Subject:
Clarification to Vermont Yankee Proposed Change No. 142 - Logic System Functional Test Intervals
Dear Sir:
By letter dated November 30, 1981 [ Reference (e)), Vermont Yankee submitted the subject proposed change to revise the Technical Specifications for trip system logic functional testing intervals as a result of the expanded testing methodology incorporated during the 1987 refueling outage. Pursuant to a recent discussion with NRC staff associated with the review of the subject amendment request, Vermont Yankee has been requested to clarify a certain section of the enclosure submitted in support of the submittal.
Specifically, NRC staff has requested that the last paragraph on Page 3 in Enclosure A, "Vermont Yankee Surveillance Program Testing Methodology," be clarified.
This paragraph states that:
"Relay contacts may be visually checked on initial and final conditions or may be checked by other means (i.e., relays picked up, annunciators present, or absence of annunciators, etc.)."

' Attention:
Mr. V. L. Rooney Page 2 The concern expressed by the reviewer was that the phrase "by other means" may be interpreted to supersede other explicit testing requirements stated elsewhere in the document.
In order to eliminate this concern, Vermont tYankee-wishes'to clarify that each logic system contact which performs a safety function shall be verified (tested) on an individual basis. Drhe testing performed during the October 1987 refueling outage was performed in this manner. The referenced paragraph addresses the point in the testing procedure which requires the technician to determine the relay position before as well as after conducting the functional test.
This is done to ensure that the relay will be left in the same position as that in which it was found.
We trust that this clarifies the original intent of our submittal.
Should you have any questions or require further information concerning this matter, please contact this office.
Very truly yours, VERMONT YANKEE NUCLEAR POWER CORPORATION R. W. Capstick Licensing Engineer RWC/25.351 Enclosure l
