The Control Room Ventilation Systei was demonstrated to be within design values and,independent-of the Technical Support Center (TSC,) prior to the restart of: the uni b. 86-25-02 (closed): Adocumentationreview of,nontonformances (NCR S01-P-2570, NCR S01-P-2691) and their clos ut (CWO 4006-70, MO 85071243000), did not identify any frconsistencies or improprieties in theresolution and disposition of these nonconformances.. CFR Part 21 Repofts for Trahsamerica DeLaival Inc. (TDI) Diesel Generator The inspector reviewed dotumentation associ'ated with the inspection, testing and maintenance of.the TDI diesel's and discussed the status of the owners group recommendations with the cognizant-engineer and owners group representatiy Phase II of the,owners'group recommendatiohs has now been completed for both Unit 1 TDI diesels (# 1 and 2).
The two Part 21 reports which are currently open for the 'TDI diesels are:
a. TDI #132, November 6, 1986, Problem: Intake and Exhaust spring fa lu e potential
Resolution:
Replace with qualified springs Schedule: Four to six months as parts are available b. TDI # 136, 'Ju y 2, 1986 Problem: Insufficient torquing to connecting rod boltin Res6lution: Torque per new TDI' procedures (pending)
Schedule: -indeterminate 4. Outstanding TMI (NUREG-0737) Issues Units 2 and' Item I.D.2 SPDS (closed): -The SPOS function is performed by the Critical Function Monitoring System (CFMS).and the Qualified Safety Parameter Display System (QSPDS) which 'contains those parameters that are seismically qualified. The 'CFMS and QSPDS have been tested and.verif'ed at Units 2 and 3. These systems have been modeled on the plant. specifi& simulator and are being used by licensee personnel during trainin Item II-..F.2 (closed):
This item was partially closed-out in IR#
5O-361/85 13.,.Now that the Heated Junction Thermocouple installation has been completed, instrumentation for detection of inadequate core coolingis-completed. The.Subcooli ng Margin Monitor (SMM) has, been'removed from the vertical control boards. This was the result of 'a humaIn factors engineering study which concluded that it was redundant to the SMM available on the seismically qualified QSPDS.

A team inspection reviewing the environmental qualification program at the San Onofre units-1, 2; and 3 identified five noncompliances in their inspection report (50-206/85-30, 50-361/85-29, 50-362/85-28) that were later issued as violations. This report also identified that "no generic documentation deficiencies were found."
Corrective action identified in the. licensee's May 9, 1986 response t the Notice of, Violat.ion issued'by Region V NRC on April 2, 1986 was reviewed.by the inspector and. closed as follows:
a. GaliteCabfe (losed): 'The' licensee contacted the manufacturer and verified the simiTarity betweenthe Galite and Prestol-ite process
.
for applying insulation material. to conductor Firewall EP Cable (closed):. The licensee obtained an additional test report supporting the conclusion that Firewal EP cable is qualified for use at San Onofre Unit c. Target Rock Sol.enoid'Valves(closed)." The licensee revised the alified-life calculations for nine valves, based on a fication of valve energization status, following the EQ team inspectio Rockbestos-Firewall III Cable(closed):
The licensee obtained test data for Rockbestos Firewall III cable. This data supports the conclusion that Firewall III cable is qualified for use.at San Onofre units 1, 2., and e. Honeywell Transducer (closed):
The licensee maintains that the qualification package.was in errorwhen it specified a steam environment. The NRC maintains that the package was in error because the equipment was qualified by-analysis instead of type testin which would have been required if it was subject to a steam environment as indicated. The licensee agrees that type testing would have been required if the equipment was subject to a steam.:
environment. The equipment is qualified, no further action is require.
Exit Interview The inspection team met with representatives (denoted'in paragraph 1)on September*5, 1986. The~scope-andfindings of the inspection, which were discussed during this meeting are summarized -s set forth in paragraphs 1 through 5 of this report.
