DPR-32 DPR-37 NPF-4 NPF-7 SURRY AND NORTH Ai.'i!NA POWER STATIONS CONTROL ROD REACTIVITY WORTH DETERMINATION BY THE ROD SWAP TECHNIQUE Your letter to us, dated November 7, 1980, on this subject declared that you have found that our use of the rod swap technique is an acceptable method for verifying shutdown margin for Surry Units 1 and 2 and North Anna Units 1 and 2 provided the following conditions are met:
- 1.
Vepco submits the data to NRC within 45 days of the first use of the rod swap after this approval for each unit, and
- 2.
The On-Site Safety Review Committee compares the Vepco prediction for total rod worth and shutdown margin with the prediction by the organization performing the safety analysis and that the effect of any difference is evalu-ated.
This comparison and evaluation is to be done for each cycle prior to initial criticality.
We will meet these conditions.
Your letter also requested that we issue a revised version of our topical report, VEP-FRD-36, (to be designated VEP-FRD-36A) which would incorporate the information that was submitted to you in our letter dated June 26, 1980 (Serial No. 569).
Additionally, your staff eval-
-\\
uation letter to us was to be included in the revision.
This has been (l...p'Y' done.
Enclosed for your use are 10 copies of the revision.
