The entire civil construction of Kudankulam NPP was agreed by

both sides to be executed as per the construction norms and

procedures prevalent in India. Nevertheless, the Russian side

included various advanced systems of construction not yet

executed out in India. Some of the important construction

features of KKNPP are as follows.

The 55C15, pre-stressing system has been designed by

M/s. Freyssinet, France. In this system, each pre-stressing

tendon consists of 55 numbers of steel strands, 15.7mm in

diameter. Each strand is composed of 7 plys and has a sectional

area of 150 mm2. Each strand is housed in a HDPE sheath filled

with grease.

China General Nuclear (CGN)has begun loading fuel into thecore of unit 1 of the Taishannuclear power plant in China'sGuangdong province followingthe issuance of a permit fromthe regulator. The unit is laterthis year scheduled to becomethe first EPR (Thirdgeneration pressurised waterreactor, PWR) reactor to enteroperation.

The US Nuclear RegulatoryCommission (NRC) has approvedthe issuance of combinedconstruction and operatinglicences (COLs) for the twoproposed AP1000 reactors at

Florida Power and Light's (FPL's) Turkey Point plant in Florida. The

Turkey Point site, about 40km south of Miami, already features two

operating 800 MWe reactors built in the 1970s. Unit 3 is currently

licensed to operate until July 2032 and unit 4 until April 2033. The site

also includes three gas-fired units.

The reactor is thesixth to be restarted afterclearing the country's revisedsafety regulations. The NRAannounced in May 2017 thatthe two units meet safetystandards introduced in July 2013. The NRA approved Kansai's plan forstrengthening the units in August last year. The regulator subsequentlyconducted pre-operation inspections of the units to confirm that thesafety countermeasure equipment complies with the approvedconstruction plan at the plant. The governor of Fukui Prefectureapproved the restart of Ohi units 3 and 4 in November.

Spring of 1954 saw TheEngineer reporting onUSS Nautilus, the world’sfirst nuclear submarine, apioneering piece ofengineering.

Its reactor had beeneven longer in theplanning, withWestinghouse ElectricCorporation instructed todevelop a nuclear powerplant for a submarine asfar back as 1947. Theresult was the SubmarineThermal Reactor(STR, later redesignatedthe S2W), a pressurisedwater reactor thatdelivered 13,400hp(10,000kW) of power.Decommissioned in1980, today Nautilus is amuseum ship in Groton.She was designated aNational HistoricLandmark in 1982.

NASA and Columbia University found that nuclear power may havesaved 1.8 million lives that otherwise would have been lost topollution from emissions. Nuclear electricity promotes people’s well-being by improving air quality, providing jobs and stimulatingeconomies.

Magnox

Nuclear Terminology

More on Magnox

Lexicon

“Magnox” stands for Magnesium Non-Oxidizing, a term thatdescribes the magnesium alloy cladding used on the carbondioxide cooled, graphite moderated reactors of this type. In1956, the first reactor of the Magnox type — one of aneventual eight at Calder Hall — was dedicated by QueenElizabeth II and placed in service. Eventually very much largerunits were built, optimized for commercial power service(instead of dual power production and plutonium productionas initially envisaged) and the type went on to have a long andsuccessful history in the UK.

Magnox is a type of nuclear power/production reactor that wasdesigned to run on natural uranium with graphite as themoderator and carbon dioxide gas as the heat exchange coolant. Itbelongs to the wider class of gas cooled reactors.

The first magnox reactor tocome online was CalderHall (at the Sellafield site) in1956, frequently regarded asthe "first commercial-scaleelectricity producing reactorin the world", while the lastin Britain to shut down wasReactor 1 in Wylfa (on YnysMôn) in 2015.The magnox fuel elements

consisted of refined uraniumenclosed in a loose-fittingmagnox shell and thenpressurized with helium. Theoutside of the shell wastypically finned in order toimprove heat exchange withthe CO2.Like the Windscale

designs, the Magnox reactorsallowed access to the fuelchannels and couldbe refuelled whileoperating. The Magnoxdesign was superseded bythe Advanced Gas-cooledReactor, which is similarlycooled but includes anumber of changes toimprove its economicperformance.

What is Biochar? How NuclearTechnology paves the way for Climate-Smart Agriculture?

Trivia

Biochar is charcoal used as a soil amendment.

Biochar is a stable solid, rich in carbon, and can

endure in soil for thousands of years. Like most

charcoal, Biochar is produced through pyrolysis or

gasification — processes that heat biomass in the

absence (or under reduction) of oxygen.

Nuclear Trivia

Pineapples and biochar:Costa Rica generatesmore than 10 milliontonnes of pineappleresidues as a by-productper harvest — every 18months — so theydecided to use theseresidues to producebiochar. Reducingpineapple residue isespecially important,because it offers abreeding ground for thestable fly, an insect pestthat is devastating cattle.

Biochar is a PowerfullySimple Tool to CombatClimate Change:In addition to creating asoil enhancer,sustainable biocharpractices can produce oiland gas byproducts thatcan be used asfuel, providingclean, renewable energy.When the biochar isburied in the ground as asoil enhancer, thesystem can become"carbon negative.”Biochar and bioenergyco-production can helpcombat global climatechange by displacingfossil fuel use and bysequestering carbon instable soil carbon pools.

THE SCIENCE:Carbon sequestration in soil:Soil is a mixture of minerals, organic matter, gases

and water. Carbon is a key ingredient of soil and its

health, but, in a gaseous form as CO2, it is a GHG.

Plants capture carbon in the form of CO2 from the

air, transforming it into organic matter and thereby

transferring it into soil, which boosts soil productivity

and resilience to harsh climate conditions.

The idea of soil capturing and storing atmospheric

carbon dioxide (CO2), also known as carbon

sequestration, can counterbalance the increase of

GHGs. Analysing carbon isotopes allows

researchers to evaluate soil quality and sources of

carbon sequestered in the soil. By measuring

carbon sequestration, they can identify whether

biochar is enhancing soil fertility and helping reduce

CO2 emissions.

Similarly, by using fertilizers in defined plots labelled

with the nitrogen-15 stable isotope (15N) scientists

can track the amount of nitrogen taken up by plants

or lost to the atmosphere as GHGs or to surface

and groundwater, and can determine how effectively

the crops are taking up the fertilizer. This helps

them optimize fertilizer use on farms.
