Nuclear Shielding & Criticality Engineer

Talascend is currently seeking an experienced Nuclear Shielding and Criticality Engineer for a long-term contract career opportunity, 100% remote.

Candidates may reside anywhere in the continental USA; but must be eligible to work for any employer without sponsorship now, or in the future.

OVERVIEW:

Our client is developing a Molten Chloride Fast Reactor (MCFR). The Nuclear Shielding & Criticality Engineer will use the latest in MCNP to perform radiation shielding calculations for both gammas and neutrons. You bring experience in criticality calculations and safety to this team as well.

RESPONSIBILITIES:

• Perform radiation shielding design and analysis for advanced nuclear reactors, including calculating dose rates, activation rates, neutron fluence rates, and energy deposition rates.
• Develop radiation sources based on material activation analysis for non-fuel in-vessel components.
• Perform criticality calculations and develop upper subcritical limits (USLs).
• Establish and maintain formal documentation of analysis results.

REQUIREMENTS:

• B.S. degree in Nuclear Engineering from an accredited university. Advanced degree is preferred.
• 5+ years of nuclear analysis methods related experience in MCNP, criticality safety and combined experience with performing radiation shielding calculations for both gammas and neutrons are required.
• Must be familiar with variance reduction using MCNP, and features such as surface source read/write, mesh tallies, and weight windows. Familiarity with ADVANTG for weight windows generation is a plus.
• Excellent written and verbal and communication skills required. As you will be working within published regulatory guidelines and following requirements for documenting calculations.
• Experience working under NQA-1 quality program desired
