I I. HIGHLIGHTS

• A comprehensive " Restart Scope" list was prepared and sent to ,

-i NRC.

• The new TDI diesels were prepared for their 100 hour0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> _run tests and began prerequisites for their "35 consecutive starts" test.

• Cabinet testing was completed on the Emergency Feedwater- u Initiation and Control system (EFIC). A portable test _ console was connected to dynamically test the various panels and  !

cabinets.

• A total of 495 NRC "Open Items" (specific action items identified during NRC inspections) were known in April. . Of the 495 identified items only 181 remained open on April 30.

• Efferts. continued to resolve the ' entire cable raceway issue.  ;

As a conservative measure, 241 cables will be " walked down" to- .J determine whether they are physically located as designed. i 7 cables remain to be inspected. fi e Resource Commitment Site staffing levels.have been dropped to 2497. Staffing and expense trends are consistent with budget estimates. Efforts-are being expanded to identify all permanent managers before .

May 31. The new AGMs and an Acting Nuclear Licensing Manager have been named.

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 supp r t a safe and timely Restart.

I 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, Amendment 2 on December 15, 1986 and Amendment 3 on February 28, i 1987. This report covers the month of April, 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 theLinput 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.

The Action Plan is being used as a source document or " Subset" of a comprehensive Restart List assembled by Implementation.

This document was transmitted to NRC April 19, 1987..

2. New-Issues Affectina Restart

• A total of 243 cables were " walked down" to determine proper design location. 7 cables remain to be inspected.

• The reliability of 107 motor operated (MOVs) valves continues to be an important issue. .The plan is to refurbish 31 MOVs during the decay heat outage.

3. Systematic Assessment Proaram 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 approximately 400 recommendations, which have been identified in the Action Plan by.the respective managers and system engineers for closure,

b. Precursor Review A total of 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 the Action Plan.

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

officially received. ,

4. Manaaement. Ooerations and Administration i a

a. Changes in Supervisory and Management Staff:

Efforts are continuing to. identify permanent SMUD management individuals for every key position. Both NRC-and SMUD realize the importance of employing these managers prior to Restart so that they may function as a cohesive 1 team before_the contractor managers depart. At this time I George Coward and Joe Firlit have been. named permanent SMUD J Assistant General Managers. John Vinquist has been {

appointed the Acting Manager of Nuclear Licensing. .i Mr. Vinquist will act as Licensing Manager until the permanent SMUD manager is named. John Hard was replaced ,

as Deputy General Manager by G. Carl Andognini-who was. )

named Chief Executive Officer, Nuclear. .

b. Changes in Organizational Structure:

l Efforts are in full stride to implement the " Ultimate" or target nuclear organization by. staffing of all nuclear management positions with SMUD people.

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

Total staffing for this organization is 110 people. All positions have been filled.

5. Plant Modifications and Maintenance Imorovements Section 4C of the Action Plan details the modifications and i maintenance required for Restart. Actual work is underway on most of the identified projects.

III. ACTION PLAN PROGRESS (Continued)

6. 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. i Detailed test procedures are being developed; 95 are complete I and approved.

7. Non-Action Plan Related Activities l

The Foothills Fault is being investigated for its possible I influence on Rancho Seco seismic design criteria. He do not )

expect that this study will result in any impact upon the plant I design bases. The second phase contract has been let to Bechtel l Corporation to perform additional trenching.  !

8. Essource 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 improved 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 7 During the month of April,1987, the total staff assigned to the Nuclear Organization decreased by about 10%. On May 1, 1987, there were 896 SMUD employees and 1601 consultant /other contractors assigned to the nuclear j organization with a small number of SMUD and consultant i personnel assigned to various locations other than Rancho I Seco. l Approximate overtime utilization of the staff during the month of April as a percentage of straight time hours worked is as follows: i SMUD 11%

l Craft Labor 15% i Consultants /0ther Contractors 11% .

(located at Rancho Seco and I submitting site timesheets) )

1 As of May 1,1987, a total of 2,497 people were directly supporting Rancho Seco and the restart effort. On a i typical day-shift, approximately 1,900 people are i physically present within the security fence. This has  !

created an office space shortage requiring utilization of j over 50 temporary trailers. l b-
