Y5u req' vested an explanatica as to why the safety concern dealing with the CT5G water level operating procedures, which was dis-covered on the TECO plant, was not passed on to *NI-I more promp tly. It should have been, and t.Yire is not a good reason why it was not.

It had not died at any point, but it did move more slowly than it should have. We are taking steps to assure quicker action in the fu:ure on safety, concerns affecting operating plants.

D For your information, a brief chronology of events en this con.

cern is presented below.

" 6/3/77 Preliminary Safety Concern flied -

Preliminary revised operating procedures L

had already been sent to TECO .

6/8/77 Evaluation of c6ncern initiated 6/15/77 ect Managenent Engineering recommending letter customer to Projfication not. of need to change procedures **

• 1/:7/78 evaluations performed to finali:e required

. tech spec and pr:cedure changes 2/1/73 blI-1 was advised that their cperating procedures mus: e changed N

.. In retrospect. I believe ene of the reascas 7MI was .ot notified earlier was due to the appicpriate Nuclear Service =anager not being involved in the early nee:ings en this subfect sr.:1 not
