Abstracts

An MCNP simulation was created for the Health Physics Instrument Laboratory (HPIL) at the Idaho National Laboratory (INL) to determine potential safe evacuation zones in the event of an uncontrolled, high activity 137Cs source during non-routine operations. An experimental comparison test case was developed to demonstrate the performance of the MCNP simulation. The experiment consisted of placing meters in the laboratory and offices during a source viewing. The experimental data was compared to the MCNP simulated results. The simulation was determined to produce usable results when meter readings and simulated detector readings fell within 21% of each other. Outlier positional data could be due to slight variations in building geometry or sources of scatter not considered in the simulations. Seven source positions were simulated, and two general evacuation zones were determined from these simulations: the lobby/front offices and loading dock areas.
