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.

When your test capsule is the test: ORNL’s 3D-printed rabbit
Oak Ridge National Laboratory has, for the first time, designed, printed, and irradiated a specimen capsule—or rabbit capsule—for use in its High Flux Isotope Reactor (HFIR), the Department of Energy announced on January 15.

An implicit numerical scheme is developed to compute the transient one-dimensional flow of a two-phase mixture described by an unequal phase velocity (nonhomogeneous) model. This method is based on the modified FLASH-4 technique, but it suffers few of the drawbacks of other solution techniques recently used in the RELAP 4 and RETRAN computer codes. Significant advantages of the method are its consistency, stability, and ease of programming for complicated flow networks. The numerical scheme has been incorporated into a computer code and used to calculate three flow situations: a single-phase gas (ideal gas shock tube) a single-phase liquid (subcooled water blowdown) a two-phase blowdown (the Edwards experiment).
