Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

UNF-ST&DARDS is being developed to provide the ability to perform automated analysis of spent nuclear fuel (SNF) storage, transportation, and disposal systems. UNF-ST&DARDS provides a database for storing and preserving SNF data and streamlines various analyses using the data from the database for time-dependent characterization of SNF and related systems (e.g., dry storage system). UNF-ST&DARDS allows for modelling the variation of cask payload burnup, enrichments, and cooling times through a flexible GUI. This tutorial will include 1) discussions on various data need for realistic SNF characterizations and demonstration of the data import processes in UNF-ST&DARDS, 2) assembly-specific, time-dependent depletion and decay analyses, 3) as-loaded (using actual cask loading maps) criticality and shielding analyses of currently loaded casks for storage, transportation, and disposal (over disposal time periods), 4) discussion of as-loaded analyses to support licensing/certification of dry SNF systems, 5) misload analysis methodology to support as-loaded criticality analysis, 6) design-basis criticality and shielding analyses using user-defined loading patterns and fuel assembly types, and 7) dry storage loading optimization using UNF-ST&DARDS. The tutorial/demonstration is open to all registered meeting attendees who signed up at the time of registration. Attendees have no requirements to watch the demonstration, however, an RSICC license for UNF-ST&DARDS and SCALE is necessary if they would like to follow along.
