Abstract : A three-dimensional computer program, TEMP, was developed to calculate the fuel plate surface temperature distribution in the Air Force Nuclear Engineering Test Reactor (AF NETR) under steady state conditions. Approximate equations, which could be solved directly, were written to calculate the surface temperatures of the fuel plates and the bulk water temperatures. Analysis of the equations showed good agreement with results from more exact energy balance equations, which consisted of a set of simultaneous linear algebraic equations. A separate computer program, HEAT, was developed to synthesize three-dimensional heat generation data from various two-dimensional neutron source distributions produced by the neutron diffusion code, PDQ-2. TEMP is written in FORTRAN IV language for the IBM 7094 direct-couple or stand-alone system. Using threedimensional heat generation input data, it calculates the surface temperatures at a variable number of points, up to 75 across the core and up to 50 points in the vertical direction, along the centerline of each row of elements.
