IE Bulletin 79-06A Revision 1 North Anna Power Station Unit Nos. I and 2
Dear Mr. O'Reilly:
Our letter of April 26, 1979, (Serial No. 274/041479), provided responses to items 1 through 13 of IE Bulletin 79-06A, " Review of Operational Errors and System Misalignments Identified During the Three Mile Island Incident." This letter provides addtional information on bulletin items 2, 3, 4, 7d, 8, 9, 10, 11, and 12 as requested by your staff. Item 2 The primary operator action required to prevent the formation of voids continues to be to insure the proper initiation and continuing performance of the engineered safety features equipment. Abnormal procedur AP-44, "Luss of Reactor Coolant Systea Pressure", was written to provide specific operator actions for this type of transient. Emergency procedures have been revised to provide guidance for insuring forced flow by verifying margin to saturation conditions and by observing reactor coolant pump amps, loop flow indications and loop delta T's. These procedures include specific precautions regarding maintenance of at least 50 F subcooling in the primary system. Item 3 The pressurier level bistables which input to safety injection initia-tion are placed in the trip mode by an Abnormal Procedure (AP). Trip status lights on the control board confirm that the action has been completed. Operating procedures will be revised by July 1, 1979 to include a verification that these bistables are in the trip mode prior to placing the unit in opera-tion. , Item 4 Containment isolation occurs automatically upon initiation of safety injection. Containment isolation also occurs manually from operator action. Technical Specifications Table 3-6-1 is attached. This table lists valves that receive a Containment Isolation signal, and describes the function of each valve. Slb 282

. vanum. Euanic 4 o Powns courm to Mr. James P. O'Reilly Page 2 Item 7d Specific parameters are: 1. Decreasing pressurizer pressure but not necessarily a decreasing pressurizer level.
- 2. Increasing pressurizer relief tank pressure, level, temperature, and pressurizer relief line high temperature.
- 3. Automatic Action.
- a. Pressurizer backup hea ;4 on
- b. PORV Isolation
- c. Reactor trip from Low Pressurizer Pressure (above P-7)
- d. Turbine Trip from Reactor Trip (above P-7)
- e. Sa fety Injection The applicable procedures have been cevised.
We are partic ws'ing, with other utilities, in a Westinghouse users group ef fort to review and improve all emergency and abnormal proce-dures based on lessons learned from the TMI incident. We will continue to revise and improve our procedures as part of this effort. Item 8 The review as requ; red by Bulletin item 8 was conducted by reviewing valve posit;,ns concurrently with those procedures that check or mani-pulate those valves. Thus, we believe we have performed the requested review. Additionally, North Anna Technical Specifications already contain re-quirements to check valve position for valves not locked, sealed or othe rwise maintained in position. We do not beliese the periodic surveillance of locked valves will significantly enhance valve align-ment verification. Furthermore, many of our valves are locked because of inaccessibility. Item 9 A review of Technical Specification Table 3.6-1 will provide the missing information to make our response complete. Item 10 As stated in our response, the Shift Supervisor is the authority level for removing and returning equipment for service. An example of equipment made inoperable for testing is the periodic testing of pumps. The test flow path is a recirculation path. Con-sequently, the normal discharge path is isolated. We do not believe this constitutes a significant problem and consider our initally proposed resolution to be acceptable. Our proposed resolution did require revision to appropriate procedures and they have been revised to imp!ement our proposal.

LOCA will be conducted with an anticipated completion date of July 31, 1979 and a scheduled completion date for final review of August 31, 1979.
