166.2 d/cm3.sec of Kr and Xe from leaking channel
(1)Assuming same value of v applies to all isotopes of an element.
(2)For 700 Mw and 1 fuel capsule 2.1 x 1019 y/5.6 x 104 = 3.74 x 1014 y.
(3)Number per sec leaking into system vN0 - XN
(4)Number per cm3 ensuing from leaking channel where F is flow rate of He through channel, 2.2 x 105 cm3/sec.
(5)d/cm3.sec of Kr and Xe from leaking channel.
(6)Equilibrium system contamination from leak where V is the system volume, 6.3 x 104 ft3.
(7)Calculated from equilibrium activity by dividing by system volume.
(8)Calculated activity leaving channel the first time.N
