Selected Chemistry Logs Selected Tagouts Health Physics Watch Log 3.2 The inspector conducted routine entries into the protected areas of the plants, including the control rooms, Auxiliary Building, fuel buildings, and containments (when access is possible).
During the inspection activities, discussions were held with operators, technicians (HP & I&C), mechanics, supervisors, and plant managemen The purpose of the inspection was to affirm the licensee's commitments and compliance with 10 CFR, Technical Specifications, and Administrative Procedure (1)
On a daily basis, particular attention was directed to the following areas:
Instrumentation and recorder traces for abnormalities; Adherence to LC0 1s directly observable from the control room;
---
Proper control room shift manning and access control; Verification of the status of control room annunciators that are in alarm; Proper use of procedures; Review of logs to obtain plant conditions; and, Verification of surveillance testing for timely completio w'
(2)
On a weekly basis, the inspector confirmed the operability of selected ESF trains by:
Verifying that accessible valves in the flow path were in the correct positions; Verifying that power supplies and breakers were in the correct positions; Verifying that de-energized portions of these systems*
were de-energized as identified by Technical Specifications; Visually inspecting major components for leakage, lubrication, vibration, cooling water supply, and general operating conditions; and, Visually inspecting instrumentation, where possible, for proper operability. *
(3)
On a biweekly basis, the inspector:
Verified the correct application of a tagout to a safety-related system; Observed a shift turnover; Reviewed the sampling program including the liquid and gaseous effluents; Verified that radiation protection and controls were properly established; Verified that the physical security plan was being implemented; Reviewed licensee-identified problem areas; and, Verified selected portions of containment isolation 1 ijleU.3 Inspector Comments/Findings:
The inspector selected phases of the units operation to determine compliance with the NRC's regulation The inspector determined that the areas inspected and the licensee's actions did not constitute a health and safety hazard to the public or plant personne The following are noteworthy areas the inspector researched in depth:
- 6 Unit 1 Unit 1 began this report period at 97% with #3 governor valve and its isolation valve shut for overspeed protectio The unit operated at 97% power until March 21 at 9:58 p.m., when the unit was brought off the line to enter a planned refueling outag The outage has been scheduled for 45 days and is intended to accomplish the 6th refueling, replacement of three moisture separator reheaters, upgrade of the condensate pumps, perform 45 design changes, and reduce the backlog of outage related maintenance work request The inspector reviewed the following document with regard to the reactor cavity sea Procedure FP-PSE-R6 Section 9. Placement of Cavity Seal 11 Westinghouse Procedure for Refueling Cycle 6-7 After an inspection with regard to the installation of the cavity seal the inspector determined that:
A new seal with proper certification was placed into the cavit Proper QA hold points were use An inspection for leakage was performe The procedure was SORC approved (Meeting #86-018).
The procedure and installation of the seal satisfied the concerns of Bulletin 84-03, 11 Refueling Cavity Water Seal.
The i~spector had no further questions concerning the in.stallation of the cavity sea.
Unit 2 Unit 2 operated at 100% power throughout this period except for minor power alterations for testin No violations were identifie * Plant Tour During a tour of the licensee's Radiochemistry laboratory on March 11, 1986, the inspector identified several discrepancies concerning laboratory quality control practice The inspector observed the following:
approximately one-half (nine of a sample of nineteen) of the laboratory chemicals did not have expiration dates entered on the shelf life stickers located on each bottle three stock standards that had expired (according to their shelf life labels) *and eight instances where these standards were used past the expiration date to prepare spectrophotometric calibration standards The licensee's chemistry quality control program requires shelf lives be affixed to standards and reagents and expiration dates be assigned to reagents subject to evaporation, contamination, or decompositio However, several licensee chemistry personnel stated that either individual analytical procedures, the consultant material safety and shelf life program or an apparently undocumented general shelf life policy (one year for opened bottles, two years for unopened bottles) can be used to determine chemical shelf live The inspector noted to the licensee that the above controls are conflicting and the licensee's chemistry administrative or analytical procedures do not define the policy or program that should be used or takes precedenc In addition, the licensee's chemistry quality control program states that chemicals should not be used after their expiration date Comparison of lot numbers of expired chemical stock standards with lot numbers recorded in the laboratory notebook indicated that the expired chemical standard had been used by the licensee to prepare spectrophotometric calibration standard Collectively the above is a violation (272/86-06-01).
The licensee's chemistry quality control program requires that a performance..check of the conductivity bridge galvanometer be perforrrred quarterly before the cell constant is determine The licensee's computer tracking system sends reminder cards to the chemistry section when the checks are du The inspector observed two conductivity bridges with calibration stickers indicating past due electrical check Interviews with licensee chemistry and training personnel, and review of the conductivity analytical procedure indicate that the electrical check is incorporated in the analytical procedure and is no longer performed as a separate check as delineated by the quality control progra The licensee stated that a newer model conductivity bridge permits the check to be performed more simply
11 *
and quickly, and results in the check being performed more frequent1y than quarterl The expired calibration stickers were left over from the previous method of check control and were removed by the licensee on March 12, 198 The licensee plans to update the quality control program and computer tracking system to reflect current practice The inspector had no further question The licensee's chemistry quality control program requires that calibration curves be checked quarterl The inspector observed a spectrophotometric hydrazine one centimeter cell calibration curve which had an expired calibration date in the licensee's laboratory noteboo The licensee informed the inspector that normally the current calibration curves are kept in the front of the notebook, while expired curves are retained in the back for trend evaluatio The expired curves are usually marked in large letters 11 Do not use - expired.
The licensee marked the expired curve and put it in the back of the noteboo The inspector verified that the licensee had a current hydrazine one centimeter cell calibration curv The inspector had no further concern One violation was identifie.
Maintenance Observations During this report period an inspection into the maintenance area was conducted by regional based inspector (Combined Inspection 50-272/86-10 and 311/86-10) Surveillance Observations During this inspection period, the inspector reviewed in-progress surveillance testing as well as completed surveillance package The inspector verified that the surveillances were performed in accordance with licensee approved procedures and NRC regulation The inspector also verified that the instruments used were within calibration tolerances and that qualified technicians performed the surveillance The following surveillances were reviewed:

On several occassions beginning on March 14, 1986, a worker expressed concern regarding his safety and that of fellow workers during containment entries at powe The work crew had made several entries to inspect and repair various equipment in the fan cooler system inside containmen This work was accomplished with the reactor at power in the three week period preceding the start of a scheduled outage on March 23, 198 The specific concerns included the following:
neutron exposures were not properly monitored by the HP technician assigned to job coverage workers felt fatigued and developed skin rashes ALARA considerations should postpone the work until after reactor shutdown records were changed just prior to the outage On March 21, 1986 a region based radiation specialist investigated the workers concern The inspector obtained information from:
Interviews with the Station Superintendent, Health Physics and Chemistry Manager, Nuclear Fire and Safety Manager, Maintenance Manager, and associated staff personne A review of completed radiation work permits, radiation surveys and associated record A containment entry at power,tours of all elevations, and comparison ~gamma and neutron dose rates with recorded value A review of the Nuclear Department Safety Manual requirements in regards to containment entrie Findings and Conclusions The radiological conditions in the work areas inside containment were properly monitored and assesse In general, the gamma and neutron dose rates were in the order of 10 mrem per hour, the airborne and l
. 13 surface contamination were below limits except in isolated aiea The whole body dose estimated from field readings and entered on the RWP indicated that workers received only a few millrem per entr Both TLD and neutron dosimetry were specified on the RW Start of job surveys were performed and continuous HP technician coverage was provided during wor The licensee's primary safety concern was heat stress of the worker The ambient temperature on the 130' elevation can exceed 100 degrees The safety department advised that special apparel is available such as vortex coolers and ice vest Stay times are limited according to the maximum work area temperature as specified in the Safety Manua Both workers and line supervisors are briefed regarding these precaution The licensee advised that this work, part of an Engineering directive and preventative maintenance program for service water, was not postponed until the outage since a thorough management review indicated that no adverse personnel safety condition was presen The plant maintenance organization was recently directed to perform any preventive maintenance, corrective maintenance or generic replacements at convenient times if not prevented by personnel safety concern During this inspection the licensee was in the process of transferring the radiation work permit system from a manual to a computerized syste In addition, a new main control point was being implemented with much improved facilitie There was no attempt to alter record The inspector concluded that all aspects of this allegation were unsubstantiate As a result of this allegation and after discussions with the resident inspector, the licensee's management has reiterated their open door policy to all PSE&G personnel and contractors and have stated that they are willing to discuss any potential concerns that arise during the course of the work being performed and will correct them where necessar The management also reiterated that if these concerns cannot be solved there is a resident inspector on site to discuss potential problem The resident-inspector has polled the principal contractors on site to ascertain that the lines of communication are open between the contractors and licensee management, and that radiological matters are being resolved quickl The resident inspector concluded that communication lines are open and that radiological matters are being resolve No violations were identifie ~.
