This calc note documents an evaluation of three options for monitoring hydrogen during waste tank intrusive activities. The three options are (1) one Combustible Gas Monitor with an operator monitoring the readout, (2) two CGMs with separate operators monitoring each gas monitor, and (3) one CGM with audible alarm, no dedicated operator monitoring readout. A comparison of the failure probabilities of the three options is provided. This Calculation Note supports the Flammable Gas Analysis for TWRS FSAR and BIO. This document is not to be used as the sole basis to authorize activities or to change authorization, safety or design bases
