Abnormal Occurr2nce No. A0 75-37

Dear Mr. O'Reilly:

[

This telegram is to confirm the conversation between Mr. Lee Spessa'rd I

(Region I-URC) and Mr. J. J. Colitz (TMI-Unit 1 Superintendent) at 4915 hours0.0569 days <br />1.365 hours <br />0.00813 weeks <br />0.00187 months <br /> on October 21. 1975.

The following report is submitted in accordance with paragraph 6.7.2a.1 (page 6-11) of the Technical Specifications.

[

On October 21, 1975, tne Boric Acid Mix Tank was <fesignated as the tank to meet Tech. Spec. 3.2.2 requirements.

While boric acid was being transferred from the Boric Acid Mix Tank to a i

Reclaimed Boric Acid Storage Tank, the cocinon suction strainer for the I

Boric Acid Pumps collected sufficient fines to partially obstruct the flow

)

of beric acid.

1 Since the Boric Acid Mix Tank was the Tech. Spec. Tank, the strainer change-cut necessitated removing the tank from operable status for approximately 15 minutes. During this time period, a reduction in plant power was conanenced.

a The strainer was replaced within approximately 15 minutes and the Boric Acid l

Mix Tank and addition system was declared operable per Tech. Spec. 3.2.2.

l The power reduction was then tennicated and the plant restored to the previous power level.

s l

Very truly yours.
