Vermont Yankee fixes new leak, powers plant back up

first_imgAs of Tuesday afternoon, the plant is operating at 100 percent power ~615 megawatts after reconnecting to the New England power grid early Saturday morning. Plant power will vary slightly over the next several days while operators perform rod pattern adjustments to the reactor to achieve 100% steady state operation.Source: Vermont Yankee. 6.1.2010 Northstar Vermont Yankee,During plant start-up activities Friday night, plant operators at the Vermont Yankee nuclear power plant in Vernon identified a condition described as vapor and water dripping in the Advanced Off Gas excavated area. The volume was estimated to be extremely small and occurred over a period of approximately four hours. According to Yankee, this was a new leak. The leak has been stopped and there is no leak at this time. Yankee said there is no threat to public health or safety.The vapor and water dripping was identified at approximately 7:30 pm during warm up of the AOG system. No leakage was visible after warm up and shortly after the AOG system was placed in service. The leak was located on a two-inch drain line and is approximately one-eighth of an inch in diameter.The vapor and water dripping was observed coming from the end of a concrete enclosure surrounding a two inch drain line in the AOG excavation just before the pipe enters the wall of the drain tank room. Soil testing of the area was performed and tested positive for several radioisotopes in a one-foot radius from the leak source.The surface areas where water had previously been observed were sampled for surface contamination.  Samples were positive for tritium.  A sample of wood that had been exposed to the leak and soil below the leak site showed measurable levels of radio-isotopes.  Isotopes detected were chromium-51, manganese-54, cobalt-58, cobalt-60, zinc-65, zinc-69, niobium-95, rhodium-105, xenon-131, cesium-137, barium-140 and lanthanum-140.  Some of these isotopes (rhodium-105, xenon-131, barium-140 and lanthanum-140) are short lived and are evidence that the contamination was recent.Yankee said its current plans are to remediate the soil at the area of the leak and evaluate the condition of the two inch drain line. Repair options under evaluation include removing the line from service, replacing the line, or performing an on-line leak repair. The identified leak should not reoccur during normal plant operation, with the AOG system in service.The NRC and State of Vermont were notified.Vermont Yankee was reconnected to the New England electrical grid shortly after midnight Saturday.On Sunday and Monday, Vermont Yankee engineers and maintenance personnel worked to develop a repair technique to isolate the 2 inch AOG drain line, which was the source of minor leakage during plant startup on Friday night.  During development of the procedure, a test mock-up was made that simulated actual condition in the in-service pipe.  The repair process involves drilling into the pipe at two locations and injecting compounds that harden as they cure.  A different compound is then injected between these two locations that expands to become a rubber like plug.The technique was validated about midday on Monday, and repairs were then begun on the 2 inch drain line.  The repairs were completed by about 6:30 pm on Monday.  This effort successfully isolated this line within the AOG Pipe Tunnel, by installing the sealing materials, and the AOG Drain Tank Room, by closing an existing valve.   This effectively removed the portion of the system within the excavated area from service. No steam or water is currently flowing through this drain pipe. Vermont Yankee said that it should be noted that there was no leakage from this pipe since the recent leak occurred and was terminated during the evening of May 28th. Conditions for the leak in the drain line to occur only exist for a short time during plant start up.  That is the reason leakage was not detected earlier during normal operation.Following isolation of the drain pipe, workers today are in the process of removing contaminated soil from the area.  Excavation is expected to be completed on Wednesday.  Groundwater samples taken at the nearby GZ-10 well on Sunday and Monday showed no detectable levels of tritium.The leak has been entered into Vermont Yankee s corrective action process which will determine the cause of the event and how it can be prevented in the future.last_img read more

Pertamina picks Siemens to supply machinery for Balikpapan refinery

first_imgThe new equipment “will enable a cost-effective expansion of the Balikpapan refinery and contribute to the success of Pertamina’s RDMP,” said Matthew Chinn, EVP of new equipment solutions for Siemens Energy oil and gas division, in the statement.The compressors will move gaseous substances, such as liquefied petroleum gas (LPG) and sulfur emissions, both of which are byproducts of oil refining, within the facility. Meanwhile, the electricity generation equipment will power internal operations.The installation and commissioning of the equipment is slated for 2022.The expansion of the Balikpapan refinery, with an estimated cost of US$5.3 billion, is slated to increase the facility’s production capacity by 40 percent to 360,000 barrels per day once fully upgraded in 2026, according to the RDMP.The project will also enable the refinery to produce high-quality fuel of the Euro V standard.Topics : Indonesian state-owned oil and gas giant Pertamina has chosen German engineering company Siemens to supply key machinery for its oil refinery in Balikpapan, East Kalimantan.Siemens will supply 17 gas compressors and ten pieces of electricity generation equipment, including gas turbines, steam turbines and a hot gas expander, to the refinery, according to a company statement from May 28.The move is part of Pertamina’s refinery development master plan (RDMP) to upgrade four refineries, including the one in Balikpapan, to help the oil company meet the country’s growing fuel demand without increasing fuel imports.last_img read more

AFC turned out to be the biggest hoax played on Guyana (Part 2)

first_imgDear Editor,Since the President is arrogating unto himself morality as the justification for his actions toward nomination of Public Officials, I find it instructive to examine the President’s actions with respect to the whole drug bond scenario.Dr George Norton, as Hon Minister of Public Health, lied to Parliament and was involved in a corrupt negotiation, and yet he is still fit and proper, intelligent, impartial, and with the integrity to run the Ministry of Social Cohesion. Former Acting Commissioner of Police Mr David Ramnarine was heavily criticised for transferring fallen Police officers, yet it is okay to transfer a corrupt Minister of Government to a new Ministry. Worse yet, Dr. George Norton is now the Vice-Chairman of the PNCR.Contrast the actions of Kamla Persaud-Bissessar, who fired eleven Ministers in four years while she was Prime Minister of Trinidad & Tobago.It has become clear that posturing by the President about ‘fit and proper’ and integrity and decency has no deep moral centre. It is all an act put on to penetrate the independence of the Guyana Public Service and to insert his choices into strategic positions.The AFC also asked the people of this nation to lynch the corrupt PPP officials, but forgive the AFC officials. We must still put our trust and faith in Nigel and Cathy Hughes after the entire Sithe-Global conflict of interest fiasco. I reiterate that double standards imply no standards.And this is a very sad situation for the People of this nation. A lot of us feel saddened, but we must arise from this depression.What we have in Government is a set of opportunists pursuing an agenda that the people of this country did not set. The single member of the administration who has voiced genuine concern for the wishes of the people is the Hon Jaipaul Sharma. The actions of this Government, including the breaches of the constitution, the contempt for the Carter Process, and recent calls for the National Assembly to appoint Commissioners, must be interpreted in the context of the double standards they have shown us. An alarm has been sounded throughout the nation. It has become clear to me that the citizens of this country have a problem of dictatorship on their hands, and the potential for electoral malpractice is evident.Can we, the citizens of this nation, do more than just shake our heads in disbelief at our unfortunate circumstances?As a child, I lived through the PNC dictatorship, and was at home hearing the wailing from the funeral procession of Dr Walter Rodney, who gave his life for this country. As a child, adults fought and paid with their lives for me to enjoy free and fair elections and an independent press. As an adult, I inherited a democracy that was hard earned. Now, as an adult, I am shocked to see a reversal and a callous trampling of the democratic values and practices that were so hard earned.Adults of today have a responsibility to create a stable political future, so that our children’s tomorrow may be free of this blight of dictatorship, corruption and political instability.While I was a graduate student at the Royal Holloway University in the UK, our backyard and playground were the fields of Runnymede, where the historic Magna Carta was sealed in 1215. We have inherited a British political infrastructure, but we did not endure the centuries-long struggle of the British people, nor have we endured the struggles of the American people for freedom. Let us be clear that our struggle is not one of PPP vs PNC politics. It is a relatively young struggle for a democratic political culture, an ideal that Government should be of the people, for the people and by the people.When we are governed by ideals, our politics can be graceful. Statesmen and women are elevated into politics by their virtues, not their greed and ambition and gerrymandering. Politics is an act of servant leadership, not to be engaged in for personal remuneration. While the politicians reveal to us daily who they are, we, the people of this country, must hold onto our centre and be the source of light in the darkness.Our struggle for democracy in this country continues, and as we stay calm and press on with it, when we feel afraid to voice our opinions and we feel oppressed by legislation, we must remember that people must not be afraid of their Governments, but Governments must be afraid of their people.Sincerely,Sandra Khanlast_img read more
