A CRITICALITY ANALYSIS OF THE ROMASHKA REACTOR.
Abstract
A criticality analysis is performed on the Romashka reactor in an effort to establish the critical fuel loading and flux distribution. The analysis is in support of a complete engineering study designed to confirm or refute data on the Romashka configuration. Transport theory is used because of the small size and many interdependent regions of the system. A conservative S sub n equation is derived from the Boltzman transport equation. The equation is solved using rotational invariant quadrature for the differenced angular dependence. A code, RZSN, was written, and another code, TDSN, was used. Calculations were made using Hansen and Roach sixteen group cross sections with TDSN, and three group cross sections with RZSN. 49.00 and 71.08 kg. U235 loadings were found to be supercritical with TDSN. A critical mass of 55.87 kg. is predicted with RZSN. Discrepancies are found between 'known fuel loading and 'known' physical dimensions. The validity of the results is discussed, and directions for further investigation indicated. (Author)
