Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

An application of a cylindrical discharge tube type fusion neutron beam source for medical purpose was investigated. Practicality and possibility of the medical irradiation plan were evaluated from the standpoint of engineering and medicine.Cancer treatment by BNCT (Boron Neutron Capture Therapy) was selected as an effective application to take advantage of this neutron source. Neutron transport in a phantom was calculated with the MCNP5 (Monte Carlo Neutron Particle calculation code version5), and the distribution of dose on the affected part medicated with a boron agent suggested satisfactory focusing.Since this neutron source is small size, it is designed to irradiate the affected part from many directions by crossfire irradiation. Flexibility of attitude and operation modes permits irradiation in a supine position from arbitrary directions. Because of low neutron flux, irradiation therapy is planned for multi-fractionation in a manner similar to CHART (Continuous Hyperfractionated Accelerated Radio Therapy). Crossfire irradiation and CHART will allow us to achieve new cancer therapy with a relatively lower dose rate than conventional BNCT. It causes apoptosis selectively to a cancer cell, reducing side effects and a patient's recuperation burden. This result suggests the possibility of advanced cancer treatment which improves QOL (Quality of Life) of the patients.
