SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 213 TO FACILITY OPERATING LICENSE NO. DPR-50 METROPOLITAN EDISON COMPANY JERSEY CENTRAL POWER & LIGHT COMPANY PENNSYLVANIA ELECTRIC COMPANY GPU NUCLEAR. INC.

THREE MILE ISLAND NUCLEAR STATION. UNIT NO.1 DOCKET NO. 50-289 1.0 INW ODUCTION By letter dated June 11,1998, GPU Nuclear, Inc., submitted a Technical Specification Change Request (TSCR) for Three Mile island Nuclear Station Unit 1 (TMI-1). The purpose of this TSCR is to incorporate an alternate High Radiation Area Control, which meets the requirements of 10 CFR 20.1601. The proposed alternate control would prov.de greater operational efficiency by reducing the number of areas within the plant required to be maintained locked to prevent unauthorized or unintended access, in addition, a clarification was added to Technical Specification (TS) 6.12.1.b to plainly state that the personnel access requirements from TS 6.12.1.a are also required in specification 6.12.1.b. Also, an editorial change is made on TS 6.12.1.6 to make the configuration of the term, "30 cm (11.8 in)" consistent with TS 6.12.1.a.

2.0 EVALUATION Section 20.1601, " Control of access to high radiation areas," of 10 CFR Part 20, " Standards for Protection Against Radiation," requires licensees to institute strict control to areas where an individual could receive greater than 100 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (high radiation area). Regulatory Position 2.4 (Part C section 2.4) in Regulatory Guide (RG) 8.38 describes an acceptable alternative to maintaining all high radiation areas.

The licensee has proposed the following changes to TMI-1 TS 6.12.1.b. The proposed changes and their justification are as follows:

2.1 Alternative control scheme for hiah radiation areas.

l Current TS require that each High Radiation area in which the intensity of radiation at 30 cm (11.8 in.) is greater than 100 mrem /hr, but less than or equal to 1000 mrem /hr shall be -

barricaded and conspicuously posted as a High Radiation Area, and personnel desiring i

, entrance shall obtain a Radiation Work Permit (RWP). Any individual or group of individuals entering a high Radiation Area shall (a) use a continuously indicat'ng dose rate monitoring device; (b) use a radiation dose rate integrating device which alarms at a pre-set dose level (entry into such areas with this monitoring device may be made after the dose rate levels in the area have been established and personnel have been made knowledgeable of them); or (c) assure that a radiological control technician provides pos:tive control over activities within the area and periodic surveillance with a dose rate monitoring instrument.

The licensee has proposed to include a flashing-light waming option to the above TS. TS section 6.12.1.b.2 will require for individual high radiation areas where an individual could receive in any 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> a deep dose lit excess of 1000 mrom at 30 cm (11.8 in.) but less than 500 j

rads at 1 meter (3.28 ft.), that are located within the large areas such as a reactor containment,

)

where no enclosure exists for the purposes of locking, and where no enclosure can be reasonably constructed around the individual area, that the individual areas shall be barricaded and conspicuously posted, and a flashing light shall be activated as a warning device.

i The request is acceptable to the staff since it is consistent with 10 CFR 20.1601 and RG 8.38, Part C, Section 2.4.

2.2 Makina minor editorial chanaes for consistency The licensee has proposed minor revisions to improve clarity and consistency. A clarification was added to TS 6.12.1.b to plainly state that the personnel access requirements from TS 6.12.1.a are also re auired in TS 6.12.1.b. Also, an editorial change is made in TS 6.12.1.b to make the configuralon of the term, "30 cm (11.8 in.)" consistent with TS 6.12.1.a.

The staff has reviewed these proposed changes and considers them to be minor or editorial in nature. The changes add clarity to the TS, and the staff finds them to be acceptable.

3.0 STATE CONSULTATION

In accordance w th the Commission's regulaCons, the Pennsylvania State official was notified of the proposed issuance of the amendment. The State official had no comments.

4.0 ENVIRONMENTAL CONSIDERATION

The amendment changes recordkeeping, reporting, or administrative procedures or requirements. Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10). Pursuant to 10 GFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

5.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the healtn and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the
