Unresolved Items 5.
Unresolved items were not identified during this inspectio Surveillance Testing (61701)
The inspectors reviewed the licensee's surveillance test program for the mainsteam and pressurizer safety valves to ensure that functional testing is in accordance with regulatory requirements and industry guides or standard The inspection consisted of discussions with responsible
licensee engineers, review of the test procedures, and evaluation of data obtained during the last performance of the testing for Unit 1, May -
June 1986. Testing of the valves was conducted in accdrdance with ASME,Section XI, IWV-3500, In-service Testing of Category C valves and ANSI/
ASME PTC-25.3.-197 Testing of the pressurizer safety valves was conducted in accordance with licensee* procedures 1-PT-12, 1-ST-1884, 1-ST-1888, and 1-ST-188 The testing and refurbishment of the valves was accomplished by Wyle Laboratories and is documented in Test Report No. 48332-0 dated June 24,
.198 The mainsteam safety valve (MSRVs) setpoints are tested in place using a Consolidated Hydroset Uni The tests were conducted on all*15 MSRVs in accordance with licensee procedures 1-PT-13.1, 1-PT-13.2, and 1-PT-1 The inspector considered the licensee 1s program for testing the pressurizer and mainsteam safety valves to be adequat No violations or deviations were identified in the area inspecte.
Spent Fuel Pool Activities (86700)
The inspectors reviewed OP-4.1, the Controlling Procedure for Refueling, Unit 2, October - November 1986.. The procedtire was reviewed to ensure the following: A limitation on the number of fuel assemblies that can be out of safe geometry locations at the same tim Provisions for verifying prior to fuel handling that the spent fuel pit area crane interlocks on physical stops will prevent the crane from passing over fuel storage location Provisions for verifying prior to field handling that spent fuel pool area ventilation system is operabl Provisions for verifying that the spent fuel storage area isolation occurs during a high radiation signa Provisions for verifying that minimum water level requirements are monitored during fuel handling activitie Provisions for verifying that the spent fuel pool storage area radiation and airborne radioactivity monitors are operabl No violations or deviations were identified in the area inspecte **
3 Modification Testing (72701)
The inspectors reviewed three design change work packages to determine if appropriate testing had been performed (DC 85-18 Unit 1 and 2 Service Water Motor Operated Butterfly Valve Project; DC 85-25 Unit 1 and 2 Feed Water Heater Replacement; and DC 84-61 Unit 1 and 2 HP Heater Drain Pump Discharge Pipfng and Valve Replacement).
The following testing was verified, and based on a limited review was found to be properly documented and in conformance with regulatory requirements and industry-approved codes and standards: Ultra-sonic testing of welds, Magnetic particle testing of welds, In-service leak tests (visual inspection of welds), Instrument loop functional checkout, Instrument leak test, Electrical insulation test, Relief and safety valve verification (actual lift pressure v expected), Flush (drain system), and Hydrostatic testing of new and/or reinstalled piping on tubeside of feedwater heater No violations or deviations were identified in the areas inspecte.

Potential Failure of Multiple ECCS Pumps Due to Single Failure of Air Operated Valve in Minimum Flow Recirculation Lin The licensee reviewed IEB 86-03 and has identified, per Surry Serial
- 86-6778 dated January 15, 1987, that the specific concern of IEB 86-03 is not applicable because the minimum flow recirculation valves are motor operate Motor operated valves fail as-is, whereas air operated valves fail shu However, licensee investigations of IEB 86-03 raised a concern regarding the possible failure of recirculation valves to reopen upon demand after having been shut in accordance with procedure Further analysis by the licensee has shown that this concern can be addressed through appropriate revision in applicable Emergency Operating Procedures (EOP's).
The following EDP' s were reviewed by the inspectors and were found to contain appropriate rev1s1ons to address the possible failure of recirculation valves to reopen:
EP-0.01, Rev. 1.01 11 Rediagnosis 11 EP-1.00, Rev. 1.02 11 Reactor Trip/Safety Injection 11 EP-2.00, Rev. 1.01 11 Loss of Reactor or Secondary Coolant 11 EP-4. 00, Rev. 1. 01 11 Steam Generator Tube Rupture 11 ECA-3.01, Rev. 1.01 11Uncontrolled Depressurization of All Steam Generators

Motor Operated Valve Common Mode Failures During Plant Transients Due to Improper Switch Setting The *inspectors held discussions with responsible licensee and MOVATS engineers and maintenance personnel concerning the progress of their program to meet the requirements of the bulleti The licensee has completed the testing on all _Bulletin valves and is currently in the process of data evaluatio The inspectors reviewed the documentation associated with the following MOVs:
FW-151A, FW-1518, FW-151C, FW-151D, FW-151E, FW-151F, FW-251A, FW-2518, FW-251C, FW-251D, FW-251E, CH-2267A, CH-22678, CH-2269A, CH-2270A, CH-22708, LCV-21158, LCV-2115C, LCV-2115D, LCV-2115E, RC-1535, and RC-153 Review of the data showed that the licensee identified and corrected the following general deficiencies: the 11as found 11 torque and limit switches not within the target value; excessive spring pa.ck gap; grease migration into the spring pack; faulty torque and limit switches; improperly staked stem nuts; missing dust cover screws; damaged gaskets; separated grease; excessive grease; i nsuffi ci ent greased; and damaged declutch lever key The inspectors also discussed with the licensee the surveillance and tracking procedures used to identify specific motor operated valves to be retested or afforded special attention at a later date (during plant outages or periodic maintenance) as a result of initial MOVATS testin MOVATS testing can provide indications of potential performance degradation due to normal valve operatio The licensee now tracks valves to be more closely scrutinized at a later opportunity through observation of previous testing documentatio The licensee is currently automating all motor operated valve maintenance and testing tracking procedures such that these valves will be identified to receive special attention during periodic maintenance and testin No violations or deviations were identified in the areas inspecte.
