Regulatory Conflicts in Regard to 1 Operability of Appendix "R" System .

This item involved conflicting regulatory requirements concerning I i shutdown cooling primary containment isolation valve RHR-M0-17. The l l review was conducted by the NRC office of Nuclear Reactor Regulation (NRR). Results of the review were documented in a letter from NRR to Resident Inspector, Cooper Nuclear Station (CNS), dated .

l October 14, 1987. The NRC project manager for CNS stated that '

RHR-M0-17 while in its normal de-energized position, is capable of j performing its required safety function and is therefore operabl RHR-M0-17 being operable, the licensee is not required to log the position of RHR-M0-18 dail This item is close (Closed) Open Item 298/8704-01: Shelf for Procedures and Prioritization of Valve Lineup This item involved the prioritization of valve lineups in Emergenc Procedure (EP)5.4.3.2, " Post-Fire Shutdown to Cold Shutdown Outside Control Room," and the installation of a' shelf for procedures in the alternate shutdown room. Corrective actions included the following: ,

4. Monthly Maintenance Observation  !

Station maintenance activities of safety-related systems and components were observed and reviewed by the NRC inspectors to verify that they were l conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with Technical Specification The following maintenance activities were observed and reviewed: 1 i

October 20-23, 1987: WorkItem(WI) 872614 "RHR Service Water Booster Pump D," dated August 14, 1987 using Maintenance Procedure (MP) 7.2.14,

Operational Safety Verification The NRC inspectors observed operational activities throughout the inspection period. Control room activities and conduct were observed to be well controlled, Proper control room staffing was maintaine Discussions with operators determined that they were cognizant of plant status and understood the importance of and reason for each lit annunciator. The NRC inspectors observed selected shift turnover meetings and noted that information concerning plant status was properly communicated to the oncoming operator Maintenance requests were reviewed to verify that appropriate priority was assigned and that the maintenance was performed in a timely manne Tours of accessible areas at the facility were conducted to confirm operability of. plant equipment including the fire suppression systems and other emergency equipment. Controls were adequate to ensure a safe working environment. Facility operations were performed in accordance

No violations or deviations were identified in this are . Radiological Protection Observations o

'

The NRC inspectors verified that selected activities of the licensee's radiological protection program were implemented in conformance with facility policies, procedures, and regulatory requirements. The NRC inspectors verified that radiation work permits contained the appropriate information to ensure work was performed in a safe and controlled manner; personnel in radiation controlled areas (RCA) were wearing the . required personnel monitoring equipment and protective clothing; radiation and/or contaminated areas were properly posted and controlled based on the activity levels within the area; and radiation monitors were being properly utilized to check for contaminatio No violations or deviations were identifie . Security The NRC inspectors observed security personnel perform their duties of vehicle, personnel and package search. Vehicles were and escorted or controlled within the protected area (properly authorizedPA). The had adequate illumination and and the isolation zones were free of transient material. Compensatory measures were implemented in a timely manner when equipment failed. These observations verified that the physical security plan was being implemented in accordance with the requirements established in the CNS Operating Licens No violations or deviations were identified in this are . Exit Interview An exit interview was conducted on October 30, 1987, with licensee representatives (identified in paragraph 1).
