This routine, unannounced inspection of the Radiation Protection (RP)
program included:
training, external exposure control, control of radioactive materials, contamination survey and monitoring, shipping and transportation, and maintaining exposure as low as reasonably achievable (ALARA).
Results:
No deviations or violations were identifie Based on interviews with licensee personnel, review of records, and observation of outage work, the licensee's RP program continues to improv The licensee's ALARA program was, also considered a strengt PDR AO PNUJ

- D. Davidson, Compliance Supervisor
- J. Davis, Superintendent, Technical Services
- D. LeGette, Compliance Engineer
- R. Slocum, Radiation Protection Supervisor
- S. Spear, Radiation Protection General Supervisor
- C. Yongue, Radiation Protection Manager Other licensee employees contacted during this inspection included craftsme Nuclear Regulatory Commission
- W. Poertner, Resident Inspector
- Attended exit interview 2. Occupational Exposure (83750)
The licensee is required by 10 CFR 19.12 to provide radiation protection training to workers. Technical Specification (TS) 6.1.1.4 requires that the staff of the station shall meet the minimum requirements encompassing the training and experience described in Section 4 of ANSI/ANS 3.1-1978,
"Selection and Training of Nuclear Power Plant Personnel."
Regulatory Guides 8.13, 8.27, and 8.29 also outline topics that should be included in trainin The inspector discussed training and qualifications of contractor Health Physics (HP) technicians with licensee personne Prior to being accepted for work at the facility, the 96 contract HP technicians who were hired to support the Unit 2 outage must successfully complete general employee training, a written HP knowledge test, and site specific training which includes a class and test on HP site procedure The inspector reviewed the assignments and qualifications for contract HP technicians and selected training records for seven technicians performing job coverage in containment and the Auxiliary Buildin The inspector reviewed the seven HP contract technician resumes and noted that most did not meet the requirements for ANSI/ANS 3.1-1978 qualifications and some barely met the qualifications for ANSI/ANS N18.1-197 *4 A revised collective dose estimate three weeks into the Unit 2 Refueling/Maintenance outage of 1990 was recently complete Licensee representatives stated that, barring any unscheduled outages, the 1990 collective dose would be closer to 330 person-rem, or 110 person-rem per unit which is significantly below the norm for pressurized water reactor In assessing the licensee's ALARA program, the inspector found the following general elements that contribute to the stations ALARA program:
a All departments at the plant consistently contribute ALARA action items for ALARA coordinator review and ALARA committee approval and implementatio o Tanks and piping with high dose rates are flushed resulting in significantly lower dose rates and dose saving The Condensate Test Tank B was flushed in April reducing dose rates from 40 R/hr to 2 R/h Obsolete piping with high dose rates are being removed. The following examples show commitment to ALAR On April 13, 1990, a 300 foot length of an obsolete resin line in the Unit 1 work area was removed thereby reducing dose rates in the Unit 1 work area (2 mr/hr to 5 mr/hr),
drumming room (10 mr/hr to 3 mr/hr),
and LPI hatch area (50 mr/hr on eastwall of room to background).
The line was 3-300 mR/hr (contact) and an estimated 4 to 5 person-rem per year will be saved by removing this lin The licensee has also approved replacement of the component drain header in the lower containment with smoothbore lines. These lines are the major contributor to exposure in the lower containment work areas, a significant reduction in dose rate o Radiation surveys in high dose rate fields are performed with remote instrumentatio Collective exposure for performing these steam generator surveys remotely was 85 mrem; the collective exposure in performing the surveys physically was estimated to be 400 mre o Where possible inspections are performed remotely. In September, the licensee performed CRDM flange inspections from the the top of the service structure by utilizing video. This eliminated exposure as the removal of the CRDM Fans became unnecessary; reduced area dose rates were achieved due to the fact that stud removal was unnecessary as the fans remained in plac o Outages at Oconee have been averaging approximately 40 day Work scope is still strictly controlled, and planners walk down the majority of job No violations or deviations were identifie. Shipping and Transportation of Low Level Radioactive Wastes (83750)
10 CFR 71.5 requires that licensees who transport licensed material outside the confines of its plant or other places of use, or who deliver licensed material to a carrier for transport to comply with the applicable
- requirements of the regulations appropriate to the mode of transport of the Department of Transportation in 49 CFR Parts 170 through 18 The inspector reviewed the shipping records for Radioactive Shipments90-001, 90-004,90-010, 90-024, and 90-030. The examined shipping manifest was prepared in accordance with 49 CFR Part 170-189 and 10 CFR 20.311 requirement All radiation and contamination survey results were within the limits specified for the mode of transport and shipment classificatio No violations or deviations were identifie.

(Closed)
NCV 50-269, 270, 287/90-14-01:
Failure to have quarterly ALARA committee meetings as required by procedur The inspector reviewed licensee documentation that substantiated resumption of ALARA committee meetings on a quarterly basi This item is considered close. Exit Interview The inspector met with licensee representatives, denoted in Paragraph 1 on September 27, 199 The inspector summarized the scope and findings of the inspectio The licensee did not identify any documents received by the inspector during the inspection as proprietar Licensee management was informed that the one NCV discussed in Paragraph 7 was considered closed.
