SUBJECT:

THREE MILE ISLAND NUCLEAR GENERATING STATION UNIT 1 -

RESPONSE TO GENERIC LETTER 98-01, " YEAR 2000 READINESS OF l

COMPUTER SYSTEMS AT NUCLEAR POWER PLANTS" l

(TAC NO. MA1899)

Dear Mr. Langenbach:

In Generic Letter 98-01," Year 2000 Readiness of Computer Systems at Nuc! ear Power Plants" and its Supplement 1, we requested utilities to submit plans and schedules for resolving Y2K-related issues. We have received and reviewed alllicensees' corrective plans and schedules. Based on our review of licensee responses and our onsite assessment of licensee Y2K activities as described in NUREG-1706, " Year 2000 Readiness in U.S. Nuclear Power Plants," we have concluded that there are no nuclear plants with Y2K issues involving safety

systems, increased public awareness and attention to the Y2K issue have resulted in concern over the ability of nuclear power plants to provide uninterrupted power to the national electric power grid during the Y2K transition. In this regard, we are focusing attention beyond those systems necessary to maintain safety. Consequently, we are closely monitoring those plants having Y2K deficiencies in systems that could impact plant operation that are not scheduled for l

remediation prior to September 30,1999. As you are aware, a Y2K deficiency in certain systems or components might cause a transient during the Y2K transition that could affect the national electric power grid.

In your letter of July 1,1999, for the Three Mile Island Nuclear Generating Station, Unit 1 (TMI-1), you stated the following:

i TMI-1 will not be Y2K ready until you make changes to the following systems:

l

a. Digital Turbine Control System l

b. ETUDE (Software system for controlling personnel qualifications)

)

l

c. REM /AACS/CICO (Integrated software system for managing personnel radiation i

j exposure and controlling access to radiologically controlled

(/

areas) c[ Offi You intend to complete these systen changes by the end of the thirteenth refueling outage which began on September 10,1999.

9 J.Langenbach September 23, 1999 it is our understanding that the Digital Turbine Control System, which is currently not Y2K ready, may have the potential to cause a transient during the Y2K transition or be important to continued power operation at your facility. The NRC considers it important to complete these Y2K remediation efforts in advance of the Y2K transition date. To efficiently schedule regional inspecuons to verify completion of the Y2K work, you are requested to inform the staff of any changes in (1) the scope of the Y2K system deficiencies listed above, or (2) your projected completion schedule. Please submit a letter documenting when work is complete.

We would like to acknowledge the efforts you have completed to date in preparing your plant for the Y2K transition and appreciate your continued cooperation on this important issue.

The collection of this information is covered by OMB Clearance 3150-0012 which expires on June 30,2000.
