38th Tritium Focus Group Meeting: Tours

As part of your participation in the 38th Tritium Focus Group Meeting you may have the opportunity to participate in two separate tours. 
 
First, all attendees may have the opportunity to tour the Hanford B-Reactor based on tour requests.  Secondly, a Radiochemical Processing Laboratory (RPL) Tour will be available to those who are eligible to tour Limited Access (LA) areas.  No Foreign Nationals are allowed to participate without prior additional approvals which may or may not be approved.  Please select the tour check box on the registration page to sign up for either tour. A member of the meeting logistics team will contact all individuals who sign up in order to facilitate the badging process.
 
About the two tours:
 
B Reactor National Historic Landmark
The B Reactor National Historic Landmark at the Hanford Site in Washington state was the world’s first full-scale plutonium production reactor. Created as part of the top secret Manhattan Project during World War II, B Reactor produced plutonium used in the Trinity Test, as well as for the atomic bomb dropped on Nagasaki, Japan, to end World War II. The reactor was designed and built by the DuPont company based on experimental designs tested by Dr. Enrico Fermi at the University of Chicago and tests from the X-10 Graphite Reactor at Oak Ridge, TN. B Reactor was graphite moderated and water cooled. It consisted of a 28 by 36-foot, 1,200-ton graphite pile, penetrated through its entire length horizontally by 2,004 aluminum process tubes containing uranium fuel slugs. Cooling water from the nearby Columbia River was pumped through the aluminum tubes around the uranium slugs. This design allowed the reactor to produce plutonium-239 by irradiating naturally occurring uranium with neutrons.
 
Radiochemical Processing Laboratory
The Radiochemical Processing Laboratory (RPL/325 Building) is a Category 2 Nuclear Facility that houses PNNL’s hot cell facilities along with a variety of experimental capabilities relevant to post-irradiation examination on nuclear fuel and high-activity structural materials.  The tour will provide visitors the opportunity to see the High Level Radiological Facility containing three large hot cells used for cask receipt and initial size reduction, the Shielded Analytical Laboratory containing six intermediate hot cells used for precision size reduction and physical property measurements, and four modular hot cells used for thermal and mechanical properties testing.  The tour will also provide visitors a view of the RPL microscopy laboratories including the FIB/SEM, as well as a variety of other analytical laboratories.
