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.

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.

An analysis has been made of the use of multiple nuclear explosives in a single emplacement hole for the stimulation of the production of natural gas from a low permeability gas reservoir. Both simultaneous and sequential firing have been considered. Although the physical effects of simultaneous or sequential firing are difficult to quantitatively predict, it is shown that for an area where the gas deposit is thick (>500 ft) and the maximum yield is limited by seismic considerations, the use of sequential firing is significantly more advantageous from an economic viewpoint. An economic analysis of a specific gas formation was made, assuming the use of sequential explosions for the commercial development of an entire gas field. Assuming a wellhead gas price of 30¢ per 1000 ft3, the internal rate of return on the required investment varied from 13 to 27%, depending on the properties of the reservoir. Before these projections can be realized, a large number of technical and operational problems must be solved.
