The maximum permissible flow rate will be set on the same basis but including the engineering safety factor of 0.5. The RM-A10 setpoint level S isdefined as:
o 5, 5 1.5c (5) where:
c
= count rate of the waste gas decay system monitor corresponding to the measured concentration (uci/ml).

The maximum permissible waste gas flowrate f,(cc/sec) is calculated from the maximum permissible dose rates at the site boundary according to:
f,5 the lesser of f, or f, (6) where:
f,
= the maximum permissible discharge rate based on total body dose rate.
= 0.25 x Da + [X/Q x 1.5 X,, K,]
(7) f,
= the maximum permissible discharge rate based on skin dose rate.
~
= 0.25 x D33 + [X/O x 1.5 E X,,(L, + 1.1M,)]
(8)
X,, = the concentration of noble gas radionuclide iin the waste gas decay tank whose contents are to be discharged,- as corrected to the CH6-i pressure of the discharge stream at the point of the flowrate RcV '
I measurement. The maximum discharge pressure as governed by the diaphragm valve,7896,is 30 psia.
The factor of 1.5 in the denominators of equations (7) and (8) places f, on the same basis as S.
