CFR Title: 

Content:
athing apparatus is provided for assurance of control room habitability in the event of occurrences such as smoke hazards. If special protection provisions are necessary for toxic gases, compliance or noncompliance with the guidelines of Regulatory Guide 1.78 should be stated. Since 6.4-18 Revision 3 - March 2007 toxic gas risk is related to site characteristics, this part of the evaluation will be completed at the COL stage of review. In meeting the positions of these regulatory guides, the applicant has demonstrated that the control room will adequately protect the control room operators and will remain habitable in accordance with 10 CFR 50.34(f)(2)(xxviii). For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for complying with specified portions of the Commission’s regulations, the staff will use the method described herein to evaluate conformance with Commission regulations. The provisions of this SRP section apply to reviews of applications submitted six months or more after the date of issuance of this SRP section, unless superseded by a later revision. VI.
