• Conduct advanced structural analyses, including seismic qualifications, adhering to DOE-STD-1020 and -021 and the International Building Code.

• Interpret and implement DOE Natural Phenomena Hazard codes and evaluate nuclear facility design codes, including ASCE 4, ACI 349, and AISC N690.

• Provide project management support for the installation of design changes and ensure engineering support for the fabrication of HFIR Beryllium Reflector Replacement(HBRR) components.

• Define design criteria, develop technical specifications, and review external architect/engineering submissions for compliance.

• Ensure HFIR structural specifications and drawings are consistent with the appropriate DOE and industry standards, maintaining RRD Configuration Management (SEP-0100).

• Collaborate with multidisciplinary teams to ensure constructability, operability, and effective system integration.

• Review subcontractor designs, including equipment selection, and oversee installations to meet safety and design criteria.

• Develop and approve engineering documents, including calculations, reports, and drawings to ensure quality and compliance.
