Talascend is currently seeking a Nuclear Software Engineer for a remote, contract opportunity with our client.

Overview

This role involves supporting the nuclear methods team by creating and updating software documentation, improving simulation tools, and assisting with licensing processes for nuclear reactors. The engineer will also design sensitivity studies, train team members, and enhance modeling capabilities.

Responsibilities

Create formal documentation of nuclear methods software requirements, design, implementation, and testing in support of licensing.
Update, improve, and/or create software to satisfy all licensing requirements during the validation and verification (V&V) process.
Incorporate additional third-party programs into the simulation ecosystem to support licensing.
Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, transport options, cross section preparation, fission product models, spatial kinetics, etc., and adjust methods as necessary.
Train and support reactor designers and developers in the use of the software suite.
Build and apply methods to assess propagation of uncertainty and their effect on safety margins.
Enhance the team's ability to build models and interpret simulation output through input tools, visualization, and reporting.

Qualifications

B.S. degree in Nuclear Engineering with 5-20 years of experience
M.S. degree in Nuclear Engineering with 3-15 years of experience
Ph.D. degree in Nuclear Engineering with 2-10 years of experience
Experience in fast reactor physics and design intuition
Understanding and executing nuclear design/analysis methodologies, including criticality, flux/power distributions, fuel management, reactivity coefficients, shielding, activation, control rod worth, detector response, and uncertainty analysis, especially for fast-neutron reactors
Excellent knowledge of reactor physics analysis methods (deterministic and stochastic transport, isotopic depletion, perturbation theory, nuclear data, kinetics, etc.)
Experience with nuclear engineering software such as DIF3D, MC2, PARTISN, MCNP, Serpent, SCALE, PARCS, APA, CASMO, DRAGON, ARMI, etc. preferred
Strong computational expertise; computers are considered an extension of the team rather than a burden
Programming skills in scientific computing languages such as Python, C++, Fortran are a bonus
Proven ability to integrate and automate simulation tools
Experience with software development tools (IDEs, version control, debuggers, documentation tools, packaging)
Knowledge of NRC interaction under ASME NQA-1 compliant QA environment preferred
Good understanding of numerical methods and applied mathematics (PDEs, stability, statistics, dynamics)
Strong technical documentation skills
Ability to deliver work on an aggressive schedule
Self-motivated with a proactive attitude to seek tasks and create value
Passion for software best practices and willingness to accept constructive criticism
Strong verbal communication skills
High level of trust, integrity, and teamwork orientation
