Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The Army Pulse Radiation Facility Reactor is a fast pulse, or burst, reactor generally used to provide a fast neutron environment In response to several test requirements, a number of fast neutron-to-gamma converter shields have been designed, calibrated, and placed into operation to produce a pulsed or steady-state gamma environment of ionizing radiation. The four basic converter configurations are (a) a narrow pulse converter box which has produced a maximum gamma dose rate of 3.8 × 108 rad/sec with a pulse width at half-maximum power of 50 μsec; (b) a wide pulse converter box which has produced 6.7 × 107 rad/sec at 400 μsec; (c) a narrow pulse converter cavity that has produced 7.7 × 108 rad/sec at 50 μsec; and (d) a wide pulse converter cavity that has produced 7.7 × 107 rad/sec at 1 msec. In terms of rads tissue, the gamma-to-neutron dose ratio varies from 0.1 (no converter) to ∼5; while in terms of rads (silicon), the neutron dose is almost 2 orders of magnitude less than the gamma dose.
