Bangladesh to join in Indo-Russia nuclear cooperation

[Nilgiri]

disregard the cheap trolls. The deal is beneficial to the bangladesh , know it direct from horses mouth the sputnik. Contrary to what hate mongers say,defence deal is for supply of spare parts for mig.

India is set to sign a deal with Bangladesh for providing infrastructure support in the field of nuclear energy to the latter’s Rooppur nuclear power plant which is being established with assistance from Russia’s Rosatom.

India Sets New Target for Nuclear Power Generation by 2024
New Delhi (Sputnik) – The service provider deal for the Rooppur plant will be signed during Bangladesh Prime Minister Sheikh Hasina’s visit April 7 onwards.
With defense and energy co-operation between Russia and Bangladesh deepening further, Delhi will provide close to $1 billion credit support to Dhaka at very low interest rate. This deal is also expected to provide substantial business for Indian companies in the supply of raw materials for infrastructure.

During the Sheikh Hasina visit, India is expected to ink a deal to supply military hardware including spare parts for Russian-origin aircraft and helicopters of the Bangladesh Air Force. The Bangladesh armed forces have Russian-origin MiG-29 and MiG-21 fighter aircraft, MI-8 and MI-171 helicopters.

“Both countries are involved in giving a final shape to the proposed umbrella agreement. Serious discussions are underway,” said sources. Ahead of Sheikh Hasina’s visit, Indian Army chief General Bipin Rawat will be visiting Dhaka on March 30.

Rawat will meet Bangladesh President Abdul Hamid, Sheikh Hasina and other defense officials and is expected to discuss issues related to the umbrella agreement.

Bangladesh has initiated the process to procure eight multi-role combat aircraft (MRCA) for the country's air force, with an option of buying four additional aircraft. Russian manufacturers are expected to win the contract. If Bangladesh decides to purchase MiG-35 or Sukhoi class aircraft, the Indian government expects to bag the contract for their service and maintenance of the Russia-built aircraft. However, India may need Russian approval to supply military hardware to Bangladesh, if India-Russia agreements specifically mention it.

Yeah I got it now....it was case of mistitle at the beginning.

nvm then... i thought the op talked about silos... because of a bangla word he mentioned....

yah even title of the thread was originally "missile defence"....so I got really confused too. Like what does missile defence (an apex largely research based defense sector) and BD have in common yet etc...

basically the agreement the russians will conduct the training part for indians and bengals together in the indian plant... and future sharing of information/ data/ experience related to the reactors.... i believe you guys are also getting VVER 1200 ?

VVER 1000 for India (as far as the russian reactor designs go). Couple things regarding VVER 1200 were developed for the specific VVER 1000 iteration in India.....so there is huge commonality between the two. VVER 1200 is basically 1200 MWe and VVER 1000 is 1000 MWe (per reactor).

and this arrangement even after its signed can be terminated by any of the three countries at any time without any heads up! i think it's not a bad idea at all to share information and experience of operating the plant.... especially if they're similar specs, might help prevent any possible disaster from experience learnt from one another.

Yes its just a good training portal. You know how -25 C weather is like....so you BD nuclear technicians/operator can enjoy TN weather during the training instead hehe. Masala Dosai and such instead of borscht

As for disaster mitigation, this is a very safe reactor (with many passive safety). USSR should have gone for this design everywhere instead of that stupid graphite moderator design they used in chernobyl....that design was inherently unstable (much like a very maneuverable aircraft is - and hence why it needs computer FBW control) and basically relied on control system safety rather than inherent passive safety. So any safety training for VVER will involve not getting in the way of the system doing what it will inherently do if something goes wrong in the first place (has to generally be a foreign induced reactor breach).

nah i am fine with kuwaits sun turned up to 60c
will go on april for a weeks then go to turkey for a week vacation and return back to ukraine....
pretty much still haven't tried borscht.... but have done all of arab cuising here xD


during the soviet times when chernobyl reactors were built... soviets didn;t had as advanced tech as they have now... like everything soviet/russian starts with a trash can that just works.... but later becomes something really cool.

i wonder if international students will be allowed to take a cavation to chernobyl

May be you can but you might need special suits to evade from russian police/forest guards or a drooling black grizzly.....

you can give a shot at https://chernobyl-tour.com/permit.html

Actually VVER design goes back to 60s....and even VVER-1000 is from mid 1970s. They could have easily chosen VVER as their scaleable mass design.

But like their cheap lada, they went for mass production rather than the improved quality/safety....and RBMK reactor was very cheap compared to VVER...positive void coefficient be damned! Results are there to see in hindsight.

too baad... it's in ukraine now

i remember scientist raising questions regarding use of VVER 1000 in our country... later russia offered 1200 claiming it features multiple safety features... i am not so enlightened on russian reactors so cant really say anything...

yes 1200 has added even more on 1000 (just like the indian vver 1000 that was proving ground for lot of them).

1000 is not really offered for export anymore I believe. India is just creating more 1000 reactors because that is what our production at home is geared and fully certified for.

RBMK basically had a real fundamental flaw (hence this tech never got incorporated in the west in any large scale past a few early test reactors).

This flaw was if the thing started to overheat (through cavitation - the main avenue for that...i.e the water leaking out or steam impulse etc), the nuclear reaction "rate" would actually increase....means you have a potentially terrible feed back loop if your control system cant handle it or is compromised.

That is what happened in chernobyl essentially. It went into an uncontrolled trajectory of heat addition----> more void created---> more heat addition etc till the steam explosion (from the steam impulse generation) happened and the graphite moderator physically caught fire. Control system basically couldnt handle the resolution of that surge (which only started because they were running some tests in the first place...which is another stupid decision if you understand the details of how many checklists were not followed).

Noobs think it was a "nuclear" explosion....but that was not the case....no nuclear reactor in the world is capable of that since that requires an uncontrolled chain reaction of the nuclear fuel itself (which cant happen in nuclear reactors).

This very mechanic of failure is impossible in VVER (from the get go...whatever model it is...even VVER 440 or test VVER) because as soon as you start the heat addition (from cavitation)....the nuclear chain reaction drops in rate (it actually needs the moderator i.e water to create the heat). This is the standard negative void coefficient I am talking about that is common sense for anyone. Then you add all the extra safety and such on top of this....to handle the further cooling required in an event of the shutdown to prevent say fukushima incidents from happening or 2nd loop issues like three mile island from happening. Neither of those two incidents were a primary operation failure like chernobyl because of their inherent negative void coefficient.
