The Regulatory staff has had the subject of anticipated transients without scran (ATWS) in water-cooled reactor power plants under study for sone cine. This matter was cited in the Advisory Cccmittee on Reactor Safeguards (ACRS) report and/or in the staff safety evaluation report on your application for a construction permit.
The staff has complaced its review of !.745 and has conrinAed that nessures should be taken to improve nuclear plant designs in this regard. Details of the staff review and conclusions and of the steps that should be taken to deal with ATJS are given in the staff
" Technical Raport on Anticipatad Transients Without Scra:a for Water-Coolad Power Reactors," Septenber 1973, a copy of which is enclosed for your infor=ation. The improvement measures acceptable to the staff are outlined in the staff position on ATVS, Appendi:t A, of the enclosed report in descending order of preference; that is, the "A" sections of the staff position describe tha ultimate objective. For those facilities for which the imposition of the requirements of the "A" sections is not practical, the staff vill accept the siternate approaches of the "B" or "C" sections subject to the linitations specified in the staff position. The rationale and bases for this approach are given in the enclosed report.
Acceptable nessures that should be taken for the subject facility (s) are either those in the "A" or the "B" sections of the staff position.
If there is reasonable assurance that the provisions of the "A" sections can be net satisfactorily on a schedule consistent with that of the subject facility (s), you need not analyze the consequences of ATVS.
You must, however, provide sufficient analyses and discussion to justify cmcr >
