1. Device characteristics - fission/fusion ratio - device yield - various device incasement methods DELETEnN ‘aw sone DELETED 2. Emplacement methods - stemming material, etc. 3. Experiments associated with the event, - for example: tunnel shot with line-of-sight pipe from device chamber to main tunnel shaft. - well-type shot with line-of-sight pipe. - various emplacements of sampling lines to obtain samples of device residue. These and other factors affect the potential consequences of a shot. They are all considered in deciding whether an event can be safely conducted and establishing the necessary safety Support program. DOE ARCHIVE These parameters have a bearing only on the pre-event evaluation or potential hazards analysis, although their analysis determines the type and
