UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 150TO FACILITY OPERATING LICENSE NO.
DPR"58 AND AMENDMENT N0.136 TO FACILITY OPERATING LICENSE NO.
DPR-74 INDIANA MICHIGAN POWER COMPANY DONALD C.
COOK NUCLEAR PLANT UNITS NOS.
1 AND 2 DOCKETS NOS.
50-315 AND 50-316
- 1. 0 INTRODUCTION By letter dated June 25, 1990, as amended August 14, 1990, the Indiana Michigan Power Company, requested an amendment to the Technical Specification
- 6. 12.2 for the Donald C.
Cook Nuclear Plant, Unit Nos.
1 and 2 to provide an alternative method of control of access to high radiation areas in which the dose rate is greater than 1,000 mrem/hr.
- 2. 0 EVALUATION Technical Specification (TS) 6.12.2 for Donald C.
Cook Nuclear Plant, Unit Nos.
1 and 2 currently requires that locked doors be provided to prevent unauthorized entry into high radiation areas in which the dose rate is greater than 1,000 mrem/hr.,
These doors are to remain locked except during periods of access by personnel under an approved radiation work permit which shall specify the dose rate levels in the immediate work areas.
Because there are some areas where it is not practicable to provide a locked door, the licensee is requesting approval of an alternative method ot controlling access to the high radiation area.
That alternative method is to substitute
- posted, roped-off areas and flashing lights for locked doors in situations in which it is not possible or practicable to provide locked doors because of area size or configuration.
The licensee in proposing the TS changes has followed staff guidance contained in NRC Information Notice 88-79, "Misuse of Flashing Lights for High Radiation Area Controls."
They have also committed to only apply this flexibilityfor areas where a locked door is not a viable solution for controlling access to high radiation areas.
The staff has evaluated the licensee's proposed alternative and has determined that this requested alternative is consistent with the provisions of 10 CFR 20.203(c)(5) and of the current standard technical specifications; therefore, the proposed change is acceptable.

3.0 EHYIRGNhiEtlTAL COt/SIDERATION These amendments involve a change in the installaticn or use of a facility component located within the restricted area as defined in 10 CFR Part 20.
Me have determined that the amendments involve, rc significant increase in the
- amounts, and no significant charge in the types, of any effluerits that may be released cffsite, and that there is no sigriificant increase in individual cr cumulative occupational 1'adlation exposure.
The Commission has previously issued a proposed findirig that these amendments involve no significant hazards consideration arid there has been rio public comment ori such finding.
Accordingly, these amendments me<<t the eligibility criteria for cateoorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b),
no environmental impact statelTient or environmental, assessment need be prepared iri connection with the issuarce cf these amendment.
- 4. 0 COKCLL'SION We have concluded, based cn the considerations discussed above, that (I) there is reasor:able assurance that the health and safety of the public will not be erdargered by operas.ior ir the proposed
- manner, arid (2) such activities will be corducted iri ccmpliarce with the Core:ission's regulaticris, and
%he issuance of t.he amerdoents will net be iriimical to the collKcn defenise ard security or to the health and safety of the public.
