MarShield has spent decades building shielding systems for nuclear facilities and research organizations across the world. Our focus in nuclear is clear. We support established plants, radioactive waste management sites, and advanced reactor projects, including small modular reactors (SMRs) and facilities using CANDU technology.
Every product we deliver is reliable, certified, and supported with documentation. MarShield solutions are engineered to perform no matter the situation they are built for.
Industry-Leading Certified Lead Pours
One of the core strengths we bring to nuclear projects is our proprietary approved nuclear lead pour process combined with best practices. very few suppliers in North America can match our combination of in-house casting capacity, regulatory compliance, and also delivery readiness.
As a Tier 1 supplier, we are trusted to deliver shielding components for everything from reactor vessels to SMR infrastructure. We cast lead from 500 to 100,000 lbs, perform radiation integrity testing, handle all fabrication and machining in-house, and ship worldwide! Our systems meet ISO 9001:2015 and CSA N299.3 standards, and include audit-ready documentation.
MarShield Fueling Growth in Nuclear Energy
MarShield was recently named an official ambassador for Canadians for CANDU. The recognition came from AtkinsRéalis, one of the world’s leading nuclear engineering firms. This designation reflects our role in supplying shielding systems that support Canada’s nuclear future; including the clean energy infrastructure tied to CANDU technology.
