Content:
ustification for the placement of isolation or diversion valves and radiation detectors on process piping and effluent discharge lines to ensure the timely closure of such valves upon the detection of elevated radioactivity levels, and, if part of the design, controls in monitoring deviations of in-plant dilution flow rates and terminating releases or isolating process flows when deviations exceed preset limits. 4. Design features and operational safeguards to prevent the introduction and mixing of chemical additives with ion-exchange resins to avoid the generation of exothermic reactions and explosive gas mixtures in LWMS components. 5. For plant designs with impoundment facilities and cooling ponds/canals through which LWMS radioactive effluents are discharged to unrestricted areas, descriptions of design features credited in meeting the requirements of 10 CFR 20.1406. The discussion 11.2-42 Revision 5 – January 2016 addresses how engineered design features and leakage detection monitoring methods satisfying the regulatory requirements of other Federal and state agencies also demonstrate compliance with 10 CFR 20.1406 and guidance of RG 4.21 in minimizing the contamination of plant discharges in the environment, including groundwater and surface water. 6. The listing of plant systems identified in review interfaces has been expanded to ensure that the staff’s review of radiological considerations is properly integrated with parallel and complementary evaluations conducted by other technical disciplines. For systems that contribute potential input liquid wastes to process streams and effluents managed by the LWMS, the following SRP sections were identified with technical and regulatory interfaces. The SRP Sections are 1.8, 1.9, 2.1.2, 2.4.1, 5.2.5, 5.4.8, 5.4.13, 7.1, 7.5, 7.6, 7.7, 9.1.2, 9.1.3, 9.2.3, 9.2.6, 9.3.3, 9.3.4, 10.4, 11.3, 11.4, 12.3-12.4, 13.3, 13.4, 13.5, 14.2, and 14.3 and associated BTPs as noted in each SRP section.
