Criticality (status) - Wikipedia
In the operation of a nuclear reactor, criticality or critical state is the state in which a nuclear chain reaction is self-sustaining but not growing
Nuclear Waste Imaging and Spent Fuel Verification by Muon Tomography
This paper explores the use of cosmic ray muons to image the contents of shielded containers and detect high-Z special nuclear materials inside them. Cosmic ray muons are a naturally occurring form of radiation, are highly penetrating and exhibit lar...
Cosmic ray muon computed tomography of spent nuclear fuel in dry storage casks
Radiography with cosmic ray muon scattering has proven to be a successful method of imaging nuclear material through heavy shielding. Of particular interest is monitoring dry storage casks for diversion of plutonium contained in spent reactor fuel. U...
Determining Reactor Flux from Xenon-136 and Cesium-135 in Spent Fuel
The ability to infer the reactor flux from spent fuel or seized fissile material would enhance the tools of nuclear forensics and nuclear nonproliferation significantly. We show that reactor flux can be inferred from the ratios of xenon-136 to xenon-...
The use of CEvNS to monitor spent nuclear fuel
Increasing amounts of spent nuclear fuel are stored in dry storage casks for prolonged periods of time. To date no effective technology exists to re-verify cask contents should this become necessary. We explore the applicability of Coherent-Elastic N...
Russia’s Nuclear-Powered Burevestnik Missile: Implications for Missile ...
Nov 4, 2025 · Nuclear-powered cruise missiles are not a new idea—they’re just a bad idea. While Russia’s Burevestnik missile is grabbing headlines, it does not fundamentally change Russia’s ability …
IAEA Completes Integrated Safety Assessment Mission for Bolivia's …
Feb 19, 2025 · An International Atomic Energy Agency (IAEA) team of experts said that the Agency for Nuclear Energy of Bolivia (ABEN), operator of Bolivia's first nuclear research reactor (RB‑01) that is …
The 1986 Chornobyl nuclear power plant accident
Jun 13, 2013 · On 26 April 1986, the Number Four reactor at the Chornobyl Nuclear Power Plant in what then was the Soviet Union during improper testing at low-power, resulted in loss of control that led to …
Broken Arrows: Radiological hazards from nuclear warhead accidents (the Minot USAF base nu…
According to numerous press reports, in 2007 at Minot US Air Force Base six AGM-129 Advanced Cruise Missiles mistakenly armed with W80-1 thermonuclear warheads were loaded on a B-52H heavy bomber in place of six unarmed AGM-129 missiles that were a...
Nuclear fission in intense laser fields
Rapid-advancing intense laser technologies enable the possibility of a direct laser-nucleus coupling. In this paper the effect of intense laser fields on a series of nuclear fission processes, including proton decay, alpha decay, and cluster decay, i...
New insights in laser-generated ultra-intense gamma-ray and neutron sources for nuclear ap…
Ultra-intense MeV photon and neutron beams are indispensable tools in many research fields such as nuclear, atomic and material science as well as in medical and biophysical applications. For astrophysical applications aimed for laboratory investigat...
Computational-Experimental Investigation of a Fission Thermal Probe in TREAT
The development of nuclear fuels requires unsteady/transient testing for design process and qualification under postulated accident conditions. Breach, rupture, fracture, melting, and other fuel failure modes may occur during the use of nuclear fuels...

Dressed Qubits in Nuclear Spin Baths
We present a method to encode a \textit{dressed} qubit into the product state of an electron spin localized in quantum dot and its surrounding nuclear spins via a dressing transformation. In this scheme, the hyperfine coupling and a portion of nucl...
Why Iran but not North Korea?
Why America bombed Iranian nuclear sites, but doesnt do anything about North Korea that also has nuclear weapons?...

Irradiation of TiBe12 and CrBe12 with He+ ions and ex-situ transmission electron microscop…
Ti and Cr beryllides are materials of potential importance as neutron multipliers for tritium breeding in nuclear fusion reactors. The n-to-2n transmutation reaction also produces tritium and helium, which form bubbles. Neutron irradiation from fusio...
GANIL Status report
The GANIL-Spiral facility (Caen, France) is dedicated to the acceleration of heavy ion beams for nuclear physics, atomic physics, radiobiology and material irradiation. The production of radioactive ion beams for nuclear physics studies represents...
Dipole resonances and the nuclear Schiff moment
The nuclear Schiff moment creates a mechanism of transfer of the violation of parity and time-reversal invariance by weak interaction in nuclei into the atomic electric dipole moment. We point out an additional contribution to the Schiff moment gener...
Nuclear Schiff Moments and CP Violation
This paper reviews the calculation of nuclear Schiff moments, which one must know in order to interpret experiments that search for time-reversal-violating electric dipole moments in certain atoms and molecules. After briefly reviewing the connection...
