During the Nuclear Regulatory Commission (NRC) inspection conductea on January 30 - February 3,1989, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1588), the violation is listed below:
10 CFR 20.201(b) requires each licensee to make or cause to be made such surveys as (1) may be necessary for the licensee to comply with the regulations in 10 CFR Part 20 and (2) are reasonable under the circumstances to evaluate the extent of radiation hazards that may be present.
Technical Specification 6.12.1 requires in lieu of the " control device" or
" alarm signal" required by Paragraph 20.203(c)(2) of 10 CFR 20, each high radiation area in which the intensity of radiation is greater than 100 mrem /hr but less than 1,000 mrem /hr shall be barricaded and conspicuously posted as a high radiation area and entrance thereto shall be controlled by requiring issuance of a Special Radiation Work Permit.
Any individual or group of individuals permitted to enter such aieos shall be provided with or accompanied by one or more of the following:
a.
A radiation monitoring device which continuously integrates the radiation dose rates in the area.
b.
A radiation monitoring device which continuously integrates the dose rate in the areas and alarms when a preset integrated dose is received.
c.
An individual qualified in,adiation protection procedures who is equipped with a radiation dose rate monitoring device.
Contrary to the above, the licensee failed to perform radiation surveys l
necessary to evaluate the extent of radiation hazards present and entered the high radiation areas violating Technical Specification 6.12.1 requirements in that; on February 2,1989, two auxiliary unit operators entered a pipe chase on Unit 2, elevation 690, on a standing general radiation work permit, where radiation levels of 3,500 mrem /hr contact on piping and 750 mrem /hr general area gamma dose rates existed.
The AUO's did not have an integrating dose rate device, or an integrating dose rate device that alarms when a preset integrated dose is received, or an individual qualified in radiation protection, equipped with a dose rate device to provide positive control or perform radiation surveys.
