- Determination of AlarnVrrip Setpoints-for Gaseous Monitors A.
R-15 and R-22 alarm setpoints and R-14 trip setpoint will .l' be calculated based on.the most restrictive'of the following release-dose rates:. 14 1) I K o,< 500 mrem /yr F, I i i i=1 (X/Q)v 10' pci/ Ci

.= .c FNP-0-M-Oll air dose factor due to gamma emissions for M, identifie noble gas isotope i (mrad /yr-per pci/m ) from Table 3 B. Rather than calculating 3.3.3.ll.A.1 or 3.3.3.ll.A.2 using real time parameters, the actual monitor setpoints may be 7 calculated for the worse case condition (thus more conservative) count rate based on the worst isotope release-dose rate Q as follows and need not be changed, except based on.rea,pportioning of allotted release fraction from operating experience as mentioned above. From Table 3, Kr-89 would be the most restrictive isotope in either the total body or skin dose restrictions. Assuming that the total release consists of Kr-89, the skin dose equation is more t'estrictive than the whole body dose equation, and the release-dose rate limit would be calculated as: Q, = 3000 mre Wyr F, (X/Q), 10; pci/ Ci* F* (L,+1.lM, ), and Q,, = 6.9x10' Ci/sec (F,) Q,, = 4.3x10' pCi/sec (F,) Based on maximum flow rate and conservative detector efficiency, the monitor setpoints S, (cpm) may be calculated as follows: S, = 0, + b, where (c)(f,) b= monitor background count rate (cpm) c= gross monitor calibration factor (uci/ml per net cpm) u+ m, where = u= isotope concentration ( Ci/ml) in the monitor at time of grab sample calibration (Noble gas release rate calculations) f, = maximum effluent flow rate (ml/sec) net monitor reading (cpm) at time of grab sample m= calibraticn (release rate calculations) 51 Rev. 4
