RADIOACTIVE EFFLUENTS BASES GASEOUS RAQMASTE TREATMENT (Continued)
This specification applies to the release of radioactive materials in.
gaseous effluents from each reactor unit at the site.
4 The minimum analysis frequency of 4/H (i.e. at least 4 times per month at intervals no greater than 9 days and a minimum of 48 times a year) is used for certain radioactive gaseous waste sampling in Table 4. 11-2.
This will eliminate taking double samples when quarterly and weekly samples are required at the same time.
3/4.11-2. 5 EXPLOSIVE GAS MIXTURE This specification is provided to ensure that the concentration of potentially explosive gas mixtures contained in the waste gas holdup system ls maintained below the flammability limits of hydrogen and oxygen.
(Automatic control features are included in the system to prevent the hydrogen and oxygen concentrations from reaching these flammability limits.
These automatic control features include isolation of the source of hydrogen and/or oxygen, or injection of dilutants to reduce the concentration below the flammability limits.}
Main-taining the concentration of hydrogen and oxygen below their flammability limits provides assurance that, the releases of raaioactive materials will be controlled in conformance with the requirements of General Design Criterion 60 of Appendix A
to 10 CFR Part 50.
3/4. 11.2.6 GAS STORAGE TANKS This specification considers postulated radioactive releases due to a waste gas system leak or failure, and limits the quantity of radioactivity contained in each pressurized gas storage tank in the GASEOUS RADMASTE SYSTEM to assure that a release would be substantially below the guidelines of 10 CFR part, 100 for a postulated event.
Restricting the quantity of radioactivity contained in eacn gas storage tank provides assurance that in the event or an uncontrolled release oi the tank's contents, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest exclusion area boundary will not exceed 0.5 rem.
This is consistent with Standard Review Plan 11.3, Brancn Technical Position FTSB 11-5, "Postulated Radioactive Releases Due to a Maste Gas System Leak or Failure,"
in NUREG-0800, July 1981.
3/4.11.3 SOLID RADIOACTIVE )PASTE This specification addresses the requirements of General Design Criterion 60 of Appendix A to 10 CFR Part 50.
The process parameters included in establishing the PROCESS CONTROL PROGRAH may include, but are not limited to waste type, waste pH, waste/liquid/solidification agent/catalyst
- ratios, waste oil content, waste principal chemical constituents, and mixing and curing times.

CONTROLLED HY US INSTRUMENTATIOil BASES 3/4. 3. 3. 7-LOOSE" PART DETECTION INSTRUMENTATION The OPERABILITY of the loose-part detection instrumentation ensures that.
sufficient capability is available to detect loose metallic parts in the primary system and avoid or mitigate damage to primary system components.
The allowable out-of-service times and surveillance requirements are consistent with the recommendations of Regulatory Guide 1.133, "Loose-Part Detection Program for the Primary System of Light-Mater-Cooled Reactors,"
May 1981.
3/4. 3. 3. 8 RADIOACTIYE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor.
and
- control, as applicable, the releases of radioactive materials in gaseous ef luents during actual or potential releases of gaseous effluents.
The alarm/trip set-points for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the alarm/trip wi'1l occur prior to exceeding the limits of 10 CFR Part 20.
This instrumentation also includes provisions for monitoring (and controlling) the concentrations of potentially explosive gas mixtures in the GASEOUS RADMASTE SYSTEM.
The OPERA-BILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.
There are two separate radioactive gaseous effluent monitoring systems:
the low range effluent monitors for normal plant radioactive gaseous effluents and the high range effluent monitors for post-accident plant radioactive aaseous effluents.
The low range monitors operate at all times until the concentration of radioactivity in the effluent becomes too high during post.-accident conditions.
The high range monitors only operate when the concentration of radioactivity in the effluent is above the setpoint in the low range monitors.
