Dear Sirs:
The purpose of this letter is to provide the NRC a summary of the activities at TMI-2 during the 1" quarter of 1998.
There was no inspection of the TM1-2 Reactor Building during the 1" quarter of 1998. The next inspection of the TMI-2 Reactor Building is scheduled for June 1998.
i Routine radiological surveys of the suxiliary and Fuel Handling Buildings during the 1" quarter of 1998 did not identify any significant adverse radiological trends.
The Reactor Vessel temperature monitoring system reported the Reactor Vessel temperatures ranged from 51.1 F on January 1,1998 to 46.8 F on March 25 and 26,1998. The Reactor Building temperature ranged from 49.3 F on March 31,1998 to 45.3 F on January 31,1998.
The largest temperature difference between the Reactor Building and the Reactor Vessel occurred on January 2 and 3,1998, when the Reactor Building temperature was 4.3 F less than the Reactor Vessel temperature.

Significant work activities during the 1" quarter of 1998 included correction of improperly positioned Reactor Brilding containment isolation valves, discovered during performance of a surveillance in Februaiy 1998. The associated upstream isolation valves were verified to have j
been in the closed position, thus providing containment isolation. In addition, various repairs
{
were performed on poitions of the electrical system, service air system, and ventilation systems.
Dismantlemen* p" non-radiological equipment continued with the removal of piping, inactive
{
electrical circuits, and othei miscellaneous material located in the Service Building, Control i
Building, and the Turbine Building.
Please contact Adam Miller of the TMI Nuclear Safety and Licensing Department at (717) 948-8128 if you have any questions regarding this report.
