ant has not followed this guidance, then the specific acceptable alternative methods used should be described in sufficient detail. The ER should use the same units of measure as used in the FSAR. The ER should include the following: • the physical layout of the site, including the location and orientation of onsite, adjacent existing operating nuclear units or co-located reactor modules or permanently shutdown units • whether the construction worker would be considered a member of the public or a radiation worker and the basis for that assumption 4.9.1 Direct Radiation Exposures In the ER, the applicant should provide the following: • The sources of direct radiation exposures: These sources should include, but not be limited to, independent spent fuel storage facilities, radioactive waste handling facilities, low-level waste storage facilities, condensate storage tanks, skyshine, and operating or permanently shutdown nuclear facilities co-located at the site. • The estimated dose rate from direct radiation to construction workers from each source and provide the assumptions and methods used for estimating the dose. • The number and principal locations of construction workers who will be exposed to the radiation sources described below and the total amount of time per year that they will spend at those locations. 4.9.2 Radiation Exposures from Gaseous Effluents In the ER, the applicant should provide the following: • Radioactive gaseous release data from the operating units, co-located units, or permanently shutdown units. The applicant should provide the location of the major gaseous effluent release points. The applicant should address the assumptions for using this release data (the year or years of data used and why this data is used or other release data such as from the design control document (DCD) for the reactor design). • An estimate of the annual total effective dose equivalent from the gaseous effluents to a construction worker, providing
