Chennai, April 21 (IANS) Russia’s state atomic energy corporation Rosatom is planning to set up a series of 1,200 MW (BN-1200) fast breeding reactors and the first one is expected to be connected to the grid in 2032, senior officials said.

Once the BN-1200 reactors start functioning without an itch, Russia will offer the technology to other countries, they added.

According to them, Rosatom is hopeful of getting the BN-1200 design approval from the regulators next year and start construction in 2026 as part of the Beloyarsk Nuclear Power Plant (NPP) located in the Zarechny town.

“The BN-1200 reactor will be an IV generation sodium cooled reactor. The design is ready and regulatory approval is expected in 2025. The plant construction will begin in 2026 and will be connected to the grid in 2032,” said Andrey Smelov, Leader of the Technological Team for the construction of BN-1200 Unit recently.

“The BN-1200 reactor will be the first in the world of its size,” added Ilya Filin, First Deputy Chief Engineer, Beloyarsk NPP.

Smelov said the economics of BN-1200 is comparable with that of Russia’s VVER 1200 light water reactors (LWR), while declining to comment on the capital expenditure outlay for the proposed project.

The BN-1200 plant is an advanced version of the sodium cooled BN-600 and BN-800 fast reactors that were setup at the Beloyarsk NPP.

The proposed reactor is designed to handle different kinds of nuclear power fuels – uranium-plutonium mixed oxide (MOX) or the Nitride fuel.

Smelov said Nitride fuel is the next step for a closed fuel cycle.

He also said the BN-1200 reactor will not be occupying more space than the BN-800 due to the design.

The proposed reactor will have 400 fuel assemblies as compared to 647 fuel assemblies in BN-800 reactors.

“The fuel assembly size of the two reactors are different. After 180 days, the fuel assembly in BN-800 will be changed while in the case of BN-1200, the change will happen once in 330 days,” Smelov said.

As regards the safety systems, BN-1200 reactors have passive and active safety shut down systems.

Interestingly, the Beloyarsk NPP is the world’s largest NPP with fast neutron reactors and a pioneer in the introduction of uranium-plutonium mixed oxide (MOX) fuel.

The Beloyarsk nuclear power plant named after Soviet physicist Igor Vasilyevich Kurchatov is located 45 km east of Yekaterinburg city.

The Beloyarsk NPP has four power units: Two of them were shut down and are being decommissioned, and the other two units are operating.

Units 1 (1964-1981) and 2 (1967-1989) with water-graphite channel thermal neutron reactors AMB-100 and AMB-200 (Atom Mirny Bolshoi) were shut down as they reached the end of their service life and are being prepared for decommissioning.

The spent nuclear fuel was extracted from the reactors to be stored in the reactor cooling pools; in 2017, they began to remove the fuel from the site and transport it to a reprocessing plant in the Chelyabinsk region, said officials.

Unit 3 with the fast neutron reactor BN-600 is in operation. This is the world’s only power unit having a fast reactor with a commercial level of power, reliably and safely operated for such a long time.

The power unit was put into operation on April 8, 1980. In 2010, based on the materials expert examination of non-replaceable equipment (for example, the reactor vessel), and after the replacement including large-scale modernisation of the other equipment, and the introduction of additional safety systems, the power unit’s service life was extended until 2020 and then until 2025.

In addition, modernisation significantly improved its performance and economics, in particular, increased its electrical power.

Smelov said now work is on to extend Unit 3’s service life till 2040.

The construction of Unit 4 with the fast neutron reactor BN-800 (power capacity 880 MW) commenced in middle ’80s, which was suspended during the economic crises of the ’90s and recommenced in the 2000s.

For the first time, the BN-800 reactor reached the minimum controlled power level as part of its physical startup on June 27, 2014. The first connection of the unit to the grid and start of electricity generation took place on December 10, 2015. The unit was put into commercial operation on October 31, 2016.

BN-800, besides electricity generation, ensures the final stage for the components of the closed nuclear fuel cycle, which is necessary to achieve Rosatom’s strategic goal of nuclear energy transition to a new technological platform, which is the basis of two-component nuclear energy, the combined operation of thermal and fast neutron reactors.

To this end, BN-800 is operated with its core, fully loaded with innovative uranium-plutonium MOX fuel.

Unlike India that follows a three stage nuclear power programme — pressurized heavy water reactors, fast breeder reactors and thorium reactors — Russia has two phased programmes, light water reactors and fast reactors.

India recently entered the second phase of its nuclear power programme with the start of the ‘core loading’ of its sodium cooled 500 MW Prototype Fast Breeder Reactor (PFBR).

Upon completion of the core loading phase – which includes loading of the fuel, the first approach to criticality will be achieved, leading to generation of power subsequently.

The 500 MW PFBR is built by the Bhartiya Nabhikiya Vidyut Nigam Ltd (BHAVINI).

Once commissioned, India will be only the second country after Russia to have a commercial operating fast breeder reactor.

The PFBR will initially use the uranium-plutonium mixed oxide (MOX) fuel. The uranium-238 ‘blanket’ surrounding the fuel core will undergo nuclear transmutation to produce more fuel, thus earning the name ‘Breeder’.

The use of thorium-232, which, in itself, is not a fissile material, as a blanket, is also envisaged in this stage. By transmutation, the thorium will create fissile uranium-233 which will be used as fuel in the third stage. Fast breeder reactor is thus a stepping stone for the third stage of the programme, paving the way for the eventual full utilisation of India’s abundant thorium reserves.

In terms of safety, the PFBR is an advanced third generation reactor with inherent passive safety features ensuring a prompt and safe shut down of the plant in the event of an emergency. Since it uses the spent fuel from the first stage, fast breeder reactors also offer great advantage in terms of significant reduction in nuclear waste generated, thereby avoiding the need for large geological disposal facilities.

Nuclear power officials at Beloyarsk NPP are keenly watching the progress of India’s PFBR and would like to know more about the project.

Facing unexplainable mood disorders? You may be low on Vitamin B 12: Doctors

Published

on

By

New Delhi, July 6 (IANS) Vitamin B-12 plays a key role in producing brain chemicals that affect mood and other brain functions, said doctors on Saturday.

Vitamin B-12 (also known as cobalamin) plays a crucial role in the formation of red blood cells, cell metabolism, nerve function, and the production of DNA.

Some common symptoms of Vitamin B12 deficiency include strange sensations, numbness, or tingling in the hands, legs, or feet, difficulty walking (staggering, balance problems), anaemia, difficulty thinking and reasoning (cognitive difficulties), memory loss, weakness, or fatigue.

“Vitamin B-12 and other B vitamins play a crucial role in producing brain chemicals that affect mood and other brain functions. Low levels of B-12, as well as other B vitamins like vitamin B-6 and folate, may be linked to depression,” Dr Anshu Rohtagi, Senior Consultant, Department of Neurology, Sir Ganga Ram Hospital, told IANS.

“The deficiencies can result from poor diet or difficulties in absorbing the vitamins consumed. So, maintaining adequate B-12 level is essential for overall well-being, including mood regulation,” she added.

Vitamin B-12 is majorly found in poultry, meat, fish, and dairy products. It is available as an oral supplement, as injections, or nasal spray.

People who consume a vegetarian or vegan diet may be more prone to deficiency as plant foods do not contain vitamin B-12. The elderly and people with digestive tract conditions that affect the absorption of nutrients also are susceptible to vitamin B-12 deficiency.

“Vitamin B12 plays a crucial role in producing brain chemicals like serotonin, which helps regulate mood. When B12 levels dip, these chemicals can become imbalanced, potentially leading to symptoms like mood swings, irritability, and even depression,” Dr Guruprasad Hosurkar, Additional Director – Neurology, Fortis Hospital, Bannerghatta Road, Bengaluru, told IANS.

Importantly, the doctor explained that the “connection is not gender-specific. Both men and women can experience mood changes due to B12 deficiency”.

While research is ongoing, studies suggest a link between low B12 and depression, with some showing improvement in mood with B12 supplementation.

However, it’s important to note that mood swings can have many causes, and a doctor should be consulted to rule out other factors and determine if a B12 deficiency is present, Dr Guruprasad said.

“Vitamin B12 deficiency causes several neurological symptoms such as tingling, numbness & burning of feet, imbalance, memory impairment, mood disorders, psychosis, seizures, and Parkinsonism,” explained Dr Sudhir Kumar, from Indraprastha Apollo Hospitals, Hyderabad in a post on social media platform X.

“In a patient presenting with neurological or psychiatric symptoms, suspect vitamin B12 deficiency as a cause (especially if there is no obvious cause identified). Early diagnosis and prompt initiation of treatment rapidly improves patient’s symptoms,” he added.

The doctors also stressed the need to maintain a healthy lifestyle and advised key behaviours such as managing high blood pressure, and blood sugar, quitting smoking, and alcohol, staying physically active, getting adequate sleep, and managing stress.

Mice with functional humanised immune system shows promise

Published

By

New Delhi, July 6 (IANS) A first-of-its-kind mice model with a fully functional human immune system and a human-like gut microbiome has shown promise of mounting specific antibody responses.

To date, researchers have not developed a fully functional human immune system, but only those with a brief lifespan that do not mount efficient immune responses, making them unsuitable for the development of in vivo human immunotherapies, human disease modelling, or human vaccine development.

Developed by scientists at The University of Texas in the US, the new model will overcome limitations of currently available in vivo human models and is a breakthrough for biomedical research and promises new insight into immunotherapy development and disease modelling.

Detailed in the journal Nature Immunology, the new humanised mice, called TruHuX (for truly human, or THX), possess a fully developed and fully functional human immune system, including lymph nodes, germinal centres, thymus human epithelial cells, human T and B lymphocytes, memory B lymphocytes, and plasma cells making highly specific antibody and autoantibodies identical to those of humans.

THX mice mount mature neutralising antibody responses to Salmonella Typhimurium and SARS-CoV-2 virus Spike S1 RBD after vaccination with Salmonella flagellin and the Pfizer Covid-19 mRNA vaccine, respectively.

It is also amenable to developing full-fledged systemic lupus autoimmunity after an injection of pristane — an oil that triggers an inflammatory response.

“THX mice provide a platform for human immune system studies, development of human vaccines, and testing of therapeutics,” said Paolo Casali, Professor at the University of Texas School of Medicine in San Antonio, US.

They do this “by critically leveraging oestrogen activity to support human stem cell and human immune cell differentiation and antibody responses”, he added.
