The following is the information requested by Harry Rood (NRC) per telecon on August 4, 1987.

1. Coov of all Maintenance Administration Procedures - Sent August 6,1987

2. Status of Technical orocedures All Maintenance Procedures required to support restart have been identified and incorporated into the overall Project Schedule. These procedures have individual completion dates to assure that the procedure is available prior to its need to support any testing of maintenance activity related to the startup effort. Below is a tabulation of the status of Maintenance procedures as of August 13, 1987.

1. Outstanding And # Outstanding Not

1. Approved Required for Restart Required for Restart Surveillance i Procedures 40 198 29 Maintenance i Procedures 30 38 36 l Electrical Procedures 86 8 10 Instrumentation l Procedures 59 36 43 1

3. Rforaanization and the Organizational Chart with Explanation of Chances I Past reorganizations have resulted in a Programs Group as an arm of the Maintenance Department. This group was established to provide single point accountability for the creation, implementation, and enhancement of all Department projects and procedures. Maintenance Engineering resources were mainly left in the production groups in order to solve day-to-day work related problems. With the expanded role of the Nuclear Engineering Department and the Plant Support Department, the need for direct Maintenance Engineering involvement has diminished. Because of this, the Maintenance Department has reorganized by removing all Engineering personnel from the production groups and assigning them to the programs group (see attached chart). This has allowed a more specific definition of the Maintenance Engineering role and a decrease in the contractor involvement in the programs groups.

4. Eragram Continuity with Reagrd to D. Army's Departure Dave Army's resignation will not change the overall direction or the degree of development planned for the Department or its programs. The entire development plan was based on industry standards adopted from INPO, EPRI, and regulatory guidelines; this will not change.

5.. Nucleis' Status

, The Nucleis work request control system went into the test phase mid-May 1987. Testing was completed and the system went to production the first-week of June 1987. The system has been in production since then and has performed well. Nucleis provides a variety of on-line reports and printouts making;information associated with backlog readily available to all organizations'.

i Hork requests are actually planned and printed through Nucleis. This not only makes the' data available, but ensures the data is accurate and detailed.

6. Calibration Proaram Status and Procedures to Ensure Gaality Implementation In order to ensure quality is maintained, all calibrations of measurement h and test equipment are done with overview by the Calibration Lab. Various satellite calibration facilities may perform calibrations, but the site standards are maintained by'the Calibration Lab.

Specific individual procedures are being written to perform calibration of measurement and test equipment. Currently more than eighty such "MTE" procedures exist. The generation of specific calibration procedures for measurement and test equipment will continue.

Additional emphasis will continue to be placed on tracking measurement and test equipment usage. Prior to startup, all use of measurement and test equipment will be tracked by work request or other suitable means.

I.011 is not used for calibration of measurement and test equipment.

I.011 is still used for the calibration of some process instrumentation.

More than fifty specific procedures exist for process instrumentation ,

calibration at this time. Prior to startup, I.011 will be replaced with more appropriate procedures to ensure process instrumentation is calibrated properly. The use of specific calibration procedures for process instrumentation, along with up-to-date procedural guidance for all plant instrumentation, will ensure quality is maintained.

7. Hork Reauests.Bactica Status: Number of Restart Work Rgauests and their l Trends The work request backlog at the time of the last NRR visit was approximately 5200. Of these, 3300 work requests were required for restart.

The current backlog is approximately 2900 work requests. Of these,1800 are required for restart.

A work request required for restart affects the safe, legal or efficient operation or shutdown of the plant. Since some plant systems are operating and being tested, new work requests are written daily.

1

These new work requests receive an initial review by a Operations planner with licensed operator background.to determine its need for restart. The new work requests also receive a review from the Scheduling organization to determine the need for restart. The scheduling ~ supervisors are also 1 individuals with licensed operations backgrounds. f This process will continue throughout the startup and into power  ;

operations.

Because of this, the " Restart" work request backlog is dynamic.

The progress in the backlog can be attributed to a highly detailed planning and scheduling process that ties all required work by work request number to plant and schedule milestones. This level of planning and scheduling was not in place prior to the spring of 1987. With these tools, and a new level of accountability now possible, backlog reduction has bmn accomplished. He are confident that all restart work request: 'can be completed prior to restart without impacting schedules.

8. Personnel Training in New Proarams Formal. training has been scheduled and completed on the Maintenance Administrative Procedures (MAPS) with approximately 100 of 250 maintenance personnel as of August 13, 1987. The remainder of the personnel are scheduled to complete the training in the near future.

9. Maintenance Trainina in General: Number of Trainina Personnel Dedicated to Accreditation There are a number of specific skilled training personnel dedicated to the Maintenance training effort. The status as of August 13, 1987, is as follows:

Number of Personnel Assigned Responsibility 1/2 Training Superintendent Technical 1/2 Tool Repair Instructor 4 I&C Instructors <

2 Electrical Technician Instructors 3 Mechanical Maintenance Instructors 1 Building Maintenance Instructors 4 2 Electrical Maintenance Instructors 1/2 Technical Staff Manager 4 Technical Staff Instructors 1/2 Accreditation Specialist 1 1/2 Accreditation Technician i

l The initial INPO review of the Maintenance Training Accreditation Program accrued in May 1987. From this review some additional items were identified tnat required modification and/or addition to the program as originally defined. This resulted in the development of an action plan and schedule to monitor progress to completion. As of August 13, 1987, this performance schedule is on track and the activities are being accomplished on schedule. The completion date for all the identified items is October, after which INP0 will return for the final review of the Maintenance Training Program.

10. Valve Proaram Status. Manual and Remotelv Ooerated Valvn A. Manual Valves The selection criteria for the manual valve program is completed and included in MAP 009. l Manual valves may receive lubrication, inspection and cycling.

Cateaor.y_.1  !

Valves identified as being mandatory for inclusion into a PM Program.

The purpose of these valves is to ensure nuclear plant safety. These valves are required for a safe controlled shutdown of the plant, ,

maintenance of the plant within the shutdown window, placing of the plant in cold shutdown and maintaining it there, and also to mitigate the consequences of a radiological release. Furthermore, these are operational valves that are manually stroked during normal or defined emergency conditions. These are not equipment isolation, maintenance type valves. The selection criteria used to identify these valves are:

• valves identified in Casualty and Emergency Procedures a SFAS stand-by valve lineups as identified in AP.4 CatAgory 2 Grouc 6: Valves are in QA Class 1 Systems not included in Category 1 and are 1 2 1/2" in size. Valves are those that could have an impact on system process flows and are 121/2" in size.

Group B: Valves identified by good engineering judgement as to whether or not they should be entered into the PM Program. Their inclusion is not mandatory. The selection criteria for these valves is economic, and selection for inclusion into the PM program is on an individual basis. These are the valves that, if failed, could have a financial impact by reducing power operation or affecting surface or airborne contamination levels within the plant. The selection criteria used to identify these valves are:

• SP.214.01 " Inservice Testing and Inspection of Valves" a valves identified as having high failure rates - equipment history

• non-isolatable valves

• locked open and closed valves (SP.214.03)

• maintenance valves that isolate major equipment a valves in Boric Acid Systems L

,.4 Category 3 Valves not' entered into the PM program.because they are seldom used n and do not impact nuclear safety or have economic considerations.

Deficiencies identified with these valves will be' repaired on corrective maintenance ~ work requests.

, All 'fothe Category 1 manual valve PM tasks will.b~e developed and

?' performed prior to startup.: This effort is currently in progress and is. integrated into the Project Restart Schedule.

B. Motor Operated-Valves 9 The selection criteria for the MOV Program is completed and included in MAP 009.

General PM ' guidelines include predictive maintenance *, Motor Operated Valve Analysis Test System (MOVATS) lube change out, stem lube,.

acoustic monitoring, ILRT. evaluation, stroke timing and packing replacement.

Categorv1 Those valves requiring surveillance by Section XI of the ASME code as determined by Engineering.

Categorv 2l All other motor operated valves.

All of the Category 1 MOV PM tasks will be developed and performed prior to startup.. This effort is currently in progress and is integrated into the Project Restart Schedule.

C. Air l0perated Valves The selection criteria for A0V PM program is completed and included in MAP 009.

General PM guidelines' include stroke time, acoustical monitoring, lubrication, and LLRT evaluation.

Cateaorv 1 Those valves requiring surveillance by Section XI of the ASME code as determined by Engineering.

• Predictive Maintenance activities involve continuous or periodic monitoring and diagnosis in order to forecast equipment failure.

l Cateaorv 3 All air operators not included in Category 1 or 2.

The A0V PM tasks will be developed per the vendor's recommendation.

This effort is currently ongoing for all Category 1 valves. This will be completed prior to startup, as will the performance of the individual PM tasks on all' Category 1 valves above. The performance i of these tasks will be integrated into the Project Restart Schedule.

Valve Program Summary All of the Category 1 manual and motor operated valves have been refurbished under specific action programs outside the PM program. The remaining actions are to include the followup task into the PM program to  ;

ensure the continued operability of these components. As stated above, this action is scheduled and being tracked and will be complete prior to restart.
