As reported by the South China Morning Put up on September 28, 2020, China’s State Energy Funding Company Restricted (SPIC) has introduced the completion of the event of their third technology nuclear reactor known as CAP 1400 or 国和一号. Based mostly on AP1000 know-how from Westinghouse,
“the CAP1400 has two main coolant loops that switch the warmth generated by the fission response of 235U within the reactor core to the steam generator (SG). Every loop consists of a scorching leg, two chilly legs, one SG, and two canned pumps. CAP1400 has one pressurizer (PRZ) related to one of many scorching legs by a surge line.” https://www.sciencedirect.com/science/article/pii/S2095809916301539
SPIC additionally introduced that the 3G know-how is backed by over 1,052 patents and 6,513 mental property functions. Nonetheless, an inventory of those patents and functions was not offered.
FIG. 1 of “The Normal Design and Know-how Improvements of CAP1400” exhibiting the reactor design
Looking for Chinese language patents below the Shanghai Nuclear Engineering Analysis and Design Institute and the SPIC utilizing the Incopat database yielded 1,007 invention patents and functions and an additional 605 utility fashions. Many had co-applicants exhibiting the nationwide effort that went into creating the know-how.
Wanting on the invention patents and functions, gas meeting and reactor coolant loop had been the primary focuses of patenting in response to an Incopat evaluation. This matches with the announcement that acknowledged the analysis “broke many technical monopolies together with principal pumps, blasting valves, stress vessels, steam turbines, reactor internals, management rod drive mechanisms, giant forgings, nuclear-grade welding supplies, and 690U pipes, and so forth.”
Based mostly on the submitting dates proven within the Patenting Exercise chart under, we are able to see that analysis and improvement accelerated in 2012 and peaked in 2015. Observe although there’s a lag in information as invention patent functions are usually revealed by 18 months from submitting so the lower proven in 2019 and 2020 might not be as steep as indicated. Nonetheless, the lower does match the announcement that improvement is full.
Only a few examples of granted invention patents embody:
Welding restore methodology for nuclear energy gear manufactured from low-alloy high-strength metal CN106695144B
Concrete composite reinforcing materials for waste disposal container and preparation methodology thereof CN106396445B
Technique for separating radioactive waste water of boron in methodology and gadget CN106653132B
Passive nuclear reactor security injection system CN103295654B
The deployment of those new 3G reactors ought to assist President Xi obtain his admirable purpose of carbon neutrality for China by 2060 as nuclear reactors, throughout operation, do no emit greenhouse gases resembling carbon dioxide.
