Thermalhydraulics

• Light Water Properties Download (fast, accurate curve fits to the 1984 NRC/NBS steam tables). Contributed by Bill Garland.
• Heavy Water Properties.
• CANDU Primary Heat Transfer System Heat Duty Diagram as discussed in Chapter 3 Heat Transport System Thermalhydraulics (pdf 280kb), course EP716
  • simplified numerical calculation (xls 55kb) as per Section 3.9 of Chapter 3
  • simplified analytical calculation (xls 17kb) as per Section 3.8 of Chapter 3
• CANDU fuel channel 1-D temperature calculation (xls 90kb)
• CANDU 6 heat balance / power calculation based on measured temperatures, pressures and flows, with error propagation estimates (xlsx17 kb)
• Friction Factors
  • 1phase1 (xlsx 448kb) - Single Phase Friction Factors for MNR Thermalhydraulic Modelling.
• System Failure Modeling – Simple Example

Reactor Physics

• Point Kinetics
  • PKSIM (zipped), a point kinetics simulation program (including C source code and sample input). It is a straightforward implementation and is nothing fancy. Contributed by Bill Garland.
  • PK1 - similar to PKSIM but in a desktop simulator format created using LabWindows/CVI.
  • Pk.xlsm (xlsm 51kb) - a point kinetics simulation using Excel spreadsheet and VBA. Easy to play with and modify.
  • EXKIN (zipped), another point kinetics program, this time in FORTRAN (exe only) driven by MS Excel 95. Very user friendly. Contributed by Peter Chan.
• Xenon Poisoning
  • XE1 - Xe kinetics simulation in a desktop simulator format created using LabWindows/CVI.
  • Xe.xlsm (xlsm 27kb) - Xenon and iodine kinetics simulation using Excel spreadsheet and VBA. Easy to play with and modify.
• CELL and FLUX (zipped), a simple cell and core code set for reactor physics flux calculations (including a readme file, C source code and sample input). The CELL code is a cell property preparation code using a WIMS generated material properties library (a 4 group library is supplied). With it you can define cells for mixtures of materials and perform group collapsing. FLUX uses the resulting cell definitions (or you can provide your own) and an input specified core geometry to calculate the flux. It is diffusion based, 2D, steady state or transient, and multigroup. These are straightforward implementations and are nothing fancy. Used in the fourth year reactor analysis course, EP4D3 at McMaster University. Contributed by Bill Garland. Data flow diagram for the cell and flux codes:
• Decay Heat
  • Decayhe1 (xlsx 467kb) - Decay Heat Estimates for the McMaster Nuclear Reactor.
• System Failure Modeling – Simple Example

Simulators

• PCTRAN, Commercial. A DOS based PC package for PWR, BWR CANDU and others that can simulate a variety of accident and transient conditions for nuclear power plants. Graphic mimic of the Nuclear Steam Supply System (NSSS), interactive control.
• MNRSIM - McMaster Nuclear Simulator built by Dave Gilbert created using LabWindows/CVI. It is a work in progress but it is shaping up nicely. Watch and listen (exe 23Mb) to a presentationon on MNRSIM or view the slides (pdf 416kb) Go Dave!

Nuclear Data

• Radiation Decay - By Charles Hacker. Provides radioactive decay information for 497 Radionuclides. Data provided includes the half life, radioactive daughter nuclides, decay chain series, probabilities per decay, and Decay product energies for alphas, betas, positrons, electrons, X-rays, and photons. In case his site should disappear, you can download the program from this site.
• PREPRO, a preprocessor for handling neutron and photon cross section data from the IAEA Nuclear Data Centre. Use this tool suite to generate cross section data for assignments and codes. Nice!
• Rad Pro calculator - Rad Pro Calculator online performs many nuclear calculations that are useful to the health physicist, radiological researcher, radiochemist, radiation safety officer, health physics technician (HP) and other professionals in radiation physics and radiological engineering. It calculates, among other things, radioactivty units conversions (SI and US customary) and gamma emitter dose rate and activity.

Compilers

• C programming with Miracle C, a compiler that light and easy to use - just the ticket for beginners. It runs under Windows (95/98/ME/NT/2000) and compiles for MSDOS or a DOS box. It provides a multi-window development environment with integrated compiler and linker, and online helpfile documentation. The full install is only about 750 kb! Source code to the compiler is supplied upon registration (US$25), enabling the user to modify and customise it. There is a nice Miracle C Installation and Use Guide. I captured it as a pdf file (115 kb) which you may fine useful for study purposes. This guide gets you going and takes you through your first program step by step.
• LCC-Win32: a free compiler system for Windows by Jacob Navia. This is a nice C compiler that has a better development environment that Micacle C. The debugger is great. The system is self contained; you do not need anything else to get started programming in C in the Win32 environment. You get, in a 2.9 Mb download:
  • Code generator (compiler, assembler, linker, resource compiler, librarian)
  • Integrated development environment with editor, debugger, make file generation, resource editor, etc.
  • User manual (approx 240 pages, Microsoft Word format), and technical documentation (approx 260 pages, same format).
  • All the binaries and the associated header files etc, are contained in an auto-installable executable that will create all the needed directory structures. The full install is about 12 Mb.
• FORTRAN links:
  • GNU Fortran G77 for Win32 - a free Fortran compiler and associated libraries, including plotting.
  • Professional Programmer's Guide to Fortran77 (suggested by Victor Snell, AECL).
  • FORTRAN FAQ - part way down you'll find a link to a free book by Chivers and Sleightholme. It is quite easy reading. It covers syntax well but does not cover programme structure (suggested by Victor Snell, AECL).
  • The Salford FTN95 compiler is free for personal or evaluation use and includes an interactive development tool. May be run under windows or via a command line. Thanks go to Paul Hinman (paul#dot#hinman#at#shaw#dot#ca) for the link.
  • Other Fortran compilers.

Miscellaneous

• WinMetric, Commercial. Cost = $99, evaluation download available. WinMetric consists of a unit converter, a list of equations, physical constants and physical properties, a periodic table of the elements with 14 physical properties for each element, full tables of the thermodynamic and transport properties of steam and air, a psychrometric calculator, a pressure drop calculator. Easy to use. Handy reference.
• The Calculator Home Page - get the free Calc98 engineering, scientific and financial calculator for Windows using the RPN (Reverse Polish Notation).
• Excel VBA calculation example (xlsm 22kb) - Consider using Excel VBA as a computing tool.
• Virus infection dynamics - an aside not directly related to nulear but it does offer an opportunity to explore how to think about risky phenomena.
