Radioactive Material Licensed 

Element Nuclear holds a Radioactive Material License and is audited by the US Nuclear Regulatory Commission (USNRC), Nuclear Procurement Issues Committee (NUPIC), and Nuclear Industry Assessment Committee (NIAC). The lab offers full-service engineering and testing organization to support electrical and mechanical equipment qualification to the requirements of 10CFR50.49 and IEEE Standards 323 and 344.

ICAP Certified

Element Nuclear has earned IEEE’s Conformity Assessment Program (ICAP) Certification. The ICAP certification permits Element to connect directly to manufacturers through a standard of product qualification testing and standardized reporting resulting in streamlined approval processes for customers worldwide.

ICAP certification is important for expediting market adoption while reducing implementation costs. The program is specifically designed to ensure product conformity to IEEE standards, thus reducing testing burdens on manufacturers that need to meet multiple programs for different end-users or buyers. ICAP also enables trade across state and international boundaries with the assurance of operating safely and reliably within certain measurable performance criteria.
