Vermont Yankee reports that engineers and technicians continue their investigation into the source of tritium in the plant’s groundwater and have commenced soil and groundwater remediation planning. Tritium, a radioactive isotope of hydrogen associated with nuclear fission, was first identified in a test well at the nuclear power plant in Vernon in January.According to a Vermont Yankee statement, sample results from all the monitoring wells remain consistent with inspectors’ expectations and increased understanding of the movement of groundwater in the Advanced Off Gas courtyard. The information being provided is helping hydrologists to characterize the tritium concentration in that area and is assisting engineers in developing plans for remediation work. Upcoming near term activities include taking additional soil samples in the area near the previously identified leakage pathway and the use of guided wave technology to confirm the integrity of other hard to reach piping systems.According to a Vermont Yankee statement, the temporary piping modification involving the rerouting of the two drainlines to eliminate the leak pathway from the AOG drainlines into the tunnel is in progress. The rerouting of the Bravo ‘B’ drainline will be completed today, allowing the switchover from the ‘A” train to the ‘B’ AOG recombiner train. ROV camera inspections of the tunnel will be conducted at that time, followed by the rerouting of the ‘A” drainline. The rerouting work is scheduled to be completed later in the week. This leak in the AOG tunnel is being collected in a sump for processing through plant systems as designed. It is not reaching the environment.While this investigation continues, it is important to note that there has been no detectable tritium levels found in any samples taken from drinking water wells or the adjacent Connecticut River. The Vermont Department of Health and Nuclear Regulatory Commission personnel are monitoring the investigation.Source: Entergy Vermont Yankee. 3.16.2010
New Delhi: BCCI’s North Zone curator Sunil Chauhan overwatered the Feroz Shah Kotla pitch and then, breaching protocol, left the venue before the start of Delhi-Madhya Pradesh Ranji Trophy match on Saturday, his indiscretion leading to a delay of two and half hours. Despite perfect weather conditions, the match began in the second session. While the hosts reduced MP to 132 for nine courtesy left-arm spinner Vikas Mishra’s 6/41 in 18 overs, the delay in proceedings could land the Himachal Pradesh curator in trouble.Off-spinner Shivam Sharma got 3/48 on a pitch where the ball kept low, but there was some turn on offer, with the odd ball taking off from the spot. As per BCCI rules, the neutral curators are sent to prepare pitches so that home teams cannot take any advantage, and they are only supposed to leave after lunch on the first day, when local curator takes charge.On Saturday, much to the dismay of the Delhi team, match referee Daniel Manohar (former Hyderabad batsman) and the two umpires Virender Sharma and Sanjay Hazare found out that the pitch was wet and under no circumstances could start the game as scheduled at 9.30 am.It was then realised that the Dharamsala-based curator Chauhan, who was in charge of preparing the strip, had watered it the previous evening.”Under Sunil Chauhan’s instructions, the pitch was watered on Friday evening. He himself is from Dharamsala and knows the weather conditions in Northern India inside out. The pitch was watered around 4 pm and naturally it was cold and moist with little sunshine,” a senior DDCA official, privy to the development, told PTI.When the match officials came to the ground in the morning, as per BCCI rules, Chauhan was supposed to be present for the handover of the ground to the match referee. He was nowhere to be seen, though.”Chauhan had to stay back till first-day lunch which is the common rule for all neutral curator before the local curator takes over. He left and then our curator Ankit Datta had to get the ground ready along with outsourced groundsmen as the regular groundsmen have gone on strike,” the official said.Chauhan couldn’t be reached for comment. However, BCCI GM (Cricket Operations) Saba Karim admitted that the situation could have been avoided and he has sought a report from Chauhan.”I agree that what happened at the Kotla today shouldn’t have happened but I believe Mr Chauhan must have had some compelling reasons to have left early. He took a 10 am flight from Delhi. Normally, he has never done that, so I would like to believe that there is some reason behind it. We will find out,” Karim told PTI.
