What it’s about: An exhilarating nuclear disaster, narrowly averted by a future president, which is shockingly an actual life occasion and never an early ’90s Harrison Ford film. And its setting, an Ottawa analysis facility that ran a number of nuclear reactors from 1944 till 2018.

Strangest reality: The Queen Of England is the last word authority on Canadian nuclear energy. In 2007, Chalk River’s Nationwide Analysis Common reactor (NRU) was shut down for routine upkeep, and the Canadian Nuclear Security Fee (CNSC) determined to increase the shutdown so as to add extra backup energy programs. The one downside was, as talked about final week, Chalk River—particularly the NRU—offers almost all the medical isotopes for North America, and shutting down the reactor prompted a worldwide scarcity.

Canada’s Home Of Commons overruled the CNSC and ordered the reactor to be restarted for 120 days, and then-Prime Minister Stephen Harper criticized the shutdown. Security Fee CEO Linda Eager was fired, and the reactor was restarted after lower than a month offline, security considerations be damned. However the order to reopen wasn’t official till it acquired Royal Assent. Whereas Canada has formally been impartial since 1982 (and impartial throughout the British Commonwealth since 1867), the nation was too well mannered to cease asking for royal approval for its legal guidelines. Her Majesty doesn’t seem in individual, however the Governor Basic acts in her stead, in a ceremony that includes folks with titles like Mace Bearer (this isn’t figurative; the bearer holds an precise mace), and Usher Of The Black Rod, which might additionally make a reasonably bitchin’ black metallic album title.

Factor we had been happiest to be taught: Future president Jimmy Carter saved the day. In 1952, one of many different reactors, the NRX, underwent what’s euphemistically known as a “energy tour,” and is the truth is an uncontrolled chain response. A part of the reactor’s coolant was misplaced, the core was broken, and in consequence the gasoline rods had been overheated. The reactor melted down, a sequence of explosions additional broken the reactor, and 4,500 tons of radioactive water flooded the basement. The U.S. Navy despatched in a 26-man rescue crew, primarily based in Schenectady, New York, led by a younger Jimmy Carter. The cleanup was profitable sufficient that inside two years, the reactor was again on-line.

Factor we had been unhappiest to be taught: Carter’s victory over the atom was short-lived. Solely six years after the NRX melted down, the NRU suffered a gasoline rupture, which began a hearth, overheating some gasoline rods. The mechanical arm charged with pulling the uranium rods out of the reactor broke when the uranium caught hearth. The rod broke and fell down into the reactor, irradiating the entire constructing. When the constructing was ventilated, the encircling space was additionally contaminated. Laboratory employees put out the hearth with buckets of moist sand, however the aftermath required one other joint civilian-military cleanup effort. Fortunately, nobody suffered long-term well being results. And surprisingly, after two accidents in six years, the plant was put again on-line and ran with out incident till the 2007 shutdown.

Additionally noteworthy: The Chalk River advanced has extra than simply these two reactors. The primary reactor on the web site was the Zero Power Experimental Pile Reactor (ZEEP), which opened in 1943 and shuttered in 1973. NRX was constructed 4 years later, and NRU ten years after that. Additionally in 1957 got here the Pool Take a look at Reactor (PTR). The Zero Power Deuterium Reactor (ZED) arrived in 1960, as did the Nuclear Energy Demonstration reactor (NPD). 1970 introduced SLOWPOKE, the Secure Low-Energy Kritical [sic] Experiment Reactor, which by some means moved to the College Of Toronto the next yr. However earlier than it did, Chalk River had seven completely different nuclear reactors going.

Greatest hyperlink to elsewhere on Wikipedia: Onerous to beat the Manhattan Project, the most important top-secret science experiment in historical past. Whereas the Los Alamos lab run by Robert Oppenheimer is the placement one thinks of for the mission, the joint U.S.-U.Okay.-Canadian effort unfold throughout greater than 30 websites throughout all three nations, and at its peak employed 130,000 folks, all of whom managed to maintain a lid on the mission lengthy sufficient for the atomic bomb to be developed and dropped on Japan to finish WWII.

Additional Down the Wormhole: One factor we’ve by no means talked about about Wikipedia is that pages that cope with particular places typically have geographic coordinates. On this case, the Chalk River lab is situated at 46.05ºN by 77.36ºW. The concept of a coordinate system is credited to Eratosthenes of Cyrene within the third century B.C. It was tinkered with and improved by way of the centuries till the U.S. hosted a 25-country summit to standardize longitude and latitude in 1884. Twenty-two of the nations agreed on the system that’s grow to be the world normal, with 0º set on the Royal Observatory in Greenwich, England.

The Observatory itself is now a museum, and whereas it’s one among England’s most important historic websites, it will probably’t be mentioned to be the rockingest. That distinction goes to Handel & Hendrix, a museum that collectively celebrates two musical giants who had been next-door neighbors, give or take 210 years. We’ll sing “Hallelujah” after which kiss the sky subsequent week.
