General
.
This inspection was conducted to examine the preoperational status of the licensee's radiation protection and radwaste programs.
Areas examined included:
the radioactive liquid, gaseous, and solid waste systems; process and effluent monitors; operating, calibration, and preoperational test procedures; certain venti-lation systems; and radiation protection organization, training,
~
procedures, and equipment. No discrepancies from regulatory requirements were identified during the inspection.
3.
Radiation Protection Organization The licensee's Chemistry and Health Physics Department organization was unchanged from the previous radiation protection inspection, except for the addition of three chenistry and radiation testor positions. One position remained to be filled.
Current plans call for coverage of all shifts by chemistry and radiation protection testors.
,
4.
Training According to licensee personnel, the radiation protection orienta-tion training (GOT-1) required for unescorted access to non-REP (Radiation Exposure Permit) plant areas has been completed for those individuals currently requiring such access.
Selective review of the licensee's GOT-1 training records did not reveal any discrepancies.
The inspector attended a COT-1 presentatien.
The instructional requiremenr.r Lf 10 CFR 19.12 were adequately covered.
The presentation had been mootfied since the previous radiation

protegion inspection to correc' the discrepancies noted at that time.-
According to licensee personnel, those individuals who had completed G3T-1 before the presentation was modified have been given the additional training during subsequent radiation pro-tection training sessions.
Additional radiation protection training (GOT-2) 1.a given to those individuals who require unescorted access to areas controlled by REP's.
According to licensee personnel, GOT-2 training is approxi-mately 95% complete. Selective review of the licensee's GOT-2 training records did not reveal any discrepancies.
Operators, station service personnel, and chemistry and radiation testors receive additional radiation protection training. With the exception of the station service personnel, this training is essenti-ally complete.
<
The licensee has not finalized the radiation protection retraining
-
requirements. Licensee procedure AD1828.03 currently specifies conduct of annual COT-1 and'GOT-2 retraining.
Licensee personnel stated that the extent of the retraining effort was currently being evaluated and may be changed.
5.
Procedures g
With a few exceptions, the radiation related procedures have been completed and are ready for implementation.
The most notable procedures which have not been completed are AD1850.02 (Solid Radioactive Waste Processing and Handling) and AD1850.03 (Radio-active Gaseous Release). Additionally, AD1850.01 (Radioactive Liquid Release) requires revision in order to conform to the proposed technical specification requirements and HP1650.02 (Respira-tory Equipment) requires revision in order to conform to the require-ments of 10 CFR 20.103 and Regulatory Guide 8.15.
Selected procedures were reviewed with licensee personnel. Except as noted in this report, no significant discrepancies were identified.
6.
Facilities and Equipment Co'nstruction of radiation protection related facilities (e.g.
radiochemistry laboratory, counting room, access control and
change area, decontamination areas, etc.) and acquisition of radiation protection related instruments and equipment are essentially complete.
Implementation of preoperational acceptance test pro-cedures TP360.02 (Personnel Monitor and Survey Instrumen't Pre-Op)

(
l and TP360.03 (Laboratory Equipment Pre-Op) is about 95% complete
'
according to licensee personnel.
These tests are scheduled for completion before fuel loading.
All but eight area radiation monitors were calibrated.
All area radiation monitors are scheduled for calibration before fuel load-ing. Selective review of the calibration results did not reveal any discrepancies. Corrective actions required as a result of erroneous vendor supplied calibrator information were reviewed.2/3/
--
7.
Respiratorv Protection The licensee was revising the respiratory protection procedure (HP1605.02) in order to conform to the requirements of 10 CFR 20.103 (revised November 29, 1976).
Essentially all of the respira-tory protection equipment was onsite. However, protection factors
_
are not authorized to be used until the respiratory protection program conforms to the requirements of 10 CFR 20.103 and Regulatory
-
Guide 8.15.
The required changes to the program are scheduled for completion before initial criticality.
The licensee's respiratory protection program will be examined further during a subsequent inspection.
8.
Gaseous Radwaste (/
j Although construction and turnover of the gaseous waste system were (
complete, the preoperational test (TP232.01) had not com=enced.
,
Acceptability of the test results requires completion of process monitor calibrations and in-place testing of the HEPA and charcoal filters. The preoperational test is scheduled for completion before fuel loading.
Other than turbine building ventilation exhaust, no unmonitored, potentially contaminated gaseous effluenc paths were identified.
No discrepancies from the FSAR description of the gaseous radwaste system were identified.
According to licensee personnel, quantification of gaseous radio-activity releases will be perfor=ed on a batch basis for waste gas decay tank and containment purge releases and by integration of vent stack monitor output for other releases.
Particulate and iodine releases will be quantified by fixed particulate and charcoal filters. The procedures for control and release of gaseous vastes (AD1850.03) had not been completed by the licensee.
This procedure vill be reviewed during a subsequent inspection.

The licensee has not resolved the problems identified during an earlier inspection related to orientreion of the charcoal filter assembly and the effect on the isokinetiegjof the sampling system caused by the flow splitter modification.- Furtner, it is not clear that the present sampling system is amenable to collection of all required vent stack samples (e.g. tritium and gaseous gamma isotopic).
The efficacy of the sampling system will be checked by the licenses with an airborne DOP mixture.
These data will be reviewed during a subsequent inspection.
9.
Liquid Radvaste Construction and turnover of the clean and miscellaneous liquid radwaste systems were complete.
The clean radwaste preoperational test (TP230) had been started (about 25% complete); the miscel-laneous radwaste preoperational test (TP231) had not been started.
,
Acceptability of the test results require completion of process monitor calibrations. The preoperational tests are scheduled for
'
completion, with a few equipment exceptions, before fuel loading.
No unmonitored, potentially contaminated liquid effluent paths were identified.
All liquid effluents pass through either the storm sewer monitor (RE8442) or the collection box monitor (RE8432).
No discrepancies from the FSAR desc,riptions of the liquid radwaste systems were identified.
The licensee's procedure for control and release of liquid wastes
_,
(AD1850.01) was reviewed.
Several discrepancies from the proposed technical specifications were noted in the procedure.
Liquid radioactivity releases will be quantified on a batch basis.
10.
Solid Redwaste Construction of the Jolid radwaste system is essentially complete.
The system has not been turned over, nor has the preoperational acceptance test (TP233) commenced.
The preoperational test is scheduled for completion before initial power operation.
No discrep-ancies from the FSAR description of the solid radwaste system were identified.
The licensee's procedure for control and processing of solid wastes (AD1850.02) had not been completed.
This procedure
,
will be reviewed during a subsequent inspection.

complete. The preoperational acceptance tests (TP110, TP160,
\\s TF161, and TP170) had been started and were in varying states of completion. Acceptability of the test results requires ~ completion of process monitor calibrations and in-place testing of HEPA and charcoal filters.
The preoperational tests are scheduled for completion, with certain specified exceptions, before fuel loading.5/6/
--
According to licenses personnel, the in-place HEPA and. charcoal filter preoperational acceptance test procedure has been eliminated and the specific system preoperational acceptance test procedures revised to incorporate the filter testing requirements.
Selective review of the ventilation systems preoperational acceptance test procedures identified two procedures (TP160.02 and TP170.01) which did not incorporate the filter testing requirements. Procedure TF160.02 was revised during the inspection to correct this omission.
'
Results of laboratory testing of the impregnated activated carbon,
-
'
conducted during 1975, were geviewed.
The tests, conducted under 90% relative humidity and 25 C conditions, yielded methyl iodide removal efficiencies of 92.01-95.31 percent for a two-inch thick-ness and 99.67-99.89 percent for a four-inch thickness.
Additional laboratory testing was in progress.
The results of the most recent tests will be reviewed during a subsequent inspection.
12.
Process Monitors Construction and turnover of process monitors was essentially complete.
The preoperational acceptance test (TP360.01) had been started. Approximately 10% of the monitors had been calibrated.
The}Jgynseewillca11bracespecifiedmonitorsbeforefuelload-ing.-- -- The remainder of the process monitors are due to be cali-brated before initial criticality. Approximately 50% of the process monitors specified for fuel loading had been calibrated.
A selective review of the completed calibrations did not reveal any discrepancies.
,
Questions raised during a previous inspection regarding adequacy of vendor supplied cgpibration data for process monitors have not been totally resolved.-- Linearity and calibration curves were apparently derived by the vendor for specific types of monitors (e.g. detector and ratemeter combination) but not for individual monitors.
The licensee intends to perform fluid calibrations of the effluent monitors following plant startup (upon generation of radioactive wastes).
These calibrations will be reviewed during a subsequent inspection.
