Shielding Analysis Engineer

About this role

Thanks for your interest in Oklo! We are searching for a Shielding Analysis Engineer to join our engineering team.

Position Description

The Shielding Analysis Engineer is responsible for defining, developing, and executing radiation shielding and radiation transport analyses to support reactor design, plant layout, performance evaluation, and safety assurance.

This role involves working closely with the broader design team to solicit and capture requirements, establish the scope of shielding evaluations, and implement appropriate source term, activation, dose rate, streaming, and shielding models and methods.

Areas of analysis include, but are not limited to, radiation transport, material activation, source term development, dose assessment, and shielding design optimization.

The engineer will also support verification and validation activities and contribute to licensing and regulatory interactions by providing technically sound and defensible shielding analyses.

Specific responsibilities may include:

•
Perform the complete range of actions involved in supporting shielding design, radiation transport analysis, and dose assessment for using Monte Carlo and supporting codes on Oklo facilities.

•
Perform calculations and analyses in Monte Carlo based radiation transport codes such as MCNP, SCALE, OpenMC, and Serpent.

•
Perform source term, activation, streaming, skyshine, and dose-rate analyses using appropriate Monte Carlo and deterministic methods.

•
Support the qualification and verification of shielding analyses, including validation against experiments, benchmarks, and operationally relevant radiation measurements.

•
Be aware of and familiar with radiation shielding, radiation transport, and fast reactor core design and analysis work being performed internationally, as well as related benchmark calculations and experiments being performed internationally.

•
Provide technical feedback to quick-iterating design teams.

•
Document work using modern tools and techniques, and write well-written, thoughtful technical reports.

Minimum Qualifications:

If you have experience and expertise in reactor design, radiation transport, or shielding analysis, apply! We also think the following are good indicators of qualifications to do this job:

•
Bachelor's, Master's, or PhD in a technical field, such as nuclear engineering, with experience in reactor design, radiation transport, shielding analysis, or radiation protection (Master's or PhD may be preferable).

•
Fluency with Python.

•
Proficiency with high performance computing systems.

•
Experience with fast reactor design, shielding design, or radiation protection analysis is highly recommended.

•
Proficiency with radiation transport tools such as MCNP, SCALE, OpenMC, and Serpent is highly recommended.

•
Proficiency with variance reduction techniques such as weight windows, surface read/write, source biasing, and CADIS/FW-CADIS methods is recommended.

•
Experience with source-term generation, activation, dose-rate calculations, and shielding design methods is recommended.

•
Proficiency with CAD software such as SolidWorks is a plus.
