摘要

The program system KENOREST version 1998 will be presented, which is a useful tool for burnuprnand reactivity calculations for LWR fuel. The three-dimensional Monte Carlo code KENO-V.a isrncoupled with the one-dimensional GRS burnup program system OREST-98. The objective is tornachieve a better modelling of plutonium and actinide build-up or burnout for advanced heterogeneousrnfuel assembly designs. Further objectives are directed to reliable calculations of the pin powerrndistributions and of reactor safety parameters including axial and radial rod temperatures for fuelrnassemblies of modern design. The stand-alone-code KENO-V.a version is used without any changesrnin the program source. The OREST-98 system was developed to handle multirod problems andrnadditional burnup dependent moderator conditions which can be applied to stretch-out simulations inrnthe reactor. A new interface module RESPEFF between KENO and OREST transforms the 2-d or 3-drnKENO flux results to the one-dimensional lattice code OREST in a fully automated manner tornmaintain reaction rate balance between the codes. First results for assembly multiplication factors,rnisotope inventories and void reactivity effects are compared with OECD results. In a first versionrnKENOREST-98 is available for application.
