Thresh

DOE-STD-1027-92 Category 2 threshold (g or

Ci)3;

a unique designator for each isotope found in

the facility.

If X exceeds unity, the threshold has been exceeded.

Hazardous Chemicals. This section summarizes the screening approach for

7.2.4

hazardous materials. More detailed information is provided in Reference 3.

Hazardous Chemical Material Source Term. The source term value will

7.2.4.1

be based on a bounding release consistent with the following

assumptions:

a. No credit will be taken for mitigation, either passive or active, including

ventilation, fire suppression, building confinement, and rubble effects.

b. All materials will be released to the environment as a result of the

impact.

c. The state and form of the release will be determined as follows:

1. For gases liquefied under pressure (e.g., chlorine, ammonia,

propane), the entire contents of the vessel will be assumed to

become airborne as a puff. The same will apply to wholly gaseous

releases.

2. For liquids with a boiling point above ambient and storage

temperatures at ambient, the material will be assumed to spill

Exposure determination will not use the criticality lists for 233U, 235U, and 239Pu, since these values are unrelated

to onsite receptor dose.
