Licensee Action on Previous Inspection Findings No previous inspection findings were outstanding.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Management Controls a.
Management and administrative controls defined in Section 5.0 of Appendix B, Environmental Technical Specifications (ETS) for Units 1, 2 and 3 were reviewed by the inspector with respect to the following items:
(1)
organizational and management responsibility for imple-
<
mentation of the radiological environmental nonitoring program required by ETS-4.2; (2) periodic audit of the environmental monitoring pro-gram; (3) radiological environmental procedures. These items are discussed below.
b.
Appendix B. Technical Specifications 5.1.2 and 5.2.2 assign management and organizational responsibility for implementation of the offsite radiological monitoring program.
The inspector i
'
'
.
.
2 conducted a comprehensive review, including discussions with cognizant licensee representatives, of specific management responsibility for assuring implementation of the monitoring program. Management of the offsite radiological environmental monitoring program is the direct responsibility of the Chief, Radiological Hygiene Branch.
Implementation of the offsite monitoring program is the responsibility of the Office of Natural Resources and the Office of Health and Safety. The subject organizations are charged with provision of technical guidance, assistance, monitoring and other related services as required to assure compliance with the monitoring program defined in Appendix B ETS-4.2.
Inspection disclosed that program management was consistent with requirements defined in the above-referenced specifications. There were no questions regarding this item.
c.
Appendix B, Technical Specification 5.3.1 requires that a periodic audit of the environmental monitoring program shall be conducted, at least, once per calendar year. The inspector reviewed environmental program audits conducted during calendar years 1980 and 1981 (Audit Reports RHB/QA-80-1 and RHB/QA-81-5).
Inspection included the following:
(1) discussions of each audit and its respective findings and recommendations with cognizant licensee representatives; (2) review of licensee organizations' response to audit findings; (3) verification of adequacy of corrective actions implemented.
Inspection disclosed that required follow-up and completion of corrective actions for identified audit findings were implemented. There were no questions regarding this item.
d.
Appendix B, Technical Specification 5.5.2 requires that detailed written procedures for the offsite radiological environmental monitoring program shall be prepared, adhered to, and receive administrative approval.
Inspection disclosed that an approved environmental monitoring procedures manual (Revision 2, 6/9/81)
was prepared and used to assure that all monitoring requirements defined in ETS-4.2 were implemented as scheduled.
Inspection further disclosed the following:
(1) establishment and imple-mentation of a quality control program and procedures therefor, for collection of environmental samples (air, water, milk and vegetation) used in the interlaboratory comparison program.
(2) an internal quality control program for the environmental program and all procedures therefor, whereby approximately one tenth of all samples are analyzed in duplicate.
The revised Environmental Radiological Monitoring Manual (Rev. 2, 6/9/81)
addresses the procedures listed below.

QA Procedure ENVR-3 - Sampling Environmental Media 7.
QA Procedure EVNR-4 - Identification of Ancmalous Measure-ments Inspection disclosed that all procedures appeared to be consistent with technical specification requirements.
The inspector had no questions regarding this item.
6.
Implementation of Radiological Environmental Monitoring Program a.
Appendix B, ETS-4.2 defines all requirements for the radiological environmental monitoring program including specific surveillance and sampling schedules.
Inspection included the following:
(1) a detailed review of the Annual Radiological Environmental Operation Report for the period ending December 31, 1980, as required by Appendix B, ETS-5.6.2.b.1; (2) review of the Alabama Department of Public Health Administration Laboratory Comparative (State / Licensee) analyses of air, water, milk and vegetation split / duplicate samples collected offsite during October, November and December,1980; (3) review of field monitoring records documenting sample collection during the period January 1, 1981 through December 31, 1981.
Inspection disclosed the findings listed below.
1.
Review of the Annual Radiological Environmental Monitoring Report indicated no evidence of increased radioactivity concentrations (detectable by required monitoring) traceable to facility opera-tion.
2.
Review and comparison of the Alabama Department of Public Health Laboratory analytical results for State / licensee sample splits (air, water, milk, vegetation) with analytical data compiled by licensee on the subject samples indicated close agreement.
No significant differences in concentration and/or observed radio-
,
nuclides were disclosed.
3.
Review of field records documenting implementation of required monitoring and sample collections defined in ETS-4.2 disclosed that all such requirements were met during the above-cited period, b.
Inspection of selected monitoring and sampling stations was conducted.
The following stations were included:
(1) all air particulate /
groundwater; (3)pt the two control stations as listed in ETS-4.2; (2)
radioiodine exce public service water intakes; (4) eight randomly
..
.
selected licensee TLD stations exclusive of those located at air particulate /radioiodine monitoring stations.
Inspection also included review of calibration and maintenance records for air particulate /
radioiodine monitoring systems during the period January 1,1981 through January 27, 1982.
Inspection disclosed that the subject systems were calibrated every six months and calibration date posted on each system.
Inspection also disclosed that all other sampling sta-tions inspected were operational except the public service water sampler at the Champion Paper Company intake bay (Courtland, Alabama).
The automatic sequential sampler water intake manifold was detached from the sampler as a consequence of freezing weather conditions.
ETS-4.2 permits deviations from the required sampling schedule as a consequence of malfunction of automatic sampling equipment; however, the specification stipulates that every effort shall be made to complete corrective action prior to the end of the next sampling period.
In the subject case, samples are collected weekly and com-posited on a monthly basis. QA Procedure ENVR-3 allows supplementing automatic sampling with a grab sample from a plant tap water source.
A licensee representative stated that the automatic sequential water sampler would be restored to service as soon as possible to comply with the primary sampling method. The inspector informed licensee represen-tatives that this item would be carried as an inspector follow-up item and would be reviewed during a subsequent inspection (50-259/82-05-01, 50-260/82-05-01,50-296/82-05-01).
7.
Assessment of Licensee Response to NRC Bulletin 81-03 Inspection included review and assessment of licensee's response to NRC Bulletin 81-03:
Flow Blockage of Cooling Water to Safet By Corbicula Sp. ( Asiatic Clam) And Mytilus Sp. (Mussel)y System Components Asiatic clams
.
were first manifested as a nuisance in plant raw water systems at this facility in 1974, and accounted for loss of condenser efficiency on Units 1 and 2.
As a consequence of this finding the licensee initiated a program to clean the waterboxes and intake conduits annually or whenever necessary.
Inspection further revealed that testing and inspection of the following systems are implemented in accordance with the frequency specified in the NRC Bulletin:
(1) Emergency equipment cooling water (EECW); (2) Raw cooling water system (RCW); (3) high pressure fire protection system (HPFP);
residual heat removal service water system (RHRSW). The inspector had no questions regarding this item.
