3. NATURE OF PHYSICAL PROBLEM SOLVED

Multi-group cross sections for neutron and photon are generated by using the evaluated nuclear data, ENDF/B, JENDL and DLC-15 for transport, heat generation, and radiation damage calculations in nuclear reactors and shields. The secondary gamma-ray production cross section by the induced reaction and the Bremsstrahlung effect is also generated. The radiation transport problems for shielding designs and safety analyses of fusion and fission reactors are solved.

4. METHOD OF SOLUTION

A point-wise processing technique and the Bondarenko-type resonance self-shielding factors are adopted to generate multi-group cross sections. One- and two-dimensional Sn transport methods and three-dimensional Monte Carlo method are used  for shielding calculation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The maximum number of neutron and photon fine-groups is 200 and 50, respectively. The maximum number of angular meshes in the macroscopic cross section is 64. The energy ranges from 2.61E-5 eV to 16.74 MeV for neutrons and  from 1 KeV to 20 MeV for photons are available.

6. TYPICAL RUNNING TIME

(a) FAIR-CROSS: At step 1, an iron run with 100 neutron groups takes about 3 minutes. At step 2, a preparation of the  macroscopic cross section of water takes about 2 minutes. At  step 3, the generation of P5 cross sections takes about 5 secs. for one material.
(b) TWOWAY: A uranium run with 20 photon groups takes about 1 minute.
(c) FDEM: The production of few-group cross sections of one material takes about 10 seconds.
(d) BREM: The production of Bremsstrahlung data of one material takes about 20 seconds.
(e) DIAC: A problem of coupled neutron and photon (100n+20g) groups with 32 angular meshes and 50 spatial intervals takes 30 seconds for one material.
(f) ESPRIT: A problem of coupled neutron and photon (12n+5g) groups with 48 angular meshes and 50x50 spatial intervals takes 2 minutes for one material.
(g) MCACE: The time estimation strongly depends on the particular problem.
(h) VISUAL: The production of a graph takes less than 1 second. (i) POOL: The operation with a command takes about less than 1 second.

7. UNUSUAL FEATURES OF THE PROGRAM

The angular distribution of the group cross section is expressed by the form of Direct Angular Representation instead of finite Legendre expansion.

8. RELATED AND AUXILIARY PROGRAMS

RADHAT-V4 can produce also the cross sections compatible with the ANISN, DOT, MORSE codes by using  the FAIR-CROSS step 3.
