Webof the critical mass is therefore an important underpinning to key aspects of contemporary international security. The standard derivation of the critical mass involves solv-ing a time-dependent diffusion equation with a source term, and may be found in Serber’s long-declassified Los Alamos Primer3 and in Reed’s The Physics of the Manhattan WebPower and Water uses an asset health and criticality methodology to assess the risk across the network. The methodology is loosely based on the OFGEM Network Asset Indices Methodology. 1. The methodology has allowed for the development of asset hand criticality indices for the ealth following assets classes that make up Power and Water ’s ...
