“I’m trying to leave you with the idea that everything the crew needs to survive, they’re in good shape. All their systems are active and what we’re talking about really, it would be a significant challenge if we suffer the next failure but it’s not normal because we can’t do normal operations with these power downs and the fact that we need to get on with the EVA (Extra Vehicular Activity).”

7. SOUNDBITE (English) Mike Suffredini, NASA space station programme manager:
“From a failure standpoint, it’s early. On a whole, from the ISS standpoint, we have been much, much, more reliable in our systems than we had expected. While you have design lives for many, many years, when you look at your mean time between failures, you build a sparing philosophy based on your mean time between failures, and life if your design life is less than the design life of the system and so we spared that way, but this is a little bit earlier than we expected on the pump.”

“This is an anomaly we knew someday would happen, it’s an anomaly that we have trained for, it’s an anomaly that we have planned for. Obviously we’ve spared for it. We’re in a good position to go solve this problem. It is a significant failure, though, in terms of systems on board ISS, so it’s one we need to go get after.”

Astronauts in orbit and on the ground practiced on Monday for a major repair job later this week at the International Space Station.
A weekend malfunction knocked out half of the space station’s cooling system, forcing the crew of six to turn off unnecessary equipment and halt scientific work to avoid any overheating.
NASA’s space station programme manager, Mike Suffredini, ranked the problem as one of the most serious in the 12-year history of the orbiting lab, but stressed the outpost could keep going indefinitely given the current situation.
The fear is that the second cooling loop could shut down at any moment and leave the station in precarious shape.
For now, “everything the crew needs to survive, they’re in good shape, all those systems are active,” Suffredini told reporters on Monday.
“What we’re talking about really, it would be a significant challenge if we suffer the next failure,” he said.
Two of the Americans on board – Douglas Wheelock and Tracy Caldwell Dyson – will venture out on a space walk to replace the pump on Thursday.
A second space walk will be needed to finish the job, most likely on Sunday.
The 780-pound (350-kilogram) pump is difficult to handle, and the astronauts will need to guard against any hazardous ammonia leaks.
Engineering teams have been working non-stop since the right-side cooling loop shut down on Saturday night.
A pump that drives ammonia coolant through those lines failed when a circuit breaker tripped.
The disabled pump has been at the space station since 2002 and operating fully since just 2006 and this was a premature failure.

Reconditioned Circuit Breakers
The HKD3400F Circuit Breaker has been reconditioned per MIDWEST’s
rigorous service procedures based on 30 years experience. The HKD3400F
circuit breaker has been maintained and refurbished per industry
standards and per MIDWEST’s Quality Control Program (QCP). The services
include applicable internal and external procedures, repairs, and
replacement of deficient components. In addition to standard electrical
tests, MIDWEST also performs live function tests on the HKD3400F. These
services far exceed the routine reconditioning of the HKD3400F
performed by many circuit breaker vendors and resellers. MIDWEST
certifies the HKD3400F circuit breaker has passed our QCP before
New Surplus Circuit Breakers
A “New Surplus” Circuit Breaker is a circuit breaker that has never
been installed, but is not “New from the Factory” or “New from the
Manufacturer or Distributor” of the HKD3400F circuit breaker. It may be
referred to as New in the Box, New Surplus, Never Installed, Never
Energized, or other such term that avoids the label “New from the
Manufacturer.” A New Surplus HKD3400F circuit breaker should not be
considered new from the manufacturer or manufacturer’s Distributor.
Surplus and New Surplus HKD3400F circuit breakers must pass MIDWEST’s
(QCP) Quality Control Program.
