l o 121 l During the recovery from an inadvertant Safety Injection, the Boron Injection Tank l

o,3, l was isolated, drained and recirculation flow was re-established to the Boric Acid l

go;,;l Storage Tanks.

After the refill was completed, sample analysis indicated the Boric 1 10 l s i i Acid Storage Tank boron concentration was less than 20,000 ppm.

At 1120 hours0.013 days <br />0.311 hours <br />0.00185 weeks <br />4.2616e-4 months <br />, on l
