.4 (8,000 PCi/1) is about one chance in 3 million per reactor year for the Schuylkill and less than one chance in a billion per year for the Delaware (Ref. 3,
- p. 19; see Second PID p. 258).
If the source term revisions discussed in paragraph 15 are considered, the probability that the 90 r thirty day PAG would be S
exceeded in the Schuylkill could be as low as one chance in a hundred million per year (factor of 5) or ~
less than one chance in a billion per year (factor of 10 or more).
It is estimated that the isotopes of iodine might be significant contributors to the dose l
(330 mrea in one month) which constitutes PEMA's PAG.
The calculation of the rate at which iodine, deposited l
t on a watershed, leaches into the river is discussed in 4
paragraph 10.
Using the model described there, there would be a chance of'about one chance in 100,000 per reactor year that the PEMA short-term PAGs for 131I t
(3000 pCi/1) might be exceeded in the Schuylkill River, and about one chance in 150,000 per reactor l
t i
year that they might be exceeded in the Delaware River. These probabilities are the same as the upper l
bound probabilities given in the previous written i
testimony (Ref. 3, p.19) and on page 258 of the i

Second PID even though the calculation given there assumed that the fraction of the deposited iodine that would enter the drinking water source in the short l
term would be 50 times that of the strontium (i.e., close 16 8412070354 841127 PDR ADOCK 05000352 T
