3.8.C/O.S.C Meehan cal Vacuum Pum The purpose of isolating the mechanical vacuum pump lines is to limit the release of activity from the main condenser. During an accident, fission products would be transported from the reactor through the main steam lines to the condenser The fission product radioactivity would be sensed by the main steam line radioactivity monitors which initiate isolation.

O.S.A and Q.S.B BASES The surveillance requirements given under Specification 0 S.A, and Q.S.B provide assurance that liquid. and gaseous wastes are properly controlled and monitored during any release of radioactive materials in the liquid and gaseous efiluents These surveillance requirements provide the data for the licensee and the Commission to evaluate the station's performance relative .to radioactive wastes released to the environment. Reports on the quantities of radioactive materials released in effluents shall he furnished to the Commission on the basis of Section 6 of these technical specifications. On the basis of such reports and any additional information the Commission may obtain from the licensee or others, the commission may from time to time retxuire the 1$ .censee to take such actions as the Commission deems appropri'ate.

3.8.D and 4.8.D BASES The ob)ective of this specification is to assure that leakage from byproduct, source, and special nuclear radioactive material sources does not exceed allowable limits 291

ENCLOSURE 2 DESCRIPTION AND JUSTIFICATION OF CHANGES (TVA BFNP TS 2()6)

1. Units 1 and 2 - page 271 Descri tion The proposed change is to the Bases section which describes the position on the drywell-suppression chamber vacuum breaker valves closing cycle.

Presently the indication is "Closing Cycle - Green - On ( C 30 Open)."

It is proposed to change this to read "Closing Cycle - Green - On

( (80 Open)."

Justification This proposed change is only to correct a typographical error in the units 1 and 2 specifications. This bases section in unit 3 specification reads "Closing Cycle - Green - On ($ 80o Open)." Therefore, this change will make the units 1 and 2 specifications consistent with unit 3.

This proposed change will not affect operations, safety margins, accident analysis, or overall plant safety.

2. Pages 286 and 291 - Units 1 and 2 Pages 307 and 315 Unit 3 Descri tion The proposed amendment is being made to change "pump" to <<pumps" in Section 3.8.C. This section refers to a mechanical vacuum pump when, in fact, there is more than one pump. The section is being changed to clarify that fact. Also, Section 3.8.C/4.8.C bases are being revised to reflect the correct number of pumps.

Justification This proposed change is being made to have the technical specifications be consistent with the plant's configuration. There are two mechanical vacuum pumps in a parallel configuration. Each pump and line can be individually isolated. Both lines are isolated on a main steam line high radiation signal.

P>'~C

'I P

A il' J

3. Pages 338 - Units 1 and 2 Page 368 - Unit 3.

Descri tion The proposed change is the addition to the technical specification Administrative Controls section of a reference to the fact that there are written procedures covering shift overtime limitation at Browns Ferry.

Justification NRC letter from D. B. Vassallo to H. G. Parris dated July 27, 1980, TVA was requested to submit proposed technical specifications regarding limits on shift overtime in accordance with the guidelines of the revised Commission Policy Statement, reference NRC Generic Letter No. 82-12 dated June 15, 1982. This proposed change to the technical-specifications is being made in response to that July 27, 1984 letter. This proposed specification will provide assurance that written procedures on limiting shift overtime shall be prepared, approved, and adhered to.

W ENCLOSURE 3 PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION (TVA BFNP TS 205)

1. Descri tion of Amendment Re uirement The proposed amendment would correct a typing error on vacuum relief valves, page 271 of units 1 and 2. The statement saying "Closing Cycle-Green - On ((30 Open)" should be "Closing Cycle - Green - On (<80 Open)." This change makes the technical specifications consistent with the unit 3 technical specifications.

Basis for Pro osed No Si nificant Hazards Consideration Determination The Commission has provided examples of license changes which are likely to involve no significant hazards consideration (48 FR 14870). One of the examples of actions likely to involve no significant hazards considerations is

"(i) a purely administrative change to the technical specifications. For example, a change to achieve consistency through the technical specifications, correction of an error, or a change in nomenclature." Because this proposed change is only to correct an error in the typing of the technical specifications it is clearly encompassed by example (i).

2. Descri tion of Amendment Re uirement The proposed amendment is being made to change "pump" to "pumps" in Section 3.8.C. This section refers to a mechanical vacuum pump when, in fact, there is more than one pump. The section is being changed to clarify that fact. Also, Section 3.8.C/4.8.C bases are being revised to reflect the corrected number of pumps.

Basis for Pro osed No Si nificant Hazards Consideration Determination The Commission has provided guidance concerning the application of the standards by providing examples of actions that are not likely to involve significant hazards considerations (48 FR 14870). One example of actions not likely to involve significant hazards considerations is a purely administrative change to technical specifictions: for example, a change to achieve'onsistency throughout the technical specifications, correction of an error, or a change in nomenclature.

The proposed amendment is being made to clarify, in SectS. on 3.8.C, that there is more than one mechanical vacuum pump. There are two pumps situated in parallel with an isolation valve at each pump suction. Only one pump is used at a time. The Bases for this section is also being revised to reflect the actual plant configuration. It, therefore, is encompassed by the example.

Since this proposed amendment is encompassed by an example of action not likely to involve significant hazards considerations, TVA proposes to determine that the proposed amendment does not involve a significant hazards consideration.

8 ~,

~ '1 g ~

3. Descri tion of Amendment Re uirement The proposed amendment would modify the technical specification to include a requirement for written procedures to limit overtime of personnel performing safety-related functions.

Basis for Pro osed No Si nificant Hazards Consideration Determination The Commission has pr ovided examples of license changes which are likely to involve no significant hazards consideration (48 FR 14870). One of the examples of actions likely to involve no significant hazards considerations is "a change that constitutes an additional limitation, r estriction, or control not presently included in the TS: for example, a more stringent sur veillance requirement." This change involves the addition of a new requirement to have written procedures for limiting shift overtime similar to the June 15, 1982 NRC Commission Policy Statement. Because this change adds an additional control not presently included in the technical specifications, it is clearly encompassed by the above example of an action not likely to involve a significant hazards consideration.
