HTRs will not help establish nuclear power in Jordan

May 10,2018 - Last updated at May 10,2018

Chairman of Jordan Atomic Energy Commission (JAEC), Khaled Toukan, has announced that the organisation is in “serious and advanced” talks with China National Nuclear Corporation (CNNC) to build a 220 megawatt High Temperature Gas-Cooled Reactor (HTR) in the Kingdom. Viewed in light of earlier announcements by JAEC and its failure to realise any of its proposed plans since 2007, this pronouncement suggests that the Kingdom is downsizing its nuclear plans in a desperate bid to keep alive the possibility of building a nuclear plant in the country. But this effort is as misguided as prior ones and the best option is to stop investing any more effort, or money, into developing nuclear power.

Perhaps the most important earlier announcement worth recalling is from three years ago, when, amid much fanfare, Jordan signed an inter-governmental agreement with Russia to build two 1,000-megawatt reactors, at a total cost of $10 billion. The two reactors were “expected to be operational by 2022”. Reports suggested that Russia was to finance 50.1 per cent of the project and Jordan would find financing for the other half. But Jordan struggled to come up with its share.

Although there has been no official announcement to that effect, the project is likely dead. This is presumably why there is now talk of a smaller reactor.

The shift to smaller reactors could make the job of obtaining financing for the project easier because the total cost is lower. According to JAEC, the agreement for the HTR is expected to be worth $1 billion. The problem, though, is that it will also produce much less electricity. The reason that existing power reactors generally are much larger in terms of electricity generation capacity than their early prototypes is that small reactors are generally more expensive on a per unit basis and thus the electricity they produce is also costlier than electricity from larger reactors. 

The former factor can be deduced from the $1 billion price tag for 220 megawatts of power output. This implies a per unit cost of nearly $5,000 per kilowatt; even the most highly priced European Pressurised Reactor being constructed in Taishan in China is reported to cost only around $3,600 per kilowatt.

Now compare these to solar photovoltaic (PV) technology. The most recent solar PV project in Jordan is $150 million for 105 MW, or around $1,400 per kilowatt. PV costs are rapidly declining, and by the time any nuclear reactor can start generating electricity, solar costs will be even lower. In other words, Jordan will spend several times as much for each unit of electricity generation capacity by investing in a HTR.

That the electricity produced by HTRs will be expensive is also seen in China. Back in 2012, as China began constructing the first HTR in Shandong province, there were plans for eventually constructing further 18 units of the same type at the same site. But that is no longer the case and the promoters of the HTR now propose to construct a larger 600 MW design. 

Whether that happens or not remains to be seen, but the main motivation to switch to this larger design is “to improve project economics”. It has been reported in the trade journal Nuclear Intelligence Weekly that the cost of generating electricity at the HTR will be nearly 40 per cent higher than the corresponding cost at the modern light water reactors which China is also constructing. Fabricating the fuel for these reactors, in the shape of small spheres with multiple covering layers to prevent the escape of radioactivity, is also an expensive process and will drive up the cost of generating electricity at HTRs.

Mr Toukan has also promoted the HTR by terming it an “inherently safe reactor”. This is misleading. High temperature reactors can undergo severe accidents and release radioactive materials, primarily as a result of air or water coming into the system.

Operational experience with high temperature reactors that have been constructed in the United States and Germany have been disappointing, with reactors being prone to a variety of failures and being shut down ahead of targeted lifetimes; in turn, the shorter lifetime for such reactors will increase the cost of produced electricity.

To summarise, nuclear power remains a costly and risky solution, and a move to small reactors will not eliminate the problems with the technology. In fact, it will make them worse in some ways. The most economic way forward to address Jordan’s energy and water demands is for a larger scale expansion of renewables, especially photovoltaics, supplemented with natural gas or storage technologies to deal with their intermittency.

Nuclear power can provide safe, clean, reliable power for decades, but only if people have the vision and perseverance to build them.

This writing by M. V. Ramana is full of misinformation. The Russian VVER-1000 is a quality and proven nuclear reactor.

UAE started in 2012 and their first unit is about to be commissioned. Anyone who supports the Jordan nuclear Project is covering up on failures for 12 years and wasting 250 million Dollars that has to be taken to court.

The cancellation of the larger nuclear reactors (VVERs) and shift to the Small Modular Reactor (SMR) category is not new. The JAEC already announced that Phase II of nuclear deployment would be SMRs and even implied that SMRs were the preferred technical solution for Jordan but (lack of availability at the time the VVERs were selected) prompted the decision.

However, the decision on the HTR is a little too premature, considering how there are many SMR technologies out there and a formal evaluation and tender process is required first to examine all technologies.

I said it before and I say it again, this project has been mismanaged from day one. It's been managed by a group of incompetentant individuals that have no practical experience and easy target for the outside consulting firms. Non of had ever served in an operating nuclear plant

this project is not transparent and public has to be informed. why did the nuclear electricity company spended last year jd 45 million on 5 studies that were not published but all was secrete?

It is very insulting to each Jordanian that after 12 years of high salaries Mr Toukan has refrained from publishing a feasibility study for this source of energy that 90% of westren countries have dumped....!!

This article is one-sided. While PV and CST have huge potential for water desalination and to a limited extent electricity generation, nuclear remains the most viable and environmentally friendly method of electricity production, and at least as save as the alternatives. See the recent article published by Clack et al, in response to the errors in Jacobson's studies.

We don’t want nuclear reactors polluting our air under any curcumstance.

We don’t want nuclear power, only small political groups do. They’re too dangerous and expensive to maintain and operate, and will negatively affect the social homeostasis we have between our countries, and we want to keep trade ties open. We’re open to green energy bids over nuclear ones though. If they inquire about nuclear reactors or bids, just say you’re not open to exporting reactors.
