This is another leap forward in the cleanup of one of Europe's most hazardous buildings that has posed an environmental risk for decades. (bechtel.com)
Starting retrievals is a fantastic achievement and as a team we are pleased to be supporting Sellafield to retrieve the decades-old waste, package it safely, and dispose of it permanently - reducing the hazard on the Sellafield site to create a safe and secure world, together. (bechtel.com)

The example of the Kyrgyz Republic presents an integral case study of radioactive waste dangers and could help to address similar issues in other territories. (nti.org)

Regulatory document REGDOC-3.1.1, Reporting Requirements for Nuclear Power Plants , sets out the timing and information that nuclear power plant licensees are required to report to the CNSC to support the conditions of applicable power reactor operating licences (PROL). (gc.ca)
It is building the first reactor in Finland and the 1,600MW plant is scheduled to start commercial operation in 2009. (edie.net)
The Indian Point Nuclear Power Plant required a lot of sandbags and reinforcements around it to keep the Mississippi River from flooding the reactor plant. (backdoorsurvival.com)
When I was in charge of an engineering department for a fully independent small reactor plant, my entire department was about 40 people and we operated and maintained that plant 24 hours per day for months at a time without any outside assistance. (atomicinsights.com)

Biological threats can include bioterrorism, infectious disease outbreaks, or accidental release of dangerous pathogens. (j3seven.com)

Like nuclear power, which has 'peaceful' and 'wartime' uses, radioisotopes can be deadly when released unexpectedly into the environment in large doses but can also be used for medicinal purposes . (scientificamerican.com)
Depleted uranium is left over after uranium has been enriched for use in nuclear reactors or weapons, blurring the line between peaceful and wartime uses of nuclear power. (scientificamerican.com)
These recycled metals should only be used under control conditions at DOE sites or possibly in the construction of nuclear reactors and associated equipment at nuclear power plants,' the recommendation states. (wise-uranium.org)
How do reactors that don't even exist and won't until the 2030s - assuming the proposed designs even work - provide power and system reliability? (neis.org)
The advantage of the technology developed by BARC is that it assumes heavy water as the moderator in power reactors when most of those in the West (including Russia) -- with the exception of Canada -- use light water. (ccnr.org)
Curiously, there seems to exist some confusion regarding how classified the project is, but scientists at the Nuclear Power Corporation (NPC), the government controlled organization that constructs and runs India's commercial power reactors, remain tight-lipped on the entire issue. (ccnr.org)
The decommissioned reactor vessel from Portland General Electric's Trojan Nuclear Power Station in Oregon is buried in 1999 at the Hanford Nuclear Reservation near Richland. (columbian.com)
SMRs are either the cleaner, safer, cheaper future of nuclear power or the return of the same old bundle of hazards, dressed up in newly attractive camouflage. (columbian.com)
This efficient energy source comes from the 98 nuclear power reactors dotted around 30 states in the US. (conserve-energy-future.com)
There are many reasons why I believe smaller reactors that can be operated by smaller teams in distributed power generation scenarios will solve many of the challenges faced by the very large machines built under the mantra of "economy of scale. (atomicinsights.com)

If past examples are any indicator, the "consenting" communities are likely to be those most deprived of resources, especially Indigenous communities and communities of color, who may feel pressured to accept the DOE largesse along with the deadly hazards of living alongside high-level radioactive waste. (nukewatchinfo.org)

But as dangerous as they are, the toxic vapors Garza's crew encountered aren't necessarily the tanks' worst hazard. (uchicago.edu)
The extent and rate of build-up of both flammable and toxic releases can be affected by properties of the released gas and the process or location of the release. (europa.eu)
