RSIC CODE PACKAGE PSR-537

 

1.   NAME AND TITLE

            TRISTAN-IJS:  Steady-State Axial Temperature and Flow Velocity in Triga Channel.

 

2.   CONTRIBUTOR

Jozef Stefan Institute, Reactor Physics Division and Agencija za radioaktivne odpadke, Ljubljana, Slovenia, through the OECD Nuclear Energy Agency Data Bank, Issy‑les-Moulineaux, France.

 

3.   CODING LANGUAGE AND COMPUTER

            Fortran 77; Pentium Personal Computers (P00537IBMPC00).

 

4.   NATURE OF PROBLEM SOLVED

TRISTAN-IJS is a computer program for calculating steady-state axial temperature distribution and flow velocity through a vertical coolant channel in low power TRIGA reactor core, cooled by natural circulation. It is designed for steady-state thermohydraulic analysis of TRIGA research reactors operating at a low power level of 1-2 MW.

 

5.   METHOD OF SOLUTION

            Stable operating point is calculated by iterations according to Bernoulli equation.

 

6.   RESTRICTIONS OR LIMITATIONS

None noted.

 

7.   TYPICAL RUNNING TIME

Less than 1 minute in the sample case on Windows PC.

 

8.   COMPUTER HARDWARE REQUIREMENTS

      The included executable was tested on Intel Windows personal computers under the Windows XP SP2 and Vista operating systems.

 

9.   COMPUTER SOFTWARE REQUIREMENTS

At RSICC, TRISTAN-IJS was compiled on a Pentium 4 running Windows XP SP2 with the Intel 9.0 ifort compiler for 32-bit Windows applications. This executable and the Fortran source code are included in the package.

RSICC obtained TRISTAN-IJS through the NEADB, where it is distributed as IAEA1337/01. The code was originally compiled under Windows NT using Lahey F77L-EM/32 Version 5.20, which is incompatible with WindowsXP. RSICC compiled the source and replaced the original executable with the Intel 9.0 executable.
