NORTH CAROLINA AGREEMENT STATE REPORT - DAMAGED TROXLER

The following information was reported by facsimile.

The North Carolina Department of Environment and Natural Resources reported a damaged Troxler moisture density gage during construction activities in Reidsville, NC. The NC Radiation Protection Section dispatched a health physicist to the site, the health physicist secured the damaged gage on site and conducted radiation exposure surveys to access the status of the radioactive sources. All indications and surveys support that no radiological damage occurred to those workers involved and no damage was incurred to the environment.

Damage to the gage resulted in a potential loss of shielding. If the gage is mishandled the source rod will pull out. The gage was secured and the sliding block was closed.

Stakeholders and responsible parties were contacted and are arranging to have the gage appropriately transferred to the manufacturer for further evaluation.

Troxler Model # 3430, S/N 34504

Radiological Information:
Cs-137 10 milliCi S/N 77-1449
Am/Be 40 milliCi S/N 47-29961

Survey Results:
Background: 20 microR/hr
three inches from gage: 8 milliR/hr
After gage removed: 20 microR/hr (no indication of contamination)

HIGH PRESSURE COOLANT INJECTION (HPCI) DECLARED INOPERABLE BASED ON INABILITY TO VERIFY HPCI KEEP FILL FUNCTION REQUIRED BY TECHNICAL SPECIFICATIONS

"At 23:53 CST Unit 2 HPCI pump suction automatically transferred from the Condensate Storage Tank to the Suppression Pool. This caused HPCI to be declared inoperable due to not meeting Technical Specification Surveillance Requirement 3.5.1.1. HPCI keep fill could not be verified so HPCI was declared inoperable.

"This event is being reported pursuant to 10CFR 50.72(b)(3)(v) as 'Any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to: (D) Mitigate the consequences of an accident.'"

HPCI remains inoperable pending venting of the system. The licensee is conducting an investigation to determine the root cause for the automatic transfer.

The licensee informed the NRC Resident Inspector.
