RADSHIP-3 - A new version of the radwaste transportation radiological impact assessment code

RADSHIP-3 is a new version of the radwaste transportation radiological impact assessment code of RADSHIP-2. As compared with RADSHIP-2 code which we presented in the Waste Management '86 Symposium, the major improvement in RADSHIP-3 involves the following additional considerations: the exposure pathway to the pedestrians, the shielding effect of housing, the use of the experimental data of doses to replace the original calculation model for handlers and crewmen, and the extension of the functional mode for analyzing the radiological impact from spent fuel transportation. Besides, RADSHIP-3 code also involves a new dispersion model in sea, modifies the resuspension dose factor, and adds nuclides for the analysis of radioactive material transportation. Based on the Taipower's radwaste transportation data and with the aid of FACOM-M200 computer system, the results calculated from both RADSHIP-3 and RADSHIP-2 are compared. The comparison reveals that the annual doses computed from RADSHIP-3 are much more reasonable and acceptable than those from RADSHIP-2, particularly under the operational and environmental conditions in Taiwan
