Each high radiation area in which the intensity of radiation is greater than 100 mrem/hr but less than or equal to 1000 mrem/hr shall be barricaded and conspicuously posted as high radiation area and entrance thereto shall be controlled by requiring issuance of a Special Work Permit (SWP)a. Any individual or group of individuals permitted to enter such areas shall be provided with or accompanied by one or more of the following:

a. A radiation monitoring device which continuously indicates the radiation dose rate in the area.

b. A radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received. Entry into such areas with this monitoring device may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of them.

c ~ An individual qualified in radiation protection procedures who is equipped with a radiation dose rate monitoring device. This individual shall be responsible for providing positive control over the activities within the area and shall perform periodic radiation surveillance at the frequency specified by the facility Health Physicist in the Special Work Permit.

2. Each. high radiation area in which the intensity of radiation is greater than 1,000 mrem/hr shall be subject to the provisions of (1) above; and, in addition, access to the source and/or area shall be secured by lock(s). The key(s) shall be under the administrative control of the shift engineer. In the case of a high radiation area established for a period of 30 days or less, direct surveillance to prevent unauthorized entry may be substituted for permanent access control.

aHealth Physics personnel, or personnel escorted by Health Physics personnel, in accordance with approved emergency procedures, shall be exempt from the SWP issuance requirement during the performance of their assigned radiation protection duties, provided they comply with approved radiation protection procedures for entry into high radiation areas.

ENCLOSURE 2 DESCRIPTION AND JUSTIFICATION BROWNS FERRY NUCLEAR PLANT (BFN)

Descri tion of Chan e This change will correct a minor deficiency in technical specification 6.3.D.l, page 6.0-10, concerning the designation of high radiation areas. It will change the upper limit from "less than 1000 mrem/hr" to "less than or equal to 1000 mrem/hr."

Reason for Chan e The current technical specification 6.3.D.l contains the requirements for high radiation areas in which the intensity of radiation is greater than 100 mrem/hr but less than 1000 mrem/hr. The current technical specification 6.3.D.2 contains the requirements for areas greater than 1000 mrem/hr. This set of limits is deficient in that the possibility of an area with a radiation intensity of exactly 1000 mrem/hr is not covered.

Justification for Chan e Thetechnical specification 6.3.D contains the requirements for radiation control procedures. The proposed change will clarify and complete those requirements by simply including an area of exactly 1000 mrem/hr in technical specification 6.3.D.1. Since this change will alleviate a deficiency and only result in an infinitesimally small change in technical specification requirements, the margin of nuclear safety will not be reduced.

ENCLOSURE 3 DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION BROWNS FERRY NUCLEAR PLANT (BFN)

UNITS 1, 2, AND 3 Descri tion of Amendment Re uest The proposed amendment would change the Browns Ferry Nuclear Plant technical specifications for units 1, 2, and 3, to clarify that areas in which the intensity of radiation is exactly 1000 mrem/hr are covered by high radiation area control procedures. The current technical specification requirements 6.3.D.l and 6.3.D.2 cover high radiation areas "less than 1000 mrem/hr" and "greater than 1000 mrem/hr," respectively. The proposed amendment will change technical specification 6.3.D.l to cover high radiation areas less than or equal to 1000 mrem/hr.

Basis for Pro osed No Si nificant Hazards Consideration Determination l

The Commission has provided standards for determining whether a significant hazards consideration exists as stated in 10 CFR 50.92 (c). A proposed amendment to an operating license for a facility involves no significant hazards consideration if operation of the facility in accordance with a proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety.

Since the proposed amendment will serve only as a clarification of existing requirements and no relaxation of any current requirements will result, there will be no increase in the probability or consequences of an accident. The proposed amendment will not eliminate or modify any protective function nor permit any new operational condition; and, therefore, will not create any new accident possibilities. Since the proposed amendment is administrative in nature and will correct a deficiency in the current technical specification, no reduction in a safety margin will result.

Since the application for amendment involves a proposed change that is encompassed by the criteria for which no significant, hazards consideration exists, TVA has made a proposed determination that the application involves no significant hazards consideration.
