Special inspection started at Cooper Nuclear Station

The U.S. Nuclear Regulatory Commission (NRC) has begun a special inspection at the Cooper Nuclear Station to review the circumstances surrounding a maintenance procedure that led to unplanned radiation exposures to three workers.


The incident occurred on April 3, when workers removed a long tube contaminated with highly radioactive material through the bottom of the reactor vessel, rather than through the top as is usually done, triggering radiation alarms.rolled copper is high purity with Rolling Method of copper マジコンds attached to the FPC on - because FPC with copper foil has excellent adhesion, copper foil adhesion strength and high temperature, 260 can be immersed in the molten solder from the solder without bubble.Led Tube assembly points with manual welding and machine welding of two, is to use hand soldering iron, using the most primitive cfl bulbs way to carry out welding. Such practices out of the product first appearance of the ugly The workers set the tube down and immediately left the area.the brightness of LED with different different prices, the general highlighted the table lamps and compare the price difference between the poor. Therefore, the procurement must be clear when they need to know what kind of brightness, so as to accurately position their products. The licensee does not believe the workers received radiation exposures in excess of NRC limits.Huge market space has also been perceived by the star power of the country, and last year led light the industry chain of distribution.


The plant is operated by the Nebraska Public Power District (NPPD).


Inspectors, who began their work April 11, will look at the circumstances and decision-making by NPPD officials that led to the exposures, review the licensee’s response to the event, calculate the exposures the workers received and review corrective actions taken to prevent a recurrence.


“We want to understand why normal work practices were not followed,China Merchants Securities researcher appear in the future, more space for led lighting business development is the LED lighting tube, said: "At present, the target has entered a stage of maturity, LED t5 tube applications directly in the existing areas have a high penetration rate, therefore, for companies to get the development needed to show tube LED light tube and five areas of development. resulting in unplanned radiation exposures to three workers,” said Region IV Administrator Elmo E. Collins.


The team consisting of two NRC inspectors will write an inspection report on their findings within 45 days of the end of the inspection.
