Reactor Core
Design and Analysis
High Precision Work
We utilize the most appropriate and innovative approaches for nuclear reactor core analysis and design, ensuring both technical accuracy and practical applicability. For example, one of our high-quality analyses involves profiling the neutron flux distribution in a water pool research reactor, which illustrates our ability to capture fine-scale reactor physics essential for both safety and performance optimization.
​
Our methodology integrates Monte Carlo, deterministic, and hybrid approaches, applying the right method at the right stage of the problem. The decision of which approach to use is critical in achieving both computational efficiency and solution fidelity, and it is a key strength of our practice.
​
We are proficient with a comprehensive suite of industry-standard and advanced computational tools, including:
-
SERPENT – for Monte Carlo reactor physics and burnup analysis
-
SCALE – for criticality safety, shielding, and depletion calculations
-
NJOY – for nuclear data processing and cross-section generation
-
MCNP – for detailed particle transport and shielding studies
-
PENTRAN – for high-fidelity deterministic transport analysis
This breadth of capabilities allows us to design and analyze cores across the full spectrum of systems, including light water reactors (LWRs), small modular reactors (SMRs), microreactors, advanced reactors, and research reactors.
Radiation Shielding
and Dose Evaluation

Safety is our priority
We specialize in radiation shielding design and provide comprehensive regulatory related dose rate evaluations. Shielding analysis often involves solving deep penetration problems, which demand advanced expertise in particle transport simulation to ensure both accuracy and efficiency. Our approach guarantees shielding solutions that are regulatory compliant, while also being optimized for performance and cost-effectiveness.
A critical element of effective shielding analysis is the use of variance reduction techniques, which enable accurate results in complex radiation transport problems.
To address this need, we have developed our own in-house Consistent Adjoint Driven Importance Sampling (CADIS) code - wwpen2mc. This tool couples PENTRAN and MCNP, allowing for fast dose rate calculations and streamlined shielding design, giving us a unique capability to tackle challenging scenarios with confidence.
Reactor Fuel Cycle Analysis
Neutron economics is important
The reactor fuel cycle and its associated burnup characteristics are critically important from both scientific/engineering and economic perspectives. We bring over 10 years of experience in burnup, depletion, and decay analysis, applying a broad suite of computational tools, including SERPENT, ORIGEN, and our in-house developed code, BSOLVE.
​
Our expertise spans the full spectrum of reactor designs - covering light water reactors (LWRs), advanced reactors, microreactors, and small modular reactors (SMRs). With this versatility, we are able to evaluate fuel utilization, optimize core designs, and assess the long-term implications of fuel cycle strategies across both established and emerging systems.
By combining proven industry codes with our customized in-house solutions, we deliver analyses that are both highly accurate and tailored to project-specific needs, supporting design innovation, regulatory compliance, and cost-effectiveness.
