Nuclear Engineering
SRA Professional Services Group excels in the modeling of complex radiation shielding and nuclear criticality safety problems. This includes problems in support of facility design or modification, specifying or demonstrating performance of radiation monitoring systems to show design basis or regulatory compliance (including safety related systems for routine and post-accident monitoring), predicting the performance of radiation detectors under routine or special-case conditions, and safety analyses for storage, packaging or transportation.
We have extensive experience in performing radiation transport and shielding analyses in complex environments such as commercial nuclear facilities, both for routine operations and design basis/post-accident scenarios where time-dependent source terms must be accounted for. We have also performed numerous QA Cat. I assessments for radiation monitoring systems for a number of power reactor licensees to support system modifications and upgrades, demonstrate compliance with range and overlap requirements, establish MDCs for variations in fuel performance, etc. These efforts have included the development of some unique tools to aide in the creation and verification of models of complex geometries encountered in real-world environments. Our documentation of safety-related and quality-related work and procedures for formal calculations have been commended by licensees and federal agencies alike.
SRA's engineering work is documented in formal calculations, which are subject to either our own internal quality assurance plan or the client's, whichever is preferred. Our staff has superb writing skills and is well-adept at producing detailed technical, design, or operating "basis documents". If desired, our professional staff can also act in a liaison role between a client and regulatory agencies or other stakeholders as needed.
