Davis-Besse Containment Pressure Test Under Way
2003-04-08 13:53 ET - News Release
April 8 /PRNewswire-FirstCall/ -- FirstEnergy Nuclear
Operating Company (FENOC) announced today the initiation of
another important milestone in the restart process at the
Davis-Besse Nuclear Power Station -- a pressure test of the
1-1/2-inch thick steel vessel inside of the containment
The test, called an integrated leak rate test, began late
yesterday and is expected to be completed by the end of the
week. It is required by Nuclear Regulatory Commission every 10
years, and was successfully performed at Davis- Besse in 2000.
However, because crews opened the containment building to
replace the reactor head last summer, the test is being
repeated now to verify the restoration of the structure.
The test is designed to verify the integrity of the
containment vessel, which measures 285-feet high and 130-feet
in diameter. The 2.8 million cubic feet of the containment
vessel houses the reactor and important safety equipment. The
leak rate test requires increasing the normal atmospheric
pressure inside containment to 38.5 pounds per cubic inch,
maintaining that pressure for about six hours, and using
instrumentation to verify the pressure.
"By the end of the week, we'll add this test to a long list
of important milestones we've reached on our way to restarting
this plant," said FENOC Chief Operating Officer and Site Vice
President Lew Myers. "We're making good progress, completing
more than 5,000 work activities since the first of the
Those activities include: the design and installation of a
permanent reactor cavity seal; completion of the integrated
Safety Features Actuation System test, which checks most of
the important safety systems in the plant; modification of the
emergency containment sump; and installation of the FLUS Leak
Detection System on the bottom of the reactor vessel -- the
first time this state-of-the-art system has been used in a
U.S. nuclear power plant.

the Akron, Ohio- based FirstEnergy Corp. , a registered public
