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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Proton radiography is an imaging technique with potential application in proton radiation therapy. The ability of a proton radiograph to differentiate anatomical features in the thoracic region, such as heart, lung, rib cage, shoulder, etc., was qualitatively investigated using Monte Carlo simulations. A patient with a stage IIIA non-small cell lung cancer tumor located in the right upper lobe and mediastinum was considered for this study. The GEANT4 Monte Carlo toolkit was used to simulate proton transport through a proton nozzle and through the lung area of the patient, registering in a phase-space file the entry and exit energy, position, and motion direction of each proton. The Monte Carlo simulation ran a total of 10 million histories with the highest deliverable energy of 235 MeV at the Francis H. Burr Proton Therapy Center. The proton radiograph was then generated independently of the Monte Carlo simulation, using a numerical algorithm to input the proton position, direction of motion, and energy kept in the entry and exit phase-space files. The proton radiograph was compared to the standard portal X-ray image for tissue and tumor contrast, and for visibility relative to the background lung tissue. The preliminary results with GEANT4 showed that the proton radiography can produce images with good spatial resolution and excellent soft tissue contrast, resulting in better tumor edge localization within a soft tissue background region such as the lung.
