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.

Workers at the Hinkley Point C nuclear construction project in the United Kingdom have completed the 49,000-ton base for the station’s second reactor, Unit C2, hitting a target date set more than four years ago, according to EDF Energy.

A new importance estimation method, which is based on the adjoint function definition, has been proposed especially for the weight window (WW) technique of MCNP, which is well known as one of the most powerful variance-reduction techniques in Monte Carlo codes. The method employs the scattering point base importance estimation, unlike the WW generator (WWG) of MCNP for the point detector function. Every scattering point has an adjoint contribution to the detector, with which a space-, energy-, and angle-dependent importance for WW could be estimated. From the numerical test calculations, the basic performance was confirmed to be better than WWG by comparing figure-of-merit values. It would be expected that the performance of WWG would be well improved by using the present method instead of the current MCNP routine of accumulating the detector contribution for the F5 tally. The presently proposed method would be a strong tool to estimate the importance applicable to various variance-reduction techniques in Monte Carlo codes.
