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.

Subsequent license renewal critical to meeting U.S. climate goals
Doug Lawrence
As the United States intensifies its efforts to combat climate change and transition to a low-carbon energy future, the role of nuclear energy has never been more critical.
One key strategy in this transition is the subsequent license renewal (SLR) of our existing nuclear power plants, allowing them to operate for up to 80 years. This extension brings several significant benefits.
Continued low-carbon energy production—By extending the life of existing nuclear power plants, we ensure a steady supply of low-carbon energy, reducing our reliance on fossil fuels and helping meet our nation’s emission reduction targets. Given that nuclear power currently provides nearly 20 percent of the U.S. electricity supply and more than half of its low-carbon electricity, maintaining this capacity is vital for a sustainable energy future.

For the GAMMA10 tandem mirror, a 28 GHz 1 MW gyrotron has been developed. The output power was achieved 1 MW in short pulse test, and 0.54 MW / 2 s in long pulse test. Moreover, the temperature rise of sapphire single disk window installed in 28 GHz 1 MW gyrotron was measured. The temperature rise was 9 K at 0.45 MW / 2 s. On the basis of the results of the performance test, the designs of 28 GHz 1 MW gyrotron have been improved to enable the operation of 1.5 ~ 2.0 MW several sec. required in GAMMA10 and NSTX, and 0.4 MW CW required in QUEST.
