Coal crisis:

Nuclear plants are operating at near full capacity and exceeding their planned targets which is rare as purchasers prioritise cheap coal based power over nuclear if they can avoid although it is against the Central guidelines.

Central guidance says Solar+Wind+Hydro+Nuclear are Must Run category which means any power produced should be considered primary and purchased in full at any PPA price. Cheaper Coal and other thermal is considered dynamic load and should cover the rest only.

KAPS-1, MAPS-1, NAPS-1 are down for their 20-year enmass refuelling. KAPS-3 is operating at low load although it is still in tetsing and not commissioned and is not reflected in this report as it is directly selling to exchange.

Data for September: (October data is much wilder - We are only 10 days into october but they exceeded their 17 days target)

Tenders have been released to complete the final phase of BARC Vizag campus.

Next likely efforts could include start of construction work on High Flux Research Reactor and Innovative High temperature Reactor ar Vizag.

NFC Kota construction seems to be nearly complete and will be primary supplier to all the new PHWRs comping up.

GHAVP-1&2 foundation work seems to be nearing completion. Main buildings likely to start construction around January.

KAPP-4 few months away from completion. Covid delayed this one significantly.

RAPP-7&8 are each a year away from completion.

But most of these delays are due to HR issues and not execution issues. KAPP-4, RAPP-7&8 commissioning and GHAVP-1 &2, KKNPP-3 to 6 construction are putting incredible stress on HR resources in NPCIL. They don't have enough trained and experienced people to execute so many projects at the same time. They are being stretched too far. Training and experience validation of new people takes time.

Little correction to it. We no longer have any shortage of Uranium after we found massive reserves in Andhra Pradesh. Infact our uranium reserves are now equal to that of America and among the largest in the world.
According to Wikipedia
India 129000 tons and usa 138000 tons.

Now import is still welcome as it will take time and money to mine actual uranium and process it.

But thankfully we have no shortage . We can ramp up our nuclear program whenever we want.
Are you sure of this? Sorry, I don't follow nuclear news as it is too sciency for an expedition specialist like me. But out of curiosity and being a taxpaying citizen, I just wanted to that if we sufficient reserves, assuming that it was a mining study that found the new reserves in Andhra, how come we are not building civil nuclear power plants left, right and centre on a war footing to cut down the coal-fired power plants that generate 56% of our national power?

As per DAE, estimated Uranium reserve in India is about 3,50,000 tonne.

We aren't building fast due to financial limitations, manpower limitations and site land acquisition issues.

Each plant requires USD 4 Billion for a single unit and GoI doesn't have so much to spare for power plants as the money is being spent on other infrastructure.

Instead, GoI wants project financing for all new power plants mainly from the likes of World Bank, japan, ADB etc. Solar, Wind and other power plants are being financed through this method.

The above international financing method is not available for nuclear plants and hence we have to rely on other methods or pay full cost out of pocket.

Govt currently only has approved financial sanction for 5 plants and is further planning 10 more out of it's own capex budget and local sovereign guaranteed borrowings.

To build more we need external financing which is only possible via government to government deals like Kudankulam where the financing countries expect the reactors to be their designs to support their industries

Hence, this is why govt is courting the French, Americans and Russians for Jaitapur, Srikakulam and Kudankulam respectively although we have our own designs we can build. But French and American projects aren't moving ahead easily due to other resons - French designs are too expensive and not economically viable, the American Westinghouse was recently bankrupt and doesn't have assets to secure funding for their. Russian ones are moving ahead.

Chutka (MP) and Mahi Banswara(RJ) land acquisition is going slower than expected due to local opposition. Haripur(WB) isn't moving at all because WB state govt is not cooperating with centre. One site in Gujarat was cancelled and moved to Mahi Banswara because of local political issues

TL;DR; There is no money build too many at a time.

Hearing that the AHWR design is fully complete and BARC/NPCIL have applied to AERB for Construction consent for the first unit at Tarapur.


As per the 2017 plan this was supposed to be complete by December 2020 but this was delayed due to slow down in experiments due to covid.
One of the reasons that the design took so much time was because the fuel fabrication was too unsafe for operators even while hotcells were being utilised and forced BARC to chnage the fuel loading design to make the fuel fabrication safer.
This required the revalidation of all physics parameters.

The fuelling machine prototype, the coolant pumps have all completed five years of validation testing.

The designs for all components including reactor building, turbine building and associated buildings are complete.

C&I, Physics database have also been completed and signed off.

AERB is conducting the final Consenting design review.

NPCIL is awaiting PMO and FinMin clearance to start publishing tenders.

Real Construction start likely from Mid-2022. Commissioning by 2025-27. If they receive PMO and FinMin approval
