Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

BWXT announces nuclear manufacturing plant expansion
BWX Technologies announced today plans to expand and add advanced manufacturing equipment to its manufacturing plant in Cambridge, Ontario, Canada.
A $36.3 million USD ($50M CAD) expansion will increase the plant’s size by 25 percent—to 280,000 square feet—and another $21.7 million USD ($30M CAD) will be spent on new equipment to increase and accelerate its output of large nuclear components. The investment will increase capacity and create more than 200 long-term jobs for skilled workers, engineers, and support staff, according to the company.

Lithium metatitanate (Li2TiO3) is one of the candidate tritium-breeder materials for the ITER test blanket module (TBM) and the DEMO blanket. It will be used as the tritium-breeder material for the Indian lead-lithium–cooled ceramic breeder concept of the TBM to be tested in ITER. Thermal conductivity is one of the most important parameters in the design of TBMs using ceramic materials. The design of breeder blankets is strongly affected by the low values of the thermal conductivity and density of ceramic breeder pebble beds. A significant increase in both quantities would enhance thermal performance and lead to an increased tritium-breeding ratio. Thermal transport properties of Li2TiO3 were measured using the laser flash method, which determines the thermal diffusivity from the transient temperature rise measured at one side of a pellet with laser pulse heating at the other side. The thermal conductivity of Li2TiO3 pellets was then estimated from the experimentally obtained thermal diffusivity values. Finite element analysis using ANSYS software was performed to simulate the transient thermal measurements, and the results were compared with those obtained by the laser flash method. The experimental and simulation results were found to be in good agreement. The experimental details and ANSYS simulation are presented in this paper.
