Subject:

50.55a Rulemaking After some fits and starts, we are trying to settle on the approach to be taken for the famous 50.55a ru3emaking.

We are proceeding _ based on Brian Sheron's memo to you, and your agreement with-it (I believe),-

We will retain words that say " 120-month update requirement."

However, all future code changes, except for safety significant, will be voluntary. Thus, upon a licensee's arrival at his 120-month update anniversary, THERE WILL NOTHING TO UPDATE!. So, while_we still say we have a 120-month update requirement, it will indeed be toothless. Any code change we feel to be safety significant will have to be backfitted per your agreement..( I don't know how to cut the cheese between 4 safety-significant change;to be imposed immediately and one to be imposed at the 120-month updata. Thus, I'm saying that any such ss change will be done NOW, and there will be nothing left to uipdate at 120 months.)-

Interestingly, this brings us to a de facto baseline at the ASME-XI 1989-and O&M 1990 level - very nearly what Entergy

. _w anted, except that we will expect the industry to update that L one last time to the 89/90 code, t

Is this really what you wanted, or did you believe that you-wished for/ agreed to the regular old 120-month update wherein lictnsees HUST pick up all code changes once in 120 months, whether administrative or safet3 significant?

Thanks for your consideration, and I await your answer with interest.
