[C Czajkowski; Brookhaven National Laboratory.; U.S. Nuclear Regulatory Commission. Region II.; U.S. Nuclear Regulatory Commission.

Office of. A metallurgical failure analysis was performed on pieces from a catastrophically failed inch diameter feedwater from the Surry Unit 2 Nuclear Power Station.

The analysis consisted of optical microscopy, chemical analysis, mechanical and Charpy impact testing and evaluation of the material by scanning electron microscopy. Evaluation of flow accelerated corrosion by coupled analysis of corrosion and flow dynamics. Relationship of oxide film thickness, hematite/magnetite ratio, ECP and wall thinning rate.

CO_2 sequestration in ocean, i.e. transportation of liquefied CO_2 removed from flue gas at fossil-fuel-fired power plants through a pipe into the ocean, is considered to be an effective. Based on the operating experience of Surry Unit 2, Maanshan Unit 2 reduced the power to 97% of nominal power in late Novemberand further reduced it to 95% in March Unit 2 started its 15th refueling outage on 12 April, when SG chemical cleaning was carried out.

After this chemical cleaning, the water oscillations by: 5. Full text of "TITLE LIST OF DOCUMENTS MADE PUBLICLY AVAILABLE VOL 2 NO12" See other formats.
