,. ATTACHMENT 1 DISTRICT RESPONSE TO NRC INSPECTION 87-06

.- NAIJLE OF VIOLATION NRC Reauest for Clarification-The forwarding letter for Inspection Report 50-312/87-06 requested that the District, in the response to the Notice of Violation, discuss measures being taken to correct programmatic weaknesses observed in the QA program related to corrective action measures and weaknesses in the 10 CFR 50.72 and 10 CFR 50.73 reporting systems. In addition,.the letter also expressed a concern regarding preparation of the operating staff to operate the facility after an extended outage and-the need for providing all crews with an opportunity to exercise the new plant systems during the plant testing program. In our review of your response to the Notice of Violation of Inspection Report 50-312/87-06, we are unable to clearly identify your response to the requests of the report' cover letter.

Please provide us with further clarification on this subject.

District Resoonse to Item 1 i

The District has established a management process development and review program to establish control of management processes. Major management processes are reviewed by top level management to identify and to correct programmatic weaknesses on a weekly basis.

This program establishes the Management System Control Center (MSCC) Group to review the mechanics of plant management processes. If programmatic weaknesses are identified, the process owner is required to develop a comprehensive action plan to reestablish programmatic control of the process. The MSCC group determines the effectiveness of the corrective actions through the review and trending of appropriate quantitative or qualitative procets indicators.

The deficiency identification, reporting, and correction processes at Rancho Seco will undergo a rigorous programmatic review by the MSCC group to identify and to correct programmatic weaknesses in these processes.

The specific process breakdowns identified in NRC Inspection Report No.

50-312/87-06 will be included as data points in the review and evaluation of these processes by the MSCC Group. The District anticipates that ini-tial reviews of these processes will be accomplished by August 31, 1987.

This NOV will be reviewed by the Independent Investigation / Review Group.

Based on that review an appropriate investigation will be performed. The response to this NOV will be updated as required based on the results of this review or investigation.

,. District Resoonse to Item _2' In response to your expressed concern regarding preparation of the operating staff to operate the Rancho Seco plant after the current outage the following information is provided:

  • Each crew will receive extensive plant simulator training prior to plant restart (simulator training will include familiarization with the newly installed EFIC system).
  • System modifications implemented during the restart program have been identified. During the scheduling of Functional Testing of these .:

systems, the operating crews will be adjusted to ensure the involvement of as many operating crews and individuals as possible.

  • System tests involving the actual loss of a system or component will .

be run more than once if practical to provide an even greater opportunity for operator involvement and training. An example of these tests include Loss of ICS Test, Loss of NNI Test, and Remote Shutdown Test.

  • The scheduling of each test will be carefully coordinated with the ,

responsible system engineer to ensure that the tests are held in a time frame that will allow maximum operator participation.

In view of the ongoing operator systems training being held at Rancho Seco, simulator training, and the timely adjustment of system testing and operator schedules, the District has taken or is planning actions to alleviate the concerns of the NRC with regard to operator performance following this shutdown.
