NASA is developing advanced radiation transport computer codes for human exploration missions. This consortium effort enhances Monte Carlo and deterministic codes, validating them with experimental data for space safety.

Area of Science:

  • Space science and engineering
  • Computational physics
  • Radiation shielding

Background:

  • NASA requires robust radiation transport codes for human space exploration.
  • Existing codes (HETC, FLUKA, HZETRN) need enhancements for heavy ion transport and 3D deterministic calculations.
  • A consortium of academic institutions and laboratories was formed to accelerate code development.

Purpose of the Study:

  • To accelerate the development of a standard set of radiation transport computer codes for NASA human exploration.
  • To improve existing Monte Carlo (HETC, FLUKA) and deterministic (HZETRN) codes.
  • To extend code capabilities for heavy ion transport and three-dimensional deterministic calculations.

Main Methods:

  • Enhancing Monte Carlo codes (HETC, FLUKA) with new nuclear reaction databases.
