REOUEST FOR REVIEW OF WCAP-13360
" WESTINGHOUSE DYNAMIC ROD WORTH 9 MEASUREMENT TECHNIOUE"'
POINT BEACH NUCLEAR PLANT. UNITS 1 AND 2
~
Representatives.of Westinghouse Electric and Wisconsin Electric j
Power Company met with'NRR staff. members on April 28, 1992, to
- discuss:the dynamic rod worth measurement technique developed by 4
4
' Westinghouse.
As. agreed upon in that meeting,. Westinghouse j
submitted-this technique-to the-NRC for review and approval in WCAP-513360,E" Westinghouse Dynamic Rod Worth Measurement Technique."
The i
.purposeiof.this letterris to confirm our desire to use this technique'in theLevaluation of rod worths.during this fall's Unit 2 start-upffollowing its' annual refueling-outage and in other subsequent start-ups at Point Deach Nuclear Plant.
y
~
EThe, dynamic rod worth measurement: technique was demonstrated (successfully at' Point Beach in November 1991 during stact-up l
following our. Unit 2 refueling outage. - The: results of this L
dem7nstration~ indicate that'the dynamic rod worth technique measures q
rod worths to..the same degree of accuracy as our. current rod bank
- exchange measurements. =The dynamic rod worth measurement technique
. proved to~be a-simple method for determining the integral rod worth Lof1each-bank without the effects of otner banks in the core.
We =
have found that:thefexclusive use of the dynamic rod worth f
~measurementetechnique will save approximately'eight_ hours of critical' path: time and the water processing costs associated with Lthe rod ~ swap method.
This measurement technique will also allow us g
- toidetermine rod: worth while changing reactivity by only one method.

We request NRC review and acceptance of WCAP-13360 by November 1, 1992, so that we may use this technique to. measure rod worths during start-up following our scheduled fall 1992 Unit 2 refueling outage.
Please contact us if you have any questions.
