DOE Releases Manhattan District History and Oppenheimer Personnel Hearing Transcript via OSTI-Hosted OpenNet

by Rita Hohenbrink 09 Oct, 2014 in


The Department of Energy (DOE) recently completed two significant declassification efforts and has made the newly released documents publicly available on the OpenNet database, which DOE launched 20 years ago to improve public access to declassified documents.  The website is supported by the DOE Office of Classification and hosted by the Office of Scientific and Technical Information (OSTI) on a cost-reimbursable basis.

Over a 12-month period concluding in July 2014, DOE released to the public the Manhattan District History, a multi-volume classified history of the Manhattan Project.

100th DOE R&D Accomplishments Feature Page Celebration

by Linda McBrearty 08 Jul, 2013 in Products and Content
DOE R&D Accomplishments 100th Feature Page

DOE R&D Accomplishments is a unique website and database in the OSTI collection.  For over 14 years, special Feature pages have been methodically researched and useful information collected on scientists, discoveries, and historical events to include in this searchable resource.   It  is a rich source of DOE trivia unto itself. 

On June 12th, 2013, the 100th Feature Page was released on the website and it highlighted 2004 Nobel Prize Winner in Physics, David Gross.  Gross joins other featured DOE Nobel Laureates such as Glenn Seaborg, E. O. Lawrence, Melvin Calvin and Saul Perlmutter on this distinguished list.

The Manhattan Project -- Its Operations

by Mary Schorn 29 Nov, 2012 in Science Communications

Major operations for the Manhattan Engineer District (Manhattan Project) took place in remote site locations in the states of Tennessee, New Mexico, and Washington, with additional research being conducted in university laboratories at Chicago and Berkeley.

At the Metallurgical Laboratory in Chicago, Enrico Fermi's experiments at the CP-1 pile took place to determine the exact amount of neutron reduction needed for a safe and controlled sustained nuclear reaction.  A second pile (CP-2), with external cooling, was built at Argonne in order to move the continuing experiments away from populated areas.

The Manhattan Project -- Its Establishment

by Mary Schorn 03 Aug, 2012 in Science Communications
President Roosevelt Establishes the Manhattan Project

On August 13, 1942, the Manhattan Engineer District, whose name was based upon the geographical location of its headquarters, was established.  In September, the Army appointed Colonel Leslie R. Groves to head the effort.  Groves held that the exigencies of war required scientists to move from laboratory research to development and production in record time.  Though traditional scientific caution might be short-circuited in the process, there was no alternative if a bomb was to be built in time to be used in the current conflict (World War II).

Various isotope separation methods (uranium enrichment) to produce uranium-235 were being researched at this time.  One was gaseous diffusion being done at Columbia and another was the electromagnetic method being done at Berkeley under Ernest O. Lawrence.  Based upon the success of the electromagnetic method, the S-1 (The Office of Scientific Research and Development Section On Uranium) Executive Committee recommended building plants in Tennessee at Site X (now Oak Ridge).

The Manhattan Project -- Its Background

by Mary Schorn 12 Jul, 2012 in Science Communications

This year is the 70th anniversary of the establishment of the Manhattan Project, a predecessor of the U.S. Department of Energy.  In honor of its impacts on science and history, a 'Manhattan Project' series on this blog will revisit various aspects of its background, establishment, operations, and immediate and long-term influences. The first of the series is about the background of the Manhattan Project.

During the fall of 1939, President F. D. Roosevelt was made aware of the possibility that German scientists were racing to build an atomic bomb and he was warned that Hitler would be more than willing to resort to such a weapon.  As a result, Roosevelt set up the Advisory Committee on Uranium, consisting of both civilian and military representatives, to study the current state of research on uranium and to recommend an appropriate role for the federal government.  The result was limited military funding for isotope separation and the work on chain reactions by Enrico Fermi and Leo Szilard at Columbia University.

STIP Partnership Ensures DOE R&D Results Are Disseminated

by Sharon Jordan 16 Jun, 2011 in Science Communications
Sharon Jordan, OSTI Assistant Director, and John Kunze, California Digital Libra

Many posts could be written about the rich history of the Office of Scientific and Technical Information (OSTI), which dates back to 1945 when Colonel K. D. Nichols announced plans for a complete and authoritative scientific record of all research work performed by Manhattan District contractors.  However, I want to focus on a specific slice of that history, one that is going strong and is well represented across the DOE complex.  I’m referring to DOE’s Scientific and Technical Information Program (STIP, www.osti.gov/stip).

Technical Reports and Journal Articles

by Bob Marianelli 20 Aug, 2010 in Products and Content

Technical reports and journal articles are both used to report the results of research and development projects. There are differences between the two that are driven by the objectives of each form of reporting.

document excerpt

The primary objective of journal articles is to report results of experimental and/or theoretical scientific investigations to enhance the body of scientific knowledge. This is the primary way that (1) science advances and (2) the scientific community communicates among its members and practitioners. Typically, there are space limitations prescribed by the journal publisher that limit the length of journal articles usually to only a few pages. Journal articles are almost always subjected to a rigorous peer review process before they are accepted for publication.
