Henry West's Commentary on "Dissent about Nuclear Safety"
I
Whether Alison Turner should express her reservations
depends upon several factors. Some of the issues are technical.
Some involve the importance of particular safety regulations.
Also involved is the power structure of the company and perhaps
her judgment of the motives and scruples of higher
management.
Apparently she is uncomfortable with the assumption that the
heat exchangers have 95% of capacity. How implausible does she
think this estimate is and how far off? If she believes that
this is probably an unrealistic estimate, made in good faith
but probably an overestimation, does she have any good grounds
for challenging its accuracy? And what would be the result if
it were revised? If she believes that it is a deliberately
false estimate, made to get approval of continued operation,
she is up against a potentially more difficult situation.
Whichever it is, there is also the question of the danger in
case of an accident resulting in the loss of one heat
exchanger. Alison thinks that this should be considered in the
report. In such an event, would the result probably be
catastrophic, or merely require quicker action to shut down
operations?
Sometimes regulations are excessive. Does she believe that
the regulations are excessively cautious or does she think that
they are appropriate? If Alison personally believes that they
are excessive, does that make a difference? If Alison thinks
that there is a real danger, she has more obligation to express
her reservations than if she thinks that the Single Failure
Criteria are excessive, doesn't she? Or is her personal
judgment irrelevant? Think about it from another point of view.
Would you want the members of the Plant Nuclear Safety Review
Committee using their personal judgment about the importance of
the safety regulations in situations like this, or should they
conform to the letter of the regulations?
In this case, the requirement that the plant anticipate loss
of one heat exchanger in the event of a possible accident is
being overlooked, rather than being violated, in the JCO. Is it
up to the NRC to notice that? Or is it the responsibility of
the plant to meet the requirement? If I am applying for a job
and I leave blank some of the questions when answers would call
attention to my weaknesses, isn't it up to the employer to
decide whether to ask for further information? Is there any
analogy between these two situations?
Alison is the least senior member of the committee, but she
is still a member. If she is unable or unwilling to voice her
opinion, she might as well not be there. Voicing a reservation
is doing no more than expressing a professional judgment. But
it is at the same time challenging the work of those who
prepared the JCO and challenging the judgment of her superiors
who see nothing wrong with it. That may take courage.
What if Allison thinks that the 95% capacity is a
deliberately false assumption, made up to have a satisfactory
JCO and avoid shutdown? Does that make any difference? In that
case she would seem to have an additional responsibility to
speak up, since in that case her superiors do think that there
is something wrong with the JCO and are not saying so. But that
may take even more courage, since she is not just raising a
technical question but, at least in her own mind, questioning
their integrity.
If the problem is sand blockage on the lake water side, is
that something that will be remedied while the plant is
operating, and will it be remedied if the JCO is approved? Or
is the sand blockage something that is going to get worse and
make the heat exchangers less effective as time goes by? If so,
will the plant become progressively unsafe, or will the problem
eventually require shutdown to remedy it? If so, wouldn't it be
better to do it sooner, rather than later?
II
Not much has changed as a result of the discussion after
Alison expressed her reservations. One member of the committee
supported her concern and pointed out that it would take only
three hours to carry out the calculations. That this trouble
wasn't taken might make her even more suspicious that there is
a deliberate effort to submit a misleading JCO. If so, she
would have even stronger reason to cast a dissenting vote, for
she would feel that there was more than just a matter of
technical differences of opinion. On the other hand, she may
have been persuaded by the argument that other plants are
operating without containment spray systems; therefore it is an
unnecessary extra precaution. She could even believe both--that
there is only a very remote risk of its ever being needed and
of its being unnecessary if it is, but also that management is
deliberately ignoring the problem.
III
She might have been right to have expressed and voted her
reservations, even if they turned out to have been unwarranted.
She showed honesty and integrity. But she may have also
adversely affected her career. Not to have unanimity on
approval of a JCO is probably not appreciated by the company.
It does not look good. To challenge the judgment of her
superiors may not make her a welcome member of the team, and
the fact that her concerns were unwarranted could be used
against her. Is that something that she should have worried
about when voting?
On the other hand, expressing and voting her honest opinion
may be regarded as a virtue by her superiors. Which do you
think is more likely? If you were the superior, which kind of
subordinate would you want? If you were an owner of a company
or the public affected by decisions, which kind of superior
would you want?
In all of this, does it make any difference that Judy is
female? Is it more difficult for her to express her judgment
because of her gender?
