Southern California Edison Continues Practice of Upgrading Key Components of the San Onofre Nuclear Generating Station via Market Watch

Two new technologies to be installed during 2012 will enhance plant safety and power affordability

ROSEMEAD, Calif., Jan 10, 2012 (BUSINESS WIRE) — Southern California Edison (SCE) temporarily removed from service yesterday one of the two large generating units at its San Onofre Nuclear Generating Station — Unit 2 — for a scheduled refueling and maintenance outage. During the outage SCE will continue its practice of upgrading plant hardware and systems when it is possible to enhance the safety, reliability or customer cost-effectiveness of the plan

Since the last Unit 2 outage concluded April 11, 2010, the 1,100-megawatt generator has provided utility customers with power 24/7, with the exception of a precautionary three-day shutdown in September 2011 a grid disturbance caused. During this latest 21-month run the unit has contributed more than 16 billion kilowatt-hours to customer electricity needs. Nineteen percent of all power Edison customers use comes from nuclear generation.

Plans for the outage, and a similar Unit 3 outage scheduled for this fall, include replacing the reactor heads of both units and retrofitting the high pressure turbines with new rotating and static components.

    This article explains that we can improve the safety of nuclear plant and it is not expensive to upgrade equipments.We should make effort to check safeness of nuclear power plants studying from Fukushima’s accident.The cost of operating nuclear power plant is cheaper than other plants and maintenance is also not expensive.We should continue to invest on nuclear technology because we shoud not forget global warming problem.Nuclear energy and renewable energy are both important for our future.
