Outline
RFSP-IST- Reactor Fuelling Simulation Program Industry Standard
Toolset
AECL SourceForge (SF) Foundry - Delivery of software products and services over the
internet.
CANDU Basic Lattice Cell
basic building block of the CANDU designDimensions 1 lattice pitch by 1 lattice pitch by 1 fuel-bundle length (28.575 cm x 28.575 cm x 49.53 cm)
Basic lattice cell components:1-bundle length of pressure tube, with fuel bundle and heavy-water coolantcalandria tube, concentric with the pressure tube and separated from it by an isolating gas gapassociated volume of heavy-water moderator
(not to scale)
CANDU Basic Lattice Cell (with 37-Element Fuel)
CANDU Reactivity Devices
Reactor core reactivity devices
zone controllers and adjusters, which are positioned interstitially between fuel channels
Reactor-Physics Computational Scheme
CANDU neutronics consists of three stages.
-Computer programs developed to perform calculations
Three Stages:Lattice-Cell Calculation (POWDERPUFS-V or WIMS-IST)Reactivity-Device (Supercell) Calculation (DRAGON)Finite-Core Calculation (RFSP-IST)
RFSP
RFSP-IST (Reactor Fuelling Simulation Program - Industry Standard Toolset)
Computer program to do neutronics (static, quasistatic, and dynamic) calculations for CANDU reactors
RFSP can calculate both static and kinetic neutron flux and power distributions in the core in two energy groups and three dimensions.
RFSP can be used to simulate reactor operations, including refuelling and burnup steps.
Modular in nature
Each module specific function. model definition time‑average and instantaneous calculations of the in‑core flux power distributions kinetics calculations
execute independently of one another and share data through the RFSP direct‑access file
RFSP
RFSPRFSP-IST (Reactor Fuelling Simulation Program - Industry Standard Toolset)
Calculates the static 3-D flux distribution in the core by either of two methods:
the solution of the finite‑difference diffusion equation in two energy groups
a flux‑mapping method, using a modal expansion of the flux in a series of pre‑calculated flux modes
RFSP Release VerificationRFSP code
Running simulations in UNIXDeveloped KORN Shell scripts and Fortran
executables to automate generation of verification reports
Comparison of data through different RFSP versions to AECL Versions [ACR Feature requests]
Platforms used: HP, LINUX, PC
RFSP Release VerificationVerification involves the comparison of the outputs
generated by different versions. Results generated by two versions be similar, Behaves consistently with respect to both
platforms. The comparison is in the form of a percent
difference of key parameters i.e. reactivity and maximum bundle and channel powers.
Verification Summary
RFSP Report Contains all modifications Results provided with different compilers were not the
same Errors related to numerical rounding or truncation
• % difference > 0.5%, parameter is flagged
Comparisons showed that no unacceptable differences were found

RFSP WEBSITE
• Hummingbird Exceed – Visualize desktop of a Linux Session
Many updates to the RFSP website made using the software development environment ECLIPSE Platform Version 3.0.1 on the RedHat LINUX operating system.
Open source PHP scripting programming language was used for website development.
Using VNCViewer remote desktop environment.• VNCViewer is an Xt-based client application for the VNC
(Virtual Network Computing) system. VNC software is cross-platform, allowing remote control between different types of computer.
