Molten Salt Nuclear Graphite Qualification Plan

Natura will partner with Oak Ridge National Laboratory (ORNL) to develop a graphite qualification plan and identify performance characteristics and development plans to design, approve, and perform graphite irradiations with fuel-bearing salts. The plan will look at utilizing the High Flux Isotope Reactor (HFIR) at ORNL which would allow for rapid neutron irradiation of graphite (7-10 dpa per year) in a future irradiation test outside of the voucher scope. The project will also include the development of fuel-bearing, molten salt irradiation capsules to support the future irradiation test.

Reference Data for Determination of Carbon and Oxygen Content in TRISO Fuel Kernels

Standard Nuclear is developing alternative methods to assess the carbon and oxygen content in the fuel kernel. They will partner with Oak Ridge National Laboratory (ORNL) to perform LECO testing in the Low Activation Materials Development and Analysis (LAMDA) laboratory to help baseline and calibrate the method. By developing an alternative method for assessing carbon and oxygen content in TRISO fuel kernels, this project will reduce the cost and inefficiencies associated with current destructive testing methods.

International Nuclear Safeguards and Security by Design Workshop

The Department of Energy’s National Nuclear Security Administration (NNSA) is organizing a three-day Safeguards and Security by Design (SSeBD) Workshop (September 10-12, 2024) in Oak Ridge, TN for U.S. advanced and small modular reactor vendors and developers that are seeking to deploy their technologies in the U.S. and internationally. The workshop will focus on the technical measures that can be applied during the planning and design stages to increase physical protection and security system efficacy to meet international security guidance and highlight how designers can meet international nuclear safeguards requirements, which are different from the United States’ requirements.

Real-Time Generation Risk Assessment (GRA) Model for Commercial Nuclear Power Plant, Entergy Operations

Entergy will partner with Oak Ridge National Laboratory (ORNL) to implement real-time Generation Risk Assessment (GRA) modeling to address these issues. ORNL’s unique experience in implementing GRA models combined with the use of their Operational Performance Risk Assessment (OPRA) software will be used to integrate the model with real-time data. Entergy will roll out the model at one of its operating plants an if successful look to expand to other plants in their fleet.
