March 11, 2016

According to officials, the leakage of heavy water that is used in cooling off the nuclear reactor core was detected around 9 am and it was fixed in some time and the temporary emergency was lifted shortly afterwards.

Surat District Collector Rajendra Kumar said there was no leakage of radiation at the plant and the situation was under control. The incident took place on a day when Japan marks the fifth anniversary of Fukushima nuclear disaster caused by a monster tsunami.

KAPS site director L K Jain in a statement said radiation levels in and outside the plant are normal.

"Unit-1 of KAPS, which was operating at its rated power, was shut down at about 9:00 Hrs today. Consequent to a small leak in Primary Heat Transport (PHT) system, the reactor was shut down as intended as per the design provisions. All safety systems are working as intended," the statement said.

"The radioactivity/radiation levels in the plant premises and outside are normal. KAPS 1 and 2 consists of two Units of Pressurized Heavy Water Reactors of 220 MWe each," Jain added.

The KAPS, located on the border of Surat and Tapi districts near Vyara town of Tapi, is run by Nuclear Power Corporation of India Ltd (NPCIL).

"The director of the plant informed me that unit-1 has been shut down following a problem in the primary heat transmission system. There was some leakage of heavy water that is used in cooling the reactor core. At present, the situation is under control," Rajendra Kumar told PTI.

According to KAPS website, the power station has two generation units of Pressurised Heavy Water Reactors (PHWR) that were commissioned during early 90s.

"The problem was detected in the morning and it has been fixed as of now. The plant also declared temporary emergency, which has been lifted after some time.
As of now, there is no emergency and things are under control. We are told that Unit-1 will take some time to start functioning again," Kumar added.

Meanwhile, neighbouring Tapi district administration also swung into action and sought details from plant officials after learning about the leakage. Tapi District Collector B C Patni also confirmed that there was no report of radiation leakage.

"The problem occurred in Unit-1 of the plant at around 9 am. As per the reports received from the site director, all the employees are working in the plant and no internal or external radiation leak took place. The leakage of liquid has been fixed," said Patni.

New Delhi, Jan 28: Kolkata Metro Rail Corp expects to complete its East-West project, which runs partly under the city’s iconic Hooghly river, by March 2022 after a delay of several years doubled costs.

The authority is awaiting a final installment of Rs 20 crore ($2.8 million) over the next two years from the Indian Railway Board, said Manas Sarkar, managing director at KMRC. A soft loan of Rs 4,160 crore from Japan International Cooperation Agency helps fund 48.5% of the project.

India’s oldest metro, which started in 1984 with a North-South service, was due to expand by 2014 but faced problems including squatters on the planned route. These issues have contributed to the total project cost rising to about Rs 8,600 crore for some 17 kilometers from Rs 4,900 crore for 14 km.

“About 40% of total transport demand will be tackled by these two metro services,” Sarkar said in an interview at his office in Kolkata. “It will be a relief for environmental pollution and the city should be much more decongested.”

The new line is expected to carry about 900,000 people daily, -- roughly 20% of the city’s population -- and will take less than a minute to cross a 520-meter underwater tunnel. Depending on the time of day, it takes some 20 minutes to use the ferry and anywhere upward of an hour to cross the Howrah bridge.

KMRC will repay the JICA loan over 30 years after an initial six-year moratorium. The interest rate is between 1.2% to 1.6%. The East-West metro project is 74% owned by the railway ministry and 26% by the ministry of housing and urban affairs.

“We don’t anticipate any further cost escalation now,” Sarkar said.

New Delhi, Jun 20: The government-imposed upper and lower limits on airfares may be extended beyond August 24 depending upon how the situation turns out, Aviation Secretary P S Kharola said on Saturday.

The government resumed domestic passenger flights from May 25 after nearly two months of suspension to combat the coronavirus outbreak, but placed lower and upper limits on airfares depending upon the flight duration.

It had said on May 21 that these limits would be in place for a period of three months.

"Depending on how the situation turns out, the fare band may have to adjusted beyond that (August 24) also. But right now, it is only for three months," Kharola said at a press conference here.

International passenger flights continue to remain suspended in the country.

However, the government started Vande Bharat Mission on May 6 to help stranded people reach their destinations through special flights.

Aviation Minister Hardeep Singh Puri said at the conference that during phase 3 and phase 4 of the mission, private domestic airlines have been approved to operate 750 international flights to repatriate people stranded amid the coronavirus pandemic.

Kozhikode, Aug 8: A tailwind or crosswind could be the reason for the Air India Express flight mishap at Kozhikode international airport in Kerala, according to some aviation experts. 

Team of DGCA and AIE already reached the spot. With the death of the captain and co-pilot in the mishap, the investigation would be focusing mainly on the voice recorders and other technical aspects.

It is learnt that the ill-fated aircraft, IX 1344 with 190 onboard including crew, was initially planning to land on runway-28 of the airport. But later the pilot opted runway-10 which is toward the other direction. Pilots would be taking the decisions on the basis of inputs from ATC.

The questions now doing the rounds are what made the pilot opt runway-10 and whether the tabletop runway lacked adequate safety parameters.

An aviation expert, who didn't want to be quoted, said that Capt Deepak Sathe, who was commandeering the aircraft, was a well-experienced pilot and was also familiar with the terrains. Hence the chances of any error from his part was very unlikely. Hence a fair in-depth probe was required to find the exact cause.

Though the Kozhikode airport has an Instrument Landing System, it was of category-I for which pilot's visibility is very crucial toward a touchdown. Since it is a tabletop airport and rough weather prevailing in the region, the chances of tailwind was also high, said sources.

There had been safety concerns about the airport over quite some time. In 2011 aviation safety consultant captain Mohan Ranganathan reportedly gave a report citing the safety issues, especially the buffer zones at the end of the runway.

However, an AAI officer said that rectification steps were already done by last year by widening the Runway End Safety Area (RESA) from 90 metre to 240 metre. However, the length of the runway had to be reduced to 2,700 metre from 2,850. The AAI was also constantly pressing for increasing the runway length to 3,150 metres. But that was getting delayed due to land acquisition issues pending with the state government.
