In this role, you will have the chance to leverage your advanced expertise to provide high-level strategic and technical guidance to operations, senior management, and regulatory bodies. You will lead complex and time-critical projects/programs that are critical to supporting LANL's mission. The NCS Division is seeking to hire a Criticality Safety Analyst 5 with a detailed understanding of the underlying principles of criticality. At this level, the specialist is expected to have been part of the development of 100s of criticality safety evaluations, technical reports, or published papers related to criticality safety. The level of technical difficulty is consistently " complex" or "novel," requiring the development of new methodologies or technical approaches. In this role you will act as an authoritative expert on all

ANSI/ANS

standards, often contributing to their development or interpretation at a national level, and should possess deep expertise in code validation, cross-section libraries, and the historical context of NCS data. In this role you will be expected to perform the following (but not limited to) job duties:

Strategic Leadership:

Advise NCSD leadership on the feasibility of proposed major projects involving fissile materials

Regulatory Insight:

Deep understanding not just of what the regulations say, but the historical intent behind DOE Orders, ANSI/ANS Standards, and NRC Guides

Institutional Memory:

Comprehensive knowledge of the history of the Laboratory's nuclear facilities, past accidents, and lessons learned

Problem Solving:

Demonstrated ability to solve problems that have stalled other senior analysts; ability to create novel solutions for unanalyzed conditions

Communication:

Elite ability to communicate complex nuclear physics concepts to non-technical senior executives and government officials to influence funding or operational decisions

Education/Experience:

Position requires a Bachelor's Degree in Nuclear Engineering, Nuclear Physics, or a related discipline from an accredited institution and 15 years of related experience; or, an equivalent combination of education and experience directly related to the occupation. A Master's degree or PhD is strongly preferred and may substitute for some experience.
