China's first project to bring nuclear-generated heat to multiple prefecture-level cities has begun operation in Shandong province, supplying heat from the Haiyang nuclear power plant to the cities of Haiyang and Rushan through a 23 km pipeline.
The project is the third phase of a commercial heating project called Warm Nuclear No 1 operated by the State Power Investment Corporation (SPIC). After trials the previous winter to provide heat to the plant's dormitory and some local residents, the Haiyang plant officially started providing district heat to the surrounding area in November 2020, and then to the whole Haiyang city.
The Warm Nuclear No 1 project now reaches an area of 12.5 million square metres, and can meet the clean heating needs of about 400,000 people in winter, SPIC said.
Work began on the long-distance supply pipe in February, and the project has required coordination and communication between the different provincial and municipal bodies involved. Since the start of the Warm Nuclear Core No 1 project, some 83 km of nuclear energy heating main network and 11 first-level heat exchange stations have been built, with an investment of nearly CNY4 billion (USD555 million), SPIC said. To date, it has provided a total of 4.56 million Gigajoules (GJ) of zero-carbon heat, replaced 390,000 tons of raw coal consumption, and reduced carbon dioxide emissions by 720,000 tons, as well as improving winter air quality in Haiyang City.
The Haiyang nuclear power plant is home to two AP1000 pressurised water reactors which entered commercial operation in 2018 and 2019 respectively. Two CAP1000 pressurised water reactors are now under construction at the site with grid connection pencilled in for 2027.
Co-generated heat is very efficient. But I wouldn't want it from a nuclear plant.
@KevonLooney @Emil why is that?
You know exactly why. Acting like you don't understand people who dislike heating their homes with extra nuclear steam isn't the way to win people over.
I would use it if they heated Congress like that, or (since this is China) the CCP headquarters. Then you'll really know if it's safe.
@KevonLooney Ok, let's assume you're not trolling and you genuinely don't know that the tertiary cooling piping has zero contact with the reactor.
The primary cooling network goes through the reactor. The secondary network powers the turbine and already has no contact with the fuel rods in the reactor. The tertiary network is then used for the district heating.
So, there is no "nuclear steam" involved.
So, let's reverse our places and hope you weren't acting you didn't understand this.
@Emil
I have no problem with the technical specifications. I'm sure they're perfect. The problem is: research is performed by the brightest minds, but engineering is done by the lowest bidder.
On to the important part that you skipped: is this currently being installed in any buildings where leadership lives / works? If the Secretary of Energy lived in a house heated with this steam I would consider it.
That's how you know if it's good; do they "eat their own cooking"?
@KevonLooney I skipped that part because, in my opinion, it is completely irrelevant. But I do think that out of those 400,000 people receiving nuclear heat, there are bound to be party officials and other 'higher ups'.
You think the engineering part is irrelevant? Many things are theoretically safe, but fail catastrophically when actually built.
It sounds like you value progress at any cost. But I value knowing it's safe. If it's better and safer, top leadership will be falling all over each other to have this in their homes.
