SUBJECT:
ROUTINE RADIATION PROTECTION INSPECTION: NRC INSPECTION
REPORT 50-346/98007(DRS) ' AND NOTICE OF VIOLATION
Dear Mr. Wood:
On April 30,1998, the NRC completed a routine inspection of your radiation protection -
. program. The enclosed report presents the results of this inspection.
The inspection was an examination of activities conducted under your license as they relate to
,
radiation safety and to compliance with the Commission's rules and regulations and with the
conditions of your license. The inspection consisted of a selective examination of procedures
and representative records, observations, and Interviews with personnel. Specifically, the
inspection included a review of the as-low-as-is-reasonably-achievabie (ALARA) planning and
controls for the eleventh refueling outage (RFO11), radiation worker performance and the
j
. maintenance of area radiation monitors.-
) Several recent events occurring at your facility were also reviewed, including: radiation
protection personnel response following resin breakthrough from a purification demineralized;
an unescorted operator entry into a Locked High Radiation Area; unanticipated dose rates in
the annulus during incore detector movement; and several personnel contamination events
. following the removal of steam generator insulation.
Overall, the ALARA planning and controls for RFO11 were good, although some ALARA
planning documentation problems were identified. Radiation worker performance, including job
j
coverage by RP personnel was also good, with some examples of poor control of contaminated
l
areas and potentially contaminated material. The radiation protection staff effectively evaluated
the changed radiological conditions following the resin breakthrough, and controlled access into
affected areas without incident.
,
_
One violation of NRC requirements was identified regarding two examples where your staff
failed to evaluate the potential radiological hazards and institute appropriate controls prior to
i
performing work. These examples involved the faiiure to: (1) recognize the potential for
transient, high dose rates in the annulus during incore detector movement given known industry
history; and (2) implement the ALARA controls for steam generator work that were specified in
the radiation work permit and discussed in the prejob briefing. Although the potential for a
substantial personal exposure from these events was unlikely, the identified weaknesses placed
workers at increased radiological risk.
