Attachment Page 1 Serial No. 041 RESPONSE TO NOTICE OF VIOLATION INSPECTION REPORT NOS. 50-280/82-34 AND 50-281/82-34 NRC COMMENT:
10 -CFR 50.59 requires that the licensee shall maintain records of changes to the facility as described in the final safety analysis report (FSAR).
These records shall include a written safety evaluation which provides the bases for the determination that. the change does not involve an unreviewed safety question.
Contrary to the -above, records, including a written safety evaluation, were neither generated nor maintained when a change to the facility, as described in the FSAR,' was made. Two inch diameter clear tygon tubing was installed on the component cooling water (CCW) system surge tank in parallel with the level indicators. On November 9, 1982, the tygon tubing blew off the surge tank and released radioactive gases into the auxiliary building. The gas flowed to the ventilation vent effluent stack,.where the activity was measured as being some 30% of the Technical Specification 3.11.B.1 limit.
This is a Severity Level IV Violation (Supplement I.)
RESPONSE
(1) ADMISSION OR DENIAL OF THE ALLEGED VIOLATION:
The violation is correct as stated.
(2) REASONS FOR VIOLATION:
This event was discovered and notification made to the NRC by the Licensee.
The release did not violate Technical Specification.
The temporary level column was installed by Operations Department at an unknown time.
The time was most probably many years ago in order to provide an independent. indication of level for a specific evolution. At that time no Jumper Log entry was made.
As the improved procedural controls were developed and because of the physical location of the temporary tubing we failed to register the jumper.
(3) CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED:
The hose blew off as the tank was being refilled with its vent closed.
This was necessary due to the higher than normal activity in the component cooling water system. The potential overpressure stress on the tank has been evaluated and shows its design pressure was not exceeded.
The hose
. as permanently removed.
The Operations Department was w
instructed on the potential of tank filling overpressurization and filling methods to protect against overpressurization. The proper use of the Jumper Log was reemphasized. Subsequent tank filling evolutions have been successful.
(4) CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS:
No additional steps are necessary.
(5) THE DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED:
'iance has been achieved.
