully, corn" petently and safely.
r
Attachment The RATI noted good teamwork and evidence of sound engineering and technical support for ongoing station activities.
Problem identification and resolution methodology and controls were found to be satisfactory, and evidence of improv-ing self-assessment capability was noted.
Effective implementation of correc-tive actions required by the RAP and the successful operation of Nine Mile Point Unit 2 have provided evidence of Niagara Mohawk's ability to accomplish established goals and objectives.
Recent senior management changes represent a potential challenge to the con-tinued progress in institutionalizing the corrective actions implemented to date.
- However, transition periods have been established and the current Executive Vice President will maintain a position on the Board of Directors and
'he Board's Nuclear Oversight Committee to ensure continuity in leadership.
Plant and Cor orate Staff Readiness In March
- 1988, NRC identified documentation deficiencies associated with the Unit 1 requalification program.
Subsequently, weaknesses were also identified in the operators'epth of knowledge and familiarity with Emergency Operating Procedures.
In July 1989, an NRC Requalification Program evaluation at Unit 2
resulted in that program being found unsatisfactory.
Significant improvement in performance by the licensed operator staff of both units has been demon-strated as a result of Niagara Mohawk's corrective actions.
The most recent Unit 2 Requalification program evaluation in May 1990 found all examined oper-ators (6
SROs and 9
ROs) passed all portions of the examination with continued improvement in detailed program areas.
The continued improvement at Unit 2
serves as a positive measure of corporate staff readiness to operate Unit 1
because of Niagara Mohawk's use of a common training department under corporate controls common to both units.
An evaluation of the Unit 1 Requalification Program in July 1990 also found that all examined operators (9
SROs and 6
ROs) passed all portions of the examination.
- Further, inspections have shown clear improvement in operator performance and understanding of Emergency Operating Procedures.
There has been a
marked improvement in cooperation and teamwork within the operations staff and between the operations and training staffs over that which existed prior to the extended outage.
The most recent SALP report rated the Unit 1 Operations functional area as Category 3.
The operator training concerns from the previous SALP period were adequately addressed.
- However, the day-to-day performance of licensed opera-tors had varied from good control of hydrostatic testing and refueling activi-ties to a
number of events caused by personnel errors.
More effective manage-ment, particularly of daily operations, appeared to be needed to raise overall operations department performance.
Attachment Operations and maintenance staff performance has improved since the end of the SALP period as indicated by a reduction in events caused by personnel errors.
Many of the initiatives developed towards the end of the SALP period have begun to have a positive effect on daily operations.
Procedures have been substan-tially upgraded, and there is evidence of a
strong commitment to procedural adherence.
Work-in-Progress Forms and Troubleshooting Plans have been effec-tively implemented and have improved overall control and planning of work and troubleshooting activities.
The recently staffed system engineers appear to be knowledgeable and experienced.
Observations have indicated that the system engineers are being effectively used to resolve system problems and to coordinate the various disciplines on site and in the corporate engineering office.
Evidence of more management oversight of daily activities has been observed.
The RATI found clear evidence of improved teamwork 'and a significant improvement in attitude toward safety.
The corporate staff appears capable of supporting safe plant operation.
Recent problems with the reactor building closed loop cooling heat exchangers were properly addressed by both station and corporate engineering.
Coordination and management oversight of the various departments and contractors involved in the repair and testing processes were satisfactory.
The current level of performance is adequate to support safe operation of the unit.
Generally, performance has been good and is getting better.
For
- example, the integrated system test under loss of offsite power conditions was recently completed in a commendable manner.
On those infrequent occasions when performance has not been acceptable, corrective actions have generally been appropriate and Niagara Mohawk has addressed NRC concerns.
In particular, on May 23 the No.
11 feedwater pump was run for a
few seconds with the suction valve closed.
Operator errors were addressed and inappropriate uses of the tagging system during testing were corrected plant-wide.
Niagara Mohawk is responding to additional NRC concerns that weaknesses within this tagging sys-tem could hamper effective configuration control and that the root cause analysis of the feedwater event was incomplete because it did not effectively deal with the configuration control aspects of the event.
The licensee's schedule and the progress to date in addressing these issues is consistent with the planned restart date.
'The Panel will confirm the
. adequacy of the licen-see's short and long term corrective actions as they are implemented.
Ph sical State of Readiness of the Plant Niagara Mohawk's Restart Action Plan (RAP) included both corrective actions for the underlying root causes of past performance deficiencies and corrective actions for 18 specific issues.
The majority of the specific issues involved technical and hardware concerns which either contributed to the NRC staff's issuance of the CAL or were the result of closer examination of unit operations by the NRC and Niagara Mohawk after the CAL was issued.
Each of the specific issues listed in the RAP has been adequately addressed by Niagara Mohawk and reviewed by the NRC staff.
Although not reflected in the
- RAP, a
number of additional emergent technical issues have been identifi'ed and appropriately resolved by Niagara Mohawk since the issuance of the final'evision to the RAP.
r
Attachment
- Again, the NRC staff has closely monitored and reviewed each of these new technical issues and found their resolution satisfactory for unit restart.
Examples of recent technical issues are the feedwater/HPCI system performance verification problems, motor generator set voltage regulation problems and the resolution of the design and tube damage concerns for the reactor building closed loop cooling heat exchangers.
With only a
few remaining work items and post-maintenance tests to complete, the Niagara Mohawk staff has successfully completed over 20,000 individual work items to prepare for unit restart.
The NRC staff has reviewed a
sample of these items throughout the outage and closely monitored the major critical path activities and evolutions towards the end of the outage.
In
- general, the quality of work and overall performance of the Niagara Mohawk organization in completing the remaining open items have been satisfactory.
Prior to startup all outage related work requests will be completed and the non-outage work requests remaining open is expected to be below 500 total for Unit 1.
The RATI concluded that the current maintenance and surveillance activity controls and the licensee's staff performance standards provide ade-quate assurance that safety systems will be maintained and properly tested to support unit restart.
The NRC staff has reviewed and found acceptable the Niagara Mohawk plans for unit startup and power ascension testing.
In addition, the staff reviewed a
large sample of the power ascension and surveillance test procedures and con-cluded that they are technically adequate, address outstanding testing issues and are acceptable for restart.
The staff concludes that the plant is physically ready for restart pending completion of a
few minor identified work items.
Re viator Re uirements -
NRC Activities The NRC has significantly increased the inspection activities at Nine Mile Point since Unit 1
shutdown in December 1987.
Extensive coverage has been expended by resident, region-based and headquarters inspectors especially in the areas detailed by CAL 88-17 and the Restart Action Plan.
Numerous team inspections have been part of this expanded inspection coverage.
The Readiness Assessment Team Inspection in May 1990 evaluated Niagara Mohawk's progress in resolving the five underlying root causes, particularly the areas of problem identification/resolution and standards of performance/self-assess-ment.
The team concluded significant progress had been made and that no impediments to restart existed.
r Attachment Niagara Mohawk has satisfactorily resolved and received NRR staff review and approval of all outstanding licensing issues necessary for restart.
Licensed operator requalification program concerns have been adequately
- resolved, and there are no outstanding concerns.
In preparation for the restart, the NRC has developed an augmented inspection plan.
The inspection coverage will provide for the assessment of routine and special evolutions performed by Niagara Mohawk during the unit startup and power ascension test program.
Conclusion The staff has concluded that Niagara Mohawk is ready to restart and safely operate Nine Mile Point Unit 1.
Due to the extended length of the
- shutdown, the scope and depth of past performance deficiencies which existed, and recent senior management changes which could challenge the continued progress of implemented corrective
- actions, the staff recommends a two-part release from CAL 88-17.
The initial release would be established by a
supplement to CAL 88-17 which permits the startup of Nine Mile Point Unit 1.
The CAL supplement would also confirm Niagara Mohawk's commitment to perform self-assessments at specified power ascension testing plateaus and to brief the NRC Restart Assessment Panel on the results of these self-assessments prior to proceeding to the next testing plateau and prior to routine full power operations.
The final release from CAL 88-17 will be based on Niagara Mohawk's overall report on the power ascension test program and self-assessments and on an NRC/Niagara Mohawk management meeting on these topics.
