Content:
irements of 10 CFR Part 100 provides assurance that accidental releases of liquid effluents to ground and surface waters, and their adverse impact on public health and safety, will be minimized.7 III. REVIEW PROCEDURES Section 2.4.13 of the applicant's safety analysis report (SAR) is reviewed to identify any 8 missing data, information, or analysis necessary for the staff's evaluation. Applicant responses to the requested information will be evaluated using the methods outlined below, and staff positions will be developed. Resolution, if possible, of differences between the staff's and the applicant's estimation of liquid effluent dispersion will be coordinated through the LPMNRR Project Manager; and the safety evaluation report (SER) will be written accordingly. 9 10 The staff will make independent calculations of the transport capabilities and potential contamination pathways of the groundwater environment under accidental conditions with respect to existing and future users. Special attention should be directed to proposed facilities with permanent dewatering systems to assureensure that pathways created by those systems 11 have been identified. The staff will, in consultation with the Effluent Treatment Systems Branch (ETSB)PERB and SPLB, choose the accident scenarios leading to the most adverse 12 contamination of the groundwater or the surface water via the groundwater pathways. Analysis of the contamination will commence with the simplest models, such as those presented in References 8 and 21 and 22, using demonstrably conservative assumptions and coefficients. 13 Dilutions and travel times (or alternatively, concentrations directly) resulting from the preliminary analyses will then be checked by ETSBPERB to determine acceptability. If the 14 indicated concentrations of radionuclides, identified by ETSBPERB, are less than the values 15 identified in 10 CFR Part 20, Appendix B, Table II2, Column 2, no further computational 16 DRAFT Rev. 3 - April 1996 2.4.13-4
