NUCLEAR SAFETY IN CHEMICAL AND METALLURGICAL PROCESSING OF PLUTONIUM.


Book Description

A review was made of those types of criticality problems encountered in a typical plutonium processing and metal fabrication plant. A brief discussion is given of some of those criticality data which are of general interest in nuclear safety application, and of some of those data of limited application, but which are of special interest to specific processes. Curves are presented, based on multigroup diffusion theory, which show the estimated critical mass and infinite cylinder diameters for homogeneous PuO/sub 2/-water mixtures and the critical mass for Pu-- Al alloy. Applied methods of criticality control in plutonium processing and fuel element fabrication are reviewed. A list of typical administrative procedures, which have been used in effecting criticality control, is given. The proposed general program of studies for the new Hanford Plutonium Critical Mass Laboratory, which is being undertaken to obtain needed criticallty data for Pu solutions and precipitates of plutonium, is discussed.

Safe Handling and Storage of Plutonium


Book Description

This Safety Report updates IAEA Safety Series No. 39, Safe Handling of Plutonium (1974), and provides an overview of modern practices for handling and storing separated plutonium. It provides descriptions of plutonium and its properties, and of the biological effects on humans of plutonium. The principles underlying the safe design and operation of plutonium handling/storage facilities and the licensing of such facilities are also covered.

Safety Issues Associated with Plutonium Involvement in the Nuclear Fuel Cycle


Book Description

The "VOLGA" conferences, hosted in odd-numbered years by the Department of Theoretical and Experimental Reactor Physics of the Moscow Engineering Physics Institute (MEPhI), are some of the most prestigious technical meetings held in Russia. Traditionally, these conferences present the opportunity for reactor physicists from around the world to gather at MEPhI's holiday camp on the banks of the Volga river (near Tver) to exchange ideas and explore innovative concepts related to nuclear power development. In 1997, NATO became involved in the "VOLGA" meetings for the first time by co-sponsoring "VOLGA97" as an advanced research workshop. This workshop broke with tradition a bit in that the venue was moved from MEPhI's holiday camp to a location nearer Moscow. The workshop program was effectively organized in order to cover a broad range of topics relating to the theme of the meeting. Generally, the papers concerned safety related questions associated with utilizing both weapons-grade and reactor-grade plutonium in the nuclear fuel cycle, including facility requirements, licensing issues, proliferation risks, and a variety of advanced concepts for alternative fuel cycles. The program contained a total of ninety-nine papers presented in five days of sessions.




Nuclear Materials Safety Management Volume II


Book Description

LESLIE J. JARDINE Lmvrence Livermore National LaboratOlY Livermore, CA 94551 U. S. A. The Advanced Research Workshop (ARW) on Nuc1ear Materials Safety held lune 8-10, 1998, in St. Petersburg, Russia, was attended by 27 Russian experts from 14 different Russian organizations, seven European experts from six different organizations, and 14 V. S. experts from seven different organizations. The ARW was conducted at the State Education Center (SEC), a former Minatom nuc1ear training center in St. Petersburg. Thirty-three technical presentations were made using simultaneous translations. These presentations are reprinted in this volume as a formal ARW Proceedings in the NATO Science Series. The representative technical papers contained here cover nuc1ear material safety topics on the storage and disposition of excess plutonium and high enriched uranium (HEU) fissile materials, inc1uding vitrification, mixed oxide (MOX) fuel fabrication, plutonium ceramics, reprocessing, geologic disposal, transportation, and Russian regulatory processes. This AR W completed discussions by experts of the nuc1ear materials safety topics that were not covered in the previous, companion ARW on Nuc1ear Materials Safety held in Amarillo, Texas, in March 1997. These two workshops, when viewed together as a set, have addressed most nuc1ear material aspects of the storage and disposition operations required for excess HEV and plutonium (see Fig. 1, Opening Remarks).
