ct that the PTS-related, through-wall crack penetration mean frequency will remain less than 5 x per reactor year for the requested period of continued operation, such operation would be acceptable to the staff. In a1 1 the analyses performed, the licensee must justify that the impor- tant input values used are valid for the remaining 1 ife of the plant. Recommended Format The recommended content of plant-specific PTS safety analyses i s presented i n Chapters 1 through 10 of this guide. Use of this format by 1 icensees will help ensure the completeness of the information provided, dill assist the NRC staff i n locating the information, and will aid in shortening the time needed for the review process. If the Ticensee chooses to adopt this format, the numbering system of this guide should be followed a t least down to the section level. Certain sections may be omitted i f they are clearly unnecessary to pro- vide for comprehension of the analysis or if they are repetitive. RTeDT data from many plants (see Table P . l of Enclosure A to Ref. 4). viii Additional guidance on style, composition, and specifications of safety i analysis reports is provided in the Introduction of Revision 3 to Regulatory Guide 1.70, "Standard Format and Content of Safety Analysis Reports for Nuclear Power Pl ants (LWR Edition). " The Advisory Committee on Reactor Safeguards has been consulted concerni ng this guide and has concurred in the issuance of this regulatory guide. Any information collection activities mentioned in this regulatory guide are contained as requirements in 10 CFR Part 50, which provides the regulatory basis for this guide.
