[en] The purpose of this technical report is to document the estimation of radiological releases and risks for postulated accidents at the E-Area Vaults (EAV). The results of this analysis will be used to support the E-Area Vault Burial Ground Operations Safety Analysis Report (SAR) Addendum. The results of these calculations indicate that the maximum individual offsite effective dose equivalent (EDE) for postulated accidents at the EAV is 0.26 rem for the Intermediate Level Non-Tritium Vault (ILNTV) non-combustible container rupture. The maximum individual onsite EDE is 2.3 rem for the same accident scenario. The onsite and offsite risks for each accident were calculated as the product of the accident frequency (per year) and the associated consequences (EDE). All calculated risks were found to be within the WSRC risk acceptance guidelines
