This report is by far the best for-dummies explanation on how to produce weapon grade plutonium from a fast breeder. And the argument of "Each CFR-600 reactor can produce 200kg WgPu per year" is also derived from this report.
From my brief understanding, it is do-able by extract WgPu from fast breeder and tbh easier than I earlier thought from media report.
In short, each Chinese CFR-600 can produce
110kg WgPu (93.7% Pu-239) in a straight forward way by reprocessing radial blanket. In theory, another
62kg even superior WgPu (96.5% Pu-239) can be producing from chopping top and bottom sections of axial blanket by special equipment.
Disclaimer: I am not a nuclear physicist, dunno how real case will differ with theory. For example, initial core is made of HEU instead of MOX fuel. Though US media and Pentagon is more concerning in producing WgPu, I don't know whether it is true or scare campaign.
From famous (or infamous) "China’s Civil Nuclear Sector: Plowshares to Swords?" quoted by Pentagon report:
The report also agrees that it is not even hard to reprocess weapon grade plutonium from radial blanket. And super grade plutonium can be reprocessing in a more complicated method, but still achievable. "Since China lacks reprocessing capacity" is no longer true after China has started building
three 200t/yr reprocessing plant in Jinta and not to mention huge expansion in old Plant 404 where has added
three stacks in the newest round of construction. Normally it means three new factories as the existing factories have five stacks, so a 60% upgrade in Plant 404.
The NATO briefing reportedly said Plant 404 also built a new reactor, which is not required in a purely reprocessing plant, unless they want to reprocess WgPu in a traditional way like they did back in 60s.
The interviewee is probably indicating that first reprocessing plant has been completed and the second one is being built with a construction period of 3 years, so probably completed by 2024 -2025, the third one is likely to be completed by 2026 - 2027.
Not only the quantity of reprocessing plant has already exceeded widely reported number, but also the construction speed is faster one over the other.
