ANS-56.4-1983; R1988, Pressure and Temperature Transient Analysis for light Water Reactor Containments
Wanted: Working Group Chair and working group members
Scope: This standard provides criteria and guidance for the analysis of postulated pressure and temperature transients for light water reactor (LWR) containments, including ECCS minimum backpressure analysis. Criteria and guidance are presented for the formulation of input parameters to ensure a suitably conservative design. Interfaces with passive and active systems governing the analysis, such as Emergency Core Cooling Systems (ECCS), structural heat sinks, containment fan coil units, containment spray systems, and water pressure suppression systems are identified.
ANS-56.10-1982; R1987, Subcompartment Pressure and Temperature Transient Analysis in LWRs
Wanted: Working Group Chair and working group members
Scope: This standard provides criteria for the analysis of subcompartment pressure, temperature, and flooding transients resulting from high- or moderate-energy line breaks and other events both inside and outside light water reactor primary containments. Criteria are provided for the determination of mass and energy release rates and for the formulation of input parameters to assure a conservative subcompartment or building design basis. Attention is given to the inteded use of the transient data. Interfaces with active and passive systems such as valves and structural heat sinks are treated. The qualification of equipment and design of their supports is also addressed through treatment of long-term pressure and temperature transients and also asymmetric pressure loading and its effects.
ANS-58.2-1988, Design Basis for Protection of Light Water Nuclear Power Plants Against the Effects of Postulated Pipe Rupture
Wanted: Working Group Chair and working group members
Scope: This standard addresses the design basis for the protection of light water reactor nuclear power plants from the potentially adverse effects of postulated pipe ruptures.
