Did a quick research on PHWR as its stands today in the world.

Only India is actively building (5 x 630MW) and planning more (8 x 630 MW) reactors of this design type (PHWR).... with the current series known as IPHWR-700.

Romania has 2 planned, but these are restarting unfinished projects ordered from Canada (CANDU-6) in thee 1980s, they operate 2.

============================================================================================================


Operational MW (reactor number)
Building MW (number)
Planned MW (number)
Shutdown MW (number)

Roughly:


Argentina:

O: 1600 MW (3)


Canada:

O: 15000 MW (19)
S: 1850 MW (6)


China:

O: 1350 MW (2)


Germany:
S: 50 MW (1)


India:

O: 5700 MW (19)
B: 3150 MW (5)
P: 5000 MW (8)


Pakistan

S: 90 MW (1)


Romania:

O: 1300 MW (2)
P: 1300 MW (2)


South Korea:

O: 2000 MW (3)
S: 657 MW (1)


Sweden:
S: 10 MW (1)


USA:

S: 17 MW (1)

It looks like they will first operate and verify everything with U-238 --> Pu-239 breeding before moving onto Th-232 ----> U-233 (the long term objective as set out by Homi Bhaba back in the 1950s.)

============


"The 500 Mwe-Prototype Fast Breeder Reactor (PFBR) in Tamil Nadu’s Kalpakkam is expected to achieve first criticality within six months, marking a key step towards India’s energy independence.

With fuel-loading nearly complete, India is on track to become the second country after Russia to operate a fast breeder reactor.


The PFBR in Kalpakkam began receiving fuel on 18 October after the Atomic Energy Regulatory Board (AERB) granted permission this month."

No news on the Thorium reactor?

The 1st large one is the PFBR - prototype fast breeder reactor ( incorporating what is learned from the smaller two test reactors: KAMINI and FBTR).

Earlier last year they said it will achieve criticality around this month (March 2026) and start operations later in september this year


Maybe it is delayed somewhat further, we have to see.

This is the 2nd stage of 3 stage program, i.e producing comprehensive steady amount of U-233 from Th-232.

The 3rd stage will be the AHWR (advanced heavy water) reactor, that will be constructed later pending what is learned from producing U-233 in the PFBR. That's the one that will actually use the surplus U-233 produced by the PFBR.
