doses to determine if predicted doses are realistic and accurate: (1) Analyze radiation sources and source strength. ` Verify that all potential radiation sources associated with the adjacent nuclear facility have been identified and that their source strengths have been accurately predicted. ` Determine this on the basis of a site visit to the adjacent facility and through comparison of the facility sources and source strengths with similar facilities. NUREG-1555 4.5-6 October 1999 (2) Analyze the impacts on the work force. ` Verify that the size of the projected work force is consistent with work force data from similar projects and that the locations of workers and the duration of their stay at a particular location are consistent with the proposed plant layout, the schedule of construction, and the nature of the construction task. ` Evaluate the realism of any radiation shielding factors proposed by the applicant to take credit for work force shielding provided by the plant structures under construction. (3) Evaluate dose rates and collective doses by verifying that ` dose rates have been calculated on the basis of accepted computational models or on the basis of actual measurements. ` dose rates or doses have been calculated for those site locations where principal concentrations of construction workers will be located and that appropriate work force/work duration data have been used. ` the individual and collective doses to the construction work force are realistic and accurate. - When the evaluation establishes that there are significant differences in the determination of radiation exposure to construction workers and the applicant’s determinations of radioactive exposure, consult with the applicant to determine the reasons for these differences. - Request that additional data be provided or that calculations be repeated until the reviewer and the applicant are in reasonable agreement about the estimated individual and collective doses. The reviewer
