Gentlemen:
! SUBJECT:
(NRC INSPECTION REPORT NOS. 50-338/87-30 AND 50-339/87-30)
This refers to the Nuclear Regulatory Commission (NRC) inspection conducted by
B. K. Revsin at the North Anna Facility on August 25-27, 1987. The inspection
included a review of events associated with an exposure in excess of regulatory
limits of the skin of a worker's whole body.
The report documenting this
inspection was sent to you by letter dated September 9, 1987. As a result of
this inspection, failures to comply with NRC regulatory requirements were
identified, and accordingly, NRC concerns relative to the inspection findings
were discussed during an Enforcement Conference held on September 24, 1987. A
letter summarizing this Enforcement Conference was sent to you on October 1,1987.
The violations described in the enclosed Notice of Violation involved a failure
to maintain occupational exposures to the skin below regulatory limits, failure
to perform adequate radiological surveys, and failure to adhere to Radiation
Work Permit procedures involving protective clothing. The event that resulted
in these violations involved a contract health physics technician who had been
performing work in Unit I containment on the evening of August 19, 1987.
Upon
exit from the Radiation Control Area, the technician was found to be contaminated.
Subsequent isotopic analysis showed that the contamination consisted of a
single microscopic particle of pure cobalt-60 with a total activity of 1.6 micro-
curies. The dose to the skin from the particle was determined to be 23.6 rem
based upon an estimated 3.25 hour2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> exposure time. When added to previous skin
exposure for the quarter, this localized skin dose increased the total dose to
the skin of the whole body for the third quarter of 1937 to 23.8 rem.
Violation A described in the enclosed Notice of Violation, which involves an
exposure to the skin in excess of regulatory limits, has been categorized as a
Severity Level IV violation.
As indicated in Supplement IV of the NRC Enforce-
ment Policy, overexposure of this type are normally classified as Severity
Level III violations.
However, after careful consideration of the factors
involved in this specific instance, we have classified this violation as a
Severity Level IV since the health implications of this exposure hre very small
due to the small area of skin that was exposed. The remaining violations have
also been categorized as Severity Level IV violations.
