You dammed nukes are strange

image of odd looking sailor

I do not need to tell anyone reading this posting that used to be nukes attending nuke school and completing at least one tour of duty at sea can change a person forever.

Many guys before they become nukes are bright, part of the reason they were able to do well enough on their ASVAB to qualify to go nuke but happened to be bit unfocused and unmotivated which resulted life results, in a lot of ways, below their true ability.  Later in life many seemed to get things going in the right direction and amounted to productive lives either after doing a tour and returning to the civilian sector. Perhaps the required mandatory”tac” hours during nuclear power school provided some benefit. O.K., I would not go that far but I will l say the structure has aided in creating many successful ex-nukes.

More specifically, I have picked up subtle habits from my time as a nuke I still do to this day. For example, I still fold my skivvies; I mean underwear, in the same fashion I learned in boot camp. Why you ask? Honestly, I never had the motivation to come up with a better way of doing it.  

Another skill I acquired which is a bit more useful than folding underwear is the ability to be able to look through large documents like reactor plant manuals and find the one paragraph or sentence of valuable information within a very short amount of time.  

Another habit a number of my shipmates picked up was smoking cigarettes and chewing dip. In the long term the detrimental health effects cannot be questioned but after the first few weeks of a long deployment at sea who wouldn’t need a little bit of nicotine to help get them through. Now if they could quit.

Are there any strange habits you picked up from your time as a nuke?

Why is it so quiet topside?

I recall an instance before my first Westpac while I cranked, as almost every did before he qualified any watch stations and made some use of himself. A few days after throwing off the mooring lines off in Pearl Harbor we pulled into Ketchikan, Alaska to pick up supplies if I remember correctly.

Once we moored a few of the guys went up topside to take a glance at our surroundings and for some unexplained reason no one said a word once they climbed up the hatch and walked around.

Normally when we pulled into port after being underway everyone is hooting and hollering in excitement to get a bit of fresh air which most people take for granted. I finally went up topside in my tee shirt in the 50 degree weather and see for myself.

After gathering my thoughts for a minute I tool notes of the fact I have never seen anything so awe inspiringly beautiful in my entire life - the water was clear enough so the reflection of the boat looked as clear as a mirror. Additionally, tall pine trees covered the whole valley even down to the water’s edge which were complemented by snow capped mountains in the background.

As everyone took in the scenery no one said a word, there was no need to. If someone had I am sure it would not have adequate described our thoughts on what we were observing.

This came as a surprise to you as most military guys are not what you would characterize as "tree huggers" but maybe one shouldn't need to be, we are human after all with some appreciation of nature. Later the boat pulled in British Columbia noted the provinces license plate which stated "Beautiful British Columbia". The beautiful backdrop we viewed in Alaska characterized the type of scene which spawned the slogan, granted we had left Alaska and went to Canada but this was close enough to get the idea.

Any moments in your time as a nuke which impressed you in a way you might not feel comfortable sharing with your buddies on the mid-watch for fear of ridicule?  Let's hear your story and you do not need to leave your name...

What do you want the chemistry to be?

Image on Chemical mixing paddle

                I was standing Reactor Operator and the watch section ELT came into maneuvering with the latest steam generator results. The EOOW asked, "What does the chemistry look like" to which the ELT replied, "What do you want the numbers to be?"

                Looking in back in retrospect my thought is, "Why did it need to anything at all?" If the government can design a nuclear reactor and primary coolant system to live through the 30 year life of a submarine why couldn’t a steam generator be designed which didn't need to be baby-sat while steaming?

                I am sure, in theory, the possibility exists, in the same way you could believe your experience in A school and Power School would be reflection of what your life was going to be like once you arrived on your boat as a nub.

                The sad fact is water which goes into a steam generator which eventually becomes steam which propels the boat and provides electricity contains crap which over time can damage the S/G which would prevent a boat from going underway. As a sailor we would not want that would we?

                In case you cared, water is the essential medium for steam generation and conditioning it properly can increase the efficiency of boiler and as well as extend its life. The treatment of boiler water also insures safe and reliable operation: without proper treatment, severe problems can develop, some so severe the Steam generator itself may need to be replaced.

                Aboard ship, fresh water is obtained by distilling seawater in evaporators. The portion of the distillate which is set aside for use in the boilers is known as make-up feed-water. The water used within the boiler is called boiler water. Make-up feed-water should be pure distilled water in an ideal situation but as stated earlier it will contain some amount of foreign materials which includes Magnesium and Calcium.

               Those of us who really dig this stuff remember the three types of water treatment in a boiler system: 1. Blowdown, which maintains the TDS (total dissolved solids) in the system (one of my favorite duties as a Reactor Technician) 2. External Treatment, which removes hard salts, minerals and oxygen before the water enters the boiler and 3 Internal Treatment, which maintains proper water chemistry by adding chemical additives to the boiler water. (Thanks to ELT's)

                This knowledge is all wonderful after EAOS if you planned to work with generators/boilers as a civilian. I was surprised to learn long after I left the Nuclear Navy there are civilian boiler technicians who were involved many of same principles ELT worked.

               Which leads me to the question: Any ex-ELT who has worked with steam generator/boiler after they got out? "What did they need their chemistry to be?"

The meaning of Power in Nuclear Power

Image of danger sign outside high power facility

Can you sketch the EPCP? Come on you remember; I’ll help you, draw a Turbine generator on port, now another turbine generator on starboard, a tie bus, and Motor Generator. Where do I draw the battery well?

Alright, I’ll stop the correct drawing of the EPCP is not really crucial. Here is what is important: the experience and knowledge you gain in power plants during your nuclear career can be useful in ways which might not be as obvious.

Let me put the idea this way, in the past ex nukes explored opportunities in Nuclear Power once they left the nuclear navy. Over the years after Chernobyl and Three Miles Island accidents and again recently in light of the Japanese Tsunami the nuclear segment have downplayed the possible careers in this field.   

What about the power portion? The power portion will be alive and well due to the simple fact in order to maintain a modern society the power must stay on and trained technicians and engineers will be needed to order to make this a reality. That is where you the ex- nuke comes in.

Therefore, there are bound to be opportunities for those who enter the civilian world knowing how a high voltage power system works.  Now there’s an efficient use of the time spent standing watch.

Women selected for submarine training – Should they get a boat with their own crew?

 Officer submarine candidate

The excerpt from Al L. below was sent to ExNavyNuke.com to post and garner thoughts from the viewers of this blog. 

Eight women selected for submarine training. ONLY of the officer class.

I am trying to get input from as many persons possible on this topic, an Idea of mine.

What is the feasibility of a nuclear sub crew, a sub say of the Virginia class, crewed solely by women, from the commander down to the lowest ranking "seaman"?

Obviously, any concerns about bunking, separate showers, toilets, etc., would no longer exist with an all-female crew.

And the women could do the job, this is do-able? Strength is not an issue, skill is the issue and women are more than competent enough.

The only strength issue might be re-loading the torpedo tubes, and for some time has been done by hoist and mechanical apparatus. Perhaps damage control in time of emergency might require strength?

Any other issues anyone can think of?

Al L.

ExNavyNuke.com thoughts: In my view I think it might work. During my time in boot camp at Orlando Training Center before it was closed down the “K” (all female) companies who went though basic training crushed all of the “C” (all male) and I (Integrated) companies they competed with in regards to inspections, academics, etc. I am sure this efficiency could be duplicated aboard a submarine.

Drills for the worst case scenario

Image of vest used for drill monitors

I recall from my time as nuke doing drills in preparation for Occupational Reactor Safety Exam. (ORSE) These drill sets by and large featured events on the reactor plant which would never happen in real life.

For example, given the design factor of all the materials designed into anything associated with nuke outside of getting hit with a Russian torpedo in the sea of Okhotsk what are the odds of flooding in engine room lower level (ERLL), Reactor Scram, and High Steam Generator chlorides all in the space of one hour. 

Eventually after enough training, debriefs and, in some cases, critiques when one of these casualties occurs underway performing the initial and supplemental action seem pretty routine.  

The reason I mention this is many people feel in the aftermath of the Japan disaster the country was unprepared. Recalling what transpired which included one of the strongest Earthquakes in recorded history, its ensuing tsunami, and lastly the trouble with their nuclear facilities to due to losing the ability to cool the reactor which resulted from the loss of power and infrastructure to operate the plant in a safe manner.

If the Japanese would have drilled against this doomsday scenario in a fashion to our nuclear training would it made a difference?? No one knows. My only wish is that we did not need to ask the question.

Eli the Ice Man, glad I remembered you

Image of a small inductor coil 

One can never be sure of the moment where something you learned in nuke school pops into your head at the strangest time.

Most of us are aware much of the information covered in training will not be applicable after your nuke days are finished. There are exceptions, my moment occurred during a job interview where the interviewer asked me the difference between Kilowatts (KW) and Kilo Volts Amperes (KVA). By the way, if you wondering my interview was for a sales engineer position.

I remembered kilowatts were units of power which were equal the product of voltage and current. As for the question posed I knew the relation of KW and KVA had something to do with the lag of the current due to the inductive portion of the current.

Then the phrase, "Eli the Ice-man", came back to me in an instant which I had not thought about since I completed Nuclear Field “A” school over 15 years ago in Orlando, Florida.

With this I composed myself and explained how current lags voltage in an inductive circuit as a result of the time required to generate its magnetic field and how kilowatts expressed the power available to do work and KVA measured the induction component of the power.

The interviewer seemed impressed since I do not hold a B.S. in Electrical Engineering. I still do not understand why I was able to recall Eli during a pressured situation. I guess I should give props to the Navy’s training as painful as it could be at times. Have you ever had a moment like this as an Ex Nuke??

Electrical Operator, “Shift the electric plant to Normal Full Power Line Up”

Image of a Syncroscope

For all of you electrical operators out there does this scenario sound familiar? You are in a half power lineup on the port turbine generator.  The Starboard Turbine Generator (TG)is ready to go and you need to bring the TG on the bus restoring the plant to a NFPL and restore the ability the answer bells on both main engines. You know the drill.

What are the things which must occur before you shut a breaker?  For starters the voltage and frequencies of the incoming load and the running bus must match and the synchroscope needs to rotating clockwise prior to shutting the breaker within the gray area at the 12 o clock position on the gauge. Do you remember why? In short, varying frequencies on the generator could speed up or slow down causing damage or excessive power transients. Likewise a variance in voltages can result in transients as well. Proper shutting of the breaker using the synchroscopes ensures the two buses are on phase in addition to ensure the incoming bus picks up the load. 

In any case, normally plant shifts are uneventful. I recall I was on watch as RO and the EO Under Instruction, (UI) was doing a plant shift for qualification. The shift qualified Electric Operator, UI, and the Engineer Officer of the Watch (EOOW) talked through the plant shift prior to operating the plant. Finally, the EOOW gave the order to perform the shift. 

In retrospect, I am not sure of the synchroscope’s position when the UI attempted to shut the breaker. Let’s say the position was nowhere close from the loud boom everyone heard.  After I looked at my panel my pump configuration I lost a pump on each side i.e.1 Slow- 1 Slow. I had two pumps running on each side before the shift.

After the restoring the plant E Div ensured no damage had occurred to the breaker.  On this day we were lucky, for those of you who might not have been so fortunate what was the craziest thing you have seen during a messed up plant shift and what happened afterwards?
