terms should be based on reactor core physics calculations and applicable reactor operating experience. The tables of source parameters, which can be placed in Chapter 12 or referenced to Chapter 11, will be acceptable if the accompanying text either in this section or other referenced sections makes it clear how the values are used in a shield design calculation or in a ventilation system design. In addition, the quantities will be acceptable if the specific values given in the tables are consistent with ANSI N237 and Regulatory Guide 1.112, for coolant and corrosion activation 13 products source terms. For PWRs designed for recycling of tritiated water, tritium concentrations in contained sources and airborne concentrations in the regions specified in item I.2 above should be based on a primary coolant concentration of 1.3 x 10 Bq/gm 14 (3.5 µCi/gm) . 15 12.2-5 DRAFT Rev. 3 - April 1996 Using the methods listed in Section II.B.2 of NUREG-0718, applicants with CP reviews already underway shall (1) perform radiation and shielding design reviews of spaces around systems that may contain highly radioactive fluids in the event of an accident and (2) implement plant designs or design modifications necessary to permit adequate access to vital areas. Applicants shall, to the extent possible, provide preliminary design information at a level consistent with that normally required at the construction permit stage of review. New applicantsApplicants for 16 CPs shall provide a general discussion of their approach to meeting the requirements by specifying the design concept selected and the supporting design bases and criteria. Applicants shall also demonstrate that the design concept is technically feasible and within the state of the art, and that there exists reasonable assurance that the requirements will be implemented properly prior to the issuance of operating licenses. Using the methods listed in Section II.B.2 of NUREG-0737, applicants for OLs shall (1) perform a
