CW0557/59 Vacuum Breaker Vault Leaak On 11-20-00 water was observed leaking from the CW057/58 Vacuum Breaker Vault. It was estimated the leak had been occurring for approximately 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. Tritium samples were taken from three locations: the vault, center of the south end of the 345' switchyard fence, and from the southwest end of the 345' switchyard fence. A gamma isotopic was

• pVriomned on the water from the vault.

No radioactive releases were performed during the period of the lealing vacuum breaker.

Gamma istopotic analysis indicated no quantifiable peaks. All tritium analyses were below the lower limit of detection (1.87E-06 uCi/mil).

No further sampling warranted.
