SUBJECT:
COMPLETION OF LICENSING ACTIVITYFOR GENERIC LETTER 98-01 AND SUPPLEMENT 1
- DIABLOCANYON POWER PLANT, UNIT NOS.
1 AND 2 (TAC NOS. MA1830 AND MA1831)
Dear Mr. Rueger:
On May 11, 1998, the U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter 98-01, 'Year 2000 Readiness of Computer Systems at Nuclear Power Plants," to all holders of operating licenses for nuclear power plants, except those who have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel.
The NRC issued GL 98-01 to ensure that licensees were adequately addressing potential date-related errors with computer systems, embedded software devices, and software applications sufficiently in advance of the Year 2000 (Y2K) rollover date to ensure that nuclear power plants willbe in a stable, safe condition during the Y2Ktransition.
Subsequent to the issuance of GL 98-01, increased public awareness and government attention to the Y2K issue resulted in concern over not only public health and safety of nuclear power plants, but also concern over the ability of nuclear power plants to continue to provide power to the national electric power grid. Therefore, on January 14, 1999, the staff issued Supplement 1 to GL-98-01 to provide addressees with a voluntary, alternative response to that required in item (2) of GL 98-01.
In responding to Supplement 1, addressees were asked to confirm Y2K readiness of the facilitywith regard to those systems within the scope of the license and NRC regulations, as well as those systems required for continued operation of the facilityafter January 1, 2000. Addressees were permitted to voluntarily respond to Supplement 1 to GL 98-01 on or before July 1, 1999, in lieu of item (2) of GL 98-01.
/o In response to GL 98-01, you provided letters dated August 7, 1998, July 1 and September 23, 1999 for Diablo Canyon Power Plant, Unit Nos.
1 and 2. These submittals provided the information requested by GL 98-01. The staff has reviewed your response and has concluded that all requested information has been provided. Therefore, we consider GL 98-01 to be closed for the Diablo Canyon Power Plant, Unit Nos.
1 and 2.
NUREG-1706, "Year 2000 Readiness in U.S. Nuclear Power Plants," provides a status of nuclear power plant Year 2000 readiness as of September 1, 1999, and a description of NRC actions to determine Y2K readiness in operating U.S. reactors.

Mr. Gregory M. Rueger September 29, 1999 readiness consisted of independently evaluating nuclear power plant licensee Y2K readiness program processes, reviewing licensee responses to NRC requests for reporting Y2K readiness (i.e., GL 98-01 and Supplement 1), and combining the results on these assessments to achieve a high level of assuran'ce that each facilitywill operate safely during the transition from 1999 to 2000 and on other Y2K sensitive dates.
NUREG-1706 is linked to the NRC home page (http:/www.nrc.gov/NRC/NEWS/year2000.html).
We would like to acknowledge the efforts you have completed to date in preparing your plant for the Y2Ktransition and appreciate your continued cooperation on this important issue.
Ifyou have any questions regarding this matter, please contact me at (301) 415-1313.
