small, 3MW experimental BWR called SL-1 (Stationary Low-Power Plant No.
1) in Idaho was destroyed on January 3, 1961, when a control rod was removed
At 9:01pm, alarms sounded at the fire stations and security headquarters of the U.S. National Reactor Testing Station where the reactor was located. Investigation found two operators dead (third died later), and detected high radiation levels in the building.
A careful examination of the remains of the core and the vessel concluded that the control rod was manually withdrawn by about 50 centimeters (40 centimeters would have been enough to make the reactor critical), largely increasing the reactivity. The resulting power surge caused the reactor power to reach 20,000MW in about .01 seconds, causing the plate-type fuel to melt. The molten fuel interacted with the water in the vessel, producing an explosive formation of steam that caused the water above the core to rise with such force that when it hit the lid of the pressure vessel, the vessel itself rose 3 meters in the air before dropping back down.
The SL-1 accident was the first fatal nuclear
accident in the United States. The men killed in the incident were two
Army Specialists, John Byrnes, age 25 and Richard McKinley, age 27, and
Richard Legg, a 25 year old Navy Electricians Mate. Richard McKinley
was interred in Arlington National Cemetery. John Byrnes and Richard
Legg were buried in their hometowns in New York and Michigan.
Per the records at Arlington National Cemetery,
the body, which was contaminated with long-life radioactive isotopes, cannot
be moved from its location in Section 31 without the approval of the Atomic
Energy Commission (United States Energy Department). It is believed that
the "accident" at the Idaho plant was a suicide by one of the operators
working at the site on the night of the explosion.

SUBJECT: Internment of Radioactive Remains
1. Radioactive remains of SP4 Richard L. McKinley were interred at Arlington National Cemetery on 25 January 1961.
2. It is desired that the following remark be placed onthe permanent record, DA Form 2122, Record of Internment:
"Victim of nuclear accident. Body is contaminated with long-life radio-active isotopes. Under no circumstances will the body be moved from this location without prior approval of the Atomic Energy Commission in consultation with this headquarters."

NUCLEAR POWER: BURNING CALIFORNIA ISSUE
15 Years After Fatal Accident,
It Is A Factor In Tuesday's Primary
By Thomas O'Toole, Washington Post Staff Writer
John Byrnes is buried in his hometown of Utica, New York; Richard Legg in his hometown of Kingston, Michigan, and Richard McKinley in Arlington National Cemetery.
As far apart as they are, their graves are strikingly similar. The caskets are lined with lead and sunk in concrete. The coffins rest inside metal vaults driven as far as 10 feet into the ground. Concrete has been poured on top of the vaults so that relatives of the dead men can freely visit and care for their grave sites.
Byrnes, Legg and McKinley were given such elaborate burials because they died together in what is still history's only fatal atomic power accident. Now more than 15 years old, it was an accident that killed two of them at once and the third two hours later -- a tragedy that left their bones and bodies radioactive.
Their deaths are a part of a burning debate about whether the nation should turn to nuclear energy for its electricity for the next 50 years.
The nuclear debate has inflamed parts of 30
states, dividing communities and even households. Some divorces have been
set in motion in California and New York by family nuclear differences.
Sit-ins, walk-ins, pray-ins and shout-ins have been held for and against
nuclear energy. There are at least 50 different bumper stickers damning
or praising atomic power.
Brattleboro, Vermont (UPI) -- A 1961 Idaho nuclear reactor "accident" that killed three people resulted from sabotage by an employee bent on a murder-suicide, says an internal government memo published yesterday in The Brattleboro Reformer.
The memo was written in September 1971 by Atomic Energy Commission staff member Dr. Stephen Hanauer. In it he expressed concern that similar acts of sabotage could take place in commercial nuclear reactors.
But Hanauer, now a senior staff member at the Nuclear Regulatory Commission, told the Reformer this week that although he is "paid to worry," he believed such sabotage would be much more difficult today.
The Reformer obtained the memo from Robert
Pollard, a nuclear engineer and former Nuclear Regulatory Commission staff
member, who is now an opponent of atomic power. The incident was at the
National Reactor Testing Station, near Idaho Falls, Idaho.
