Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants. These documents are made available to the public as part of the Commission's policy to inform the nuclear Industry and the general public of regulatory procedures and policies. Standard review plans are not substitutes for regulatory guides or the Commission's regulations and compliance with them Is not required. The standard review plan sections are keyed to the Standard Format and Content of Safety Analysis Reports for Nuclear Power Plants. Not all sections of the Standard Format have a corresponding review pin. Published standard review plans will be revised periodically. as appropriate, to accommodate comments and to reflect new Informi- tion and experience. Comments and suggestions for Improvement will be considered and should be sent to the U.S. Nuclear Regulatory Commission. Office of Nuclear Reactor Regulation, Washington. D.C. 2O5. effectiveness of the system are examined. In addition, the system opera- tion and procedures are reviewed. 4. The physical location of the control room with respect to potential release points of hazardous airborne materials is reviewed. The layout of the control building is reviewed to assure that airborne materials will not enter the control room from corridors or ventilation ducts, etc. S. Radiation shielding provided by structural concrete is analyzed to deter- mine the effectiveness of shielding and structure surrounding the control room. The control building layouts.are checked to see if radiation streaming through doors or other apertures or from equipment might be a problem. 6. Independent analyses are performed to determine the radiation doses and toxic gas concentrations. Estimates of dispersion of airborne contamina- tion are made in conjunction with the assigned meteorologist. A secondary review Is performed by the Effluent Treatment Systems Branch (ETSB) and the Siting Analysis Branch (SAB) and
