Job Description:
System One is seeking a Function Containment and Radionuclide
Transport Engineer for a remote work model. long-term contract
opportunity, with our client, based out of Bellevue, WA. The
Functional Containment and Radionuclide Transport Engineer is
responsible for performing radionuclide transport calculations
within systems and buildings to support effluent releases and to
develop mechanistic source terms for postulated accidents
(equivalent to Level-2 PRA). They will work directly with other
nuclear safety and licensing staff to ensure technical and
regulatory requirements for nuclear safety and worker protection
are met. Other engineering activities include, but are not limited
to, contributing to the development of computational methodologies
and models, contributing to software commercial grade dedication,
participating in hazard analysis, participating to Phenomena
Identification and Ranking Table (PIRT) exercises, participating to
Structures, Systems and Components (SSC) classification, developing
analytical methods, performing analysis of functional containment
and radionuclide transport as well as verification and validation
activities. Responsibilities Develops analytical models for
quantification of radiological source terms in the gaseous and
liquid effluents during normal operation and anticipated
operational occurrences Develops analytical models for ex-core
radionuclide sources such as radwaste systems, spent fuel, and
auxiliary purification systems. Supports the development of
mechanistic (accident) source term methods for postulated accidents
Develop analytical models for containment performance including
mass and energy release and subsequent leak rates. Provide inputs
to radiological consequence models Perform technical work to
support regulatory submittals and NRC interactions Support
establishment of overall functional containment strategy to meet
risk-informed performance-based effluent and accidental releases
including development of Specified Acceptable Radionuclide Release
Design Limits. Work with an interdisciplinary team of engineers to
establish functional, reliability, performance, safety, and quality
requirements for SSC that support the radionuclide containment
function as well as support the overall design Establish and
maintain documentation of model development and analysis results.
Perform engineering reviews of analyses and other engineering
design media. May support analysis and recommend design solutions
for worker radiological protection including control room
habitability May perform radiological dose assessments to support
the ALARA program Key Qualifications and Skills Experience with
performing containment analysis and radionuclide transport
assessments using codes such as GOTHIC, RADTRAD, MELCOR, SRT or
similar tools is required. Familiarity with functional containment
approach is a plus. Familiarity with nuclear design, regulatory
requirements, and risk-informed performance-based technology
guidance for Non-Light Water Reactors is required. Knowledgeable of
PRA principles and familiar with the ASME/ANS Non-Light Water PRA
standard a plus Experience with SFR safety analysis is highly
desirable. Experience with other reactor designs can be considered
when differentiating candidates. Demonstrated strong quantitative,
analytical, modeling and reporting skills. Understanding of NQA-1
requirements associated with analysis and software management as
well as experience working under a quality assurance programs.
Experience in working in multi-disciplinary engineering teams to
address engineering challenges. Strong software engineering skills
in any language is a plus. The successful candidate will possess a
high degree of trust and integrity, communicate openly and display
respect and a desire to foster teamwork. Ref: 161-Managed Staffing
