Nuclear Engineer

The role

The Nuclear Engineer will develop nuclear engineering solutions for the Kaleidos microreactor. This includes radiation shielding, criticality safety, accident dose consequence, reactor physics modeling, and transient analysis.

What you will do

• Ownership of nuclear design and analysis
• Shielding: operational dose and shutdown activation analysis, waste categorization, and alignment of shielding design
• Neutronics: analysis of ex-vessel reactor fluxes and energy deposition, criticality safety, and V&V of nuclear toolbox and reactor models
• Accident and Dose Consequence: radiological dose consequence from different accident scenarios
• Transient Analysis: run coupled neutronics and thermal calculations
• Collect requirements and provide expertise and feedback to engineers in other functional areas
• Other nuclear design and analysis duties as assigned

Required qualifications

• Bachelor’s degree in nuclear engineering or equivalent degree from an accredited institution
• 1-2+ years of nuclear engineering industry experience (MS equivalent to 2 yrs)
• Experience with radiation transport methods, including with codes such as MCNP/OpenMC/Serpent
• Proficient in at least one of the following programming languages: Python, C++, C#, FORTRAN, or another scientific computing language
• Basic knowledge of thermal hydraulic principles
• Self-motivated with strong organizational, written, and oral communication skills
• Experience working in an engineering organization and developing high-quality work

Nice to have

• Experience with variance reduction techniques and associated software (Attila4MC and/or ADVANTG)
• Strong experience with OpenMC, Serpent, MCNP, Attila4MC, MOOSE, RELAP, Pronghorn, GRIFFIN, or other similar nuclear software packages
• Competency in distributed software development processes and high-performance computing environments
• Familiarity with CAD design software (NX, SolidWorks, and/or SpaceClaim)
• Familiarity with dose consequence methods and software such as MAACS or NRC-RADTRAN
• At least 1 year of software development or scripting experience
• Hands-on experience designing hardware and/or performing tests

Benefits

• Substantial incentive stock plan for all full-time employees
• Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans
• One Medical: Sponsored memberships for employees and their dependents
• Vision: 100% top tier plan coverage + 50% for dependents
• Dental: 100% top tier plan coverage, orthodontia extra, 50% for dependents
• Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits
• 8-weeks of paid parental leave for all parents
• Additional paid pregnancy leave for CA employees
• Nuclear Engineering Certificate Program: 100% covered educational program with Penn State University, for eligible employees
• Daily catered lunch
• Free snacks and drinks
• Flexible PTO policy
