Phew, we will still have a controllable solution that produces little GHG, in addition to renewable energies.

Our EPR plants must still last 10 years maximum (see less) for the oldest (a large part of the park built in the years 70-80), it is urgent!

There is a downside to nuclear reasoning: as private non-subsidized solar costs less than the kWh cdiscount, people are going to equip themselves with self-consumption.
The non-subsidized corporate PV tariff reaches the level of the historical tariff for consumers in the 36 KVA - 500 KVA range. And so we will see companies and shopping centers covering their roofs and parking lots with PV.
Suddenly, the nuclear load factor will drop, and therefore the cost per kWh, which depends primarily on the load factor, will increase.
The next step is storage ... with new generation LFPs, we are currently under 100 € per kWh at 3500+ cycles.
By taking the minimum of 3500 cycles, that makes a storage cost excluding converters at 28 € per MWh (we are almost 200 € per MWh for individuals).

We know what follows: individuals and companies will equip themselves with PV + storage, the price of network kWh will increase and fuel this cycle.

We will end up with a few low-tech gas power stations that will run less than 1000 hours per year and billing in the 300 + € per MWh per hour or the centralized network will be called upon. EDF's current business model is dead. It's inevitable. The business model of centralized power generation is also financially dead.

I just take the example of a private individual who places himself PV and his storage system on the ground:
- 10 kWp of PV -> 3000 €
- supports and inverters: 2000 €
- 10 kWh useful of new generation LFP batteries: 1300 € VAT, customs and shipping included
Let's assume that 50% of production is lost (with batteries, that's a lot ...), it's 5 MWh so 1000 € per year saved.
In the worst case, it pays for itself in 6 years.

In a company that buys HT equipment, it is profitable over 5 years, and therefore it sticks with the chart of accounts.

It is not only the Covid that lowers the annual production sold by EDF (the self-consumption figures are totally bogus because few people declare themselves on the Enedis site to pay the Turpe producer ... well let's see)

Some yes, but few. First, because you have to be able to do it "physically" (being the owner of an individual good, able to accept the overload (or installation on the ground as you suggest, why not, but it takes up space), be financially able to do it (your self-build example is a bit caricature), and want to because, except in the case of electric heating (which PV will not solve), the electricity bill remains a relatively "reasonable" within a budget.

And concerning companies, yes for some who will want to "green" their image, but in the great majority of cases the investment expenses are generally devoted to the business core, not to ancillary things which are profitable over 10 to 20 years whereas the activity of the company (of the establishment) is often "questionable" over the horizon of a few years.

In short, I don't think that PV self-consumption is the "wave" that you seem to suggest, even if it is going to develop.

South Africa: Eskom invests heavily to operate Koeberg nuclear power plant for another 20 years

Image

Ecofin Agency 26 oct 2020

In South Africa, Eskom is investing more than $ 1,2 billion to extend the life of the Koeberg nuclear power plant. The investments of around $ XNUMX billion were made while the regulator has not yet authorized the planned changes.

In South Africa, Eskom has started investments of around $ 1,2 billion in the continent's only nuclear power plant, without first obtaining the approval of the sector regulator, according to Bloomberg. These investments aim to extend the operating life of the Koeberg power plant scheduled to end in 2024.

“Although there is still a lot of work to be done, Eskom is confident that it will receive a positive response to its request to extend the life of the Koeberg plant. That's why it invests heavily in spare parts, ”the company told Bloomberg.

However, this work, which aims to delay the closure of the plant for 20 years, worries activists. Eskom, for its part, announced the imminent arrival of the first of six steam turbines with a combined value of $ 1,2 billion that will allow the 1 MW plant to continue operating.

According to the regulator of the South African nuclear sector, the request for formal permission from Eskom for the extension of the plant is expected for next January. Modifications such as the installation of new generators “will have to rely on safety demonstrations for long-term operations. It is only after that that the regulator will be in a position to authorize or refuse this extension of the Koeberg plant, ”said Gino Moonsamy, spokesperson for the nuclear sector regulator.

Turkey.
Akkuyu's 3rd reactor receives its construction permit.

Turkey awards construction license for 3rd unit of Akkuyu NPP - report

Author Dragana Petrushevska PublishedNov 17, 2020

Turkey's energy and natural resources ministry said on Tuesday it granted a construction license for a third unit at Akkuyu nuclear power plant (NPP) to construction company Akkuyu Nuclear, local media reported.

The first reactor of Akkuyu, Turkey's first NPP, is planned to be put into operation by 2023, Daily Sabah quoted the energy ministry as saying in a Twitter post.

The power plant will have four units with a total installed capacity of 4,800 MW and will employ around 3,000 people. It will meet approximately 8% -10% of Turkey's current electricity consumption when operating at full capacity.

In 2010, Turkey and Russia signed a cooperation agreement for the construction of the nuclear power plant worth an estimated $ 20 billion (16.9 billion euro).

Russia's state-owned nuclear energy corporation Rosatom owns 99.2% of project company Akkuyu Nuclear which implements the project for construction and operation of the power plant.

Hungary.
The Paks2 power station receives its permit for 2500 MW. .

Paks 2 Nuclear Power Plant Gets Energy Office Permit

MTI-Hungary Today 2020.11.20

Hungary's energy regulatory authority (MEKH) has given its permit for the construction of the Paks 2 nuclear power plant, the agency said in a statement on Friday.

Atomerőmű Zrt, the company responsible for the project, submitted an application for a construction permit to MEKH in October 2020, the statement noted.

After examining the contents of the application to ensure that it complies with the relevant legislation, MEKH said construction of the plant with a nominal capacity of 2,524 megawatts can proceed, it added.

The agency considered the security of supply to the electricity network and the procedures related to the security of the nuclear technology carried out by the National Atomic Energy Agency in the course of its assessment, the statement said.

István Mittler, the Paks 2 project's communications director, told MTI that the MEKH permit was of “paramount importance”, similarly to such specific permits as the environmental permit and the site permit, preconditions for the construction, production, procurement and installation of the new blocks, as well as for the construction permit issued by the National Atomic Energy Agency

Yes. In addition, "10KW" is the peak or average power? If it is the peak one, with the day / night alternation and cloudy days, we will rather run at 1 or 2 KW on average. No question of having additional heating with so little.
I had seen some time ago if I could be completely independent. PV or wind resources do not interest me if I cannot cancel my subscriptions.
It is possible, but neither at an affordable cost, nor with a reasonable volume of equipment (in particular batteries) which would not transform the house into a quasi-industrial site. :frown:

In China, the new San'ao power station is at the start of construction. Casting of the reactor 1 slab. The projects for reactors 1 and 2 have been approved by the authorities.

Construction of new Chinese power plant begins

January 04 2021

The first safety-related concrete has been poured for the nuclear island of unit 1 at the San'ao nuclear power plant in Zhejiang province, China General Nuclear (CGN) has announced. A total of six Chinese-designed Hualong One pressurized water reactors are planned for the site.

In May 2015, the National Energy Administration approved the project to carry out site protection and related demonstration work. On 2 September last year, the executive meeting of the State Council approved the construction of units 1 and 2 as the first phase of the plant. China's National Nuclear Safety Administration issued a construction permit for the two units on 30 December. At 9.30am the following day, Yuan Jiajun, secretary of the Zhejiang Provincial Committee of the Communist Party of China and director of the Standing Committee of the Provincial People's Congress, issued a construction start order and a ceremony was held to mark the official start of construction of unit 1.

This project marks the first Chinese nuclear power project involving private capital, with Geely Technology Group taking a 2% stake in the plant. CGN holds 46% of the shares of the project company Cangnan Nuclear Power, with other state-owned enterprises holding the remainder.

CGN Chairman and General Manager Yang Changli said the company "will use the strength of the entire group to give full play to the advantages of more than 30 years of continuous nuclear power construction and the construction experience of the Hualong One, carry out the political responsibility for nuclear safety, and work with all participating units to build the San'ao nuclear power project into a quality project ".

In September, China's State Council also approved the construction by China National Nuclear Corporation and China Huaneng Group of two Hualong One reactors as the second phase - units 3 and 4 - of the Changjiang plant in Hainan province. Construction of those two units has yet to start.

The approvals for the new units followed a slowdown in conventional large-scale nuclear power project approvals in recent years. Eight new reactors were approved in 2015, but only the construction of a demonstration fast reactor was permitted between 2016 and 2018. Three projects were agreed in early 2019.

With the official start of construction of unit 1 of the San'ao plant, CGN now has seven nuclear power reactors under construction with an installed capacity of 8.21 GWe. It currently has 24 units in operation, with an installed capacity of 27.14 GWe.

Good news for the climate
Poland plans to order six EPR reactors from France

Nuclear power that could replace coal. Coupled with the development of renewable energies, Poland could do without coal as quickly as possible.
That's 78TWh theoretical annual.
Poland produces 120,5TWh per year from coal, 15TWh from gas, 1,8TWh from fuel oil and the rest from RES.
Theoretically, they will have transferred more than half of their emissions with these 6 reactors!
Following that, they will be able to undertake a decarbonization of the rest of their economy by electrification: heat pump for residential heat, electric car for transport, production of hydrogen by electrolysis for their industry, ...
Jean-Bernard Lévy notably went to Warsaw last week alongside Franck Riester, Minister Delegate in charge of Foreign Trade, to defend the French nuclear offer.

Franck Riester praised "a sector of excellence which has all the assets to support countries like Poland which choose decarbonation in the long term".

"In Poland all our interlocutors explain to us that there are in reality two options: the American option and the French option to provide Poland with six nuclear reactors," Jean-Bernard Lévy told deputies.
