SUPERENERGY2; steady-state LMFBR core analysis. [CDC7600,CYBER175; FORTRAN IV]

Technical Report ·
OSTI ID:6343972

SUPERENERGY2 was written to perform steady-state, thermal-hydraulic design and performance analyses on multiple LMFBR assemblies. The code automatically generates the geometry and nodes for any number of single- or double-ducted assembly types based on a few critical dimensions. Radial node options are either a standard fine-mesh subchannel layout based on the number of fuel pins or a lumped representation of one to eight rings formed at the user's request. Assemblies may be coupled for interassembly heat transfer effects, using either a conduction or flow solution in the interassembly gap. Generalized boundary conditions can be applied to the noncoupled bundle faces, and a duct wall gamma heating option is available. The code contains default sodium and stainless steel property correlations; mixing parameter flowsplit, and heat transfer correlations; all can be overriden by input data. The calculated bundle temperature profiles are printed in map form at specified locations for ease of use. SUPERENERGY2 can compute problems ranging from a single bundle operating condition parametric study to a large core sector problem determining the effect of interassembly heat transfer on the duct temperature profile for core restraint analysis.CDC7600,CYBER175; FORTRAN IV; SCOPE 2.1, NOS 1.3; Storage requirements vary with problem size. For the given dimensions 53K words of small core memory (SCM) and 66K of large core memory (LCM) are required. The program can also be executed entirely in SCM. If this is the case 155,000 (octal) words of memory are required. The auxiliary program CONVERT requires 21,000 (octal) words of memory for execution.
