l Summary Technical Report of Analysis of Capsule from Unit No.1 Reactor Vessal Radiation Surveillance Program Submitted for your review is one copy of the report, " Analysis of Capsule P {

from Northern States Power Company Prairie Island Unit 1 Reactor Vessel Radiation Surveillance Program", WCAP-10102, dated May,1982. This report is submitted in accordance with 10CFR50, Appendix H, Section IV.

The report notes the following:

a) The measured fast neutton fluence of 1.25E19 n/cm closely 2 matches the predicted value for the capsule of 1..T 19 n/cm .

b) The limiting material in the core region exhibited a 65'F increase in the 50 ft. :.b. trans measuredfluenceof1.25E19n/cm{tiontemperatureatthe

. This shift is well within the design curve prediction of Regulatory Guide 1.99.

c) The reactor pressure vessel beltline material is not very sensitive to radiation.

d) The projecteg end of life fluence at h thickness is 2.78E19 n/cm .
