Hazard categorization -- interpretation of DOE guidance DOE-STD-1027-92
The methodology used in the production of the Hazard Category 2 TQs is verified and presented in the above calculations (Section 3.0). The analysis is done as consistently to that prescribed in DOE-STD-1027-92 as is possible. Determining the TQ limits with the standard`s variables consistently produced the listed Hazard Category 2 TQs for the six major isotopes present in the CWC waste (100% of the isotopes attempted in their analysis) and verifies their approach without changing release fractions or receptor locations. An example of a modification of the TQ for a change in the release fraction is provided in the standard Attachment 1, pages A-6 through A-10. However, the change in TQs receptor location is another issue. Modification to the TQ because of facility location is allowed in the standard, but there is no definite approach described in the standard. This change is best represented through the change in the XIQ value. This paper provides a defensible interface with DOE guidance DOE-STD-1027-92, and an established proposed methodology for standardizing changes in the TQs because of release fractions or receptor locations. By using this information as the basis for the construction of the TQs as presented in DOE-STD-1027-92, it is determined that the GXQ program will produce TQs that are consistently conservative. The XIQ values generated with the GXQ program do not produce TQs listed in the standard, and as such, XIQs generated from the GXQ code should not be used in the determination of TQ. The information presented in this paper is expected to impact future analyses and other facilities. Specifically, the establishment of a receptor location for the final hazard category determination will be needed for future analyses. The methodology presented in this paper can be applied to the production of a hazard category threshold that takes into account different release fractions and/or receptor locations, while ensuring the expected dose to the onsite receptor will be less than 1 rem for facilities designated Hazard Category 3.
