| Popis: | In order to establish a technique which will properly account for the LMFBR core deformation under various reactor operating conditions, two separate computer programs have been developed, and coupled together. The first of the two, “FEMCRP”, is a finite element creep analysis code for a long, straight, hexagonal tube. The second program owes its origin to BOX-V developed by ANL, but was later modified considerably by the authors to include the effect of stainless steel swelling. The computer program, HICODEM, is the cross between the two. It can analyze the equilibrium configuration of the core consisting of fuel subassemblies of various burnup histories, with corresponding degree of swelling and creep. The code can assume a mechanical clamping on the periphery of the core during the power operation, and after a desired length of time, it can bring the entire core to the refueling temperature and unclamp the constraint, the resultant equilibrium core configuration being successively obtained. The results can be obtained by the ordinary digital print out and/or by the X−Y plotter as the vertical cross section of the core. HICODEM code has been succesfully checked out against available literature and against itself by taking different computational paths. The code consists of about 6,000 source cards, and takes about 20 minutes on a HITAC 5020F (or IBM 360) for a typical computation simulating one entire refueling cycle (about 146 days for Monju). |
