RSICC CODE PACKAGE CCC-805

1. NAME AND TITLE

HEATKAU: HEATKAU Program.

2. CONTRIBUTORS

King Abdulaziz University, Saudi Arabia and Alexandria University, Egypt

3. CODING LANGUAGE AND COMPUTER

MATLAB; Windows (C00805PCX8600).

4. NATURE OF PROBLEM SOLVED

Calculations of the decay heat is of great importance for the design of the shielding of discharged fuel, the design and transport of fuel-storage flasks and the management of the resulting radioactive waste. These are relevant to safety and have large economic and legislative consequences. In the HEATKAU code, a new approach has been proposed to evaluate the decay heat power after a fission burst of a fissile nuclide for short cooling time. This method is based on the numerical solution of coupled linear differential equations that describe decays and buildups of the minor fission products (MFPs) nuclides. HEATKAU is written entirely in the MATLAB programming environment. The MATLAB data can be stored in a standard, fast and easy-access, platform- independent binary format which is easy to visualize.

5. METHOD OF SOLUTION

HEATKAU is used to calculate the number of nuclides after cooling time by solving the ordinary Bateman differential equations of initial value problem numerically using Runge-Kutta technique. The calculation of the decay heat power is straight forward in the present approach once the input database is prepared. The input data required to calculate the fission products (FPs) decay heat are categorized into the fission-yield and decay data.
