SCRAM: (aka SCRAMjet) Supersonic Combustion Ramjet
CRUD: no entry. Under CRU we have Control Radio Unit, under CRD there is
Control Radio Dialer.
Note: the military or technical usages of these words are NOT the origin of
the words as they are commonly used (this is in distinction to words like
SNAFU).

From the online OED entry for "crud":
1959 New Scientist 26 Mar. 696/1 `Crud' (Chalk River Unidentified
Deposit), an impolite word applied to rust deposited on the fuel
elements in the high radiation zones which exist in the heart of a
reactor.
Now "Scram" has a meaning related to nuclear reactors, too:
scram (skraem), v.[3] Nucl. Physics. [Etym. unkn., but see note s.v.
SCRAM sb.[2]] a trans. To shut down (a nuclear reactor), usu. in an
emergency.
scram (skraem), sb.[2] Nucl. Physics. [f. SCRAM v.[3]] The rapid
shutting down of a nuclear reactor, usu. in an emergency. Freq.
attrib. Both this word and SCRAM v.[3] are possibly derived from SCRAM
v.[2]

Programmers and System designers use CRUD to mean Create, Read, Update, Delete.
These are things that need to be specified at design time in terms of who has
permission to do which. One talks about the CRUD specifications for a
database.
Of course "crud" as a noun has been around for a long time as has "scram"
as a verb.

If you insist that they're acronyms, I can't help you. But, both terms
are used in nuclear engineering.
Scram is a term used for an emergency shutdown of a nuclear reactor.
Crud is dirt and debris that fouls the piping of a reactor.
You might be interested in looking up the earliest meaning of "crud" in
Flexner and Wentworth's "Dictionary of American Slang." It's listed as
"taboo" and is too indelicate to quote here.

There is a web site for this:
http://www.ucc.ie/info/net/acronyms/acro.html
In this case, the answers are
SCRAM
Safety Crew Reactor Axe Man [term used to indicate emergency
reactor shutdown]
Secondary Control Rod Axe Man [emergency shutdown procedure
for early fission experiments]
Static Column RAM (h/w)
CRUD
Chalk River Unidentified Deposits

The "M" is SCRAM stands for "missile," but I'm not sure of the rest. It
was a solid-fuel anti-missile missle, as I recall.

Both SCRAM and CRUD are used in the U.S. Navy's Nuclear Propulsion
Program.
A SCRAM is an emergency shutdown of a nuclear reactor accomplished by
the rapidl insertion of control rods under gravity, with a spring
assist. BTW, it is a very big spring doing the assisting. A full SCRAM
shuts the reactor down right now and no excuses!
The term is said to have originated with the Manhattan Project.
According to the story I heard, the control rods were secured with
ropes and a man was stationed to cut the ropes with an axe in the
event of an emergency. This was the Safty Control Rod Axe Man.
I have my doubts about the story; but, it is colorful.
CRUD is nasty stuff found inside the reactor made up of corrosion
productions which have been made radioactive by exposure to the
reactor.
Supposedly, the stuff was first found in the Chalk River Reactor and
is an acronym for Chalk River Undetermined Deposits. This may be folk
lore.

I served in a nuclear submarine in a non-nuclear billet. I was told
the following by the nuclear-trained officers, but I take it with a
grain.
SCRAM, used both as a noun and verb, means to, either manually or by
automatic action of the control circuits, take a reactor non-critical
by swiftly inserting the control rods. This is commonly done in the
Navy for training, but also happens very occasionally by accident. In
the second case it results in frantic action by the engineers to
restore the reactor to normal operation (sitting submerged in
mid-ocean without propulsion or any but a battery-supplied electric
supply is not fun.)
I was told the origin of the term goes back to the pre-Manhattan
Project pile constructed by Dr. Fermi in a squash court inder the
University of Chicago. (1940?) This first reactor really was a 'pile',
a mass of graphite bricks, open at the top, containing the fuel
elements. Control rods were raised and lowered by a winch.
As a secondary saftey device in case of a runaway reaction, a large
bucket of boron (a neutron 'poison') was hung over the open pile by a
rope. The rope ran through a pulley and down to a wall bracket.
Mounted next to the bracket was a hatchet, and a sign hung over the
hatchet. It read: Swiftly Cut Rope And Move.
Believe it, or not . . .

Years ago my brother told me
that CRUD stands for Chalk River [or chalk river] unidentified deposit.
Brother was never known to be wrong except when he told
me that if you squeeze an egg along its long axis it won't break.

The term Scram was in use when I was at school, and that was a
long time ago. When I was a lad, scram meant, ``let's get
out of here fast''. My buest guess is that scram is a
contraction of ``scramble'', meaning, let's get the squadron
of airplanes off the ground and into the air as fast as possible.
And that usage dates back to between the two world wars.
Scram is also used these days in the term Scramjet, meaning a
Supersonic Combustion Ramjet.

My understanding is that SCRAM comes from early nuclear reactor
research. The control rods were suspended in a frame held up by a
rope. The safety mechanism was a guy with an axe ready to cut the
rope.
SCRAM allegedly was "Start Chopping Right Away Man!". :-)
Then again that could be an urban myth...

and Delete. These are the four functions that an application needs to
support in order to maintain an individual data item. So you could say that
"This form has full CRUD capability."
SCRAM? No, idea.
