Management Meeting On November 29, 1989, a Management Meeting was held in the Region V
Office in Walnut Creek, California with the individuals identified in Paragraph 1. The purpose of this meeting was to discuss issues related to the failure of an ASCO solenoid valve on August 23, 1989 and recent operator performance problems. In addition, the licensee provided a status on enhancements to the Emergency Preparedness and Root Cause Assessment Programs, engineering program improvements, the Design Basis Documentation (DBD) review, and activities of Nuclear Oversight Organization The meeting convened at 10:00 Introduction Mr. Martin opened by stating that the purpose of the meeting was to review recent concerns and to assess the progress of program initiatives since the last Management Meetin Slides used during the licensee's presentations are enclosed.as an attachment to this repor Mr. Ray began by identifying actions being taken in response to the June 27, 1989 Management Meeting. In particular, he indicated that
Southern California Edison (SCE) has placed specific emphasis in the following areas:
-
Enhanced training of all personnel
-
Reduction in the backlog of work items
-
Consolidation and enhancement of the Root Cause Assessment Program
-
Evaluation for necessary qualified staff resources in all areas
-
Maintenance of positive progress toward goals in the Nuclear Engineering, Safety, and Licensing Organization Failure of the ASCO solenoid for CV-304 Mr. Caldwell introduced this topic by noting that on August 23, 1989, an Automatic Switch Company (ASCO) solenoid valve operator for CV-304, the normal charging valve in Unit 1, failed, rendering CV-304 inoperabl This issue was discussed in special Inspection Report No. 50-206/89-3 Valve CV-304 is required to be closed for hot leg recirculation (HLR)
when it is necessary to prevent boron precipitation in the core in the event of a loss of coolant accident (LOCA).
Mr. Caldwell briefly summarized the history surrounding the failure of this solenoid, the apparentiroot cause of the failure, and the number of weaknesses found in the corrective action program that were associated with this issu Mr. Caldwell further noted that when CV-304 failed, the licensee entered a 72-hour administrative action to fix the valve or initiate a plant shutdown. This was done since SCE did not believe that the Technical Specifications (TS) were applicable to the HLR flowpath, since it had been added to the plant in 198 However, the NRC considered that when CV-304 failed, TS 3.3.1 was applicable. In the absence of a specific action statement concerning this valve, TS 3.0.3 would have required that a plant shutdown be initiated within one hour of the valve failur The licensee agreed with the NRC's characterization of the problems surrounding the failure of CV-304 and the interpretation of the TS requirements for this valve. SCE representatives also stated that the company is committed to conservative implementation of TS requirements and would consult with the NRC as necessary to ensure conservative implementation in the futur Mr. Martin stated that this issue was being discussed to ensure that future situations do not arise in which TS interpretations compound issues when activities (such as engineering reviews) find problems in the plan Operator Performance Problems Mr. Johnson summarized recent performance problems observed in the Operations area. In particular, a number of events have taken place that were attributable to training (insufficient emphasis on routine plant operations) or to a need for additional formality in the performance of routine duties. The most recent of these-events included (1) a partial draindown of approximately 700 gallons of water from the reactor coolant system due to operation of the wrong valve and (2) failure to recognize
that a test conducted in Unit 2 rendered one of the Unit 3 off-site AC power sources-(via a cross-tie breaker) inoperabl Mr. Morgan responded that SCE had been closely monitoring performance problems that have occurred and were not merely reacting to NRC concerns in this area when they initiated their review. The licensee believed that these recent problems were due to training weaknesses; insufficient formality; and performance, design, and human factors problems, with the two most significant causes being training difficulties and lack of formality in the performance of normal activities. Mr. Morgan indicated that they were attempting to reduce the number of performance errors through various means, including the Formality, Attention to Detail, Communications, and Teamwork (FACT) program, professional operator development, and simulator improvements. The licensee also indicated that they were evaluating other potential factors for performance problems such as the use of extensive overtime during outages and operator morale. Long term actions would then be implemented based upon the results of these evaluation Mr. Martin stated that there was a perception on the part of the NRC that Operations performance has not recently been as strong as in previous years. He encouraged SCE to make program adjustments as necessary to prevent continued perceptions of a decreasing trend in the Operations are Program Enhancements SCE provided a status on enhancements to the Emergency Preparedness and Root Cause Assessment Programs. In addition, engineering program improvements, the DBD review, and the activities of Nuclear Oversight Organizations were also summarized. Slides used by the licensee during these presentations are provided as an enclosure to this repor Closing Remarks Mr. Martin stated that he considered this to have been a useful session, and indicated that efforts to implement program improvements appeared to be going as well as could be expected. He noted that licensee management appeared to share NRC perceptions about recent trends in Operations performance. He emphasized that the NRC did not want to overemphasize recent operator performance errors; however, it is desirable that any perceived adverse performance trend be reverse The meeting adjourned at 2:00" OPERATIONAL EVENTS CAUSE CATEGORIES EVENTS TRAINING

QA CONCERN
Management Meeting - November 29, 1989 SCE Has Reviewed the NRC and SCE Memoranda Concerning the June 27 Meeting
- Actions Are Being Taken in Accordance With That Discussion Agenda for Today Includes Items of Concern to SCE As Well As the NRC
- Of Particular Concern Are Efforts to Maintain Operational Excellence U -Overall SCE Assessment, Based on Last 3 Months There Is a Need to Increase Training In All Areas, Both "How-To" and
"Why", With Emphasis on Excellence In Normal Operations
-
Thereis a Need to Reduce the Backlog of Work in Both Technical and Related Program Areas There is a Need to Consolidate and Enhance Root Cause Determination Processes Action Is Required to Maintain and Increase Qualified Staff Resources Significant, Positive Progress Has Been Made Toward Our Goals, Including Much Greater Involvement In--and Awareness Of--Ongoing Plant Activities by NES&L
Application of Technical Specification Requirements U Conservatively Implement Requirements At All Times
Inform Region V and Consult With NRR When Clarification Is Required to Ensure Conservative Implementation
Where Functions or Components Have Been Added and/or Taken Credit For Subsequent to Issuance of the Relevant Technical Specification Requirements, Include These Functions or Components Within the Requirements
.
Propose Changes Where Necessary to Clarify Applicability
Emergency Preparedness Program
SCE Has Included Emergency Classification Among the Responsibilities of the Emergency Coordinator
This Worked Well So Long As the Emergency Coordinator Remained In the Technical Support Center (TSC)
When SCE Decided to Transfer the Emergency Coordinator Function to the Emergency Operations Facility (EOF) Following Its Activation, Emergency Classification Was Slow
- Region V Comment in Connection With 1988 Exercise
In 1989 Exercise, SCE Attempted to Duplicate TSC Emergency Classification Timing at the EOF
- Results Successful With Respect to Timing
- Other EOF Functions Adversely Impacted
SCE Will Modify Its Program to Retain Emergency Classification in the TSC Following Emergency Coordinator Transfer to the EOF
Result Will Improve the Interface Between the EOF and TSC
Root Cause Assessment Program I
Need for SCE Reassessment Discussed by NRC at the June 27 Management Meeting
SCE Has Been Strongly Oriented Toward the Principle that the Most Effective Corrective Action Results When Root Cause is Determined by the Organization Responsible for Implementing the Action
-
This Remains an Important Factor in Our Development of a Revised Program
-
Nevertheless, We Must Pull Together Scattered Activities Into a Single Program Which Must Be Developed
Root Cause Assessment Program
The Program Will Be Administered by Oversight Engineering, Within the Nuclear Oversight Division of NES&L
-
Dr. Chlu Will Be the Manager of Oversight Engineering Effective 1/1/90
- The Program Will Be Fully Functional by 6/1/90
-
Root Cause Program Staff to be Engineers Drawn from Quality Organization - Additional Staff Will Be Hired If Needed
-
In Addition to Root Cause Program Group, Oversight Engineering Will Include Quality Engineering, Independent Safety Engineering Group and Nuclear Safety Group
Root Cause Assessment Program
The Program Will Provide for:
-
Systematic Oversight of All Root Cause Determinations by the Program Staff - This Will Include Tracking to Provide Visibility to Timeliness and Backlog
-
Independent Root Cause Determinations by Oversight Engineering for Designated Events or Conditions
-
Establishment of Ad Hoc Evaluation Teams When Directed by the Manager of Oversight Engineering
-
Systematic Evaluation of Data to Identify Conditions by the Manager of Oversight Engineering
-
Definition and Training In the Use of the Appropriate Methodology to be Applied to Root Cause Determinations In Various Circumstances
