September 10, 1999 l
The Honorable Paul D. Coverdell United States Senator 100 Colony Square, Suite 300 1175 Peachtree Street N. E.
Atlanta, Georgia 30361 I
Dear Senator Coverdell:
I am responding to your letter to Mr. Dennis Rathbun of August 9,1999. You asked us to reviewJohn Sherman's letter of August 2,1999, and reply to you at your Georgia office.
i Mr. Sherman is concemed that the Farley Nuclear Plant and other nuclear plants are not yet Year 2000 (Y2K) compliant. He mentioned the following issues associated with nuclear plant j
Y2K compliance:
j (1) Farley's Y2K ready date (not compliant date) is December 16,1999.
(2) It takes 4 to 6 months to shut down a reactor, and the reactor must be cooled the entire time.
(3) The Farley plant and other Y2K non-compliant plants should be shut down right now if items (1) and (2) are correct.
Before I address the Farley Nuclear Plant, I want to explain the difference between the terms "Y2K ready and "Y2K compliant." "Y2K compliant" generally means that computer systems or applications will accurately process date/ time data from, into, and between the twentieth and twenty-first century (the years 1999 and 2000), and leap-year calculations. "Y2K ready" generally means that a computer system or application is suitable for continued use into the year 2000 even though the computer system, application, or device is not fully Y2K compliant.
j in other words, being Y2K ready means Farley Nuclear Plant components would function properly through rollover to the new millennium even though they might not display the correct date on a readout device, chart or recorder. For v2K ready systems, utilities may have to take j
additional measures to ensure that the systems, components, and equipment function as
{
intended. For example, plant operators could set a computer clock back to another year to make a system Y2K ready. The system would still function properly through rollover to the new
/
millennium. They would then make the system Y2K compliant at a later date. Most nuclear
[
plant items are now Y2K compliant.
1 In response to item (1), the Farley Nuclear Plant, Unit 1, is Y2K ready. However, to make the g
second Farley plant (Unit 2) Y2K ready, Southern Nuclear Operating Company (SNC) needs to
/01 I
fix one more item. SNC needs to modify and test computer software on its system that controls h the Unit 2 steam turbine. The system that controls the steam turbine does not affect plant y
)
safety. The steam turbine tums an attached electrical generator to produce electricity. SNC has successfully modified and tested the turbine control computer software on Unit 1, but it 4
needs to wait until the next Unit 2 refueling shutdown later this Fall to modify and test the Unit 2 j
steam turbine computer software.

Honorable Paul D. Coverdell
- Regarding items (2) and (3), SNC completes a routine Farley plant shutdown from full operating power in about 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />, it takes only a few seconds to manually or automatically shut down a nuclear plant in an emergency. These routine and emergency shutdown times are reasonable averages for all nuclear power plants. SNC plans to shut down Unit 2 for refueling and other maintenance, modify and test the software, and begin producing power again by about l
December 16,1999. We do not expect the Y2K issue to affect the safety of the Farley Nuclear Plant, Units 1 and 2, or their ability to supply electrical power to the national electric power grid.
Thus, wa see no reason to shut down Farley Nuclear Plant, Units 1 and 2. Furthermore, we have undertaken an exhaustive effort to ensure that all nuclear power plants that are not fully ready for Y2K are on track to be Y2K ready before the end of the year.
Enclosed is the latest NRC status report on Y2K activities. We recently completed our onsite Y2K reviews at all 103 U.S. nuclear power plants and have confirmed that there are no Y2K-related problems which affect the performance of safety systems needed to safely shut down the plants. More Y2K Information is available on our Web site at http://www.nrc.aov/NRC/Y2K/Y2KReadv.html.
1 hope that this information is responsive to Mr. Sherman's concerns. I am happy to give you any more details that you might need.

- Nuclear Regulatory Cominission Status Report on Year 2000 Activities for August 1999
~
INTRODUCTION This report is the.elghth periodic report on the status of agency Y2K activities. The report covers the period from July 1 through July 31,1999. More detailed Y2K-related information and the previous periodic reports to the Commission can be found on NRC's Y2K website at htto://www.nrc.oov/NRC/ NEWS /vear2000.html.
POWER REACTORS By July 1,1999, all 103 operating nuclear power plants reported status of Y2K readiness to the NRC. Regarding NRC's highest priority-the uninterrupted performance of plant safety t
systems-all nuclear power plants report that their efforts are complete, and that no remaining Y2K-related problems exist that could directly affect the performance of safety systems or the capability for safe shutdown. Sixty-eight'of these plants had also completed the next order of priority as of July 1, stating that all of their computer systems that support plant operation are "Y2K ready." The remaining 35 plants reported that, to be fully Y2K ready, they still have additional work to complete on a few non-safety computer systems or devices. For about one half of those 35 plants, some work remains on systems needed for power generation. Other plants must perform remediation on plant monitoring and administrative systems. Typically, the remaining Y2K work is waiting on a scheduled plant outage in the fall, or delayed while awaitin the delivery of a replacement component. In each case, the licensees with work remaining have provided satisfactory schedules for completing that work.
By July 30, five more plants reported Y2K ready, raising the total to 73. Table 1 (attached) lis those plants for which the licensee has provided written confirmation that the facility is Y2K ready. Table 2 (attached) provides a summary of remaining Y2K work items for those facilities that were not Y2K ready as of July 30,1999. The information in Table 2 has been extracted from the recent licensee response to Generic Letter 98-01, Supplement 1 and, in sonie cases contains an initial staff assessment of the significance of the remaining work. Seventeen plants have work remaining on systems impacting power generation and 13 plants have work remaining on monitoring or administrative systems. Additional staff assessment and updated information and will be provided in a NUREG document scheduled to be issued by August 31, 1999.
The NRC issued a preliminary report on Nuclear Power Plant Y2K Readiness on July 19,1999.
This report integrated the results of the regional on-site reviews with the results of the initial staff review of licensee responses to GL 98-01, Supplement 1. This report has been placed on the NRC Web site. Audit reports for all six Headquarters audits of licensees Y2K contingency plans have been made publicly available and have also been posted on the NRC Y2K Web site.

' During ourintegrated review of the responses to the GL 98 01 responses and the results of o
- independent inspection activities, we did not identify any significant inconsistencies or issues that required additional regulatory action. However, because we were not able to complete our
. assessment ' checklist at 14 plants, in large part due to the stage of readiness and program implementation of some of our licensees at the time of the inspection, we planned to conduct follow-up reviews at those 14 plants to provide additional confidence that implementation of their raarfiness activities is consistent with NRC-endorsed industry guidance. Follow-up reviews for alght of those plants have since been completed. Review activities are scheduled for the remaining six plants: Beaver Valley Units 1 and 2, Indian Point 2, Three Mile Island 1, Vermont Yankee, and Cooper.'
The few plants that have V2K work remaining are continuing to progress toward Y2K readiness.
As of August 1,1999, 5 more plants have reported that they are Y2K ready. These plants are Saint Lucie Units 1 and 2, Turkey Point' Units 3 and 4, and Monticello.

7/1/99 8/1/99 B/1/99 10/1/99 11/1/99 12/1/99 1/1/00 Date (Month) plants still have Y2K work remaining and 73 plants are reporting Y2K readiness. As depicted in the above chart, we expect.this trend to continue. Based on the information available, by November 1,1999, only six plants will have Y2K work remaining.
Of the 6 plants with remaining Y2K work after November 1,1999, two (the DC Cook units) are in an extended plant shutdown (issues not related to Y2K) and have only minor Y2K work-remaining on non-safety plant support systems, which the licensee plans to complete by

December 15,1999. These two units will remain shutdown during the Y2'K transition. The four
- other plants (Brunswick Unit 1, Comanche Peak Unit 1, Salem Unit 1, and Farley Unit 2 an outage to complete their Y2K.actMtles. These outages have been scheduled and each of these licensees has successfully completed the most significant Y2K remediation activities on sister units.
nWom.a.i!! continue to monitor progress at those plants that have ' remaining work to be performed and wlHndependently verify completion of these items, including Y2K conting plans. By September 30,1999, we will make a final determination whether additional re action is' warranted to address Y2K readiness issues. At this time, we believe that all licensees will be able to operate their plants safely during the transition from 1999 to 2000, and we do not anticipate the need for the NRC to direct any plant-specific action.
The staffis revising Temporary Instruction (TI) 2515t141 to include the necessary guidance to conduct followup reviews of the remaining non-safety items associated with 35 plants whose licensees reported they we're not fully Y2K ready on July 1,1999. The schedule for this effort is determined by the licensee's projected completion schedule.
. The staff will attend a workshop sponsored by the North American Electric Reliability Council on August 5-6,1999. The purpose of this workshop is to share information concerr'ing Y2K issues. Co-sponsors of the workshop are.EPRI, NEl, and others., At this workshop, tne staff will give a presentation on the status of NRC Y2K actMties.
FUEL CYCLE FACILITIES ANI MATERIALS LICENSEES The Office of Nuclear Material Safety and Safeguards (NMSS) and DOE are working together to provide a single Federal govemment response to an IAEA Y2K Safeguards Questionnaire.
NMSS p siously responded to an IAEA Y2K Safety Questionnaire for Fuel Cycle Facilities.
HMSS representatives are scheduled to visit Portsmouth gaseous diffusion plant (GDP) the week of August 16,1999, and Paducah GDP the week of September 20,1999 to discuss Y2K readiness activities.
NMSS reviewed the third set of responses to Generic Letter 98-03. A summary of the responses is attached. The licensee for Allied Signal indicated, in a follow-up discussion, that their facility was Y2K ready by July 1,1999.
A summary of the Y2K readiness status of major fuel cycle facilities follows. This information is based, in large, part on information contained in licensee / certificate holder response to Generic Letter 98-03 and is current as of July 28,1999.

' CONTINGENCY PLANNING On July 14th NRC conducted a Y2K Talbletop exercise with Baltimore Gas and Electric, the State of Maryland and the counties sunounding the Calvert Cliffs nuclear power plant. %e exercise tested Y2K contingency plan procedures against a number of scenarios, inclu
. of power and loss of telecommunicaeons. The exercise confirmed that each participant ha put c car.:,Liarable amount of Rioupthto preparing for potential problems during the Y2K transition. Although no major Y2Kisselingency plan inconsistencies were identified, there we a number of valuable observations and lessons from this tabletop. A synopsis of this exercise is on the Y2K web' site (under Contingency Planning).
The staffis preparing for the full scale Y2K exercise. The exercise is scheduled for October -
th and will test all aspects of the Y2K contingency plan, including the use of back 15 communication systems and the sharing ofinformation using the Y2K early waming s (YEWS). During this exercise the NRC Operations Centerand the Regionalincident Response Centers will be staffed in accordance with the Y2K contingency plan. Approx 10 licensees will simulate requests forenforcement discretion. In addition, at least two licensees (including one fuel cycle fadllity) will simulate an emergency because of a Y2K problem. The exercise will also involve a simulated Headquarters communication failure and transfer to the Region IV back-up Operations Center. Back-up communication systems between NRC headquartem, the regional incident Response Centers and the' resident inspectors will also be tested. The NRC auditorium will be established as a mock Joint information center (JIC) for the White House Information Coordination Center. J students from local universities'have been invited to play the role of the press., The NRC Information Coordination Center representative will provide briefings in the auditorium (simulated JIC) on the status of Y2K problems in the nuclear industry.
The staff placed the order for Iridium satellite phones and the phones were shipped to the Regions and Headquarters for inventory control tagging before beln'g distributed. NRC's dedicated link from the National Telecommunication Coordinating Network to the Headquarte Operations Center was installed. FEMA recently announced plans to install NAWAS (Nationa l
Waming System) circuits in all Federal Response Plan signatory Agencies (including NRC) part of its Y2K preparedness effoit Details of this plan will be discussed at a meeting on Au 17 at FEMA Headquarters.
1
. The staff issued an l'nformation natiop, IN 99-25, " Year 2000 Contingency Planning Activities" to nuclear power plant licensees and fuel cycle facilities providing information conoeming the NRC's Y2K contingency plan.
i INTERNATIONAL PROGRAMS The staff has assisted the Nuclear Energy Agency in developing a prototype of an intemational Y2K early waming system (YEWS)ihat would be used by the NRC and other regulators to share information concoming Y2K problems that affect plant operation, telecommunications, or grid reliability. YEWS is a global intemet-based communications system allowing the rapid transmission of information on Y2K related occurrences affecting nuclear facility operations, loca! gdd etability and telecommunications during the Y2K transition period.
Page 5 of 7
The staf!' plans to place this system on a secure web server at a National Latw.Ly. A number of countries (most notably Japan, Taiwan, and South Korea) have already agreed to
. use this system as their primary mesna of disseminating information about nuclear power status dudng the Y2K transition. The stuff has also been working with the President's Council ca. the Y2K Conversion, the Domesdainteragency Working Group, FEMA, DOE, NERC, and the information Coordination Center to ensure that information that the NRC obtains dudngj Y2K transition will be effe&d shared udth the Executive Office and with appropriate Federal i
i agencies.
i Countries in endier time zones, which will experience any Y2K-related problems before the U.S.
does, have been irtvited to provide information to this system in the quickest possible manner to enable reactor operators in participating countries in later time zones to avoid commnn-cause failures. To date,,this effort includes mainly Far Eastem countries which operate reuus designed by U.S. vendors, as well as some European countries, Canada and Mexico. The NR,C Office of Intemati:nal Programs is using its bilateral agreement ties to invite countries i
outside of the CNRA and intemational nodear organizations to participate in YEWS. Curre Japan, South Korea, Taiwan, several Westem European countries, Canada and Mexico have
' agreed to participate in YEWS.
YEWS is being developed by the NRC in cooperation with the Nuclear Energy Agency (N and the Intemational Atomic Energy Agency (IAEA). Recently, more formal co-ordination channels with the Intemational Atomic Eriorgy Agency (IAEA) were established and the IAEA*
provided comments on the system. Other discussions with the IAEA were focused ori the co-existence and co-ordination of YEWS with the IAEA's fax-based emergency notification s,ystem. A video conference with NRC, NEA, and IAEA to discuss YEWS is scheduled for the week of August 9,1999.
The YEWS prototype was first introduced to countries participating in the NEA's Committee on Nuclear Regulatory Agencies (CNRA)ln March 19g9 following an NEA sponsored intemational Y2K workshop in February 1999, which was also attended by regulators from the former Soviet Union and Central and Eastem Europe. The CNRA members are Belgium, Canada, Czech Republic, Finland, France, Germany, Hungary, IAEA, Japan, Netherlands, South Korea, Sp Sweden, Switzerland, United Kingdom, and United States.
The final YEWS model was presented in June. Its design is based on comments received from CNRA countries, U.S. reactor operators and utilities, industry groups, the Departments of State and Energy, and intamal NRC peer review. Access to YEWS will be controlled by password.
The system will reside on a secure server hosted by a national laboratory in the U.S.
The information received by the NRC through YEWS will be shared with licensees and the Departments of Energy and State, other Federal agencies as part of a coordinated Federal communication plan for the Y2K transition, and the Y2K information Coordination Center which is being organized by the President's Council on the Year 2000 Conversion.

CON.GRESSIONAL AFFAIRS The Senate 8pecial Committee on the Year 2000 Technology Problem invited Chairman Dieus to testify at a hearing focusing on the Year 2000 readiness of the electric power and gas industries. Due to the shortage of time before Corgiress departed for the August recess, the '
Cc.Wt'ee decided to tum the hearing into its first*cyber hearing." Testimony from the witnesses has been posted on the Web ratherthaa prese,nted in a hearing format. Other witnessesincluded FERC and NERC.
PUBUC AFFAIRS AND Y2K COMMUNICATION ACTMTIES An NRC press release titled ' Nuclear Power Plants. Report Safety Systems are Y2K Ready".-
i
~was issued on July 7,1999. Also, a summary oflicensee r6 ports on the status of Y2K readiness at nuclear power plants was placed on the.NRC Web site.
i
.i An NRC press release addressing the " Interim Policy Statement on Enforcement Discretion for Y2K" was issued on July 22,1999. The policy was noticed in the Federal Reaister on July 30, 1999.
The Cable News Network (CNN)' interviewed the staff in the NRC Opera' ting Center on July 7, 1999. The questions centered on the licensee responses to GL 98-01, Supplement 1.
The staff participated in a forum on "Y2K, Nuclear Plant Safety, and the Electric Power Grid."
The forum was sponsored by the George Washington University Y2K group and hosted by The Washington Post Company. Other participants were David Lochbaum of The Union of j
Concemed Scientists, Paul Gunter and Mary Olson of the Nuclear Information and Resource Service (NIRS), James Davis of the Nuclear Energy institute (NEI) and Paula Gordon of George Washington University. The discussions centered on the quality of NRC Y2K audits and
)
reviews, reliability and availability of electrical power in nuclear power plants, and the petitions for rulemaking filed by NIRS.
i As of the end of July, the NRC Web site continues to respond to approximately 3,000 page-requests per week for Year 2000 iriformation. Currently, the most fr,equently-requested pages are:
NRC Year 2000 Page 34 percent of Y2K requests Y2K Contingency Planning Page 11 percent'of Y2K requests i
Nuclear Reactors Y2K Page 9 percent of Y2K requests Y2K Status of Power Plants 6 percent of Y2K requests i
Y2K Frequently Asked Questions
,5 percent of Y2K requests NRC Y2K References Page 4 percent of Y2K requests During the month of July, the NRC Year 2000 Page was the 12th most visited page, and the NRC Y2K Contingency Planning Page the 17th most visited page, on the NRC web site. Two PDF files, the Y2K Contingency Plan and the Y2K Status of Power Plants, were the 3rd and 7th most downloaded files, respectively, on the NRC web site.

h Honorable P;ul D. Coverdell.
Regarding items (2) and (3), SNC completes a routine Farley plant shutdown from full operating power in about 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. it takes only a few seconds to manually or automatically shut down a nuclear plant in an emergency. These routine and emergency shutdown times are reasonable averages for all nuclear power plants. SNC plans to shut down Unit 2 for refueling and other maintenance, modify and test the software, and begin producing power agairs by about December 16,1999. We do not expect the Y2K issue to affect the safety of the Farley Nuclear Plant, Units 1 and 2, or their ability to supply electrical power to the national electric power grid.
Thus, we see no reason to shut down Farley Nuclear Plant, Units 1 and 2. Furthermore, we have undertaken an exhaustive effort to ensure that all nuclear power plants that are not fully ready for Y2K are on track to be Y2K ready before the end of the year.
Enclosed is the latest NRC status report on Y2K activities. We recently completed our onsite Y2K reviews at all 103 U.S. nuclear power plants and have confirmed that there are no Y2K-related problems which affect the performance of safety systems needed to safely shut down the plants. More Y2K information is available on our Website at httD://www.nrc.a ov/N R C/Y2 K/Y2 K R ea dv.html.
I hope that this information is responsive to Mr. Sherman's concerns. I am happy to give you any more details that you might need.
Sincerely, Original signed by FJMiraglia for/
