Tokyo Electric Power Company, Incorporated , also known as Toden or TEPCO, is a Japanese electric utility servicing Japan's Kantō region, Yamanashi Prefecture, and the eastern portion of Shizuoka Prefecture. This area includes Tokyo. Its headquarters are located in Uchisaiwaicho, Chiyoda, Tokyo, and international branch offices exist in Washington, D.C., and London. It is a founding member of strategic consortiums related to energy innovation and research; such as JINED, INCJ and MAI.In 2007, TEPCO was forced to shut the Kashiwazaki-Kariwa Nuclear Power Plant after the Niigata-Chuetsu-Oki Earthquake. That year it posted its first loss in 28 years. Corporate losses continued until the plant reopened in 2009. Following the March 2011 Tōhoku earthquake and tsunami, its power plant at Fukushima Daiichi was the site of a continuing nuclear disaster, one of the world's most serious. TEPCO could face ¥2 trillion in special losses in the current business year to March 2012, and the Japanese government plans to put TEPCO under effective state control to guarantee compensation payments to the people affected by the accident. The Fukushima disaster displaced 50,000 households in the evacuation zone because of leaks of radioactive materials into the air, soil and sea.In July 2012 TEPCO received ¥1 trillion from the Japanese government. TEPCO's management subsequently made a proposal to its shareholders for the company to be part-nationalized. The total cost of the disaster was estimated at $100bn in May 2012. Wikipedia.

A facility maintenance method updates, in a case where an event having occurred in a facility is determined to fall outside a fault tree, the fault tree such that a cause of occurrence of the event identified through investigation is reflected, and in response to the identified cause of occurrence of the event, identifies a location where a structural element of equipment/material identified to relate to the cause of occurrence of the event is used, based on installation information indicating a location where the equipment/material is installed, to formulate an inspection plan for the identified location.


A method is used for determining reusability. The method includes receiving image data of a boundary sample and repairing method data corresponding to the image data from a database using a terminal; outputting the image data of the boundary sample for each reuse form of the device and the repairing method data using an output device; and determining whether to repair and reuse a used device by comparing a state of the recovered device with the output image of the boundary sample.


An area characteristic display device includes an inputter which receives input of information that enables identification of state and position of equipment installed outdoors, and a display controller which displays, based on the information that enables identification of the state and position that has been input to the inputter, and data on area characteristics, a distribution of the state together with the data on area characteristics, on a display with being superimposed on a map.

An information processing system includes an information acquisitor, a screen information generator, and a display controller. The information acquisitor acquires, from history information including at least information indicating a moving route between electric facilities uncharted on a map and utilized in past, information indicating a moving route utilized at the time of moving from a first electric facility to a second electric facility based on information indicating the first electric facility out of a plurality of electric facilities and information indicating the second electric facility connected to the first electric facility by a connection line. The screen information generator generates display screen information to generate a display screen based on the information acquired by the information acquisitor and indicating the moving route. The display controller displays the display screen on a display of the information processing terminal based on the display screen information generated by the screen information generator.


A method for measuring a deflection amount of a columnar structure includes the following steps. The method includes placing a longitudinal direction of a columnar structure in a direction parallel to a ground to place the columnar structure on a support member that supports the columnar structure such that the columnar structure is rotatable around an axis in the longitudinal direction; determining that the columnar structure placed has stopped rotating under its own weight around the axis; and measuring, after the stop of the rotation is determined, measuring a distance in a vertical direction between a straight line connecting both ends in the longitudinal direction of the columnar structure and a curved line along a shape in the longitudinal direction of the columnar structure.


A method is used for selecting a boundary sample. The method includes acquiring a deterioration trend of a new device by performing a deterioration acceleration treatment to the new device, acquiring deterioration trends of a plurality of repaired devices which have been repaired after long-term use by performing a deterioration acceleration treatment to the plurality of repaired devices, calculating an upper limit of deterioration of the repaired device based on the deterioration trend of the new device, and selecting a boundary sample indicating a limit state in which the device can be reused as a standard of reuse of the device by specifying a repaired device having the largest deterioration among the repaired devices having a deterioration not larger than the upper limit.


A facility state analysis device of an embodiment is provided. The device includes an inputter which accepts input of information specifying a state and location of a facility installed outdoors, a calculator which calculates, by performing statistical processing based at least in part on the information specifying the state and location input to the inputter and information on a predetermined section on a map, an average failure year of the facilities in the section, and a display controller which displays, on a display, the average failure year calculated by the calculator superimposed on the map.
