Content:
ary coolant activity correspond- ing to the maximum equilibrium concentration for continued full power operation as stated in the standard technical specifications for the (insert NSSS VENDOR) design. The staff will review the (insert PLANT NAME) specific technical specifications to assure that the dose guide- lines stated above are not exceeded. The results of the staff's calcu- lations are listed in Table 15.. This conclusion is based on (1) the staff review of the applicant's analysis of the radiological consequences, (2) the independent dose cal- culation by the staff using appropriate regulatory positions of Regula- tory Guide 1.5 and conservative atmospheric dispersion factors as dis- cussed in Chapter 2 of this report, and (3) the (insert NSSS VENDOR) standard technical specification for the iodine concentration in the reactor coolant consisting of a maximum allowable limit and a limit for the equilibrium concentration for continued plant operation. At the construction permit stage, the following paragraph is included in the staff's safety evaluation report: On the basis of our experience with the evaluation of steam line failure accidents for boiling water plants of similar design, we have concluded that the consequences of these accidents can be controlled by limiting the permissible primary coolant radioactivity concentrations so that potential offsite doses are small. We will include appropriate limits on the primary coolant activity concentrations in the technical specifications. V. IMPLEMENTATION The following provides guidance to applicants and licensees regarding the staff's plans for using this SRP Section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of con- formance with Commission regulations. Implementation schedules for conformance to parts of the method discussed
