Cool. 

I'd never work for INPO--they don't pay well enough. And I always thought
they were much worse than the NRC. There's nothing quite like having your
own watchdog maul you worse than any burglar ever would. But I used to do
the cartoon in the back of Nuclear News magazine. I got $50 per issue.

Dear FOTers,

I have just returned from being down at the shore for two weeks, and
finally 
finished the lengthily tyre pressure seminar.  By now, it appears that all
of 
these tyres have finally gone flat.  These discussions gave me a partially

nostalgic feeling and a semi-sick feeling in the stomach.  My last
seventeen 
years out of thirty-seven years and ten months with Duquesne Light Company

were spent at the Beaver Valley Nuclear Plants.

My normal functions were to write the design concepts and installation 
specifications for many multimillion dollar heating, ventilating, air 
conditioning, and fire protection projects, plus coordinate the
construction 
activities concerning these projects.  Suddenly, I received the albatross
of 
being the chief Smoke Screen Calculation Generator Artist for the site.

The purpose of these calculations was to avert the NRC from imposing many 
more mega-million dollar modifications for HVAC and Fire Protection
Systems 
in vital areas containing safety related equipment.  Most were transient
heat 
transfer calculations to generate room heat-up curves in safety related
areas 
during accidents or loss of ventilation.  Others involved 
pressure/temperature transients in containment due to fires, pipe
ruptures, 
and loss of cooling.  

Eventually, the Analysis Group bought a Room Heat-up Program, and I
thought 
that I was done with these tasks.  Not so.  The Data Processing Group 
couldn't verify the program, and I was still into doing alternate 
calculations to verify those of the Analysis Group.  I tried to use a Math
- 
Cad program, but never was able to develop to a point where I could
rapidly 
flush away these tasks.

Soon, I was spending countless hours of overtime out of my life doing
these 
hand, incremental calculations (paid, of course or I wouldn't be doing).  
After several years of this, I felt like some long-haired Ph.D. would 
eventually come in with INPO and start discrediting some of these 
calculations.  Should this happen, the two 800 MW plants would be off the 
line.

That is exactly what happened, but this Ph.D. was bald.  He started
blasting 
away at a seven year old lengthily justification calculation that I did
for 
the Emergency Diesel Generator Building.  I had to recover this
calculation, 
take it home, and study it so that I could remember what I did.

Since I felt that I was reaching the end of my trail, I was determined to 
play the same game he was, and disagree with every objection he came out 
with.  He would receive answers such as he is entitled to his opinion, but
I 
am also entitled to mine.  I disagreed with what he was saying and give
him 
several reasons why.  He then wanted to see my 1958 Brown & Marco Heat 
Transfer Book, and that book suddenly got lost -- someone borrowed it two 
years ago and never returned it.

He then finds this ancient book in the University of Delaware Library and 
generates a document to discredit the calculation.  I counter with a
document 
disagreeing with all of the points he made, plus showed where he was dead 
wrong on some issues.  The throne people then got cold feet, felt that
this 
pi***** contest was going to attract the attention of the NCR, plus their 
hidden agenda of age discrimination might backfire.  The Ph.D. was quietly

funneled out the door.  To my surprise, I survived a couple more years and

left with their piddlely early out July 1, 1999.  Hi-Tech. Bill Babcock 
should be an INPO auditor.  He could have every Nuclear Plant in the
nation 
off the line, and generate six lifetimes worth of consulting work at
several 
hundred dollars per hour (supposed to be a joke).

About 20 some years ago, there was a group at Nelson Ledges who was doing 
tire pressure calculations for some reason.  I asked them at the time
about 
the moisture in their air tank.  Their answer was that they have a
moisture 
separator on their compressor, but they were still getting some moisture
into 
the tyres.

If I remember correctly, it was an 80 F day, and an average 30 F increases

was measured across the tyre width.  They started with 26 psi in the
tyres.  
I am now three years removed from these activities, and will probably make
an 
elementary mistake.  Larry Young already did something like this:

        PV = mRT        v = V / m       Pv = RT     R (air) = 53.35 ft -
lb / 
lbm - R

        P1 = (26 psi + 14.7 psi) X 144 psi / sq ft = 5860.8 lb / sq ft

        T1 = 80 F + 460 R = 540 R       

        v = RT / P = 53.35 ft - lb / lbm - R X 540 F / 5860.8 lb / sq ft =

4.916 cu ft / lbm

        T2 = 110 F + 460 R / F = 570 R

        P2 = RT / v = 53.35 X 570 / 4.916 = 6185.8 lb / sq ft

        6185.8 psf / 144 sq in/ sq ft = 43.0 psia - 14.7psi = 28.3 psi
tyre 
pressure

It seems that my tyres gain more pressure than this, but I am probably
using 
wetter more sloppy air.  I should buy another Sears moisture separator for

the compressor.  The bottom blew out of the one that I had, and the 
compressor ran several hours continuously before being discovered.

I think that I will just continue using the same most available gas, the
one 
that I have been using to gas-bag for so many years.  I will just continue

using my discarded empty 50 lb Refrigerant - 12 cylinder that I converted
to 
an air tank, and bleed and feed the tyres every time I go out onto the
track. 
 Big nitrogen cylinders are handy.  I have seen people running air tools
off 
of them.

Now it is time for me to go flat, and give the list a break.  Hopefully,
most 
of you will skip over most of the extraneous drabble.
