ANALYSIS OF SURVEY DATA, PART 3 (PROTECTION ANALYSIS OF NFSS STRUCTURES)
Abstract
Key facilities (electric power plants, water treatment plants, hospitals, fire stations, and communications facilities) were analyzed to identify recurring special shielding problems and to determine the importance of massive, irregular special equipment in affecting radiation shielding for certain critical operations. It was found that interior contents are significant, but only in a limited number of facilities. A computer program, written in GAT symbolic language for use on a Univac 1105 Computer, for calculating the protection factor (PF) in irregularly shaped structures with numerous building construction changes was developed and is recommended for use in key facility PF calculations. A statistical study of National Fallout Survey Phase 2 building structural characteristics extracted from OCD files is reported. Included in the 844 buildings analyzed are 1030 basement shelter areas, 262 first story shelter areas, and 838 upper story shelter areas. Analyses of shelters with only roof contribution and of shelters with both ground and roof contribution are presented. A study was made to determine the effect on the PF of a shelter of ingress of fallout particles through open windows.
