3. DESCRIPTION OF PROGRAM OR FUNCTION

The main aim of the (S)MURE package is to perform nuclear reactor time-evolution using successive calls to the widely-used particle transport codes MCNP or Serpent.

 

(S)MURE is an Object-Oriented package and therefore users are free to interact with it in their own way or to use the evolution controls already developed.

 

MURE also provides coupling of the neutronics (with or without fuel burn-up) and thermal-hydraulics using a sub-channel 3D code, COBRA-EN.

 

A graphical interface is provided to visualize and post-treat the results, including radiotoxicity calculations, waste heats, etc.

 

An interface to NJOY to generate cross-section in the MCNP ACE format (ENDF2ACE) is also provided in the MURE package.

 

See http://lpsc.in2p3.fr/MURE/html/MURE/MURE.html for more details.

4. METHODS

(S)MURE provides an interface to MCNP or Serpent to build complex geometries using Object-Oriented programming and/or the ability to calculate nuclear fuel depletion. Moreover, it is very easy to modify a MURE input to switch from MCNP to Serpent or vice-versa.

 

Neutron transport is performed by Monte-Carlo(MC) transport code (MCNP/MCNPX or Serpent2) and depletion is calculated using numerical integration via the Runge-Kutta algorithm. Successive MC runs and Bateman equation resolutions are performed until the end of the evolution time. Interactions during the evolution calculation allow the user to impose conditions such as power levels, constant keff, flux, control rods position, etc. ... It is easy for the user to implement their own evolution control owing to the Object-Oriented programming and inheritance mechanism.

 

Standard evolutions evaluate one-group constant reaction rates between 2 MC runs for solving the Bateman equations at each step. However, Predictor-Corrector methods can also be used, as well as "quasi-multi group" flux where reaction rates are calculated outside of MC runs from flux tallies for each cell with a highly discretized energy binning. Reaction rates in this method are calculated after each MC run using the same ACE cross-section files that were used in the neutron transport ; the advantage of this method is a large CPU time gain in MC runs(at least a factor 30).

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

For high energy physics (above 20 MeV), very little testing has been performed. To date, MURE has only been used with neutron transport (electrons, photons, protons have not been transported and fuel evolution involving reactions induced by these particles is not performed).

6. TYPICAL RUNNING TIME
  • The compilation of MURE takes about 2 minutes.

  • Run times depends mainly on MC run times ; for the evolving examples provided and using "quasi-multi group" approach, the typical run time is about 10 minutes.
