# How large was one side of the original K-25 building?

## How large was one side of the original K-25 building?

The U-shaped K-25 building measured half a mile by 1,000 feet and is larger than the Pentagon. Construction began before completion of the design for the process.

What would K-25 produce?

K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs using the gaseous diffusion method.

What is K-25?

Pill with imprint K 25 is White & Blue Specks, Elliptical / Oval and has been identified as Phentermine Hydrochloride 37.5 mg. It is supplied by KVK Tech Inc.. Phentermine is used in the treatment of weight loss; obesity and belongs to the drug classes anorexiants, CNS stimulants.

### What did the Calutron girls do?

“Calutron Girls” were young women hired to work at Y-12 at Oak Ridge National Laboratory. Many were just out of high school, and were tasked with monitoring the Calutron, which was the machine that separated enriched uranium isotopes.

What mixture separation method was used at the S 50 plant?

The S-50 Plant used the liquid thermal diffusion method developed by Philip Abelson to enrich uranium. The theory behind investing in S-50 was that the enrichment process might work best if the three plants were used in a series.

Which physicist was the lead civilian scientist of the Manhattan Project?

physicist Robert Oppenheimer
From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs.

#### Is phentermine a narcotic?

Phentermine: an appetite-suppressant amphetamine classified as a narcotic in France.

How much weight can I lose with phentermine?

The expected average weight loss with phentermine use is 5% of your initial body weight. Yet, over 12 weeks, it can be as high as 10%. This equates to a weight loss of 10–20 pounds (4.5–9 kg) for a 200 pound (90.7 kg) person ( 8 ).

How did the Calutron Girls impact society?

Thousands of “Calutron Girls” helped build the atomic bombs of World War II—but were unaware of what they were doing. Female high school graduates were recruited for positions as “cubicle operators” at Y-12, and have been more recently referred to as “Calutron Girls.” Ruth Huddleston is third back on the left, seated.

## What happened in Oak Ridge TN?

On August 6 and August 9, 1945, the United States dropped atomic bombs on the cities of Hiroshima and Nagasaki in Japan. Soon after the first bomb dropped, the local newspaper in Oak Ridge, TN ran the banner headline, “Oak Ridge Attacks Japan”.

Who was responsible for the separation of uranium 235?

In fact, 27,000 years would have been required for a single spectrometer to separate 1 gram of uranium-235. Ernest O. Lawrence of the Radiation Lab at the University of California at Berkeley favored this method and converted his giant cyclotron to accomplish this form of separation more efficiently.

How is U 235 separated from U 238?

Thermal diffusion uses the transfer of heat across a thin liquid or gas to accomplish isotope separation. The process exploits the fact that the lighter 235U gas molecules will diffuse toward a hot surface, and the heavier 238U gas molecules will diffuse toward a cold surface.

### What was the purpose of the K-25 plant in Oak Ridge?

The K-25 Plant in Oak Ridge, TN housed the massive gaseous diffusion apparatus used to partially enrich uranium before it was sent to the nearby Y-12 Plant. “K-25” comes from Kellex Corporation, the contractor that designed and built the plant, and uranium-235, often shortened to “25.”.

Why was Oak Ridge not on the map?

Yet officially Oak Ridge did not exist during the war and could not be found on any map. What was going on there? Very few people knew at the time, even among the residents. The answer was that this was the starting block in a race against Adolf Hitler to build the atom bomb.

Why was Oak Ridge chosen as the site for the atom bomb?

Nonetheless, 59,000 acres of land along the Black Oak Ridge were chosen by General Leslie Groves as the site to construct a city in which to house some 30,000 plant workers and four key facilities in the plant itself. DOE-Oak Ridge, Flickr The graphite reactor at Oak Ridge Laboratory.

#### Why was Oak Ridge important to the Manhattan Project?

Their homes were about to become a key site of the Manhattan Project: the construction of the first atomic bomb. More specifically, the Oak Ridge site would create the enriched uranium used as fuel for the first atomic bombs.
