Wellerstein's creation has garnered some popularity amongst nuclear strategists as an open source tool for calculating the costs of nuclear exchanges. [11] As of October 2024, more than 350.7 million nukes have been "dropped" on the site. [citation needed] The Nukemap was a finalist for the National Science Foundation's Visualization Challenge ...
A single explosion outside the atmosphere could blanket the area with a disk as great as 400 kilometres (250 mi) across at an altitude of about 60 kilometres (40 mi). A warhead appearing from behind this signal would be too close for the Spartan to attack it with its X-ray warhead, which relied on the explosion taking place outside the atmosphere.
A nuclear close call is an incident that might have led to at least one unintended nuclear detonation or explosion, but did not. These incidents typically involve a perceived imminent threat to a nuclear-armed country which could lead to retaliatory strikes against the perceived aggressor.
However, around 2000, according to Shelton, a member of the department within the Pentagon that is responsible for all pieces of the nuclear process was dispatched to the White House to physically ...
The effects of a nuclear explosion on its immediate vicinity are typically much more destructive and multifaceted than those caused by conventional explosives. In most cases, the energy released from a nuclear weapon detonated within the lower atmosphere can be approximately divided into four basic categories: [1]
In the context of nuclear reactors, a safety code is a computer program used to analyze the safety of a reactor, or to simulate possible accident conditions. This article appears to be a dictionary definition .
In the initial microseconds after the explosion, a fireball is formed around the bomb by the massive numbers of thermal x-rays released by the explosion process. These x-rays cannot travel very far in standard atmosphere before reacting with molecules in the air , so the result is a fireball that rapidly forms within about 10 metres (33 ft) in ...
MELCOR is a fully integrated, engineering-level computer code developed by Sandia National Laboratories for the U.S. Nuclear Regulatory Commission to model the progression of severe accidents in nuclear power plants. A broad spectrum of severe accident phenomena in both boiling and pressurized water reactors is treated in MELCOR in a unified ...
