Job description

Idaho Falls, ID, United States (On-site)

Job Description

Idaho National Laboratory is seeking an intern to support the development and evaluation of gamma-ray computed tomography (CT) methods for nuclear fuel examination. Using fission-product source distributions provided by the INL research team, you will develop Monte Carlo radiation transport simulations representative of INL's Gamma CT instruments and generate simulated projection data (sinograms) for selected source distributions and instrument geometries.

Because these imaging systems have low geometric efficiency, you will also implement and evaluate variance-reduction methods, including importance sampling, to improve computational efficiency while maintaining accurate results. Using the simulated projection data, you will apply image-reconstruction algorithms and evaluate image quality using quantitative metrics such as signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). You will also investigate how acquisition parameters including the number of angular projections, detector dwell time, and filtering methods affect reconstruction quality.

This project will provide hands‑on experience in Monte Carlo radiation transport, gamma‑ray imaging, computed tomography, image reconstruction, and quantitative image‑quality analysis.

This team works a 4x10 schedule onsite at our Materials and Fuels Complex campus. Start date and duration of internship vary based on project and student availability. You may be eligible for course credit for this internship.

Minimum Qualifications

Enrolled full‑time in a PhD program at an ABET‑accredited college/university studying Nuclear Engineering
A minimum overall 3.0 GPA
Must have previously completed a BEA internship within the MFC Reactors and Chief Technologist Group
Current Resume or CV
Unofficial Transcripts (include current and completed degree programs)
Current class schedule and number of credits

Preferred Qualifications

Experience with MCNP, SCALE, or ADVANTG

Compensation
