SUBJECT:

TEST PROGRAH CHANGES - LICENSE CONDTTION 2.C. (3}
The licensee requested a change to its initial plant test prograIII by letter dated Harch ll, 1985, from J.
D. Shiffer (PGIIE) to G.
M. Knighton (NRC},
The change is requested for Power Ascension Test No, 5.2, Radiation Surveys and Shielding Effectiveness.
The licensee has requested that radiation surveys at 90% power be deleted from their power ascension prooram on the basis that adequate radiation survey data has been taken at 30K, 50K, and 761 power to confidently predict radiation levels at lOOX power.
Furthermore, additional surveys >iill be made at 100K powe~ to complete the test requirements.
The licensee also points out that repeating the radiation surveys at 90K power would add unnecessarily to the radiation exposure of test personnel.
Therefore, pursuant to License Condition 2. C.(3) of License DPR-80, we hereby approve the deletion of radiation surveys at 90~'power from the Initial Test Program of the Diablo Canyon Power Plant, Unit 1.
The reviewer for this change was Sam NacKay (X28147)/PSRB.
The reviewer is not aware of any "Differing Professional Opinions" relating to this review.

~l acme Regulatory Guide 1.68, Power Ascension Test Vo. B.b.b, recommends radiation surveys only at 60K and 100~ power.
Based on this guidance and the predictability of radiation levels at full power, the staff concludes that
-.. the -deletion of radiation surveys at 90K power is technically-acceptable.
