shielded and clearly marked, indicating that potentially 91 lethal radiation fields are possible. If other than permanent shielding is used, administrative controls will be initiated and local audible and visible alarming monitors must be installed to alert personnel if temporary shielding is removed. The radiation shielding will be designed to provide protection against radiation for operating personnel, both inside and outside the plant, and for the general public. The 12.3-17 DRAFT Rev. 3 - April 1996 following are several of the shielding design features incorporated into (plant name). (List several examples of shielding design features used at plant.) Some of the criteria used by (utility) in locating penetrations in shield walls at (plant name) are: (list several shield penetration location criteria used.) These shielding techniques are designed to maintain personnel radiation exposures as low as is reasonably achievable, in accordance with the ALARA provisions of Regulatory Guides 8.8 and 8.10, and are acceptable. The general shield design methodology and source term inventories used for (plant name) are similar to those from operating reactors. The basic radiation transport analysis used for the applicants' shield design is based on (list appropriate shielding computer codes used). The applicant also used shielding information from operating nuclear plants as input data for the shield design calculations. All concrete shielding in the plant will be constructed in general compliance with Regulatory Guide 1.69. We find the shielding design and methodology presented in the (Preliminary or Final) SAR, design certification application, or COL application acceptable based on the criteria of the SRP. 92 The ventilation system at (plant name) will be designed to ensure that plant personnel are not inadvertently exposed to airborne contaminants exceeding those given in 10 CFR Part 20. The applicant intends to maintain personnel exposures as low as is reasonably
