SUBJECT:
NRC INTEGRATED INSPECTION REPORT NO. 50-289/99-04 AND EXERCISE
Dear Mr. Langenbach:
On July 17,1999, the NRC completed an integrated inspection at your Three Mile Island Unit 1 -
reactor facility. The enclosed report presents the results of that inspection which the resident
inspectors discussed with you and your staff during the July 21,1999, exit meeting.
Your staff operated the unit safely throughout the inspection period. Conduct of routine control .
room operations continued to be a strength. Operators reacted appropriately, and plant
equipment responded, as designed, to the loss of the B auxiliary transformer. The quality of
your fire protection program was found to be good
We have completed our review of the 28 emergency feedwater (EFW) pump bearing failure
identified by your staff in May 1999. The bearing failure was documented in NRC inspection
report 50-289/99-03, dated June 29,1999. GPUN and the NRC determined that the 2B EFW
pump was unavailable to perform its safety function, due to the failed bearing, for longer than the
TS allowed out of service time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The 2B EFW pump was inoperable from the time of
the last automatic actuation start test on March 27,1999, or earlier, until the time of discovery of
the failed bearing on May 10,1999. The NRC staff found that you could not have reasonably
predicted the failure of the pump bearing based on the results of past surveillance testing and
)
that the cause of the failure was not indicative of your current performance in the conduct of
maintenance activities.' Further, your corrective actions for this event were commensurate with
i
the safety significance of the emergency feedwater system. - Accordingly, in consultation with
the Regional Administrator, NRC Region 1, and the Director, NRC Office of Enforcement, I have
-
- been authorized to not issue a Notice of Violation and not propose a civil penalty for this Severity
'
Level ill violation in accordance with the provisions provided in Section Vll.B.6 of the
'
i
i
' Based on the results of this inspection, the NRC has determined that two Severity Level IV
violations of NRC requirements occurred which you identified. These violations are being
,
- treated as Non-Cited Violations (NCVs), consistent with Appendix C of the Enforcement Policy.
The NCV's involved: 1) inability of the control building emergency ventilation system to maintain

the control room at a positive pressure in the event of a damper failure, and 2) the existence of
an open flood path between the turbine building and the control building. These NCVs are
described further in the subject inspection report. If you contest the violations or severity level of
these NCVs , you should provide a response within 30 days of the date of this inspection report,
with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control
Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region 1; the
Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington,
DC 20555-0001; and the NRC Resident inspector at the Three Mile Island Unit i reactor facility.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its
enclosures will be placed in the NRC Public Document Room (PDR).
No reply to this letter is necessary. We appreciate your cooperation.
