Transcript of Ethical Disasters

Background
A series of pumps feeding water to the steam generators at reactor 2 failed
This causes a temperature and pressure increase in the reactor

As designed, a relief valve opens draining water from the reactor core
This causes a sudden pressure drop

Emergency coolant is pumped into the reactor

Failing to notice the relief valve is stuck open, an operator shuts down one of the emergency coolant pumps

After 2 hours and 22 minutes the backup relief valve is shut
Background Cont'd
Ethics
Communication Failure

Operators were not properly trained
Management communication process had three basic problems
The lines of communication did not compliment the decision making process
The procedures did not provide for effective feedback
The procedures often were quite informal
One of the engineers also gave false information to the public

The Disaster
February 7, 2014 General Motors recalled about 800,000 small cars due to faulty ignition switches.
The design of the GM ignition switch caused recalls that range from
1997
to
2014
.

Recalls on the ignition switch started in February of this year, but the defect was known many years beforehand.

Engineer
DeGiorgio
redesigned the Cobalt ignition switch in 2006, without documenting the change. This shows the defect was known in the Cobalt at least
8
years prior to the recall.

Emails exchanged with the supplier from DeGiorgio revealed
no
mention of
safety
concerns regarding the updated ignition switch.

While under testing,
engineers
hit the key ring with their knee and it moved to accessory position, stalling the car. The "...incident was categorized as an annoyance rather than a safety issue."
GM CEO Ms. Barra confirms this during ECC hearing.
Ethics
"GM engineers knew about the defect. GM investigators knew about the defect. GM lawyers knew about the defect. But GM did not act to protect Americans from defect."
~David Friedman
NHTSA Administrator

High cost of repair outweighed customer safety
Lead to the death of at least 13 people
Undergoing multiple lawsuits for families of victims
This scandal caused a major decline in the public's view of General Motors.

It is believed that this faulty design was approved in 2002 even though they did not meet the safety standards.

From the presented information, due to General Motors knowledge about the faulty ignition design 10 years prior to a recall, causing several fatalities, and giving false testimony it was determined that this Ignition failure is the most important ethical disaster.

A lack of coolant caused a partial meltdown of the core
This created a toxic hydrogen bubble that eventually exploded

Due to damage the reactor was permanently shutdown



This incident solidified the public's opinion against nuclear power

No new reactors have been built in the US since the incident

Though minimal, the disaster caused some contamination of the surrounding area
