ABU Zaria Creates Waves in Use of Nuclear
Technology
Nuclear technology is a technology that permits
the exploitation of nuclear energy. This is an energy held in the nucleus of an
atom. The energy is obtained through two types of reactions - fission and fusion;
Nuclear reaction. Large volume of energy can be obtained from Nuclear reaction.
Example, through fission, one million times more energy per atom than fossil
fuel can be obtained per the same atom. No doubt discussion on this type of technology
is a complex technical process beyond the scope of newspaper column. However, it
is important to understand this technology and its potential for usefulness and
destruction to mankind and environment. The technology was first developed in
the 1940s during the Second World War.
Historically, it can be recalled that the
development and use of atomic bomb, which is one form of the nuclear technology
in 1945 ended the World War II. United States of America used the atomic bomb
twice on towns of Hiroshima and Nagasaki, Japan, which caused colossal and
instant destruction of lives and properties. USA developed two types of atomic
bombs; “little boy”, a uranium-based bomb and “fat man”, which was a
plutonium-based weapon. The World War II was almost ending as at April 1945 in
Europe but fierce fighting continued in the Pacific between Japanese forces and
USA forces. In late July, the then President of USA, Harry Truman called for Japan’s
surrender with the “Potsdam Declaration”. The declaration warned of “prompt and
utter destruction” to Japan, if it fails to surrender. On August 6, 1945, the
first atomic bomb “little boy” was dropped on Japanese city of Hiroshima from a
B-29 bomber plane called the “Enola Gay”. The “Little Boy” exploded with about
13 kilotons of force, leveling eight square kilometers of the city thereby
killing 80,000 people instantly. Tens of thousands more died later due to
exposure of radiation. Three days after the calamitous destruction, still, there
was no immediate surrender; the second atomic bomb “fat man” was dropped on the
city on Nagasaki that similarly killed an estimated number of 40,000 people by
the impact of the bomb. That made Japan to surrender and abrupt end of the
Second World War.
The
dreadful and mammoth impact of nuclear technology as weapon of mass destruction
in the history of humanity has united the world against its use. However,
acquisition of nuclear technology by countries became a symbol of military
prowess and shows of muscle. Soon, several countries acquired nuclear weapons. Within
first few decades after using atomic bombs, USA and USSR stockpiled tens of
thousands of nuclear warheads that initiated the so-called “Cold War”. Few
countries such as Great Britain, France, and China developed nuclear weapons
during this cold war era. The world became a fearful planet to live; it was
surrounded by uncertainty and anxiety. People were almost living by the day.
The concern in the Cold war era created an
antinuclear movement in 1961. It was a social movement created out of necessity
at the height of the Cold War. During the era, Women groups staged Peaceful demonstrations
on November 1, 1961. An estimated number of 50,000 women marched in 60 cities
in the United States demonstrated against nuclear weapons massively acquired by
the developed countries. The antinuclear movement captured international
attention again in the 1970s and 1980s with high profile protests against nuclear
reactors after the Three Mile Island accident—a nuclear meltdown at a
Pennsylvania power plant in 1979. The most fearful aspect of nuclear technology
as weapon of mass destruction is ‘once detonated, the impact of the weapon has
no respect of spatial boundary of a country nor has it temporal limitation on
the living things’. Neighborhoods of the target are likely to be affected and
similarly people in the affected area will continue to suffer radiation
exposure from generation to generation.
The global protests by antinuclear demonstrators
forced the world to initiate Nuclear Non-Proliferation Treaty (NPT). USA and
USSR took the lead in negotiating an international agreement to halt the
further spread of nuclear weapons in 1968. The Treaty on the Non-Proliferation
of Nuclear Weapons (also called the Non-Proliferation Treaty or NPT) went into
effect in 1970. It separated the world’s countries into two groups—nuclear
weapons states and non-nuclear weapons states. Nuclear weapons states included
the five countries that were known to possess nuclear weapons at the time—the
United States, the U.S.S.R., Great Britain, France and China. These five
countries agreed not to use nuclear weapons or help non-nuclear states acquire
nuclear weapons. They also agreed to gradually reduce their stockpiles of
nuclear weapons with the eventual goal of total disarmament. Non-nuclear
weapons states agreed not to acquire or develop nuclear weapons. However,
nuclear technology is not only for weaponry, it is also useful as source of
energy for national development
As early as in the 1950s, attention was turned
to the peaceful use of nuclear technology, using it to generate power. In the
last three decades, nuclear power plants have been operational in more than 30
countries worldwide. In fact, through regional transmission grids, many more
countries depend in part on nuclear-generated power; example, Italy and Denmark
receive power supplies of 10% of their electricity from imported nuclear power.
Today, nuclear technology is used for studies in neutron physics, agricultural
sciences, mineral exploration and similar other things. This civilian use of
nuclear technology for national development is the context at which Ahmadu
Bello University (ABU) Zaria is creating waves in the last two decades.
ABU Zaria through its Center for Energy
Research and Training (CERT) has been training and producing competent nuclear
scientists using the only nation’s Miniature Neutron Source Reactors (MNSR)
located at the university. The recent conversion of highly enriched uranium
(HEU) nuclear reactor to fuel containing low-enriched uranium (LEU) became the
latest in this wave creation. The feat is certainly the pinnacle to ensure that
the Nigerian only nuclear technology is used for peaceful nation building. It
is a practical demonstration of Nigeria’s interest in joining the race for the
peaceful, safe and secure uses of nuclear technology. The advent of
international terrorist groups across the globe makes it imperative to distant nuclear
technology from accessibility and use by these inhuman elements. The emergence
of Boko Haram with their limited usage of improvised explosive devices (IEDs)
in their terrorist acts underscores the importance of the university’s singular
achievement. How was the conversion from highly enriched uranium to low
enriched uranium achieved? Was the conversion necessary? Before then, it is
important to provide brief on the roles of CERT in the development of nuclear physics
in the country.
CERT
was established as a Centre of Excellence in Nuclear Science and Technology in
1986 under statute 29 of the Ahmadu Bello University Laws. The nuclear reactor
was installed at the Centre in 1997, making the country the 6th African nation
with nuclear technology. The five other countries are South Africa, Ghana,
Egypt, Morocco and Democratic Republic of Congo, to acquire a “classified
nuclear facility”, licensed by the world’s nuclear development ombudsman, the
IAEA. Thus, the Centre is the only country’s IAEA’s approved classified nuclear
facility. It occupies a 32 hectares of land with five departments: Nuclear
Science and Technology, Materials Science and Development, Engineering and
Instrumentation Design, Health Physics and radio bi-physics and Reactor
Engineering. The center started as a nuclear program of Ahmadu Bello
University, Zaria as far back as in 1977. The program was transformed to a unit
of the university in 1986. It was established basically to carry out basic and
applied research in nuclear science and technology and also to train Nigerians
on energy matters and nuclear science and technology. The nuclear facility
presently has over 150 personnel comprising nuclear research staff, technical
staff and supporting staff as recommended by IAEA international security
safeguard. The center has trained and sent several Nigerians to various parts
of the world over the years. It has also acquired several research equipment
and facilities in nuclear science and technology. Some of these facilities
include the only research reactor in the country and a neutron generator. It
also has the only licensed radioactive waste management facility in the country
and various analytical and radiation management facilities for various
applications. (To be continued next
