Seabrook Station, Units ) On-site Dnergency Planning 1 and 2) ) and Safety Issues AFFIDAVIT OF KENNETH RUBIN ON REACTOR COOLANT ACTIVITY AT 5 PERCENT POWER I, Kenneth Rubin, being duly sworn, depose and state:

1. 'I am employed by Westinghouse Electric Corporation as a Senior Engineer in Plant & Systems Licensing in the Nuclear Technology Systems Division of the Power Systems Business Unit.

2. My professional qualifications are attached hereto and marked "A".

3 The purpose of my affidavit is to present information which supports use of a reduced reactor coolant activity level at 5% power based upon operating data from 35 nuclear power plants with a similiar fuel design.

4. 'Ihe primary parameter in the determination of the radiological consequences of a Steam Generator Tube Rupture is the reactor coolant activity level (I-131).

5. The design basis event, a steam generator tube rupture at 100%

power, presented in the PSAR asstanes that the activity level in the reactor coolant is at the maximum dose equivalent I-131 reactor coolant specific acivity for a pre-accident iodine spike, of 60 h1 G

a uCi/gm permitted by the Technical Specifications. The results show that the doses'are within the 10CFR100 guidelines.

6. At 5% power, the reactor coolant activity levels will be much lower than the maximum permitted by the Technical Specification limit.

7. Actual Cycle 1 plant data for 35 reactor cores with the 17x17 fuel design (101 measurements) normalized to 100% power shows the following equilibrium RCS I-131 activity:

Highest reported reading. . . . . . . . . . . . . . . . . . . . . . . . . . . 0.06495 uCi/gm lowest reported reading . . . . . . . . . . . . . . . . . . . . .' . . . . . . . 0.00006 uCi/gm Average reading.................................... 0.00429 uci/gm

8. 'Ihe high readings are a' result of small fuel defects. For the most part the operating data shows no fuel defects and the corresponding activity levels are less than 0.001 uCi/gm.

9. The reactor coolant activity levels at 5% are obtained by dividing the normalized 100% power values by 20 since reactor coolant system activity is directly proportional to reactor power.

10. The highest activity level at 5% power becomes 0.00325 uC1/gm, the lowest is 0.000003 uCi/gm, and the average is 0.00021 uC1/gm. Since reactor coolant activity is reported to only 5 significant figures, the low level, when rounded to 5 figures, is less than 0.00001 uCi/gm.

I k Kenneth Rubin Py name is Eenneth Rutin. My business address is P.O. Box 355, Pittsburgh, ? pennsylvania 15230. I am e.mpicyed by the k'estinghcuse Electric Corporation as an Engineer in the Plant & Systems Evaluation Licensir.g group of the Nuclear Technology Systens Division.

s I began my career with Westinghouse in 1970 as a Technician.in the Systems Engineering Department where I perfcmed radiological sna'.ysis. I 3 transferred to the Nuclear Safety Departs.ent in 1978 and was promoted to

. Associate Engineer in 1979 and Engineer in 1984 I have ccapleted numerous assigrnents of increasing responsibility in the areu5'of fission product transport and con'.rcl. I am currently responsible for providir.g the technical lead for all cesign basis radiological safety ar.alyses, which includes steam generator tube ruptre and scurce temd. In this capacity, I was responsible for the development of the cu rent Westinghouse steam generator tube rupture radioactivity transport methodology which was approved by the Nuclear Regulatory Cemrissien in v

1987, and I have been regularly involved in the per:tmance of steam w

generater tube rupture analyses for W. westinghouse pressurized water reactors. I was awarded a Division Engineering Achievement Award in 1983 I nave one US patent in the area of centaircent spray system testing. ,
