Re: Computer Codes....

Hmmmmmmm,


     This is from:   jpreisig@aol.com.


     Let's get this straight.  There's a DOE guy asking radsafe list people about

computer codes for non-reactor applications.  OK, I'll respond, but there is

nothing US-Official about the computer codes I will list here.


     The RSICC (Radiation Shielding Information Center at Oak Ridge) has many

of these computer codes available for distribution for a moderate handling

charge.  Their Web-site has a listing of the available computer codes --- Go

Browse there --- It is fun.


     MCNP (Monte Carlo Neutral Particle Program) is for neutron and gamma

     shielding problems, reactor and non-reactor


     High Energy Physics Shielding Computer Codes:

     Casim (FermiLab)

     EGS (Electron Gamma Shower --- SLAC)

     Fluka (Available from Dr. Fasso at SLAC and/or Dr. Ferrari --- the story was

                that they would give you the code provided you only use it for

                health physics purposes --- no use for physics research)

     Lahet (Los Alamos???)

     Mars --- A Soviet Computer Code???


     Groundwater Modelling Codes:

     Modflow (USGS Code)

     Femwater/Femwaste (DOE)

     Lewa/Lewater/Lewaste (etc. --- more advanced codes available from

     Dr. George Yeh at Penn State)

     Rockworks (see their web site) has many computer codes available

     for groundwater flow and transport--- many new codes are available.


     Neutron spectrum (Unfolding???) Codes

     BON4 (EML/Brookhaven) --- an older unfolding code

     SANDII

     LOUHI

     Goldhagen at EML has a new code for deconvolution of neutron spectra.

     See Patterson & Thomas (Accelerator Health Physics) for a discussion

     of these unfolding computer codes.

     Other Unfolding Codes are available from RSICC.

     Hertel at Georgia Tech also does neutron spectrometry work.  I only do work

     like this when someone is paying me.


           I've listed some fundamental computer codes.  Most of these 

     computer codes are fairly complex.


           If you let me have some idea of what your more defined interests

     are,  I guess I could give you more information.   RSICC is a good

     source of information on all this.
