Program to determine in-reactor performance of B and W fuels. Cladding creep collapse

An analytical procedure is described along with the experimental data developed by Babcock and Wilcox (B and W) to determine the minimum time to collapse for B and W fuel cladding under operating conditions. The resultant computer code is referred to as CROV. The analytical procedure was developed from the engineering principles of shell theory. The experimental data consisted of two types. One type of data was employed to develop empirical creep constants applicable to B and W fuel cladding. The other type of data provided an experimental comparison for the ovalities and collapse times predicted by CROV. 9 references. (U.S.)
