HGS has proven technical capability and governance programs that have successfully analyzed, designed, constructed, and commissioned facilities, systems, structures and components (SSCs) for federal and non-governmental nuclear installations, including providing operational and field support for diagnosing and resolving operational problems. Our capabilities and our technical and governance procedures ensure that our manufactured products and engineering and analytical services meet the requirements of the respective federal regulations, agency guidance and requirements, and the relevant terms of the federal contract.
Design and analysis activities for new and old SSCs often require multi-disciplinary technical expertise which is a distinguishing feature of the HGS’ pool of technical resources. To design or troubleshoot SSCs, the Company can call upon its deep bench of highly trained engineers equipped with cutting-edge expertise in an array of disciplines including mechanical design, civil design, soil mechanics, structural analysis, thermal-hydraulic analysis, shielding evaluation, reactor physics, and criticality safety analysis.
The Department of Energy’s (DOE’s) approach to nuclear safety is defined to Title 10, Code of Federal Regulations Part 830, “Nuclear Safety Management.” Because of the broad diversity of the DOE facilities and their processes, HGS capabilities include development of the safety and design bases of a project “from scratch” using DOE’s regulatory framework. Our programs will apply applicable DOE guidance and requirements for implementing Part 830 such that a typical nuclear design project begins with development of a safety design strategy (SDS) for determining the functional performance and capabilities to be provided by the SSC; the design features to achieve them; and the strategy for assuring the necessary levels of operational safety. Roughly in parallel, the hazards associated with the design and its operation are identified, analyzed, safety functions are identified, their significance (safety categories) are determined and, where needed, controls developed to prevent or mitigate adverse consequences. DOE Conceptual Safety Design Reports (CSDRs), Preliminary and final Documented Safety Analysis (PDSAs, DSAs) and Technical Safety Requirements (TSRs) are prepared, iterated with the customer, and implemented to control the configuration and operating envelopes of the SSC as the facility or SSCs are commissioned. For DOE, this is accomplished in accordance with DOE Orders, Directives and guidance such as DOE STD-3009-94, Nuclear Facility Documented Safety Analysis and DOE STD-1189-08, Integrating Safety into Design.
HGS also has extensive project experience within NRC’s regulatory framework for establishing licensing and design bases. Under NRC definitive and prescriptive approach to defining safety and design requirements by regulatory and guidance, our work is accomplished in accordance with the provisions of NRC regulations, Standard Review Plans, Regulatory Guides, and other NRC staff-issued documents that provide acceptable methods and approaches to comply with their regulations. Again, our governance and technical processes are focused and have demonstrated HGS’s ability to deliver the safety, quality, and performance of our products and services.
