schedule of required surveillances. The surveillance schedules continued i

to be departmentalized. Collectively they do represent a master schedule, although in different formats. The licensee is attempting to obtain the administrative support for a uniform master schedule. This item will remain open pending completion of this effor (Closed) Open Item (295/84025-03) Operation of Unit I with Loop A nominal Tavg 2 F below normal. Region III requested assistance from the Office of Nuclear Reactor Regulation (NRR) with respect to three aspects of this issue: Ensure " double-bookkeeping" of " generic margin" does not occu Evaluate " generic margin" with respect to 10CFR50.5 Confirmation of Westinghouse calculations and conclusion .

i j NRR provided the requested assistance and documented the effort in a Safety Evaluation Report (SER) issued June 27, 1985. The SER addressed each of the above issues and concluded that Commonwealth Edison's treat-ment of these issues was acceptable. NRR also points out that should the situation occur again a new and current analysis should be performed

for the new occurrence. The inspector has reviewed the Safety Evaluation Report and concurs with its conclusions. The licensee's efforts to identify and correct the cause of 2 temperature deviation have been successful to date. The licensee has therefore obtained an analysis from Westinghouse which concludes that the available Departure from Nucleate Boiling Ratio margins for the previous cycle (8) were unchanged by the reload and that operation in Cycle 9 with this condition is permissibl An onsite review of the Westinghouse analysis was conducted on June 12,

1985. The inspector has no additional questions at this tim No violations or deviations were identifie . Summary of Operations Unit 1 Unit 1 operated at full power levels throughout the inspection perio Unit 2 Unit 2 operated at power levels as high as 93% at the beginning of the inspection period and is currently in coastdown in preparation for a refueling outag At 6:25 a.m. on July 18, 1985, the licensee declared the 28 diesel generator (DG) inoperable af ter it had tripped on an overspeed condition thereby placing the unit in a four hour action requirement to be in hot shutdown as required by Technical Specifications. An Unusual Event was declared at this tim Prior to t' 2B DG tripping, the 2B Residual Heat Removal (RHR) pump had been taken out of service for replacement of the lower motor bearin Technical Specification 4.8.3.C requires that when one of the two RHR pump systems is inoperable the remaining RHR system, both centrifugal charging pumps and safety injection pumps and associated standby AC and DC power supplies, be demonstrated to be operable immediately and daily thereafte Technical Specifications states further that if the conditions cannot be met, the reactor shall be brought to hot shutdown in four hours.

, At 7:46 AM, July 18,1985, the 2B DG was declared operab'le after suc-

'

cessful completion of a surveillance test and the Unusual Event was terminate .

. Operational Safety Verification and Engineered Safety Features System Walkdown The inspectors observed control room operations, reviewed 4pplicable logs and conducted discussions with control room operators from July 2 through August 5, 1985. During these discussions and observations, the inspec-tors ascertained that the operators were alert, fully cognizant of plant conditions, attentive to changes in those conditions, and took prompt action when appropriate. The inspectors verified the operability of selected emergency systems, reviewed tagout records and verified proper return to service of affected components. Tours of the auxiliary and turbine buildings were conducted to observe plant equipment conditions including potential fire hazards, fluid leaks, and excessive vibrations and to verify that maintenance requests had been initiated for equipment in need of maintenanc The inspectors, by observation and direct interview, verified that the physical security activities were being implemented in accordance with the station security pla The inspectors observed plant housekeeping / cleanliness conditions and verified implementation of radiation protection control From July 2 through August 5, 1985,'the inspectors walked down the accessible portions of the component cooling, auxiliary feedwater and service water systems to verify operability. The inspectors also witnessed portions of the radio-active waste system controls associated with radwaste shipments and barrelin These reviews and observations were conducted to verify that facility operations were in conformance with the requirements established under Technical Specifications, 10 CFR and administrative procedure No violations or deviations were identifie . Monthly Surveillance Observation The inspector observed Technical Specifications required surveillance testing on the service water, chemical and volume control system, and residual heat removal systems and verified that testing was performed in accordance with adequate procedures, the test instrumentation was cali-brated, that limiting conditions for operation were met, that removal and restoration of the affected components were accomplished, that test results conformed with Technical Specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personne The inspector also witnessed portions of the following test activities:

During inspection of the missed quarterly surveillance of Unit 1 and 2 containment atmosphere monitors (SPINGS), problems with implementation of the modification which installed the SPINGS were -identified. These and other problems had already been documented on two discrepancy records (DR). Correction of these items will be tracked as an Open Item .

Open Items Open Items are matters which have been discussed with the licensee which will be reviewed further by the inspector and which involve some action on the part of the NRC or licensee or both. Two open items disclosed during this inspection are discussed in paragraph . Exit Interview The inspectors met with licensee representatives (denoted in Paragraph 1)

throughout the inspection period and at the conclusion of the inspection on August 5, 1985 to summarize the scope and findings of the inspection activities. The licensee acknowledged the inspectors' comments. The inspector also discussed the likely informational content of the inspec-tion report with regard to documents or processes reviewed by the inspector during the inspection. The licensee did not identify any such documents or processes as proprietar At the exit interview, the inspectors noted that station housekeeping had improved in the auxiliary building and crib house. The inspectors also noted that the station's intention to implement the company's Total Job Management system appeared to constitute a considerable improvement in both job planning and material histor i
