00:03.579 --> 00:05.801
One of the final steps in the refueling

00:05.801 --> 00:07.968
process involves removing fuel from an

00:07.968 --> 00:10.135
area called the flowable tank bottom .

00:10.135 --> 00:12.357
In Red Hill's case , removing fuel from

00:12.357 --> 00:14.523
the flowable tank bottom refers to the

00:14.523 --> 00:16.523
process of extracting fuel from the

00:16.523 --> 00:18.468
last 10 ft of each tank tanks that

00:18.468 --> 00:22.129
stand 250 ft tall above the 10 ft level .

00:22.139 --> 00:24.360
Main fuel lines can utilize gravity to

00:24.370 --> 00:26.314
remove most of the fuel below this

00:26.314 --> 00:28.481
level . However , a smaller drain line

00:28.481 --> 00:30.759
at the bottom of each tank is utilized .

00:31.200 --> 00:33.930
Red Hill has 14 active fuel tanks with

00:33.939 --> 00:36.106
each floor tank bottom holding roughly

00:36.106 --> 00:39.259
120,000 gallons of fuel . Each floor

00:39.310 --> 00:41.680
tank bottom is expected to take 14

00:41.689 --> 00:42.930
hours to Deuel .
