Nope HPR1000 is an evolution of CPR-1000 using the 3-loop French M310 design IP owned by AREVA.

CPR-1000
(‘Improved Chinese PWR’) design, with an electric output of 1000MWe, is based on the 900MWe 3- loop French M310 plants and make the largest proportion of current reactors under constructions.
Even though China has a nearly complete domestic supply chain for the CPR-1000, the intellectual property rights are retained by AREVA and thus restricts its use to domestic market.
ACPR-1000
Power Corporation based on the
CPR-1000 (CGNPC) with full Chinese intellectual property rights. The design focuses on the safe performance of the reactor while improving the economic efficiency.
This enhanced version of the 3-loop CPR-1000 has higher seismic standards, features a double containment and a reactor core catcher for SA mitigation purposes.
Hualong One (HPR1000)
The Hualong One, now officially called the HPR1000 by the Chinese government, is the result of China National Nuclear Corperation (CNNC) and CGNPC merging their design as suggested by the Chinese National Energy Administration. The Hualong uses systems from
CNNC’s ACP-1000 and CGNPC’s ACPR-1000. Both reactors were conventional 3-loop PWRs, but ACP-1000 core design was finally adopted to be placed in the Hualong One
