.* Denotes attendees at exit management . meeting on December 5,198 ~ Follow-up of Previous Identified Environmental Qualification (EQ)

Inspection Findings-Eight open/ unresolved items identified in EQ Team Inspection Report (50-206/85-30,150-361/85-29, and 50-362/85-28) are addressed below: (Closed) Item 50-206/85-30-5 ASCO Solenoid Valve Coil Housing Covered with Heavy Rust ASCO solenoid valve, plant tag No. SV-3201, EQ Document Package M 38292, Revision 1 (Unit 1) - During the plant physical inspection, this valve, located in the Turbine Building and exposed to outside air, was found to be covered with heavy rust to the extent that the integrity of the coil housing could not be established. Prior to the_ exit meeting, the licensee initiated a Site Problem Report and an Engineering Evaluation, with a seven-day deadline scheduled for-the latte The inspector reviewed Site Problem Report IU857120 and Maintenance Order 8509199900 In November 1985, solenoid valve SV-3201 was disassembled, inspected and reassembled. The solenoid coil was determined to be in good operating condition. The solenoid housing was wire brushed and painted.

~

approximately 200 craftspeople and maintenance planners were given EQ training during the last quarterLof ca'lendar year 1985 and.the-first quarter of 1986. The Lesson Plan TI-2A08 E/Q for QA and Q personnel has;recently been approved and the training is scheduled to start in January 1987. Review of records has verified that-Q personnel have' received EQ training on MOVs and Raychem splices during the past nine months. The upgrading of the training program s provides acceptable assurance that those concerned with environmental qualified equipment are trained in this are This item is close No violations or deviations were identifie (Closed) Items 50-361/85-29-5 and 50-362/85-28-5, EQ Condition Monitoring (EQCM) Program License condition 2.C(5)c for Units 2/3 requires, " Prior to startup following the.first refueling outage, SCE shall provide affirmatio :of implementation of the improved surveillance program procedures."

Accordingly, a program to monitor the condition of EQ electrical equipment was established by station procedure S0123-I-1.32. This procedure defined responsibilities and provided instructions for-evaluation of EQ equipment performance, including comparison of actual field degradation to the laboratory predicted lifetime Concurrent with the EQCM program, the licensee has established an

" Environmental Data Acquisition" support activity to be used for formulating environmental baselines of selected plant area Special Operation and Maintenance Support procedure S123-SPOMS-4 provides the guidance for collecting the required environmental dat As neither the EQCM or Environmental Data Acquisition programs were-in a stage of full implementation at the time of the NRC team inspection, this item remained ope The_ Environmental Data Acquisition Program was implemented in October.1985 to establish environmental baselines for 17 selected plant areas at Units 2 and 3. Temperature, humidity and radiation data were collected monthly.for a twelve-month period for the 17 selected areas in each plant in accordance with S123-SPOMS-4. The

. 3 inspector audited the data collected for the months of October 1985, January 1986, May 1986, and October 1986. The collected data appeared consistent with what one might expect for the plant areas selecte The collected data were forwarded to Nuclear Systems Engineerin This data was=used for a preliminary review that compared those environmental conditions found with the assumed conditions on which initial ~ estimated electrical equipment lifetimes were based. A more detailed study in this area is presently in proces The EQCM Program was initiated June 1984 for Unit 1 and October 1984 for Units 2/3. The frequency of surveillance has been established as the refueling cycle. The limited data available for pump motors, valves, fans and instrument transmitters were examined by the inspector. The inspector also examined O&M support procedure S0123-XVII-5.2.2, " Condition Monitoring Program," which supersedes station procedure S0123-I-1.3 It is concluded that the Environmental Data Acquisition and EQCM Programs have been fully implemented since the NRC team inspection in September 198 This item is close No violations or deviations were identifie , E (Closed) Item 50-362/85-28-6 ASCO Solenoid Valve, Cable Entrance Not Sealed ASCO Solenoid Valve, plant tag No. 3HY-9823-1, EQ Document Package M 37703 (Unit 3) - The EQ Equipment Maintenance Information Sheet listed this valve along with others subject to a pressurized moisture environment and thus requiring sealing of the cable entrance. During the plant physical inspection, no cable entrance seal was observed. Design Change Package No. 3-6419.0E dated April 2, 1985, covered installation of a Conax seal but had not yet been t implemented. When questioned, the licensee stated that this

- solenoid valve, which controls an air-operated containment purge / isolation valve, need only be de-energized to perform its safety-related isolation function. Since moisture intrusion at the cable entrance cannot affect that function, the NRC team inspectors agreed that a cable entrance seal is not required for EQ purposes, even though installing the seal may be good engineering practic The inspector examined a document change notice EQCN-1 dated July 30, 1986, to revise EQ Document Package M 37703, and verified the package had been revised to identify those ASCO solenoid valves which required conduit moisture seals. The solenoid (9823) in question was called out in the QC Document Package as not requiring conduit moisture seal The inspector examined design change package 3-6419.0E which required installation of Conax electrical conductor seal assemblies

identified during the plant physical inspection of the Unit 2 AFW pump motors. Pump motor P504 exhibited an Allis-Chalmer manufacturer's label, although the EQ Document Package identified Siemens-Allis.as the manufacture The inspector. examined a letter received from Siemens-Allis dated October'2, 1985, which identified the four AFW pump motors and stated, "Siemens-Allis is the corporate name for all electrical products manufactured by Allis-Chalmers. This name change occurred-in-1978."

The inspector also verified that EQ Document Package M 37632 had been revised to clarify Siemens-Allis/Allis-Chalmers as the

, manufacturer of the AFW pump motor This item is close No violations or deviations were identifie (Closed) Item 50-206/85-30-8, 50-361/85-29-7, 50-362/85-28-7; AFW Pump Motor Start Duty Limits Permissible pump start duty limits stated on the pump motors and in the EQ file were not specified in the station operating

'

instructions. For the AFW pumps this was corrected by prompt licensee revision of Operating Instruction SO:3-2-4, " Auxiliary Feedwater System Operation." Generically, the station staff initiated an investigation to ensure that all safety-related pump

. motor.. start duty limits are adequately addressed in station operating instructions.

f

, The inspector examined documentation for SOCR Item 8504791 task 004 (Units 2/3) and SOCR 850411 Task 11 (Unit 1) which requested the review of station operating instructions, and where appropriate, the inclusion'in the instructions of proper directions pertaining to

. pump motor start duty limits. Task 004 for Units 2/3 was compl*ted November 27, 1986. The scheduled completion of Task 11 for Unit 1 is the end of December 198 This item is closed.

specify whether or not a specific component requires a seal.

The inspector examined EQ Document Packages M 38292 (ASCO Solenoid

f LThe inspector examined an inter-office memorandum to Procurement-Engineering-from Nuclear Engineering dated November 18, 1986.that alerted Procurement Engineering of the deficiency regarding the

, - procurement of EQ replacement components / spare parts for Units 1, 2,

- and.3. Because of the time lapse between the EQ inspection-(September 1985) 'and the date of the memorandum, the licensee agreed , 1

.to demonstrate that no EQ replacement component / spare parts had been purchased to the outdated requirements during the interim period by reviewing procurement records for this perio The licensee prepared a summary of his findings from the procurement review which was forwarded to Region V as Tables 1 (Unit 1) and 2-(Units 2/3) attached to the licensee's letter dated December 18,
