DESCRIPTION OF OCCURRENCE:

On May 1, 1982, during routine startup operation, the Control Room Operator discovered that No. 13 Steam Generator Wide Range Level indication had failed low.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

A piece of solid wire was found shorting the instrument signal-lead to-the conductor shield.

ANALYSIS OF OCCURRENCE:

Technical Specification 3.3.3.7.a Action 1 requires-With the number of operable accident monitoring channels less than the required number of channels, restore the inoperable channel (s) to an operable status within 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 />.
