Monthly Surveillance Observation (61726)

.The inspectors. selected and observed surveillance activities of safety-related systems, and. components to ascertain that these activities were conducted in accordance with technical specifications, limiting conditions for operations and other license requirement The inspectors observed portions of surveillance tests involving safety-related system The inspectors determined that the surveillance test procedure conformed to Technical Specifications (TS) requirements and verified that Limiting Conditions for Operations (LCOs).were met and that the surveillance test was completed at the required frequency. The inspectors also verified that the required administrative approvals and tagouts were obtained prior to initiating the test, or the testing was accomplished by qualified personnel in accordance with approved test procedures and that any required test instrumentation was properly calibrated. Upon completion of the testing, the inspectors observed that the recordeo test data was acetrate, complete and met TS requirements and verified that test discrepancies were corrected, and the systems were properly returned to service. The following specific surveillance activities were observed:

STP 147.001 - Reactor Building Penetration STP 601.003 - Boron Concentration of Refueling Canal MWR 85X0025 - Leak Test NI Detector Covers Within the areas inspected, no violations or deviations were identifie . Monthly Maintenance Observation (62703)

The inspectors observed maintenance activities of safety-related systems and components to ascertain that these activities were conducted in accordance with approved procedures, technical specifications (TS) and appropriate industry codes and standard The inspectors verified the following:

(a) activities were not violating limiting conditions for operations (LCOs);

(b) redundant components were operable; (c) the procedures used were adequate to control the activity; (d) QC hold points were established where required; (e) required administrative approvals and tagouts were obtained prior to work initiation; (f) proper radiological and appropriate ignition /

materials used were properly certified; (h) activities were accomplished by qualified personnel using approved procedures; and- (i) equipment was properly tested 'before being returned to servic Additionally, the inspectors reviewed several outstanding job orders to determine that the licensee was giving priority to safety-related maintenance and a backlog which might _ affect its performance was not developing on a given syste The.following specific maintenance activities were observed:

MMP 180-012 Diesel Generator Individual Cylinder Overhaul MWR 85M0424 Support for STP 409-001 Refueling Inspection MWR 85M0391 Turbine Inspection MWR 8501557 Repair Steam Leak MWR 85M0392 "A" Turbine Stop Valve Isolation MWR 85M0394 "A" Turbine Control Valve MRF 20388A&E Rework of Condensate Pumps to Change from Variable to Constant Speed MRF 20891C&E Staging Rotopeening Equipment in Reactor Building and Cable Penetration Within the areas inspected, no violations or deviations were identifie . Onsite followup of Events at Operating Reactors (93702)

On October 7, 1985 at 9:38 p.m. with the plant in Mode 5, a safety injection occurred during the performance of surveillance test procedure STP 125.011, Safeguards Activation Test. The solid state protection system (SSPS) was being aligned in preparation for closing reactor trip breakers. During this step in the procedure, the A train of the SSPS was taken out of test with all safety injection blocks inserted. When the B train was taken out of test, the pressurizer pressure low signal was inadvertently not blocked and since the reactor system was approximately 50 psi a safety injection resulted. All systems functioned as designed and the pressurizer level went from 70% to 80% on the cold calibrated pressurizer leve The injection

. lasted approximately three minutes before being manually terminated by the operato All - equipment was then returned to normal in approximately 20 minutes. An LER 85-028 is being prepared by the licensee at this time addressing cause and effect and corrective action This item will be addressed in a subsequent repor On October 26, 1985, the plant was in a refueling mode with the vessel defuele While performing Electrical Maintenance Procedure EMP 280-007 (preventive maintenance) a major loss of physical security effectiveness was experienced for approximately twenty-five minute Preventive maintenance was being performed on the 120 VDC (1HA) circuit breakers, normally supplied by Bus IDA via a battery charger or from Battery 1 Prior to the test, battery 1A was isolated with the circuit breaker (CB) cpened supplying Bus 1HA1, the undervoltage relay for Bus IDA was de-energized. When the CB reclosed the undervoltage relay condition initiated the blackout sequence The sequencer opened the incoming breaker to Bus IDA preparing the Bus for diesel generator (DG) A loading. Due to the DG A being out of service, Bus IDA remained de-enerized for 25 minute .. .

The licensee is continuing to pursue the cause and consequences of this event and is performing an evaluation of its impact on the plant. This event is identified as an unresolved item (50-395/85-39-01). pending completion of the licensee's evaluation of this even . Refueling Activities (60710)

The inspectors reviewed licensee progress to ascertain whether pre-refueling activities specified in the technical specifications (TS) have been completed and whether refueling activities are being conducted as required by TS or approved procedures. Specifically, the inspectors verified the following: (a) surveillance testing required by the TS and licensee procedures for fuel handling had been completed prior to the handling of fuel in the core; (b) the periodic testing of refueling related equipment was performed as required by TS or licensee administrative procedures; (c) shift manning for fuel handling operations (removal, inspection, sipping and insertion) and other ongoing activities met the requirements of TS and approved procedures; (d) containment integrity was maintained; and (e) main-tenance of good housekeeping ire the refueling are Additionally, the following STPs including work requests were witnessed /

Within the areas inspected, violations or deviations were identifie . ESF Syetem Walkdown (71710)

The inspectors verified the operability of engineered safety features (ESF)

systems by performing a walkdown of the accessible portions of the systems listed below. The inspectors confirmed that the licensee's system lineup procedures were consistent with plant drawings and the as-built configura-tio Specific equipment conditions and items that might degrade performance (e.g. , hangers and supports being operable and good house-keeping) were reviewed. Interiors of electrical and instrumentation cabinets were inspected for debris, loose material, jumpers, evidence of rodent The inspectors verified that valves, including instrumentation isolation valves, were in proper position, power was available, and valves were locked if require The inspectors compared both local and remote valve position indications for correctness.
