3/4.3 INSTUENIATION BAsm 3/4.3.3.8 RADIQACTIVE IJOU1D EFFIDENT INSTRNENTATION The radioact.ive liquid effluent instrumentation iu provided to monitor and cuntrol, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarnVtrip setpoints for these instruments shall be calculated in accordance with the procedures in the OFFSITE DOSE CAI4UIATICH MANUAL (ODCN) to ensure that the alarnVtrip will occur prior to eFrwiing the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirments of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

3/4.3.3.9 RADIQACTIVE GASTIUS EFFIDENT INSTRNENTATION The radioactive Twus effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in yeaa effluents durirg actual or potential releases of yeas effluents. The alarnVtrip setpoints for these instruments are calculated in acxmrdance with the procedures in the OFFSITE DOSE CALCUIATICH MAtMAL (ODCM) to ensure that the alarnVtrip will occur pric'r to exrwahn the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is mnsistent with the requirments of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

3/4.3.3.10 MASTE GAS DECAY TA?E - EXPII)SIVE GAS MONITORIN3 INSTFUMENTATION The OPERABILITY of the Waste Gas Decay Tank explcsive gas monitoring instrumentation or the sanplirg and analysis program rtquired by this specification provides for the tonitoring (and controllirg) of potentially explosive gas mixtures in the Waste Gas Decay Tanks.

3/4.3.3.11 70;IC GAS SYSTEM 3 The OPERABILITY of the toxic gas systes ensurrs that sufficient capability is available to prceptly detect ard initiate protective action in the event of an accidental toxic gas release. This capability is required to protect cx]ntrol rom personnel and is consistent with guidance provided in Regulatory Guide 1.78, "Assunptions for Evaluating the Habitability of a Nuclear Power Plant IX1 ring a Postulated Chemical Release", June 1974 and Regulatory Guide 1.95, "Protection of Nuclear Pwer Plant Control Roca Operators Against an Accidental Chlorine Release", Revision 1, January 1977.

The chlorine detection system is designed so that a chlorine canoentration of 15 ppn by volume is not eW in the control rocn within 2 minutes after detection.

The sulfur dioxide detecticn system is designed so that a sulfur dioxide concentration of 40 ppu by volume is not eW in the control rocn within 2 mimtes after detection. ,
