i NOTICE OF VIOLATION Centerior Service Company Docket No. 50-346 Davis Besse Nuclect Plant License No. NPF-3 During an NRC inspection conducted from April 27 through April 30,1998, a violation of NRC requirements was identified. In accordance with the General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:

10 CFR 20.1501 requires that each licensee make or cause to be made surveys that may be necessary for the licensee to comply with the regulations in Part 20 and that are reasonable under the circumstances to evaluate the extent of radiation levels, concentrations or quantities of radioactive materials, and the potential radiological hazards that could be present.

Pursuant to 10 CFR 20.1003, survey means an evaluation of the radiological conditions and potential hazards incident to the production, use, tr'ansfer, release, disposal, or presence of radioactive material or other sources of radiation.

10 CFR 20.1201(a)(1)(i) requires, with exceptions not applicable here, that the licensee control the occupational dose to individual adults to an annual dose limit of 5 rems total effective dose equivalent.

Contrary to the above, on April 21 and 23,1998, the licensee did not make surveys to assure compliance with the regulations in 10 CFR 20.1201(a)(1)(i). Specifically:

a. On April 21,1998, the licensee did not perform surveys to identify the potential for transient, high dose rates in the annulus area during incore detector movement, prior to ,

allowing workers to enter the area. This area had dose rates between 10-20 rem pei- 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (contact) on portions of the containment wall during movement of the incore j detectors (50-346/98007-01a).

b. On April 23,1998, the licensee failed to evaluate the ALARA controls implemented during removal of steam generator mirror insulation. ' Specifically, the radiation ,

protection technician covering the job, had relaxed the requirements for wearing faceshields and for " wetting" the contaminated surface, as discussed in the prejob briefing or as specified in the Radiation Work Permit, without performing an evaluation of the potential radiological consequences. The high contamination levels (50-500 millirad per hour (smearable)) which existed in the area required that stringent controls .

be maintained to prevent the spread of airbome contamination (50-346/98007-01b). ]

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

Pursuant to the provisions of 10 CFR 2.201, Centerior Service Company is hereby required to l

submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region lil, and a copy to the NRC Resident inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice).
