| contamination monitoring instruments out-of-servic See paragraph 5 for details, Decontamination Personnel - The ccntractor personnel assigned to decontamination duties in the auxiliary building were not performing all duties in a manner considered radiologically saf See paragraph 5 for detail General Employee Training Building Decontamination Showers - The licensee had not developed procedures for controlling, sampling, and discharging the contents from the decontamination shower holding tank. See paragraph 9 for details, Radiographic Work - The licensee needs to exercise more control over radiography work being performed onsite including surveys of incoming and released vehicles and equipment. See paragraph 10 for detail Wide Range Noble Gas Monitor (WRNG) Calibration Procedures - The licensee's procedure for WRNG monitor calibration referenced model numbers for the count rate meter and detector element. The recorded data for these devises was not consistent with the procedure. See paragraph 11 for detail Particulate and Iodine Plateout Studies - The licensee had not performed a plateout study for particulate and iodine on the WRNG monitors. See paragraph 11 for detail Job Preplanning - The C/RP and ALARA groups are not involved with job preplanning. See paragraph 5 for details.

| | |
| , Advanced Planning and Preparation The NRC inspectors reviewed the C/RP. organization and determined that the licensee had augmented the radiation protection group with contractor technicians. The liccnsee assigned 17 senior and 8 junior technicians to operational support, 2 senior technicians to ALARA, and 2 senior and 4 junior decontamination technicians to containment building decontamination-work. The licensee also contracted for 10 non-nuclear trained
| |
| . housekeeping personnel for cleanup and decontamination duties in the auxiliary building and 24 laundry workers. The licensee had established two 10 nour shifts with staggered working hours to provide 24-hour coverag The NRC inspectors reviewed the resumes and work histories of the contract senior technicians and determined that they met the recommendations of ANSI Standard N18.1-1971. The licensee had also evaluated the contractor technicians and provided site specific training and individual testing in accordance with Health Physics Procedure HP-16, " Selection of Contract Health Physics Technicians."

| The NRC inspectors were concerned that personnel assigned to cleanup and decontamination duties in the auxiliary building were not demonstrating work practices which were radiologically acceptable when handling contaminated radioactive material. The licensee stated they had initiated ,
| | DMB (IE06) |
| a training course to provide these individuals with a better understanding i of radiation and precautions for handling radioactive materia The licensee had obtained additional portable s.urvey instruments, personnel contamination monitors, and constant air sampling equipment prior to the refueling outage. The NRC inspectors expressed concern

| .
| | MIS System RIV File DRSP RSTS Operator RSB DWeiss, LFMB (AR-2015) |
| regarding the inoperability of a large quantity of dose rate survey instruments and personnel monitoring equipment. Although this inoperability of equipment created an inconvenience, the health and safety of personnel was not compromised. The licensee stated that an additional I&C technician had been assigned to radiological instrument repair and calibration and that should rectify this concer The NRC inspectors expressed concern that the C/RP and ALARA groups were not involved with job preplanning in the early development phase. The C/RP and ALARA groups were using daily briefings to update work on progress and delays in the outage schedule. Licensee representatives stated that on occasion, work was delayed because either ALARA reviews or radiation surveys were needed prior to starting work and that radiation work permits (RWPs) had been prepared for scheduled work that were not use No violations or deviations were identifie . Training and Qualifications The NRC inspectors reviewed the routine and specialized training programs associated with the outage with emphasis on that training provided to contractor personne The NRC inspectors determined that the requirements of 10 CFR Part 19.12 were being me The NRC inspectors noted that the licensee had received a full size mock-up of the bottom portion of a steam generator, including the tube plate, for training. The licensee nad used the mock-up to train personnel for eddy current testing and tube repair wor No violations or deviations were identifie . External Exposure Control The NRC inspectors reviewed the licensee's program for external radiation exposure control to determine compliance with the requirements of 10 CFR Parts 20.101, 20.102, and 20.20 ;

| The NRC inspectors determined that all personnel entering the radiation controlled area (RCA) were issued a thermoluminescent dosimeter (TLD)
| |
| which are processed monthly. The individual entering the RCA also wear direct-reading dosimeters (DRD) as required by the RWP. The licensee uses the DRD results for tracking personnel exposures with dose totals updates being made once per shif The NRC inspe'ctors reviewed selected personnel exposure history files to determine that current NRC Form 4 and previous exposure histories were available prior to exceeding the 1250 mrem quarterly exposure limi The NRC inspectors determined that individuals were not always dating the NRC Form 4 and that when previous radiation exposures were entered on the form the decimal point used to denote rem was not always in place. The licensee stated they had placed additional emphasis on these areas of the for The NRC inspectors reviewed selected records of work functions performed by the licensee and contractors that required other than routine radiation exposure monitoring, such as multibadging or extremity badging with TLD ! The licensee program for recording other than routine exposures appeared to be adequat No violations or deviations were identifie . Internal Exposure Control The NRC inspectors reviewed the licensee's internal exposure control program to determine compliance with the requirements of 10 CFR 20.103, and the recommendations of Regulatory Guide (RG) 8.15, and NUREG-004 The NRC inspectors inspected the reactor auxiliary and containment buildings on several occasions during the inspection to observe internal exposure control practices. Procedures and associated records were also reviewed and discussions were held with licensee and contractor employees to determine if internal exposures during the outage were being controlle The NRC inspectors reviewed a representative sample of the active and inactive RWPs posted for the outage and records associated with their implementation. This review verified that the permit process had been effective during the outage at disseminating the proper internal exposure control methods to be implemented by individuals for each task. The NRC inspectors observed the acquisition of area grab air samples and reviewed nonroutine breathing zone sample results used to track maximum permissible concentration-hours (MPC-hr) personnel exposures.

| The NRC inspectors observed during a facility inspection on November 6, 1985, that a particulate, iodine, noble gas (PING) monitor in room 69 of the auxiliary building was alarming at the high level for the iodine channel. The sarae afternoon, one of the containment building PINGS was in alert level while the other was in high level alarm for the iodine channe Action taken by the licensee in response to the alarms was to order special grab fr samples to assess the airborne concentration of iodin The NRC inspectors examined the PING calibration procedures and records of the.f r calibration to ascertain the significance of the iodine alarm In the course of this review it was determined that PING unit 214 located in room 69 of the auxiliary building did not have documentation on file showing the calibration performed on this unit on August 15, 1985. The licensee stated that the necessary calibrations had been performed, but the calibration records could not be located. This was identified as an unresolved item (285/8525-01) pending the licensee's search for this recor The NRC inspectors examined the post alarm grab air samples in addition to j the routine air samples and found that while iodine concentrations had showed an increase during the outage, measured levels had not exceeded 10 percent of MPC in ary of the sample results reviewed. Special whole body counting resul s performed during the outage also provided verification of the absence of a significant iodine problem with the highest body burden showing 50 nanocuries (7.1 percent of ICRP maximum permissible body burden). Air sample results showed other isotopes to be near or below the lower limit of detection (LLD).

| | |
| The NRC_ inspectors reviewed the licensee's use of respiratory protection equipment and verified that all users including outage contractor personnel had completed the licensee's qualification program. The NRC inspectors observed the cleaning of used respirators and reviewed the records of surveys of respirators prior to bagging and reissuance and found this to have been performed in accordance with Procedure RPP- No violations or deviations were identifie . Radioactive and Contaminated Materials Control The NRC inspectors observed the efforts being implemented during the outage to control contamination and radwaste in the RC The NRC inspectors observed instances of poor radiation safety practices among a few of the auxiliary building decontamination teams in the packaging of used protective clothing (PC) and improper controls at step off pad control points.

The NRC inspectors discussed with licensee representatives the status and basic design for the shower facilities in the general employee training building. The licensee stated that the effluent is collecy.ed in a 1000 gallon retention tank, fitted with a high level alarm, and has the ability to be discharged to either the sanitary sewer system or an external vesse The NRC inspectors expressed concern that the licensee had not developed procedures to prohibit the discharge of potentially contaminated effluents
| |
| -
| |
| via an unmonitored pathway. The licensee needs to: (1) determine the level the high alarm is activated, (2) provide for positive controls on the valve connecting the retention tank to the sanitary sewer line, and (3) develop a procedure which would address the isolation of the tank, ','

The licensee was in agreement that more control over such activities in the future should be exercised to monitor radiographers entering the site protected are No violations or deviations were identifie . Wide Range Noble Gas Stack Monitor The NRC inspectors reviewed the licensee's progress to resolve open item (285/8226-15) NUREG-0737, Item II.F.1 (Attachment 1), Noble Gas Effluent Monitor. The licensee had completed calibration of the low range channel of the wide range noble gas (WRNG) stack monitor RM-063L. The midrange and high range channels had not been calibrated. The NRC inspectors reviewed the calibration for the low range channel of the WRNG monito The NRC inspectors noted that this calibration procedure i referenced count rate meter and detector model numbers that were not the same as those recorded during performance of the calibration. The NRC inspectors discussed with licensee representatives this inconsistency in equipment data and determined that the recorded data more accurately identified the count rate meter and detector. The licensee agreed that the calibration procedure needed to be revised to include. consistent model number The NRC inspectors discussed with licensee representatives the status of the midrange and high range detector systems and FCS TS section 2.21 requirements. Table 2-10 requires that when less than the minimum number of channels are operable, alternate methods for monitoring be initiated and if the channels are not returned to operating status within 7 days a special report shall be submitted within 14 days to the Commission containing plans and schedules for returning the monitors to operable status. The licensee provided a copy of a letter LIC-84-301 dated September 5, 1984, which stated the monitors were expected to be operable by September 14, 198 The licensee stated that a second letter was written after September 5, 1984, which extended the date of expected operability for the mon! tor However, the licensee was not able to locate a copy of the second lette The NRC inspectors stated this is considered an unresolved item

| ~
| |
| The NRC inspectors reviewed the licensee's ALARA program to determine compliance with the requirement bf 10 CFR Part 20.1 and the recommendations of Regulatory Guides 8.8 and 8.1 ,
| |
| l The NRC inspectors determined that the licensee had established a goal of i
| |
| 491 manrem for the year 1985 and had expended 224 manrem as of November 6,
| |
| ~198 The licensee projected that less than 400 manrem would be expended for the year. The licensee stated that the lower ~ exposure was due to less steam generator work and decontamination efforts prior to working in the RC No violations or deviations were identifie . Surveys
| |
| .The NRC inspectors reviewed the licensee's program for implementing and performing radiation, contamination,- and airborne radioactivity surveys to determine ccmpliance with the requirements of 10 CFR Parts 20.103, 20.201, and 20.40 '
| |
| i The licensee's survey program appeared to be adequate for contamination and radiation surveys for prework evaluations and RWP generation. The NRC inspectors noted the licensee routinely collected an airborne radioactivity sample for particulate and radiotodine analysis from the auxiliary building once each day and from the containment building once each work shift. The NRC inspectors determined that the licensee performed other airborne surveys on an as needed basis when conditions warrante ,
| |
| At various times during the inspection period, the NRC inspectors
| |
| '
| |
| conducted independent surveys of the containment and auxiliary buildings to verify that radiological. conditions were as recorded on radiation
| |
| , survey logs and depicted on station area maps. The NRC inspectors also observed housekeeping and temporary radioactive waste storage areas. All areas observed appeared to be acceptabl No violations or deviations were identifie . Notifications and Reports The NRC inspectors-reviewed selected reports to determine compliance with 10 CFR Parts 19.13, 20.407, 20.405, and 20.409.
