CRANBERRY TWP — Westinghouse Electric reportedly plans to cut 665 jobs from its global work force because of a decrease in demand for nuclear power reactors.

It it unclear how many employees would be affected at the Cranberry Township campus, where more than 4,300 people work.

The company plans to cut about 5 percent of its work force. Senior management reportedly notified employees Wednesday of the plans.

Westinghouse employs more than 13,000 people worldwide.

The company has been forced to re-evaluate its business strategies in the wake of the global recession and the effects of a reduced worldwide demand for nuclear energy after a nuclear plant was damaged in Japan.

The cutbacks reportedly include open positions that have not been filled.

This news comes less than a year after the company eliminated about 200 jobs in a round of voluntary separations and layoffs. The positions eliminated last May came in departments not directly related to engineering or nuclear energy.

Westinghouse moved its corporate headquarters to Cranberry Township in 2009 and began a hiring spree in anticipation of increased demand for nuclear power.

The company hired about 5,000 employees in the past several years.

It is currently building four Westinghouse AP1000 nuclear power plant units in China as well as the four AP1000 units in Georgia and South Carolina. Those are the first new nuclear power plants to be built in the United States in more than a generation.
