Travel restrictions imposed by the COVID-19 pandemic are transforming, with pluses and minuses, scientific conferences around the world. Take the Coordinated Working Group Meeting (CWGM), an international event cohosted by the U.S.
Actions taken to prevent nuclear and radiation accidents or to limit their consequences.
Demonstration of a cryptographic technique that could be applicable to future nuclear disarmament agreements
The world’s nuclear enrichment programs should be under international control to prevent the development of nuclear weapons after the new arms deal with Iran expires in 10 to 15 years, said Frank von Hippel, a senior Princeton University research physicist and a former security advisor during the Clinton Administration.
“We have 10 to 15 years to strengthen the non-proliferation machine,” von Hippel said, speaking at the Ronald E. Hatcher Science on Saturday public lecture Jan. 30 at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory.
After the Chernobyl catastrophe in 1986, many asked the question why Soviet nuclear experts chose the RBMK (the “Chernobyl-type reactor”) as a standard design for implementation all over the Soviet Union. This talk will show that the choice of reactor designs rarely follows strictly technical criteria: designs are chosen not because they are the best or most functional ones available.
After detonating the first nuclear weapons in Japan, to devastating effects, the U.S. government turned swiftly to promoting the peaceable dividends of atomic energy. The first such benefit took the form of radioactive isotopes, produced in a former Manhattan Project reactor and distributed to civilian purchasers beginning in 1946. The consequences of this new supply of radioisotopes for science and medicine were profound and extensive, as illustrated by developments in biochemistry, nuclear medicine, and ecology.
After 20 months of negotiation, China, France, Germany, Great Britain, Russia and the United States reached an agreement with Iran to constrain and verify its nuclear program, in exchange for relief from international sanctions. The constraints on Iran are unprecedented among non-proliferation agreements, as are the verification procedures. Iran will be required, for 15 years, to maintain an inventory of no more than 300 kg of uranium enriched to no more than 3.67%. It will be prevented from constructing a research reactor using natural uranium.
Your task: Take apart, decontaminate, refurbish, relocate, reassemble, realign and reinstall a 75-ton neutral beam box that will add a second beam box to the National Spherical Torus Experiment-Upgrade (NSTX-U) and double the experiment’s heating power. Oh, and while you’re at it, hoist the two-story tall box over a 22-foot wall.
Editors of Foreign Policy magazine have named fusion physicist Rob Goldston, a Princeton University professor of astrophysical sciences and former director of PPPL, to its list of “100 Leading Global Thinkers of 2014.” The recognition, made Nov. 17 at a celebration in Washington, D.C., honored Goldston for his contributions to the field of nuclear arms control.
A proven system for verifying that apparent nuclear weapons slated to be dismantled contained true warheads could provide a key step toward the further reduction of nuclear arms. The system would achieve this verification while safeguarding classified information that could lead to nuclear proliferation.
