'of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions." (NUREG-1600) the violations are listed below:

control of radioactivity for limiting materials released to the environment and limiting personnel exposure.

Contrary to the above, on May 30, 1998. the licensee failed to establish 3rocedural guidance for the abnormal vent path used for degassing the Jnit 1 volume control tank to the environment. This resulted in an unplanned release of radioactivity (approximately 0.409 curies) that initiated an auxiliary building radiation gaseous monitor alarm.

This is a Severity Level IV violation (Supplement IV).

B. 10 CFR 50 Appendix B. Criterion VII. Control of Purchased Material.

Equipment and Services, as implemented by the licensee's approved Quality Assurance (0A) Topical Report (Duke-1-A). Amendment 22. Section 17.3.2.4. Procurement Control. requires that measures be established for the procurement of services associated with the station's OA Condition

1.

Additionally, the depth of the I servic.e supplier's performance evaluation was not consistent with the service's importance to safety, complexity, quantity. and frequency of procurement. These deficiencies contributed to the EDG sub-component failures, which occurred on EDGs 1B and 2A on May 31 and June 4. 1998.
