OPERATIONAL IMPLIMENTATION OF THE MARSSIM PROCESS AT THE WAYNE INTERIM STORAGE SITE

摘要

This paper describes the methodologies behind the operational implementation of the Multi AgencyrnRadiation Site Survey and Investigation Manual (MARSSIM) process at the Wayne Interim Storage Sitern(WISS). The United States Army Corps of Engineers (USACE) and Environmental Chemical Corporationrn(ECC) have implemented the MARSSIM process using various surveys producing raw data. The finalrnremedial status of a survey unit is derived through data reduction, while maintaining a high degree ofrnefficiency in the construction aspects of the remedial action. Data reduction of field measurements isrnaccomplished by merging the data outputs of a Digital Global Positioning System, an exposure rate meter,rnand laboratory analyses to produce maps which present exposure rates, elevations, survey unit boundaries,rndirect measurement locations, and sampling locations on a single map. The map serves as a data-postingrnplot and allows the project team to easily judge the survey unit’s remedial status. The operationalrnimplementation of the MARSSIM process has been successful in determining the eligibility of survey unitsrnfor final status surveys at the WISS and also in demonstrating final status radiological and chemicalrnconditions while maintaining an efficient remedial action effort.
