ATTN: 0. R. Lee, Vice President Electric Production P. 0. Box 840 Denver, Colorado 80201 Dear Mr. Lee: This refers to the Management Conference conducted in the Region IV offices on November 14, 1984, to review the major conclusions of NRC's October 1984 Assessment Report, to discuss operations of the Fort St. Vrain facility and to review outstanding licensing actions. Since this conference there have been a number of technical meetings with your staff and you have submitted a substantial amount of information pertaining to the matters that were discussed. We have also carried out a number of related inspections. Based on a detailed review of records related to issues raised in the Assessment Report and on follow-up inspection effort, we have concluded that no violations of NRC requirements were identified therein. However, there are two matters which must be brought to your attention. As we discussed with you and members of your staff on several different occasions, it is possible to come to an ambiguous interpretation of 10 CFR 50.72 concerning whether the failure of six control rods to automatically insert during the scram event which occurred on June 23, 1984, should have been reported at the time of the initial report to the NRC Operations Center. You should emphasize to your operations staff that it is the intent of this regulation that any known condition involving potentially serious degradation of a component or system required for plant safety be reported at the time an event notification is made pursuant to 10 CFR 50.72. Likewise, your training programs and plant procedures should be clear on this point. Section 4.2.5.6 (page 4-8) of the Assessment Report discusses your program for verification of the correct performance of operating activities. (TMI Action Plan Requirements , NUREG-0737, item 1.C.6. ) Your position on implementation of this item was apparently accepted without sufficient consideration to the need for double verification of system or equipment status, particularly in connection with maintenance activities. You should review your procedures 851158 h,J n-N TC D../ ha Public Service Company of Colorado -2- with this in mind and assure that you implement a system of "double verification" to the maximum extend practicable in view of the design of your plant. Your response to this item should be provided within 120 days of the date of this letter. If you have any questions concerning this letter, we will be pleased to discuss this with you. Sincerely, E.

Box 840 Denver, Colorado 80201 Facility Name: Fort St. Vrain Nuclear Generating Station Conference Conducted: November 14, 1985 Report prepared by: R. E. Ireland, Chief, Special Projects and if/tie Engineering Section Approved: m'4\' ≥ S/21 I4c E. H. Johnson, Chief, Reactor Projects Branch 1 Date Conference Summary A management conference was held at the NRC Region IV offices in Arlington, Texas, on November 14, 1984, with officials of the Public Service Company of Colorado to discuss a number of issues related to restart and continued operation of the Fort St. Vrain Nuclear Generating Station (FSV). The discussions covered (a) the major conclusions of NRC' s October 1984 Assessment Report transmitted to PSC on October 16, 1984, by the Director, Office of Nuclear Reactor Regulation, (b) NRC perspectives on management and operation of the FSV facility, and (c) current licensing items. The slides used during these discussions are attached to this report. Results: The licensee stated that the Public Service Company of Colorado will do whatever is necessary to correct any outstanding problems and that the company will apply those resources necessary to put the facility in a safe and reliable operating condition. The NRC staff stated that, in addition to issues already identified, the problems with the reserve shutdown system and the control rod suspension cables would have to be resolved prior to restart of the -2- reactor. The staff also stated that it had not yet determined whether any specific enforcement actions would be taken as a result of the problems identified in the assessment report. Further inspection effort would be needed to make this determination. It was emphasized that NRC would need a documented commitment from the licensee, in the near future, which could be used to form the basis for scheduling and planning those NRC inspection and technical review activities which would be necessary in connection with supporting a decision to allow the facility to resume power operations. The licensee agreed that such information would be provided. The NRC staff stated that PSC should consider the Assessment Report as examples of NRC findings that warrant attention but not as a necessarily complete compilation. Each of the Assessment Report actions that would need to be completed prior to restart was briefly summarized. It was emphasized that PSC would need to provide timely and complete documentation for review by NRC with respect to each of these actions if delays were to be avoided owing to the need for NRC to request additional information. It was agreed that a meeting between PSC and NRC technical staff should be scheduled in the near future to discuss actions in greater detail . With respect to ongoing licensing actions, the staff emphasized that PSC should see early resolution of matters related to the PCRV tendons and that the work related to fire protection issues (Appendix R) should get moving. It was noted that PSC has the lead on resolving technical questions in connection with LC0 4. 1.9 and that PSC should either commit to carryout the 100% load rejection test or justify why it need not be done. With respect to Building 10 structural design criteria and electrical modifications, the staff stated that further review was to be done. A number of items concerning plant management, plant operations and PSC/NRC communication, were discussed. It was agreed the scope and schedule for the management review being carried out for PSC by the NUS Corporation would be submitted for NRC comment in the immediate future. PSC also agreed that NUS should submit its reports to NRC and PSC simultaneously. PSC' s schedule and plans for implementation of any recommendations would be submitted soon thereafter. With respect to improvement in communications between PSC and NRC, the staff stated that openness and candor were need to assure that misunderstandings do not occur regarding identification of requirements which must be met and the nature and relevance of commitments made by PSC in meeting those requirements. It was stated that, if misunderstandings do arise, they should be brought to NRC management attention so that clear, singular resolution could be achieved. The staff stated that the forthcoming management audit and the resolution of technical issues could be separated. -3- It was agreed by NRC and PSC that there would be need for additional meetings at both technical and management levels to assure that problems needing resolution are clearly defined and answered and that schedules are established. The staff stated that its inspection activities would likely be increased to follow PSC activities prior to resumption of reactor operations. Persons Participating in the Conference: NRC: RIV: R. D.
