A critical evaluation of the design and operating performance of containment building thermal environment control systems has been undertaken. The objectives of this investigation have been to determine the principal causes of above-design containment atmosphere temperatures during normal operations and to develop recommendations for more accurate containment heat load predictions. These objectives have been achieved by compiling and evaluating information concerning operating experience with containment building thermal environmental control systems and reviewing current engineering practices applied to the design of containment building thermal environmental control systems. The project has included the independent thermal-performance testing of insulations used in nuclear containment areas. A special test facility has been designed and constructed for testing of nominal six-inch pipe insulation. Results for five types of commercial insulation have been obtained and evaluated for horizontal and vertical pipe orientations and compromised installation configurations. Also, this project has involved the development of a special computer program for the prediction of heat gain in nuclear containment buildings.
