l

a. Reactor coolant shall be limited to:

1. 1 0.2 pCi/ gram DOSE EQUIVALENT I-131,

2. 1 100/E VCi/ gram, and

3. 1 5.0 x 10-6 pCi/ gram gross alpha activity.

b. Off-gas emission, measured at the 150 cu. ft. off-gas holdup tank effluent monitor, shall be limited to j[ 750 Ci/d (P/Pp) +

l AT (1-0.018t)(P/Pp), where:

i

1. (P/Pp) = fraction of RATED THERMAL POWER between 33 MWt and 165 i MWt, l

2. AT = tramp activity, Ci/d, not to exceed 1500, at THERMAL POWER l (Pg) as determined upon initial power escalation after each l refueling.

i

3. t = days after the determination of AT with the limitation that t < 50.

4. Activity values shall be normalized for correlation with previous cycles due to changes in monitoring, sampling and/or analysis methods.
