a. Before CDR, it shall be verified that the final radiation values, considering the uncertainties and conservatism in the environment, shielding and parts evaluation, are compatible with the specified project-specific overall and component-specific MRDM.
NOTE 1 The RHA process defines the reporting expected at this stage (normally radiation analysis, including shielding).
NOTE 2 For components that are non-compliant with the MRDM at this stage, detailed 3-D shielding calculations can be employed to improve the fidelity of the calculation of the radiation level, or as the basis of a supplier Request for Waiver on the MRDM. The methods employed can be full and detailed sectoring or full Monte-Carlo radiation transport analysis as specified in clause 6.2.4, including a geometrical analysis of the unit, its surroundings and the spacecraft structure.
