#3.65 VERSION EUTRON EASY STONE CODE#
Substantial progress has been made in the development of TRAC, a computer code for analysis of loss-of-coolant accidents in light more » water reactors. An analytical method has been derived to assess the role of hydrodynamic instabilities in liquid-liquid interactions, and will be used to estimate the heat transferred across an unstable interface. Modeling of core disruption phenomena has progressed in several areas. A method for computing delayed neutron precursor motion has been developed and implemented in the SIMMER code for analysis of extended core motion during hypothetical core disruptive accidents. A new research program (Containment Systems Analysis) was begun during the quarter. In HTGR safety research, the independent LASL cross-section processing code system was improved to account for the doubly-heterogeneous character of the HTGR fuel.

In CTR research a complete theoretical basis has been formulated for the fusion-reaction cross-section data assessment program and a quantitative determination of Tokamak Fusion Test Reactor nuclear data needs is in progress. A Chebyshev outer iteration acceleration from the FX-2 diffusion code has been implemented in TWOTRAN-II. Promising new transport inner iteration acceleration schemes have been developed and tested.

Progress in transport theory, reactor theory, and reactor safety research for the first quarter of FY 1976 is reported.
