In Section 5.1 of the safety analysis report, the applicant assumed annual doses at the storage site for an array consisting of [withheld per 10 CFR 2.390] storage casks as a function of distance, and 100 % occupancy for 8,766 hours0.00887 days <br />0.213 hours <br />0.00127 weeks <br />2.91463e-4 months <br />. However, there is no information that justify the use of 8,766 hours0.00887 days <br />0.213 hours <br />0.00127 weeks <br />2.91463e-4 months <br />. For normal conditions, a bounding exposure duration assumes that an individual is present at the controlled area boundary for 1 full year (8,760 hours0.0088 days <br />0.211 hours <br />0.00126 weeks <br />2.8918e-4 months <br />). The applicant needs to justify the using an alternative exposure duration for the staff making a safety and regulatory finding.
This information is needed to determine compliance with 10 CFR 72.236(b) and (d) for sufficient radiation shielding to meet 10 CFR 72.104.
