Management Interviews The scope and findings were summarized on a weekly basis with those persons indicated in Paragraph 1 abov.
Licensee Action on Previous Inspection Findings (Closed) Noncompliance (280/79-15-01): Failure to Follow Annunciator Alarm Procedure lA-6 The inspector verified that the operators were reinstruc-ted to log important alarms and events and to provide more detailed shift turnover Annunciator alarm procedure lA-62 has been revise (Closed) Noncompliance (280/79-15-02) Unsealed and Unattended Fire Barrier Penetration The inspector verified that the penetrations were sealed, that personnel were reinstructed on the procedure requirements, and that additional administrative controls were established for these activitie.
Unresolved Items Unresolved items were not identified during this inspectio.
Unit 2 Steam Generator Replacement Activities The inspector reviewed certain U-2 SG replacement and associated activities to verify that the activities were performed in accordance with the Steam
-2-Generator Repair Program (SGRP) and the Engineering Task Assignment (ETA)
procedure Within the areas inspected, no items of noncompliance were identifie The review included the following activities: The removal of steam generator "C" from containment to the storage facility on May 6, 1979, and the subsequent removal of SG "B" and "A".
Before lifting the SG, the lift rig was examined and load tested to verify crane/rig operabilit The review of plant chemistry records indicated unusual volumes of low pH radioactive solutions in the Unit 2 containment sump and the liquid waste systems on April 16, 1979, and a few days afterwards the source of the solutions was determined to be the Chem-Nuclear Systems decon-tamination process for the reactor coolant system (RCS) pipin The process acidic rinse water was apparently released to the Unit 2 floor drain and sump, and the radwaste syste Inspections and samples indicated that the solution was not introduced into the containment recirculation sump, which was isolate The rinse water was retrieved and is being stored in barrels for processin The licensee stated -
that additional controls would be established on the decontamination process with revision of the operating procedure attachment to the ETA and that systems exposed to the acidic solution would be reviewed to verify no deterioration is expected to occu Chemical certification records on the phosphoric and nitric acids used are being sent to the station to be included in the documentation record When completed, the procedures, reviews, and records will be inspected (Open item 281/79-49-01). The inspector reviewed records and the corrective actions concern-ing the release of several gallons of contaminated water from U-2 RWST to the Unit 2 Steam Safeguards Buildin Some of the water was released to the pad area outside the building entranc Inunediate corrective action was taken to restrict and cleanup the affected area The leaking valve which led to the release through a vent is being repaire.
Unit 1 Operations Surry Unit 1 has been shutdown since March 15, 1979, following the issuance of the NRC Order to Show Cause concerning the potential piping stress analyses deficiencie The inspector toured the control room and certain Unit 1 plant areas to verify that the shutdown operations were in accor-dance with the Technical Specifications and facility procedure Plant logs and records were also reviewe Within the areas inspected, no items of noncompliance were identifie Specific areas of inspection included: Followup on a plugged boric acid line to the RCS; alternate boration lines were available as required by TS 3. t.
- e-3-Followup on the boric acid filters on the boric acid flat beneath the boric acid tanks in the auxiliary buildin Although lead shielding was installed on the filters, radiation fields of up to 500 MR/hr were observed in the restricted area near the filter The licensee is evaluating the filter.change history to determine if more frequent filter changeout can reduce the radiation levels (Open item 280/79-31-01).
The inspector reviewed periodic test 15, "Steam Generator Auxiliary Feedwater Pumps", which is performed monthly, to verify that the FW pump discharge isolation valves are properly restored following re-circulation flow testing of the pump Normal valve line-up is re-stored and verified in PT 1 The inspector verified that the reactor control rooms were adequately staffe New Fuel Assembly Damage On May 7, 1979, while conducting routine inspections of the new fuel for Unit 2, the licensee discovered that impur~ sodium hydroxide had been poured onto 62 of 64 new fuel assemblies stored in the fuel buildin The FBI is currently conducting an investigation of the incident, and inspec-tions by NRC Security Inspectors are in progres The licensee and site security personnel have implemented increased security and access control measures for the fuel buildin The new fuel assemblies are being returned to Westinghouse for examination and repair as necessar Annual Site Emergency Drill On June 1, 1979, the inspector and D. J. Perrotti of Region II witnessed the annual site emergency dril On and off-site personnel and agencies were appropriately notifie Changes to the EPIP's are being made by the licensee as a result of certain deficiencies identified by the licensee during the drill. Additional discussion on the drill is available in IE Inspection Report Nos. 50-280/79-27 and 50-281/79-44.
