Dear Sir:

Pursuant to Section 50.59 of the Commission's Rules and Regulations, Yankee Atomic Electric Company (YAEC) hereby proposes the following amendment to Appendix A of the facility license.

y United States Nuclear Regulatory Commission October 15, 1985 Attention: Office of Nuclear Reactor Regulation Page 2 Proposed Change Reference is made to the Yankee Plant Operating License No. DpR-3. This proposed change is in response to Reference (i), and provides p' oo*' '

Technical Specification changes as required for NUREG ' "'* ~ ^ ' ' _ F. h Containment Pressure Monitor, Item II.F.1.5, Containmet M e Mni p b 2r Item II.F.2 Instrumentation for Detection of Inadequate A(p pet'6 'MC),

Item II.F.1-3 and Containment High-Range Radiation Ned;u f, 7ser 12.> J2 . ,

Containment Hydrogen Monitor will be addressed f" 925t%$ capittnswdsse.".

Revised Technical Specification pages are attat ri, Reason and Basis for Change

1. Containment Pressure Monitor (II.F.1.s:

l 1^

The proposed Technical Specification is attached. We believe this 4 change conforms to the staff guidance in Enclosure 1 of Reference (i).

{ 2. Containment Water Level Monitor (II.F.1.5)

The proposed Technical Specification is attached. We believe this a change conforms to the staff guidance in Enclosure 1 of Reference (1). The proposed Technical Specification covers only the Containment Water Level Monitor (wide-range). NUREG-0737, (II.F.1.5) Clarification No. 3 states, " Narrow-range water level monitors are required for all sizes of sumps but are not required in those plants that do not contain sumps inside the containment."

4 The Yankee Plant has a vapor container drain tank which is mounted external to the vapor container. The tank capacity is 480 gallons.

Based on Clarification No. 3 of II.F.1.5, the two existing instrument channels are not required, and therefore we take exception to adding these channels to the Technical Specifications.

3. Instrumentation for Detection of Inadequate Core Cooling (II.F.2)

The subcooling margin monitor was incorporated into the Technical Specifications via Amendment 65 [ Reference (b)).

YAEC's response [ Reference (d)] to Reference (c) requested relief from the requirement to install a Reactor Vessel Level System (RVLS) and also provided a basis for the number and status of core exit thermocouples (CET) and the installation of two reactor vessel upper head thermocouple (UHT). This request for exemption was granted by References (e) and (h).

The proposed Technical Specification for the UNT is attached. We

-believe this change conforms to the staff guidance in Enclosure 1 of Reference (i) for the Reactor Coolant Inventory Tracking System.

l

) United States Nuclear Regulatory Comission October 15, 1985 Attention: Off'ce of Nuclear Reactor Regulation page 3 i

The proposed Technical Specification for the CETs is attached. YAEC

' has described and justified [ References (d, f and g)] the distribution and use of the CETs with respect to the requirement of l NUREG-0737 for ICC Instrumentation System use. To summarize, YAEC will use 8 qualified CET channels for ICC, 4 additional CET channels will be qualified and 2 UHT channels will be qualified for a total of 14 qualified channels. With only 76 fuel assemblies in the total core, the proposed minimum channels operable limit of 1 CET in each of 3 core quadrants provides at least an equivalent thermocouple I coverage per fuel assembly as in the larger plants.

l l

4. Containment High Range Radiation Monitor (II.F.1.3)

The proposed Technical Specification is attached. We believe this change conforms to the staff guidance in Enclosure 1 of Reference (1).

5. Containment Hydrogen Monitor (II.F.1-6) l l This item will be addressed in separate correspondence to be

! submitted in October 1985.

Safety Consideration This proposed change requires an approval that involves both administrative issues and issues involving a safety issue, and is deemed not to involve a significant hazards consideration.

The significant hazards consideration is based on the guidance provided by example in 48FR14870. The changos described in the attachment are classified according to the following examples of actions involving no significant hazards:

1. Actions involving a change that constitutes an additional limitation, restriction or control not presently included in the Technical Specifications or clarifies an existing requirement: for example, a more stringent surveillance requirement or a surveillance requirement not significantly different than previousl/ reviewed and approved, or a change to clarify the intent and avoid misinterpretation of the surveillance requirement and does not reduce or change the intended surveillance.

2. Actions involving a change to make a license conform to changes in the regulations or staff position.

Therefore, based on the above, the changes presented in the attachment are either additional limitations or changes made to conform to NRC regulations and, therefore, do not involve a significant hazards consideration.

l

United States Nuclear Regulatory Commission October 15, 1985 Attention: Office of Nuclear Reactor Regulation Page 4 4 Based on the considerations contained herein, it is concluded that there is reasonable assurance that operation of the Yankee Plant consistent with the proposed Technical Specifications will not endanger the health and safety of the public. This proposed change has been reviewed by the Nuclear Safety Audit and Review Committee.

Fee Determination A payment of $150 is enclosed in accordance with 10CFR170.21.

Schedule of Change The changes described above will be incorporated into the Yankee Technical Specifications upon receipt of your approval.

We trust that you will find this submittal satisfactory; however, should you desire additional information, please contact us.

Very truly yours, Yank e Atomic Electric Company L. H. Heider Vice President / Manager of Operations LHH/.mc Attachment COMMONWEALTH OF MASSACHUSETTS) l )ss MIDDLESEX COUNTY )

, Then personally appeared before me, L. H. Heider, who, being duly sworn, did state that he is a Vice President / Manager of Operations of Yankee Atomic Electric Company, that he is duly authorized to execute and file the foregoing request in the name and on the behalf of Yankee Atomic Electric Company and that the statements therein are true to the best of his knowledge and belief.
