The steam dump opened causing a high steamline flow, coincident with a low Tavg.

This initiated a safety injection, which caused the Boron Injection Tank concentration to decrease to less than 20,000 ppm of boron.

Action Statement 3.5.4.1 was entered.

This constituted operation in a degraded mode IAW Technical Specifi-cation 6.9.1.9.b.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The safety injection diluted the Boron Injection Tank to less than 20,000 ppm of boron.

ANALYSIS OF OCCURRENCE:

Technical Specification 3.5.4.1 requires that with the Boron Injection Tank inoperable, restore the tank to operable status within one hour or be in hot standby and borated to shutdown margin equivalent to 1% Ak/k at 200 t within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />; restore the tank to operable status within the next 7 days or be in hot shutdown within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
