as Senior Technical Assistant for Research and Development.
In 1964, Shaw left the Navy to join the Atomic Energy Commission as the director of the Division of Reactor Development and Technology.
In this role, he was responsible for overseeing all reactor research and development. Several reactor safety research programs were underway at the AEC. Among these was the Molten Salt Breeder Reactor (MSBR) program, which culminated in the
Molten Salt Reactor Experiment
The Molten-Salt Reactor Experiment (MSRE) was an experimental molten-salt reactor research reactor at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. This technology was researched through the 1960s, the reactor was constructed ...
(MSRE) at Oak Ridge. At the time, interest in extending the supply of nuclear fuel led to substantial research into breeder reactors. The competing designs included the MSBR and
Liquid Metal Fast Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be fueled with more-commonly available isotopes of uranium and thorium, such as uranium-238 and thorium-232, as opposed to the rare ...
. Shaw, with his Naval Reactors background, moved to stamp out research into reactor safety, and towards what he saw were the two proven reactor designs: the
light-water reactor
The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reacto ...
and the LMFBR.
In particular, in spite of the project's apparent successes, Shaw was directly responsible for the cancellation of the MSRE, and is credited with Weinberg's ouster from ORNL.
Shaw instead focused the AEC's resources into the development of LMFBRs, under the rationale that the technology was more mature than the MSBR. This would eventually lead to the failed
Clinch River Breeder Reactor Project
The Clinch River Breeder Reactor Project was a nuclear reactor project that aimed to build the USA's first large-scale demonstration breeder reactor plant. It was led by the U.S. Atomic Energy Commission (and a successor agency, the U.S. Energy ...

Personal life
In 1951, Shaw married Natalie Bisgyer Shaw.
The couple had three children: Eric Shaw, Andrea Shaw Reed, and Daniel Shaw. They had eight grandchildren.
Shaw was born into a Jewish family,
and was a member of
Temple Sinai in Chevy Chase until his death.
On November 24, 2001, Shaw died of pancreatic cancer at his home in Chevy Chase.
Legacy
At the time of his resignation, Shaw was criticized by several environmental groups, who alleged he had neglected safety questions in favor of reactor development programs.
Even beforehand, it was believed that he had essentially sabotaged the AEC's reactor safety programs for the sake of developing the LMFBR.
During the 21st century, many in the nuclear industry have criticized Shaw's actions, particularly in cutting funding for the MSBR program and for safety programs. Several writers have credited his actions with effectively killing off research into
