LLNL Emergency Management Plan (EPlan) <br />Rev 27 <br />January 2022 <br /> <br /> 69 <br />4.2.14 Consequence Assessment Equipment <br />The consequence assessment workspace in the EOC has two computers with current versions of <br />plume projection software (HotSpot, EPIcode, and ALOHA computational models) for <br />calculating airborne release consequences associated with hazardous materials incidents. The <br />atmospheric release modelers in the EOC have direct connectivity to NARAC, which is located <br />at LLNL, and it is used as the secondary computational model for Operational Emergencies. <br />There is an additional computer for monitoring atmospheric (weather) data and COPS data. <br />Additionally, a laptop computer with the computational models is located in the EOC’s <br />consequence assessment workspace and is capable of providing backup. <br />4.2.15 Contamination Assessment Equipment <br />Bioassay and whole-body counting equipment for radiological contamination assessment is <br />provided by the Radiation Protection Functional Area. <br />4.2.16 Meteorological Monitoring Equipment <br />LLNL has two meteorological monitoring towers, one located at each site. In addition to LLNL’s <br />internal website for meteorological conditions, a dedicated computer located in B253 directly <br />polls and monitors these towers and serves as a redundant processor of meteorological data at <br />LLNL.
