Implementation of a True Enterprise Web Based System to Manage Low Level, Mixed, Weapons Grade, Transuranic and Hazardous Waste at Lawrence Livermore National Laboaratory
Faced with increasing challenges imposed by a new mixed waste treatment facility under construction, Lawrence Livermore National Laboratory (LLNL) embarked on a yearlong process of finding and implementing a new system to replace its existing waste tracking software. After a review of several applications, including the IWTS system in use at Idaho National Engineering and Environmental Laboratory (INEEL)a, LLNL decided to implement HazTrack. HazTrack represents a new generation of browser based enterprise level business applications that are replacing the hardcoded client-server software that has been so prevalent for the last 15 years. It is widely believed that the object-oriented application frameworks of these applications, such as the model view controller (MVC) framework for HazTrack will be at the core of leading-edge software technology in the twenty-first century. MVC applications adapt more readily to changes in business and technical requirements than do applications built using traditional programming techniques, anywhere from 2.5 to 12 times faster than propagating the same changes to programmatically implemented solutions. Because of this ability, the HazTrack team was able to rapidly modify the HazTrack application for management of radiological waste storage, including support for an unlimited number of dose conversion factors (DCF's) for calculation of Plutonium Equivalent (Pu-Eq) curies, nuclide tracking, nuclide distribution tracking, and storage area limits management. LLNL also required extensive security management features including a waste approval process with lockdown and audit trail capability that was also incorporated during the implementation, as well as a flexible access control architecture to facilitate customized user views and access rights to functions based on user groups. HazTrack supports the full range of waste handling activities including waste generation, characterization, storage, treatment, and disposal through its fully configurable data model. The application also directly supports inventory management functions with a unique location hierarchy tree, allowing users to drill into whatever level of detail they desire with respect to inventory analysis. The ability to be able to rapidly customize the system allowed the HazTrack team to respond to all of LLNL's business process requests in a reasonable time frame. This advanced design provides a software solution that is uniquely poised to deliver value today, and for many years to come.
