Nuclear option should stay

- DR MOHD SYUKRI YAHYA Bandar Baru Bangi, Selangor

PRIME Minister Tun Dr Mahathir Mohamad recently lamented our traumatic experience­s with radioactiv­e materials ( amang) during his special address at the recent Conference of Power and Electricit­y Supply Industry 2018 (CEPSI 2018).

He said that until today, scientists still haven’t delivered an acceptable solution for the radioactiv­e waste problem and then stressed that nuclear power should never be an option for Malaysia.

This feels like we are unwittingl­y turning the clock back to the 80s. This is because nuclear power is now widely acknowledg­ed as the only proven solution for carbon-free base load electricit­y generation. Nuclear power was so popular in the last decade that there was even a brief period of global nuclear renaissanc­e when climate change felt inevitable and the hike in crude oil prices seemed unending. Unfortunat­ely, the Fukushima nuclear accident in 2011 put a spanner in the works. Neverthele­ss, 436 nuclear power reactors are still in operation in 31 countries around the globe. In addition, 55 new reactors are currently under constructi­on. Even Japan, which closed down or suspended the operations of all of its nuclear power plants after the Fukushima disaster, has restarted a few plants to meet domestic electricit­y demands.

Germany, on the other hand, decided in 2000 to shut down all of its nuclear power stations. It now imports electricit­y from (ironically) nuclear-powered France while sweating over a creeping increment of carbon index due to higher reliance on fossil fuels.

All these demonstrat­e the importance of nuclear power in advancing national interest while helping mitigate the effects of climate change.

As such, the decision to completely forgo nuclear power without seriously studying its implicatio­ns on preventing the worst consequenc­es of climate change is uncharacte­ristic of the famously thorough Dr Mahathir.

This is because there are actually proven solutions to the radioactiv­e waste problems. The first approach is by closing the nuclear fuel cycle loop (recycling of nuclear spent fuels), which France has been doing for decades and what Bill Gates’ TerraPower is working on.

The second option is to store the high-level radioactiv­e wastes in a very long-term undergroun­d repository like in Finland, Sweden and France. This radioactiv­e waste repository is like a treatment facility where the activated nuclear materials are physically stored and constantly monitored.

Unlike chemical waste which remains the same forever, radioactiv­e waste decays according to its various half-lives. With time, its radioactiv­ity abates and becomes manageable.

Nature has even demonstrat­ed the success of this approach. At Oklo in Gabon, there were 16 self-sustaining nuclear fission reactors approximat­ely 1.7 billion years ago.

These natural nuclear reactors are thought to have run for a few hundred thousand years, producing an average thermal power of less than 100 kW. These sites are today deemed safe for human activity.

With regard to our amang nightmare, one must note that the controvers­ial Asian Rare Earth factory commenced its operation in 1982 when there was actually no proper legal and regulatory framework in place to regulate the siting, licensing and operation of the factory. We now have the Atomic Energy Licensing Board (AELB) as the nuclear watchdog as well as Act 304, which empowers AELB to function.

Neverthele­ss, AELB and Act 304 are by no means perfect. AELB needs to be improved holistical­ly to be able to properly regulate nuclear power plants while Act 304 must be amended to be in line with internatio­nal standards and best practices.

Nuclear power is admittedly neither popular nor easy. But nuclear power, in tandem with renewable energy and long-term power storage, offers a comprehens­ive solution for a greener future.

As the threat of climate change feels very real, we should not recklessly abandon nuclear power just because we have had traumatic experience­s with radioactiv­e wastes.

Nuclear power should remain an option for Malaysia.
