Spectra Tech is seeking a NDA Engineer for Idaho Falls, ID. 

Position Purpose: 

Provides oversight of non-destructive assay (NDA) activities associated with transuranic (TRU) waste and low-level waste / mixed low level waste (LLW/MLLW) at the Radioactive Waste Management Complex (RWMC) as a Non-Destructive Assay Expert Technical Reviewer within the Waste Management TRU Program Organization. 

Responsibilities Include: 

• Conduct independent and expert technical reviews of NDA systems, procedures, and data analysis to ensure compliance with established protocols, standards (e.g., ANSI/ISO), and regulatory requirements. 

• Provide recommendations for improving NDA techniques, processes, and system reliability. 

• Review, revise, and approve technical procedures including operating procedures, calibration procedures, validation procedures, and quality assurance documents to ensure accuracy, clarity, and compliance with regulatory requirements. 

• Review Real-Time Radiography (RTR) recordings to identify items requiring detailed modeling, including those needing density and matrix corrections. 

• Independently perform ISOCS modeling for specific waste configurations to optimize measurement efficiency and accuracy. 

• Oversee calibration, certification, operation, and assist in troubleshooting of NDA instruments, including RBAS (Retrieval Box Assay System), ISOCS (In Situ Object Counting Systems), SGRS (SWEPP Gamma-Ray Spectrometer), WAGS (Waste Assay Gamma-Ray Spectrometer), and DAS (Drum Assay Systems). 

• Support instrument operations to ensure accurate and reliable performance across all NDA systems. 

• Collaborate with engineering and operations organizations to diagnose and resolve instrument or performance issues. 

• Support software validation and testing in support of the NDA systems. 

• Calculate measurement control data and review and approve control charts to detect trends or anomalies impacting measurement quality. 

• Validate NDA measurement data and batch data reports in the Waste Tracking System (WTS) to ensure accuracy, completeness, and compliance.

• Perform validation of data generated by NDA systems to ensure measurement quality and compliance. 

• Review NDA activities for adherence to DOE, EPA, and WIPP Waste Acceptance Criteria (WAC). 

• Support audits by DOE Carlsbad Field Office, EPA, and other regulatory bodies, including preparation and on-site participation. 

• Support implementation of criticality safety controls and criticality working requirements related to NDA and waste characterization activities.
