X-energy receives federal tax credit for TRISO fuel facility
Advanced reactor company X-energy has been awarded $148.5 million in tax credits under the Inflation Reduction Act for construction of its TRISO-X fuel fabrication facility in Oak Ridge, Tenn.
The Everitt P. Blizard Memorial Scholarship was established by the Radiation Protection & Shielding Division in November of 1993 to recognize graduate students studying in the field of radiation protection & shielding.
The manner in which a particular corner of science develops is often deeply influenced by the right man appearing at the right moment in its history. For reactor radiation shielding, that man was Everitt Pinnell Blizard.
Everitt Pinnell Blizard (1916-1966) was born on September 30, 1916, in Ottawa, Canada. He received a bachelor’s degree in chemistry from Wesleyan University and a master’s degree in physics from Columbia University. Before completing his doctorate work, he was employed by the Navy in 1941. As a result of his contributions in such programs as the “CROSSROADS” atom bomb tests at Bikini, he was selected by Captain Hyman Rickover to participate in the nuclear submarine program and was sent to Oak Ridge, Tennessee, to attend the charter session of a nuclear training school. Although intended to be temporary, his stay in Oak Ridge continued until his death from leukemia in 1966.
“Bliz,” as he was better known, began with a small group of pioneers at Oak Ridge National Laboratory and developed a significant division of researchers addressing all aspects of radiation shielding, including experiments, analytical models, and nuclear data. Four major test facilities were constructed under his leadership, beginning with the “Core Hole” facility – a 2-ft-square hole in the shield of the original X-10 Graphite Reactor. Although immediately successful, the facility had significant limitations, and the group went on to develop more powerful and more flexible test facilities, including the Lid Tank Shielding Facility, the Bulk Shielding Facility, and the Tower Shielding Facility. This latter facility provided the international shielding community with abundant benchmark data over a span of nearly four decades. Blizard also recognized the importance of analytic methods and was instrumental in bringing theoretical physicists together to develop and apply new methods. His exploitation of the concept of a neutron removal cross-section had, perhaps, the widest impact on early methods development.
Beyond Bliz’s technical leadership, his humanistic interest and sensitivity toward others often led him into a role as international ambassador for reactor shielding. He was one of the scientific members of the U.S. Atoms for Peace Mission to the Far East in 1957 and participated in numerous other outreach missions. He also contributed substantially to many handbooks and encyclopedias, including the shielding portion of the Reactor Handbook and the Engineering Compendium on Radiation Shielding.
Because of this vision, his technical alertness, and his warm and inspiring personality, Blizard is rightly recognized as the “father of reactor shielding” and is credited with bringing the field of reactor radiation shielding from an empirical rule-of-thumb craft to a distinct discipline in nuclear science and technology.
As with many scientists of his day, he was a warm human being who inspired many young people to attain goals they never thought were possible. He had a knack for selecting the right individual for the job and giving them the guidance and trust they needed to succeed.
