PHYSICS TEST PROGRAM The. physics test program to be utilized for Cycle 7 start-up is attached.
This is the first revision to the Palisades Plant Physics test program since Cycle 4 submitted Octob~r 31, 1979.
The test program has been revised to bring it into alignment with the newly developed ANS 19.6 and to reflect more recent general industry practices at PWRs.
The procedure retains both the "review" and "acceptance" criterion for each test and maintains the commitments with regard to remedial action in case a criterion is exceeded.
The attached program is provided for your information.

REMEDIAL ACTION A.
REVIEW CRITERIA Failure to meet a test result review criterion is an indication that there may be some deficiency in the test, prediction or core loading.
If a test result falls outside the review criterion, an engineering review will be conducted to determine the reason for the deviation and its impact on reactor safety.
Such a review may consist of, but not be limited to, a review of the test and equipment, a repeat of the measurement, a review of the predictive calculation, a correlation with the results of other tests and/or a review of the results of testing from previous cycles.
B.
ACCEPTANCE CRITERIA Failure to meet an acceptance criterion indicates that a deficiency exists which may result in a violation of technical specification limits.
In such a case, further operation shall beappropriately restricted to maintain margins of safety.
An engineering review as described above shall be conducted to determine the cause.of the
. deviation and appropriate corrective actio~.
In the case of rod worths, the worth of an additional rod bank will be measured.
The Plant Review Committee will review the action taken and disposition of the deviation before commencement of normal operation.
