13. System Safety Committee Reviews (Surry 1 and 2)

Unresolved Item 76-16/3 concerning System Nuclear Safety and Opera-ting Committee reviews of reportable occurrences was inspected. The inspector reviewed committee minutes dated July 28, October 29, and December 28, 1976, and noted that the required reviews had been made. This item is closed.

14. Flooding of Safety-Related Equipment From Non-Category I' Seismic)

Sources (Surry 1 and 2) The inspector reviewed the status of completion of a design change to prevent the flooding of safety-related equipment sufficient to prevent a safe shutdown of the plant. Design change 74-55, "Flood Control," embodies commitments made to the commission in a December 30, 1974, VEPCO response to an October 31, 1974, NRR request for an

e IE Rpt. Nos. 50-280/77-2 and 50-281/77-2 analysis of the potential for this type of accident at Surry. Design change 74-55 consists of seven appendices which are listed. Appendix A - Circ Water Expansion Joint Shields (12/Unit) Appendix B - Concrete Dikes (4 locations) Appendix C - Circ Water Flood Trips Appendix D - Flood Control - Fire Protection System Appendix E - Flood Control - MISC Controls Appendix F - Flood Control - Additional Controls Appendix G - Additional Alarms The first six appendices have been completed. The remaining Appendix G consists of the installation of level switches in vital areas with remote indication in the control room.

15. Pressurizer Level Setpoints (Surry 2)

VEPCO Reportable Occurrence Report No. USRE-S2-76-06, dated May 27, 1976, describes an event relating to high pressurizer level trip setpoints that had drifted in the unconservative direction. The inspector verified that the long term action on changing the setpoint two percent in the conservative direction was performed. The high level trip setpoint was changed from 90% to 88%. The low level engineered safeguards actuation was changed from 7% to 9% on both units. Both changes moved the setpoint in a conservative direction. This item is closed.

16. Station Nuclear Safety and Operating Committee Minutes IE Report 50-280/76-11 and 50-281/76-11 discussed the need for improvements in SNSOC meeting minutes.

The inspector had no further questions.

IE Rpt. Nos. 50-280/77-2 and 50-281/77-2 18. Review of Safety Limits, Limiting Safety System Setting, and Limiting Conditions for Operation (Surry 1 and 2) Reactor operations were reviewed in order to ascertain whether Technical Specification requirements for safety limits, limiting safety system settings, and limiting conditions for operation are being adhered too. The examination consisted of direct observation of process instrumentation, consoles, panels, and annunciator boards. The inspector also reviewed records, logs, charts and held discussions with operators on shift. Approximately fifteen (15) parameters which have Technical Specification limiting values were selected at random and checked for conformance to required values. Systems affected included the reactor coolant system, control rod system, turbine system, containment system, safety injection system, spray system, and emergency power system. Within the areas inspected, the inspector had no further questions.}}
