ALARP?

I think it's a Limey thing.
"38.3.3 The ALARP Principle
The ALARP (“as low as reasonably practicable”; see Figure 38.5) principle is sometimes used in the oil and gas industry (UK HSE, 1992). The use of the ALARP principle may be interpreted as, satisfying a requirement to keep the risk level “as low as possible” provided that the ALARP evaluations are extensively documented. In the ALARP region (between “lower tolerable limit” and “upper tolerable limit”), the risk is tolerable, only if risk reduction is impracticable or if its cost is grossly disproportionate to the improvement gained. The common way to determine what is practicable is to use cost–benefit evaluations as a basis for the decision on whether certain risk reducing measures should be implemented..."

ALARA was originally (and briefly) ALAP -- As Low As Practicable, but that word is not well recognized (or pronounced) in the US so they changed it to ALARA hoping that people would understand its meaning when deciphered.
I had not seen ALARP before. Just struck me funny for some reason.

It is an acronym which will put on the brakes of an domestic nuke skimming the article. Got me a bit google eyed.

may as well have stated "reasonably reasonable",...

That would be true if the word was practical and not practicable. Reasonably practical is somewhat redundant, but reasonably practicable is not.
