ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED TECHNICAL SPECIFICATION CHANGES INCORPORATING THE NEW 10 CFR PART 20 REQUIREMENTS 470.1 In Technical Specification (TS) Bases Section 3/4.11.1.4, Liquid Holdup Tanks, it is proposed to delete "10 CFR Part 20, Appendix B, Table II, Column 2" and replace it with "10 CFR Part 20.1302(b)(2)(1)."

NUREG-o.;3 and Standard Review Plan 15.7.3 provide guidance in this

, area. The documents specifically discuss that radioactivity must be controlled so that any leaked fluid does not result in concentrations to a water supply in an unrestricted area in excess of the limits of 10 CFR Part 20, Appendix B, Table II, Columa 2. This is the instantaneous concentration given in the table. It is not the annual average of the concentration, as would be allowed if the section of the rule were cited (20.106). The proposed use of 10 CFR 20.1302(b)(2)(i) as a reference in the bases section would incorrectly imply that annual averaging of the effluent concentration is allowed.

Annual averaging is not allowed for this specification.

Because the new values in Appendix B, Table II, Column 2 to 10 CFR 20.1001-20.2401 are, overall, a factor of 10 lower than before, the Nuclear Regulatory Commission staff considers it acceptable for licensees to propose a factor of 10 increase for these values. These values will maintain the same overall level of effluent control that 4 existed under the old 10 CF,1 Part 20. The 10 curie limit remains unchanged.

It is requested that the Bases section be revised to reference a value of 10 times the limits of Appendix B, Table 11, Column 2 to 10 CFR 20.1001-20.2401.

470,2 In " INSERT 3B". of the new Administrative Controls, Section 6.8.3.e, Radioactive Effluent Controls Program, the phrase "which corresponds to a dose rate of 500 mrem / year total effective dose equivalent"-is unnecessary, inconsistent with Standard Technical Specification wordir,g, and provides no additional control in the context of the TS.

On this basis, it should therefore be deleted.

The intent of the TS is to limit radioactive material concentrations released in gaseous effluents to areas beyond the site boundary. The inclusion of wording for purposes other than controlling radioactive gaseous effluents is discouraged. If clarification for other purposes is deemed necessary, it should be placed in the appropriate licensee document, not_in the TS.

( .

2-470.3 In Administrative Controls, Section 6.12, High Radiation Area, your specification needs to be revised to acknowledge that in 10 CFR 20.1601(a), there are three controls listed: (1) a control device, (2) an alarm signal, and (3) entryways that are locked. The proposed TS must be written to include these controls.

470.4 In Administrative Controls, Section 6.12.2, High Radiation Area, the dose rate values need to be revised to specify a range. This is necessary to distinguish the contrcls needed for High Radiation Areas from those for Very High Radiation Areas. The TS must be revised to specify a range of greater than 1000 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> but less than 500 rads (5 grays) in I hour.

170.5 10 CFR 20.1602, Control of Access to Very High Radiation Areas, requires additional measures, over those in 10 CFR 20.1601, be taken to prevent unauthorized or inadvertent access to areas iri which radiation levels could be encountered at 500 rads (5 grays) or more in I hour at 1 meter from a radiation source or any surface through which the radiation penetrates.

A new TS should be proposed that specifies the measures to be taken to control access to very high radiation areas (e.g., a separate plant procedure, approved by the Plant Operations Review Committee, that establishes control requirements for very high radiation areas).
