Subject: Potential Part 21 on irradiations performed with the cobalt-60 sources in the Georgia Tech hot cell
Reference: Georgia Tech letter dated 3/15/2002, received by Wyle 4/11/2002
Pursuant to the 10 CFR Part 21 requirements, this letter notifies the NRC of a Potential Part 21 condition.
An error in irradiation dose units is identified in the attached letter from Georgia Tech letter dated March 15, 2002, which was received by Wyle on April 11, 2002. The error applies to all equipment irradiated with the cobalt-60 sources in the Georgia Tech hot cell from 7/24/1997 to 7/6/2001. Georgia Tech reported radiation doses in units of rads-air (absorbed dose in air) instead of Roentgens. Since one Roentgen is equal to 0.877 rad, the actual dose is less than the reported value.
Wyle will perform an evaluation to determine:
1. Wyle projects that include irradiation with the cobalt-60 sources in the Georgia Tech hot cell from 7/24/1997 to 7/6/2001.
2. The actual dose absorbed by equipment in said projects.
3. Whether the actual dose in said projects envelops the customer-specified requirements.
Wyle Laboratories has the capability and chooses to perform the evaluation to determine if a defect exists. It is the responsibility to Wyle Laboratories to inform the purchaser(s), and any affected licensees.
Wyle will complete the specified evaluation of the circumstances within sixty (60) days of discovery of the potential defect. The NRC will be provided a copy of Wyle' 5 evaluation report.
