Proposed Technical Specification Changes for Clarification Gentlemen:

In accordance with the Commission's Rules and Regulations, Maine Yankee proposes several changes to our Technical Specifications. The specific pages affected, a description of the change, and the proposed replacement pages are included in Enclosures 1, 2 and 3 respectively.

Much of this request consists of changes designed to clarify or simplify Other changes the Specifications without altering the actual requirements.

correct misspelling or minor typographical errors in both the Specifications and Bases.

Only two of the changes requested here are of substance and each is in response to specific NRC recommendations for improvement offered to the industry through published guidance.

The first concerns Specification 3.2 on the matter of iodine spikes in the primary coolant. Generic Letter 85-19 describes the conclusion of the NRC that the reporting requirements in both Maine Yankee and current Standard Technical Specifications are unnecessary and overly burdensome and duplicative We, therefore, have of requirements of the Licensee Event Report system.

MMP$E YANKEE AVOMIC POWER COMPANY United States Nuclear Regulatory Commission Page Two Attention: Document Control Desk MN-86-ll These proposed changes have been reviewed and approved by the Plant Operation Review Committee. The Nuclear Safety Audit and Review Committee has also reviewed the submittal.

We have reviewed this proposal as required by 10 CFR 50.92 to determine whether a significant hazards consideration may exist. A summary of our findings is as follows.

Those proposed changes which are for the purpose of improving clarity, are mere restructuring without altering intent or requirements or which correct typographical errors, have been categorically determined not to involve a significant hazards consideration.

The change concerning primary coolant iodine activity is, in part, administrative in nature in that it merely revises reporting requirements.

This portion has also been determined categorically not to involve a significant hazards consideration.

Adoption of the proposed figure and associated upper limit for iodine spikes represents a minor relaxation from current requirements, permitting levels above the present 60 uCi/g below 80% rated power. In assessing the significance, we considered that such levels would not represent steady state concentrations, but rather a brief excursion. Steady state levels would still be limited to 1 uC1/g. Additionally, such values have been found acceptable for Combustion Engineering plants on a generic basis as represented by Standard Technical Specificaticns.

With regard to the diesel generator test specification, far from raising questions about decreased safety or reliability, based upon the latest industry and staff studies, this change should lead to an overall improvement in safety. The language requested here is consistent with the Standard Technical Specifications found acceptable for other CE plants.

From the foregoing we have concluded that the changes proposed would not:

1. Involve a significant increase in the probability or consequences of an accident previously analyzed; or

2. Create the possibility of a new or different kind of accident from any accident previously analyzed; or

3. Involve a significant reduction in a margin of safety.

Hence, no significant hazards consideration exists.
