Content:
0.1301(e), as it relates to limits on annual doses from all sources of radioactivity released via effluent discharges and external radiation from site buildings and facilities (with single or multiple reactor units). The SRP guidance has been expanded in evaluating the implementation of standards for sites that have site-specific information on the locations of offsite dose receptors, and those that do not. 9. Clarification on the application of RG 1.143 acceptance criteria related to seismic, safety, and quality group classifications and QA provisions for SSCs of the SWMS produced during normal operation and AOOs. RG 1.143 provides guidance in assigning safety classifications to structures and waste management systems in protecting SSCs against natural phenomena and man-induced hazards. The acceptance criteria are revised to conform to 10 CFR Part 20 dose limits for members of the public and plant workers and their assumed locations in restricted areas for workers and unrestricted areas for members of the public. Also, the revised guidance refers to RG 1.206, Part I, C.I.3, Sections 3.2.1 and 3.2.2 and SRP Section 3.8.4 in identifying applicable acceptance criteria in evaluating SSCs requiring seismic design considerations and differences using the guidance in RG 1.143. 10. Additional clarification is provided on the use of automatic control features and placement of isolation dampers/valves and radiation detectors on process piping, ductwork, and effluents to ensure the timely closure of valves and dampers upon the detection of elevated radioactivity levels, and, if part of the design, controls in monitoring deviations in exhaust flow rates in terminating releases or isolating process flows when deviations exceed preset limits. Other considerations include determining whether system logic demands that a valve or damper should fail in the closed position in protecting the system from further contamination, terminating releases to the environment, or diverting
