Inoperable Boron Injection Tank CONDITIONS PRIOR TO OCCURRENCE:

Unit in Mode 3, recovering from Reactor Trip/Safety Injection.

DESCRIPTION OF OCCORRENCE:

Following a Reactor Trip/Safety Injection, the Boron Injection Tank was declared inoperable due to the Boron concentration being below the minimum concentration allowed by the Technical Specifications, LCO 3

• 5

• 4

• 1.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

Loss of Boron Concentration was caused by a High Steam line flow coincident with low Tave Safety Injection.

ANALYSIS OF OCCURRENCE:

The Boron Injection Tank was returned to an operable status within the time allowed by Technical Specifications. At no time was there any danger to the general public or site personnel.

CORRECTIVE ACTION:

Emergency Instruction I-4.2 was implemented and the boron concentration in the Boron Injection Tank was returned to within the Technical Speci-fication values. Boron samples confirmed operability.

FAILURE DATA:

Not applicable.
