Richard Feynman on helping the Manhattan Project

Mojofreem says...

@TheHam: Did you watch the entire video? I'm not sure what you saw that made you think he was being smug. He described the elation that the Los Alamos team felt upon the detonation over Hiroshima, as it was viewed at the time from a very isolated detached perspective. Upon further thought about the real implications of it's effect he grew very depressed. There's nothing smug there.

I always wondered why to my mother that we couldn't just throw all the nuclear waste into a volcano like Kīlauea?? Could we? Have they!?
I think this is a good explanation. FROM INTERNET

Dumping all our nuclear waste in a volcano does seem like a neat solution for destroying the roughly 29,000 tons of spent uranium fuel rods stockpiled around the world. But there’s a critical standard that a volcano would have to meet to properly dispose of the stuff, explains Charlotte Rowe, a volcano geophysicist at Los Alamos National Laboratory. And that standard is heat. The lava would have to not only melt the fuel rods but also strip the uranium of its radioactivity. “Unfortunately,” Rowe says, “volcanoes just aren’t very hot.”

Lava in the hottest volcanoes tops out at around 2,400˚F. (These tend to be shield volcanoes, so named for their relatively flat, broad profile. The Hawaiian Islands continue to be formed by this type of volcano.) It takes temperatures that are tens of thousands of degrees hotter than that to split uranium’s atomic nuclei and alter its radioactivity to make it inert, Rowe says. What you need is a thermonuclear reaction, like an atomic bomb—not a great way to dispose of nuclear waste.

Volcanoes aren’t hot enough to melt the zirconium (melting point 3,371˚) that encases the fuel, let alone the fuel itself: The melting point of uranium oxide, the fuel used at most nuclear power plants, is 5,189˚. The liquid lava in a shield volcano pushes upward, so the rods probably wouldn’t even sink very deep, Rowe says. They wouldn’t sink at all in a stratovolcano, the most explosive type, exemplified by Washington’s Mount St. Helens. Instead, the waste would just sit on top of the volcano’s hard lava dome—at least until the pressure from upsurging magma became so great that the dome cracked and the volcano erupted. And that’s the real problem.

A regular lava flow is hazardous enough, but the lava pouring out of a volcano used as a nuclear storage facility would be extremely radioactive. Eventually it would harden, turning that mountain’s slopes into a nuclear wasteland for decades to come. And the danger would extend much farther. “All volcanoes do is spew stuff upward,” Rowe says. “During a big eruption, ash and gas can shoot six miles into the air and afterward circle the globe several times. We’d all be in serious trouble.”

I am not an atomic playboy (29 sec)

rougy says...

He...he was an asshole.

He had no fucking clue what was going on.

They had no idea, those Los Alamos retards.

They still don't.

Well, they're a little better I suppose.

A teensy tiny bit.

Steven Jones Pipes In About 9/11

Ryjkyj says...

>> ^MycroftHomlz:
At a March Meeting special session on Cold Fusion, the consensus was that Jones had either grossly misrepresented his data, made egregious errors in his data analysis or committed academic fraud. Many other researchers, including myself think the later.
Fraud may have been a strong word, but I stand by it.

http://en.wikipedia.org/wiki/Muon-catalyzed_fusion


The first article you posted is about the furor caused by Dr.Fleischmann and Dr. Pons, not Steven Jones.

"Some of the new experiments also sought to reproduce the less contentious findings on cold fusion reported independently by Dr. Steven E. Jones and his colleagues at Brigham Young University in Utah. Dr. Jones, who used a device similar to the one in the Pons-Fleischmann experiment, did not claim that any useful energy was produced. But he did report that slightly more neutrons were detected while the cell was operating than could be expected from normal sources. The result suggests at least the possibility of fusion, he said, although it is not likely to be useful as an energy source.

Physicists who have investigated Dr. Jones's report have been fairly restrained in their criticism, acknowledging that Dr. Jones is a careful scientist. But from the outset they have expressed profound skepticism of claims by Dr. Fleischmann and Dr. Pons."

The second article, from wikipedia, mentions him once:

"Indeed, the team led by Steven E. Jones achieved 150 d-t fusions per muon (average) at the Los Alamos Meson Physics Facility.[31] Unfortunately, 200 (or 250 or even 333) muon-catalyzed d-t fusions per muon are still not quite enough even to reach "break-even," where as much thermal energy is generated (or output) as the electrical energy that was used up (or input) to make the muon in the first place."

Robert Oppenheimer's thoughts after first atomic explosion

guessandcheck says...

This video is strangely moving. You can tell that Oppenheimer's mind was probably never at ease again. There's something so painful in his expression that I've decided to make a new playlist: The Human Condition

Also, for a little more insight, although possibly slightly fictionalized:

The Official MycroftHolmz Roast! (Parody Talk Post)

rougy says...

"I have a better one, which all have apparently failed to notice. I misspelled my name(Holmz not Homlz) when I first joined videosift... for a week I couldn't log in and I had no idea way."

So you're a living tribute to Johnny Wadd and you didn't even know it.

Don't knock physicists - they're some of the best damned floor sweepers at Los Alamos.

When they say "Hey, buddy, wanna computer?" You know you're getting good, quality, government surplus.

(better late than never - I would have posted sooner if they all weren't out to get me)

Debunking the Thermite Theory: 911 Consipiracy

rougy says...

Sure, Lurch.

9/11 happened just exactly like Bush said it did, and he would never stoop to having people silence dissent. He's such an honest man, and he would never lie to get what he wants.

Wow – you are naïve.

Remember the Los Alamos scientist who publically claimed the building's shouldn't have fallen like they did? Remember how he was forced to recant his statement only days later?

And:

"Jeffrey, 45, was nominated by President Bush on May 25, 2005, to succeed Arden Bement, who was appointed director of the National Science Foundation in November of last year. NIST Deputy Director Hratch Semerjian has served as acting director in the interim."

This commercial will blow you away...

jimnms says...

"btw i would rather have one nuclear power station than seven gajillion acres of inefficient turbines. They are not made of recycled paper, you know?"...

"If you like progress, and you think a fucking windmill is progress, then you're mental."

You're comparing plastics with nuclear waste and you're calling me mental? At least plastic can be recycled. Nuclear power plants aren't made of recycled paper either, and they must continually be re-fueled every 18 months. Do you think they that fuel grows on trees? Wind turbines require no fuel, and need very little maintenance.

Progress is building more safe, renewable resources for power such as wind, hydro and solar power plants, not building more nuke plants.

I know all about Chernobyl and nuclear reactors, I used to work at one. I know the designs are different, my point is that it only takes one accident and the effects on the environment and life lasts for generations. Do you realize how many nuclear accidents there have been, besides the two major ones (TMI and Chernobyl)? There's more than just accidents at nuclear plants, accidents occur during the manufacturing, transport, storage, and disposal of the nuclear fuel. They may not be as big as Chernobyl, but the damage to the environment has been done, and the "pollution" will be around longer than you or I.

Here's a list of just some of the nuclear accidents in just the US alone:

July 1959 - Boeing-Rocketdyne Nuclear Facility in Ventura County, California, A clogged coolant channel resulted in a 30% reactor core meltdown, which led to the release of the third greatest amount of radioactive iodine-131 in nuclear history.

July 1956 - Sylvania Electric Products' Metallurgy Atomic Research Center, Bayside, Queens, New York, nine people were injured when two explosions destroyed a portion of the facility.

December 1958 - Los Alamos Scientific Laboratory in New Mexico. A nuclear criticality accident killed 1 operator.

1959 - Santa Susana Field Laboratory in Simi Valley Hills, California. A partial sodium reactor meltdown occurred.

January 1961 - National Reactor Testing Station in Arco, Idaho. A reactor explosion, killed 3 technicians, and released radiation. The men were so heavily exposed to radiation that their hands had to be buried separately with other radioactive waste, and their bodies were buried in lead coffins.

October 1966 - Detroit Edison's Enrico Fermi I demonstration breeder reactor near Detroit, Michigan. A sodium cooling system malfunction caused a partial core meltdown.

November 1971 - Northern States Power Company's reactor in Monticello, Minnesota. The water storage space filled to capacity and spilled over, dumping about 50,000 gallons of radioactive waste water into the Mississippi River.

1972 - The West Valley, NY fuel reprocessing plant was closed after 6 years in operation, leaving 600,000 gallons of high-level wastes buried in leaking tanks. The site caused measurable contamination of Lakes Ontario and Erie.

March 1972 - A routine check in a nuclear power plant in Alaska indicated abnormal radioactivity in the building's water system. Radioactivity was confirmed in the plant drinking fountain. Apparently there was an inappropriate cross-connection between a 3,000 gallon radioactive tank and the water system.

December 1972 - A plutonium fabrication plant in Pauling, New York. An undetermined amount of radioactive plutonium was scattered inside and outside the plant, after a major fire and two explosions occurred resulting in its permanent shutdown.

May 1974 - The Atomic Energy Commission reported that 861 "abnormal events" had occurred in 1973 in the nation's 42 operative nuclear power plants. Twelve involved the release of radioactivity "above permissible levels."

March 1975 - Browns Ferry reactor, Decatur, Alabama. A fire burned out electrical controls, lowering the cooling water to dangerous levels, before the plant could be shut down.

1979 - The Critical Mass Energy Project tabulated 122 accidents involving the transport of nuclear material in 1979, 17 involving radioactive contamination.

March 1979 - Three Mile Island nuclear plant near Middletown, Pennsylvania. After cooling water was lost, the top portion of the reactor's 150-ton core collapsed and melted. Contaminated coolant water escaped into a nearby building, releasing radioactive gasses. A study by Dr. Ernest J. Sternglass, professor of radiation physics at the University of Pittsburgh, showed that the accident led to a minimum of 430 infant deaths.

July 1979 - Church Rock, New Mexico. A dam holding radioactive uranium mill tailings broke, sending an estimated 100 million gallons of radioactive liquids and 1,100 tons of solid wastes downstream.

August 1979 - A nuclear fuel plant near Erwin, Tennessee. Highly enriched uranium was released. About 1,000 people were contaminated with up to 5 times as much radiation as would normally be received in a year. Between 1968 and 1983 the plant "lost" 234 pounds of highly enriched uranium, forcing the plant to be closed six times during that period.

January 1980 - Lawrence Livermore National Laboratory (where large amounts of nuclear material are kept). An earthquake caused caused a tritium leak.

September 1980 - Two canisters containing radioactive materials fell off a truck on New Jersey's Route 17. The driver, en route from Pennsylvania to Toronto, did not notice the missing cargo until he reached Albany, New York.

1981 - The Critical Mass Energy Project of Public Citizen, Inc. reported that there were 4,060 mishaps and 140 serious events at nuclear power plants in 1981.

February 11, 1981 - Tennessee Valley Authority's Sequoyah I plant in Tennessee, 110,000 gallons of radioactive coolant sprayed into the containment building, which led to the contamination of eight men.

July 1981 - Nine Mile Point's Unit 1 in New York state. A flood of radioactive wastewater in the sub-basement caused approximately 150 55-gallon drums of high-level waste to overturn, some of which released their highly radioactive contents. Some 50,000 gallons of radioactive water were subsequently dumped into Lake Ontario to make room for the cleanup.

January 25, 1982 - Rochester Gas & Electric Company's Ginna plant near Rochester, New York. Fifteen thousand gallons of radioactive coolant spilled onto the plant floor, and radioactive steam escaped into the air after a steam generator pipe broke.

January 1983 - Browns Ferry power plant, Athens, Alabama. About 208,000 gallons of water with radioactive contamination was accidentally dumped into the Tennesee River.

February 1983 - Salem 1 reactor in New Jersey. A catastrophe was averted by just 90 seconds when the plant was shut down manually, following the failure of automatic shutdown systems. The same automatic systems had failed to respond in an incident three days before. Other problems plagued this plant as well, such as a 3,000 gallon leak of radioactive water in June 1981 at the Salem 2 reactor, a 23,000 gallon leak of radioactive water (which splashed onto 16 workers) in February 1982, and radioactive gas leaks in March 1981 and September 1982 from Salem 1.

December 1984 - The Fernald Uranium Plant, a 1,050-acre uranium fuel production complex 20 miles northwest of Cincinnati, Ohio. The Department of Energy disclosed that excessive amounts of radioactive materials had been released through ventilating systems. Subsequent reports revealed that 230 tons of radioactive material had leaked into the Greater Miami River valley during the previous thirty years, 39 tons of uranium dust had been released into the atmosphere, 83 tons had been discharged into surface water, and 5,500 tons of radioactive and other hazardous substances had been released into pits and swamps where they seeped into the groundwater. In addition, 337 tons of uranium hexafluoride was found to be missing, its whereabouts completely unknown. The plant was not permanently shut down until 1989.

1986 - A truck carrying radioactive material went off a bridge on Route 84 in Idaho, and dumped part of its cargo in the Snake River. Officials reported the release of radioactivity.

6 January 1986 - The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma. A container of highly toxic gas exploded, causing one worker to die (when his lungs were destroyed) and 130 others to seek medical treatment.

December 1986 - Surry Unit 2 facility in Virginia. A feedwater pipe ruptured, causing 8 workers to be scalded by a release of hot water and steam. Four of the workers later died from their injuries. In addition, water from the sprinkler systems caused a malfunction of the security system, preventing personnel from entering the facility.

1988 - It was reported that there were 2,810 accidents in U.S. commercial nuclear power plants in 1987.

November 1992 - The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma closed after repeated citations by the Government for violations of nuclear safety and environmental rules. It's record during 22 years of operation included an accident in 1986 that killed one worker and injured dozens of others and the contamination of the Arkansas River and groundwater. The Sequoyah Fuels plant, one of two privately-owned American factories that fabricated fuel rods, had been shut down a week before by the Nuclear Regulatory Commission when an accident resulted in the release of toxic gas. Thirty-four people sought medical attention as a result of the accident. The plant had also been shut down the year before when unusually high concentrations of uranium were detected in water in a nearby construction pit. A Government investigation revealed that the company had known for years that uranium was leaking into the ground at levels 35,000 times higher than Federal law allows.

March 1994 - A nuclear research facility on Long Island, New York. A fire resulted in the nuclear contamination of three fire fighters, three reactor operators, and one technician. Measurable amounts of radioactive substances were released into the immediate environment.

February 2000 - Indian Point II power plant in New York vented radioactive steam when a an aging steam generator ruptured.

March 2002 - Davis-Besse nuclear plant in Ohio. Workers discovered a foot-long cavity eaten into the reactor vessel head. Borated water had corroded the metal to a 3/16 inch stainless steel liner which held back over 80,000 gallons of highly pressurized radioactive water.

Do you honestly think that more of this is worth not having to look at a field of wind turbines (they're not windmills btw, yes I get the refrence )? As far as I know, wind turbines have not killed anyone or released toxic and radioactive materials into the environment.
