PERSENT (Perturbation Theory Codes)

 

Standard Code Description

  1. Name of Program:
    PERSENT
  2. Computer for Which Program is Designed and Other Machine Version Packages Available:
    Linux, Unix, Windows OS
  3. Description of Problem or Function:
    PERSENT is a perturbation and sensitivity calculation code for conventional assembly homogenized diffusion and transport problems. It is built on the VARIANT option of DIF3D. For perturbation, calculations can be done that consider typical material and cross section perturbations. For sensitivity calculations, users can compute eigenvalue, reaction rate, reaction rate ratio, power fraction, reactivity worth, prompt neutron lifetime, and beta effective sensitivities to the microscopic reactions: gamma, alpha, proton, deuteron, tritium, fission, nu, and P0 & P1 scatter cross sections.
  4. Restrictions on the Complexity of the Problems:
    Cartesian and hexagonal geometries that DIF3D is able to deal with
  5. Typical Running Time:
    The running time depends on a problem size to solve. Use a single core.
  6. Unusual Features of the Program:
    Generation of perturbation and sensitivity parameters for uncertainty analysis
  7. Related and Auxiliary Programs:
    Neutron diffusion or transport solution: DIF3D, PROTEUS-NODAL

  11. Operating System:
    Linux
  12. Other Programming or Operating Information or Restrictions:
