sign plans, particularly to identify new arrangements, improved designs, unusual shield thicknesses, a new or modified shield thickness calculational procedure, unusual assumptions in the calculation, placement of radiation monitors. RAB-evaluates the adequacy of the applicant's shielding design on the basis of acceptable radiation shielding codes. RAB may make verifying check calculations with SDC, G3, QAD, or MORSE, whichever is specifically applicable to the situation. For the FSAR the reviewer considers any changes in the design that might necessitate changes in operating procedures to accommodate a chanpad radiation zone or a different location of equipment. The reviewer determines whether the applicant has followed the guidance of the referenced regulatory guides and industry standards, both by comparison of the applicant's methods with the information in the guides and by the applicant's reference to any such guides or to proposed alternatives. The reviewer evaluates whether the alternatives are equivalent to or improvements on the methods cited in the referenced regulatory guides. Otherwise, alternatives are likely to be disapproved. Based on the review, RAB may request additional information 6r request the applicant to reevaluate the radiation protection design features to meet the acceptance criteria of subsection II of this SRP section.
