Nuclear power generation for any ‘new-entry’ country such as
Kenya is a long process which must be walked to ensure that the country
has developed sufficient knowledge, laws, regulations, institutions and
systems to guarantee a safe nuclear power sector.
For
nearly 10 years, Kenya has undertaken a step-by-step capacity building
process to meet safety and governance standards set by international
atomic certifying agencies.
Recently, the Kenya Nuclear Electricity Board indicated that the country is targeting a 1,000-megawatt nuclear plant by 2027.
Nuclear
power is a clean renewable source of energy with a minimal carbon
footprint. It provides a very reliable and stable base-load generation
round-the-clock and throughout the year which is essential for balancing
a fluctuating grid power demand and supply.
Although the initial capital costs for nuclear plants are quite high, this is balanced by lower operating costs.
Nuclear
fuel is also immune from global price volatility, and replenishments
are at long intervals. Freshwater is the other key input needed for
steam generation.
Site selection for nuclear plants is
mainly advised by water supply reliability and absence of tectonic
activities such as earthquakes
However, it is the perceived safety concerns and fears that make
nuclear power generation a difficult ‘sell’ and a tough political path
to navigate, especially in developing countries. In the absence of
public awareness and education, perceptions persist of potential nuclear
leakages whose impacts would be difficult and expensive to mitigate.
These fears are informed by real-life examples of such disasters around
the world.
There is also the peripheral relationship
between nuclear power generation and technological capacity to make
nuclear weapons for either offensive or defensive purposes.
For this reason, global protocols are required to give assurances that the nuclear plant will solely be for power generation.
Venturing
into nuclear power is essentially a political decision by the
government which must re-assure Kenyans on the state of readiness by the
country to safely embark on its generation.
In
addition to safety, the government will also need to ascertain that the
generation is in harmony with the policies for an optimum national
generation mix which includes the least-cost criterion, national energy
security, grid supply/demand stability, cost of transmission, and
climate change impacts.
Nuclear generation, like all
the other sectors — gas turbines, oil thermal, coal, geothermal, hydro,
wind and solar, among others — has its own club of global investors and
lobbies.
And all these sectors compete for the ‘ear’
of government energy planners. That is why each sector, including
nuclear, will need to sufficiently justify its place in our national
energy mix.
Based on the yardsticks listed above,
geothermal is currently considered a high scorer on the generation-mix
priority list. Nuclear power will, therefore, need to exceed geothermal
in technical, economic and environmental attributes so as to earn a
priority rating.
My opinion is that Kenya should not be
‘scared’ of taking an informed risk on nuclear generation once
certified for compliance by global agencies.
Over
the past ten years, technological advances have significantly de-risked
nuclear plants especially from safety viewpoints, while new designs
continue to reduce project costs. We, therefore, need to be opening
minded and give nuclear generation a fair chance.
Across
the globe, many nuclear projects continue to be committed.
public-private partnership investors are ready with funding for suitable
nuclear projects provided that feed-in tariffs are suitable and other
regulatory and country risks are manageable.
Among our peers, South Africa is seeking to increase its nuclear power generation, while Nigeria plans to embark on it.
The
energy planners should in the meantime undertake a serious national
electricity demands study. Five years ago, an overstated ‘5000-megawatt’
demand misinformed decisions on quantity and types of generation needed
and this may have led to crowding-out of priority generation sectors
while creating surplus capacity which is paid for by consumers.
Kenya is ‘spoilt’ for choice with so many alternative energy generation options which now include nuclear power.
All
these will need to compete fairly on technical, economic and
environmental evaluations. The driving objectives should be cost,
quality and security of supply.
