ENCLOSURE 1 NOTICE OF VIO'd. TION STP Nuclear Operating Company Docket No.: 50-4d South Texas Project Electric Generating Station License No.: NPF 76 During an NRC inspection conducted on January 12-15,1998, three violations of NRC requirements were identified. In accordance with the " General Statemerit of Policy and Procedure for NRC Enforcement Actions," NUREG 1600, the violations are listed below; A. 10 CFR 19.12(a) states, in part, that all individuals who in the course of employment are likely to receive in a year an occupational dose in excess of 100 millirems shall be kept informed of the storage, transfer, or use of radiation and/or radioactive material.

Contrary to the above, radiation workers who were likely to receive an occupational dose in excess of 100 millirems per year were not informed of the presence of airborne radioactivity. Specifically, on September 23 and September 28,1997, workers in the Unit i reactor containment building and Unit i reactor cavity area, respectively, were not informed that they were working in an airborne radioactivity area.

This is a Severity Level IV violation (Supplement IV) (50-498/9802-01).

1 B. Technical Specification 6.11.1 states, in part, that procedures for personnel radiation protecticn shall be prepared consistent with the requirements of 10 CFR Part 20 and shall be approved, maintained, and Edhered to for all operations involving personnel radiation exposure.

10 CFR 20.1501(a) states, in part, that each licensee shall make or cause to be made, surveys that may be necessary for the licensee to comply with the regulations in this part  !

and are reasonable under the circumstances to evaluate concentrations or quantities of radioactive material and the potential radiological hazards that could be present.

Radiation Protection Procedure OPGP03 ZR-0050, ' Radiation Protection Program,'

Revision 1, Section 4.6.4, states, in part, ' Job coverage, or specific surveys, shall be of the type and frequency . . . to assess the extent of . . concentrations of radioactive materials and the potential radiological hazards to which workers may be exposed."

Cor'trary to the above, between 3:40 p.m. on September 22, and 12:15 a.m. on September 23,1997, airborne radiciodine activity surveys were not performed in Unit i reactor containment building to assess the extent of concentrations of radioactive material, and the potential radiological hazards to which workers may have been exposed.

This is a Severity Level IV violation (Supplement IV) '50-498/9802-02).

C. Technical Specification 6.8.1.a states, in psit, that written procedures sh:al be established, implemented, and maintaineri covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

Regulatory Guide 1.33, Appendix A Section 7.e.3, recommends procedures for airborne radioactivity monitoring.

Radiation Protection Procedure OPRPO4 ZR 0015,"Radiologicd Posting and Warning Devices," Revislor. 3, Section 2.2, states. In part, "STP (South Texas Projects) will post airborne radioactivity areas at 0.25 DAC or greater."

Contrary to the above, from 11:07 p.m. until 11:45 p.m. on September 28,1997, the l

- Unit i reactor cavity was not posted as an airborne radioactivity area when airborne radioactivity sample results revealed that the airborne radioactivity was greater than 0.25 DAC.

This is a Severity Level IV violation (Supplement IV) (50-498/9802-04).

l Pursuant to the provisions of 10 CFR 2.201, STP Nuclear Operating Company is hereby i required to sut>mit a written statement or explanation to the U.S. Nuclear Regulatory i Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the
