1 I. HIGHLIGHTS' 4

The month of February, 1987 was significant in the course of implementing the Rancho Seco Action Plan. During this time, the majority of the programs detailed in the Action Plan were active and several major milestones were reached:

e On February 28, 1987, the Action Plan was updated with the issue of Amendment.3. This amendment detailed and refined the

. closure progress on each Manager's Restart work. Each System l Engineer enumerated the modifications, testing, training, and t new procedures which were necessary to prepare his system for restart.

e The new TOI diesels were' installed and passed their 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> run tests: The "35 consecutive starts" test is now progressing. This project is ahead of schedule.

!

• Testing began on the Emergency feedwater Initiation and Control system (EFIC). A portable simulator was connected to conduct testing of the various panels and cabinets.

• A significant number of NRC "Open Items" (specific action items 3 identified during NRC inspections) were closed in February.

Only 140 of the 402 open items remained open on February 28.

a Efforts continued to resolve the entire cable issue. As a 1 conservative measure, 243 cables are being " walked down" to determine whether they are physically located as designed.

Only 11 relatively minor discrepancies have been found, leading to optimism that this issue will not be critical to scheduled restart.

• A very significant milestone was approached as the Reactor Coolant system was readied for refill. This event culminated a

, sequence of prerequisite which in their aggregate indicate i

major progress in mechanical and electrical readiness to

restart.

• The American Nuclear Insurers (ANI) inspection occurred in February. Their exit briefing was positive, but did include some concerns.

• In February, the 14-man team from Nuclear Reactor Regulation (NRR) and NRC Region V finished their 4-week on-site inspection '

of 7 key systems. Their exit comments were mixed. The l i District awaits the final Inspector Report from NRR, due March i 4

30, 1987. I t  :

I. HIGHLIGHTS (Continued)

• Resource Commitment With-the progress made on refining task scope and program details, a Restart Budget for 1987 was provided to the Board.

Approval was received in December. Site staffing levels are stabilized. Staffing and expense trends are consistent with budget estimates. Efforts are being expanded to identify i

permanent managers before April-1. NRC has voiced their strong preference that permanent key personnel be functioning in their respective-positions before Restart permission is given.

• Schedule Restart.of the reactor and low power operation beginning the second quarter calendar year 1987. Physics testing will precede power operation. Some tests at power will be conducted in July and August.

SUMMARY

Restart efforts are progressing as detailed within the Action Plan.

Progress is being made and activity is apparent everywhere at Rancho Seco. The NRC, and other industry agencies, are working closely with us to insure that our commitments meet their needs and will l support a safe and timely restart.

II. INTRODUCTION This report highlights the progress in implementing the " Action Plan for Performance Improvement" at the Rancho Seco Nuclear Generating Station. The Action Plan was submitted to the NRC on July 3, 1986, l

Amendment 2 on December. 15, 1986, Amendment 3 on February 28, 1987.

. This report covers the month of February, 1987.

III. ACTION PLAN PROGRESS

1. Chanaes and Revision to the Action Plan The expanded System Review and Test Program (SRTP) is now functioning with assigned Systems Engineers for each system.

The SRTP consolidates-the input from the Plant Performance and Management Improvement Program (PP&MIP) with the system reviews performed by the Systems Engineer and develops a systems testing program to demonstrate plant material readiness.

2. New Issues Affecting Restart Weekly program reports are prepared by the DGM Nuclear and submitted to a broad distribution including the District's General Manager. New issues which could impact the restart are identified in those reports and are summarized below.

• Duke Power Company's Oconee Nuclear Station has had two reactor coolant pump failures. Rancho Seco has the reactor coolant pumps made by the same manufacturer. We are evaluating the problem to see if Rancho Seco's pumps could experience the same kind of failure. It is believed that Rancho Seco does not have the same " root cause" problem, but we will continue to analyze this problem area. Plans are under consideration to add special instrumentation to monitor the pumps as they are operated during restart.

• Although diminishing in potential, the issue of the reliability of electrical power and control cables to be actually installed according to the separation criteria of the code of Federal Regulations Appendix "R" continues to require investment of resources. The discovered problems have been minimal, feeding optimism that this issue will not delay restart. 243 cables are being " walked down" to resolve this issue. To date, only 11 minor problems have surfaced.

• The refurbishment of 173 motor-operated valves presents significant challenges as regards identifying and obtaining required spare parts. Sources for parts are limited and valve operators show no standardization in configuration even though they come'from the same .

manufacturer. A review of this program to assign priorities for completion is underway. Some valves in non-safety applications may be deferred until a subsequent outage.

3. Closure of Issues l

l The QCI-12 Tracking System (QTS), a computer based tracking system, will document the successful development of. closure packages. Future revisions or Amendments to the Action Plan will indicate the completed actions as Amendment 3 did.

4. Systematic Assessment Program This program provides the input to the QCI-12 " Plant Performance and Management Improvement Program" (PP&MIP). The program is essentially complete, as shown in the following discussion of each input area.

a. December 26. 1985 Event Analysis ,

A total of 150 analyses, studies, repairs, and modifications were initiated to investigate and recover  !

from the overcooling event. These resulted in )

approxinately 400 recommendations, which have been .

identified in ,the Action Plan by the respective managers l and system engineers for closure. l

b. Precursor Review Approximately 1396 documents, applicable to Rancho Seco, have been reviewed to determine the appropriateness of previous reviews and implementing actions. These also are reflected in management and system-related work lists enumerated in of the Action Plan.

c. Deterministic Failure Consequence Analysis This portion of the program generated Action Plan items which will be closed before Restart. These analyses documented the effect of component failure on system operation, as well as synergistic effects upon other systems. 1232 recommendations resulted.

d. Personnel Interviews Interviews with plant personnel resulted in 1631 recommendations and generated actions to be completed prior to restart.

e. BWOG The program inputs are 76 recommendations of an expected 150 to 200. The remaining inputs will be evaluated according to our QCI-12 process in the near-future when officially received.

5. Management. Operations and Administration

a. Changes in Supervisory and Management Staff:

Efforts are continuing to identify permanent SMUD Managers for every key position. Both NRC and SMUD realize the importance of employing these managers prior to 09 start so that they may function as a cohesive team before the contractor managers depart. Interviews for all contractor-filled positions will be conducted in March 1987.

III.' ACTION PLAN PROGRESS (Continued)

b. Changes in Organizational Structure:

Efforts are in full stride to define the " Ultimate" or target nuclear organization which will result in the staffing of all nuclear management positions by SMUD people.

[ c. The Systems Review and Test. Program (STRP):

1 Total staffing for this organization is 110 people. All are presently assigned and all key positions have been filled.

Recent indications are that the NRC is increasingly concerned with the slow progress of the test program.

Strong corrective action is being initiated to expedite this vital task.

6. Plant Modifications and Maintenance Imorovements Section 4C of the Action Plan details the modifications and maintenance required for restart. Actual work is underway on each of the identified projects. Completion of each task is occurring, and-item closecut is through the QTS and closecut documentation process.

The Action Plan describes the SMUD program and plan for scheduling near term and long term recommendations.

7. Systems Review and Test Program This program is described in Section 40 of the Action Plan and is rapidly becoming the comprehensive effort envisioned in the Plan. As noted above, the program is now 100% staffed.

Implementation of the programmatic structure has been initiated. In addition, the detailed system review documents are completed. These will define the scope and depth of the individual system tests. Detailed test procedures are being developed. Approximately 30% are complete.

8. Non-Action Plan Related Activities The Foothills Fault is being investigated for its possible influence on Rancho Seco seismic design criteria. We do not expect that this study Gill result in any impact upon the plant design bases.

III. ACTION PLAN PROGRESS (Continued)

9. Resource Commitments and Utilization As a part of the expansion necessary to support the Action Plan, implementation programs have been strengthened or put in place to provide management information and control of activities and resources. These efforts allow for the budgeting and allocation of resources where necessary to accomplish the commitments of the Action Plan. The major elements are:

a. Personnel and Staffing During the month of February, 1987, the total staff assigned to the Nuclear Organization increased by approximately 20 people as efforts to staff up to accomplish action plan commitments continued. As of the end of January, there were 880 SMUD employees and 1751 consultant /other contractors assigned to the nuclear organization with a small number of SMUD and consultant personnel assigned to various locations other than Rancho Seco.

Approximate overtime utilization of the staff during the month of February as a percentage of straight time hours worked is as follows:

SMUD 22%

Craft Labor 15%

Consultants /Other Contractors 18%

(located at Rancho Seco and

. submitting site timesheets)

As of February 28, 1987, a total of 2,650 people were directly supporting Rancho Seco and the restart effort.

On a typical day-shift, approximately 2,000 people are physically present within the security fence. This has required staggering of working schedules and has created an office space shortage requiring utilization of over 50 temporary trailers.

10. Schedule At present we expect the plant to be producing power in the third quarter 1987. There exists potential for delay due to:

a. Unresolved problems with motor-operated valves.

b. Cable routing problems

c. Failures durin'g system tests

d. Delays in the regulatory process
