| > Unfortunately its just a small boiling water reactor. It is not just a small boiling water reactor. It is a 300 MW-electric boiling water reactor, and if successful, it will be followed by 3 more of the same type for a total of 1.2 GW-electric. That is more than an AP-1000 reactor, and much less risky. |

| > Larger reactors are needed. Genuine question: Why? Why not many smaller reactors? Small modular reactors seem pretty neat. Is there an efficiency loss/total cost difference with smaller reactors? |

| ▲ | fsh 3 hours ago | parent [-] | | Like most industrial sites, large reactors are much more economical than small ones. This is why nobody has built SMRs since the 1950s. | | |
| ▲ | ChadNauseam 24 minutes ago | parent [-] | | The basic premise of "have a factory that produces reactors small enough to ship" always made sense to my uneducated mind. Is there a flaw in the idea? It seems like it should be much cheaper than if every reactor were bespoke | | |
| ▲ | fsh 6 minutes ago | parent [-] | | With smaller reactors, one needs more of everything: reactor vessels, containment structures, cooling systems, generators, etc. This is why industrial facilities are usually built as large as reasonably possible, and why SMRs fell out of fashion as soon as GW-class reactors became feasible in the 1960s. |

| I mean, Ontario runs the Bruce nuclear plant which is the second largest in the world in terms of the power it generates at 6,610 MW, Japan gets the top nod with a plant that generates 7,965 MW. |

| ▲ | chollida1 7 hours ago | parent [-] | | You could be right about the Korean plants. I only relied on google to give me the top 5 nuclear plants active in the world. The Korean plants you mention were not on the list. | | |
| ▲ | manquer 5 hours ago | parent [-] | | Wikpedia has more info, plus WNN and other industry publications usually are more up-to date. Kori[1] has 7 operational units today and 1 commissioning and 1 under construction Hansul[2] has 8 operational units and another 2 more under construction. All 4 new units are APR-1400 reactors ~1400 MW capacity. Kori should retains its top position, Saeul-3 in Kori Phase II has already reached criticality in April. Tianwan in China will come close but its 7/8 units are slightly behind in construction than Saeul-3/4 in South Korea, plus the plant is also bit smaller at 6600MW now . The Russian VVER-1200 design China are using is also slightly smaller than Korean APR-1400.
