Reed Research Reactor: Portland ,Oregon


Reed Research Reactor

About the Reactor

The Reed Research Reactor was established in 1968 and is the only reactor operated primarily by undergraduates. This section details its history, uses, and capabilities.

Introduction

The Reed College Reactor Facility has been used for research and educational projects in the Portland area since its establishment in 1968. Cooperative programs between Reed and several public and private high schools, colleges, and universities in northwestern Oregon were established in 1970 through the Nuclear Science Consortium of the Willamette Valley. These programs have been an important part of the educational picture of the region.
THE REACTOR
glowThe Reed College Reactor is a TRIGA Mark I water-cooled, "swimming pool" reactor at the bottom of a 25-foot-deep tank. It uses 58 zirconium hydride/uranium hydride fuel elements in a circular grid array. The uranium fuel is enriched to 20 percent in uranium-235. The reactor is surrounded by a graphite ring which minimizes neutron leakage by reflecting neutrons back into the core. Most reactor components are clad with aluminum.
The reactor can operate at any power up to the license ceiling of 250 kW. This makes it possible to provide a defined neutron flux as required for the experiment. The power level is usually maintained for periods ranging from a few minutes up to eight hours. Continued or repeated operation over several days is possible for longer irradiations.

Experimenter Information

Much of the work performed at the Reed reactor is in collaboration with external research groups. If you are interested in using the Reed reactor for a project, this section is for you.

For incoming students

We are dependent on incoming freshmen who want to run the reactor. Without you we'd be shutdown in four years for lack of operators.
There are no prerequisites to taking the seminar. The orientation meeting is on Tuesday, September 6 at 7:30 pm in Psychology 105. Subsequent meetings are on Mondays. 
The seminar is in addition to your regular class load. The seminar meets two nights every week. On Monday's at 7:30 pm there is a group seminar in lecture/discussion format. On Wednesday there is a practical lab to apply the skills necessary to operate the reactor. The Wednesday lab is repeated on Thursday to keep the labs small and so you have a choice of nights. There are homework assignments and checkoffs requirements in addition to the class time and labs. The seminar runs September through the first week of December.
Sometime around Thanksgiving, 15 students are selected to continue the program in January to get ready for the NRC exam in May. We come back two weeks BEFORE classes start in the Spring for two weeks of maintenance and work. That will be on January 9, 2012. The seminar then starts again in the same format (Monday and Wednesday/Thursday) until the end of April. Then the NRC exams consist of a three hour written exam and a four hour operational exam. They will probably be during the week of April 30, 2012.
All this information will be publicized during orientation week and the first week of classes. If you somehow miss the notices, feel free to email or call after classes start.

Galen Winsor: Nuclear Scare Scam


Ben Williams (benwilliamslibrary.com) made this video with Galen Winsor in 1986. Galen Winsor is a nuclear physicist of renown who worked at, and helped design, nuclear power plants in Hanford, Washington; Oak Ridge, Tennessee; Morris, Illinois, San Jose, California; Wimington, New Jersey. Among his positions of expertise he was in charge of measuring and controlling the nuclear fuel inventory and storage. 

Galen Winsor has traveled and lectured all over America, spoken on national talk radio, and made several videos exposing the misunderstood issues of nuclear radiation. He shows that fear of radiation has been exaggerated to scare people ... so a few powerful people can maintain total control of the world's most valuable power resource.

Large diffusion cloud chamber with radon gas double-decaying!



awesome demonstration of a massive diffusion cloud chamber - with normal background radiation vs. americium 241 vs. the epic RADON 220 gas! just wow!

ps: yeah, i know i accidentally said "Radium 220" instead of "Radon 220" once - and that i said "half time" instead of "half life" a couple of times. sorry about that, i was just drained after that awesome day at the museum and thus, unable to concentrate properly.

Isolation of Uranium Yellowcake from Ore




In this video, uranium is concentrated from its ore through a series of precipitations, which eventually yields a form of yellowcake, uranyl peroxide. Please remember to take proper precautions when working with a radioactive heavy metal such as uranium and its salts. Gloves, eye protection, and a dust mask are necessary.

For processing, uranium ore is dissolved into hydrochloric acid, oxidized with bleach, precipitated with ammonia, filtered, leached with carbonate, filtered, neutralized with hydrochloric acid, precipitated with hydrogen peroxide, and filtered.

The uranium produced by this procedure could in no way be considered weapons-grade or enriched. The enrichment process requires millions of dollars in investment and is impossible for any entity short of a national government to produce. This uranium maintains the isotopic ratio found within the earth's crust and is actually less radioactive than the ore from which it was processed due to the absence of more radioactive decay products of uranium, such as radium, protactinium, and other unstable nuclei produced by the spontaneous fission of U238.

Though ore chemistry varies by locality, this process is generalized for any uranium on an acid-soluble matrix.
This process was inspired by and based off of:http://carlwillis.wordpress.com/2008/02/20/uranium-chemistry/
