744.0. "NASA and DOE sign Space Nuclear Power Agreement" by PRAGMA::GRIFFIN (Dave Griffin) Mon Jul 29 1991 10:05

RELEASE: 91-119 (7/26/91)

     NASA Administrator Richard H. Truly and Secretary of
Energy James D. Watkins today signed an interagency
agreement on cooperation in areas relating to space isotope
power.

     Today's agreement updates an earlier pact dating back
to 1965.  The present accord provides an "umbrella" set of
principles that delineates the authorities and
responsibilities of NASA and DOE on the research,
technology development, design, production, delivery,
spacecraft integration and launch support for radioisotope
power systems.  Supplemental agreements will be signed for
each specific NASA mission at the assistant secretary and
associate administrator level.

     NASA and DOE have cooperated extensively on space
missions since the beginning of the U.S. space program.
For example, DOE provided nuclear power sources
(radioisotope thermoelectric generators, or RTGs) for the
Apollo Lunar Surface Experiment Packages and the Viking
Mars landers.  RTGs use the natural decay of Pu-238 to
produce heat which is transformed into electrical power
through thermoelectric devices.  A typical modern RTG
produces about 300 watts of electrical power and will
operate unattended at this level for many years.  Some have
operated for more than 14 years.

     Deep space missions such as the Pioneers 10 and 11,
launched in 1972 and 1973, are still operating near the
edge of our solar system.  The Voyager spacecraft, launched
in 1977, is still operational due to its being powered by
RTGs.  The recently launched Galileo and Ulysses also used
RTGs.  A total of 17 NASA flights used nuclear power
systems -- all with an unparalleled safety record.

Subject: Russia will sell United States plutonium for space research

	MOSCOW (UPI) -- In the first deal of its kind, Russia is ready to
export to the United States a consignment of plutonium isotope for use
in space research, the Russian news agency Itar-tass reported Monday.

	The U.S. Department of Energy is reportedly negotiating to buy 88
pounds of radioactive plutonium-238 isotope from Russia's nuclear energy
industry for use in the U.S. space program.

	The deal marks a modest success for Russia's defense industry as it
trys to make a sometimes painful switch to peacetime production and
seeks new markets for its goods.

	Plutonium isotope radiates heat that can be easily transformed into
electricity, and is often used to power scientific apparatus in space
exploration. Plutonium-238 is not fissionable and cannot be used to make
nuclear weapons, unlike its slightly heavier cousin plutonium-239.

	``The isotope can be used in space equipment where a long-lasting and
reliable electricity supply is needed,'' said Yevgeny Mekerin, head of
the Russian Nuclear Energy Ministry's isotope department.

	Mekerin said the United States has its own plutonium-238 but the
Russian isotope is a better quality.

	Plutonium-238 is manufactured at military factories in Chelyabinsk, a
Urals city 1,192 miles east of Moscow once closed to outsiders when it
produced weapons-grade plutonium for the former Soviet Union's nuclear
missiles.

	``The enterprises started making plutonium-238 when military spending
was cut,'' Mekerin said. He said the isotopes are used in Russia as a source 
of electric current for cardiostimulators and for other medical purposes.

	The switch to manufacturing isotopes with no military application
shows how Russian defense factories, starved of state orders, are
converting to civilian production in an effort to survive the painful
shift to a market economy.

	Russia has had some success selling its hi-tech space equipment to
other countries. Recently, it sold the United States a nuclear reactor
for use in space, and several joint projects are in the pipeline.

	But attempts by the Nuclear Energy Ministry to market plutonium
isotopes abroad have been disappointing. With only very few countries engaged 
in space research, the demand for such isotopes is low, Mekerin said.

	The U.S. Energy Deparment contract, which should be ready in two to
three months, includes a pledge that the isotopes will only be used for
peaceful purposes, Mekerin said.
