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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

As Joint European Torus (JET) is used more and more with deuterium and tritium plasmas, the machine will be irradiated by high-energy neutrons to a level that prohibits approach by human beings. All modifications and maintenance will then be carried out by remotely controlled equipment and no further attempt will be made to do hands-on work either directly or through local shielding. The remote handling equipment will comprise a series of special transporters carrying end-effectors and tools. One important transporter is a large articulated boom (arm) with nine axes of motion capable of carrying 1 tonne into the tokamak vacuum vessel and positioning it within a few millimetres. Another is the high-precision 150-tonne crane used during JET construction. These and other transporters will give access to all parts of the machine. The various end-effectors are special motorized attachments to the transporters, enabling them to carry and manipulate heavy components. An important end-effector is the (Mascot-type) force-feedback servomanipulator by which very dexterous operations can be performed and special tools placed and held in position. Most identified remote handling tasks require the combination of dexterity and load carrying provided by the manipulators in conjunction with the transporters. A range of tools, many specially designed because of space and access restrictions and the need for meticulous cleanliness, will include cutting and welding tools, largely automatic and in some cases self-propelling. Many design features have been used on JET to make remote handling possible or easier. For example, ultra-high vacuum-welded joints are made between 2-mm-thick Inconel lips, and bolted vacuum flanges have been specially developed. Remote operations will be viewed through a system of closed circuit television, some cameras being stationary and others carried on transporters. All operations will be controlled from a special central control room. A NORD 100 computer (one of JET's main array) will interconnect the control circuits between equipment and consoles and between cameras and displays. Eventually, it will also provide high-level control input to enhance operator control. Some of the remote handling equipment has been used successfully in support of hands-on work and much more will have been used and proven by the end of 1986 when the tokamak is shut down. Full remote handling will become necessary during 1990.
