urce strengths determined in Item 2 above. October 1999 4.5-5 NUREG-1555 ` Accomplish this either by direct reviewer calculation of these values or by analysis to validate and accept the applicant’s data. Acceptable codes and methods include the following: - The SKYSHINE computer code, developed by Radiation Research Associates and available through the Radiation Shielding Information Center at Oak Ridge National Laboratory, is an acceptable code for calculating dose rate at distances from nitrogen-16 sources in BWR steam system components. - The GASPAR code, described in Regulatory Guide 1.109, Rev. 1, Calculation of Annual Doses to Man from Routing Releases of Reactor Effluents for the Purpose of Evaluating Compliance with CFR 50, Appendix I, (NRC 1976), is an appropriate code for calculating dose due to gaseous-effluent-plume immersion. ` The dose rate may also be determined through comparison with measured results, such as those available in EPRI NP-243 and HASL-305. ` When the applicant has used these codes or methods to predict dose rates, the reviewer’s determination may be limited to verification of the techniques of calculation and input. (5) Based on the doses or dose rates determined in Item 4 above, and the number, location, and duration of stay of construction workers determined in Item 3 above, determine the estimated individual and annual collective dose to construction workers at the proposed site. The reviewer’s evaluation of radiation exposure to construction workers involves (1) a determination that the predicted doses are realistic and accurate and (2) an evaluation of the predictions with respect to the requirements of 10 CFR 20 for doses to individuals in restricted areas. The reviewer should take the following steps for estimating the 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
