( ,) also a member of the Edison Electrical Institute's Electrical System and Equipment Committee, which was involved with development and analysis of facilities equipment and wystems associated with transmission and generation. I was a member of the National Electric Safety Code Committee, American National Standard C-2 Subcommittee 8 which was responsible for reviewing code requirements for work methods.
Finally in 1979, I was a member of the adjunct faculty of the Nuclear Engineering Department of the Polytechnic Institute of New York, masters degree level, where I taught a course on generation economics.
U,,
- 9. Q. Are you familiar with LILCO's generating units and trensmission system and particularly with those facilities used to provide power to the Shoreham Nuclear Power Station?
A. Yes, I am, i
- 10. Q. How did you acquire that familiarity?
A. My previous experience in Electric System Planning was directly related to the design of the transmission system and the generation system.
I O
l l
I
C) s/ Specifically, that work included the design of the l
transmission system as it related to the Shoreham l Nuclear Power Station. I was also responsible on a project basis for the field installation of the i Shoreham related transmission projects.
- 11. Q. Are you sufficiently familiar with design and operation and configuration of the LILCO generation and transmission facilities to be able to discuss in some detail the means by which LILCO could provide a reliable source of AC power to the Shoreham Nuclear Plant under a variety of operating conditions?
A. Yes. With this question in mind, I have undertaken
() to analyze the LILCO system frcm a number of standpoints. First, I have examined all of the LILCO
! generating sources which could ce called upon to
- provide power to Shoreham. In this connection I have considered everything fcom our four large steam -
generation plants right down to the four 2.5 megawatt diesel generators that we are now installing at the Shoreham plant. I have considered these facilities in terms of their historic reliability and the numerous measures which we have undertaken to further enhance their reliability. As an example, we now I
6
1 g_) have a number of deadline, black start gas turbines which can be brought on line almost instantaneously.
Second, I have considered the configuration of our transmission system in order to determine the various i
routes by which we could deliver power to the Shoreham plant site, assuming a variety of operating conditions. I have also reviewed the measures which we have undertaken to enhance the reliability of our transmission system, and the reliability of the transmission system historically. All of this review has focused ultimately on the capability of LILCO to provide reliable AC power to the Shcreham plant site.
() 12. Q. Do you feel you are qualified then to discuss the factors which should be considered in determining the capability of LILCO to deliver a reliable supply of ;
AC power to the Shoreham plant?
A. Yes.
LILCO GENERATION
- 13. Q. Please describe the generic components of the LILCO power supply system which will provide AC power to the Shoreham plant.
A. In the broadest sense, those components would be the p V
power generation sources and the transmission. network facilities for transmitting power to Shoreham. Power generation sources would include those owned and operated by LILCO, such as oil fired steam generators as well as gas turbines, and the generating facilities of the regional power grids with which LILCO is interconnected.
- 14. Q. Please identify and locate generally the LILCO power generating facilities and the LILCO transmission network which you will be discussing in this 4
testimony?
A. Attachment 1 to this testimony is a reasonably rN r j ( ,) accurate ELECTRIC TRANSMISSION SYSTEM MAP which lo stes all of LILCO's generating and transmission facilities.
- 15. Q. Describe generally the LILCO power generating l
facilities.
A. LILCO's present generating capacity is 3,721 MW I
consisting of 2,240 MW of base load steam turbine b
units, 432 MW of mid-range and peaking steam turbine units and 1,049 MW.of internal combustion peaking units. The internal combustion units include both ,
1 gas turbines and diesel generators. Attachment 2 to this testimony is a schedule identifying all units and showing their location and rated generating capacity.
- 16. Q. With respect to the LILCO owned and operated power generating facilities, would you describe briefly 4
those facilities which are directly involved in supplying AC power to Shoreham when required?
A. Yes. As shown on Attachments 1 and 2, LILCO has 4 major steam generating stations. Each of these stations is equipped with a backup black start gas
, turbine to provide starting power under blackout
() conditions. As an example, Port Jefferson is a major i generating station witn twc 190 MW steam generating -
units and two 48 MW steam generating units. It also has a black start gas turbine and is located 11 miles from Shoreham.
The LILCO system also includes ten 50 MW class gas turbines at Holtsville. These are located approximately 15 miles southwest of the Shoreham site. Two of these are presently equipped with deadline, black start capability designed and installed specifically to support Shoreham. Three

( more will be Nguipped_vithl black st' art capability in ,
! April 1994. As further backup, there are three deadline black st' art gas turbines located at
!; Southold, East Hampton and, as statad earlier, Port Jefferson. Each of the three 20 MW class units can supply power through the 69 kV or 1.18 kV transmission facilities to Shoreham. At the Shoreham site, LILCO is completing the installat' ion of a 20 MW gas turbine with deadline black start capability. This will provide adequate AC power to Shoreham even" in the event that all transmission to the site is lost. As 4-
! an additional source of bac'k-up AC power, and to j
I
, allow further independence from the LILCO grid and independance from the Shoreham normal station service transformer and reserve station service transformer, LILCO is in the process of installing atz the Shoreham i
i plant site a block of four 2J5 b6f deadline black .
J start GM diesel generators. The output from these
! generators can be routed'directly.into:the plant's 4 i
kV buses by plant operators.

l I'
! 17. Q. Explain what is meant by the terms " black start" and F " deadline black start". l i .
l A. Black start means that when a loss of power exists f
i the system operator, from a local or remote location, i
can start a gas turbine to restore power. The term
! deadline black start means that the gas turbine i I recognizes through its own circuitry that there has been a loss of power and automatically starts without j the necessity for operator activation. l 1 ,
. LILCO INTERCONNECTIONS TO REGIONAL POWER GRIDS [
- t
- 18. Q. Is LILCO's ability to deliver power to Shoreham i limited to its own generating capacity? I i 1 l A. No. As noted above, the LILCO system is [
t interconnected to the New York Power Pool (NYPP) and 4
the New England Power Exchange (NEPEX). Through (
F these interconnections, LILCO has access to l
substantial additional generation resources. [
- i' i
- 19. Q. Please identify and briefly describe these interconnections.
l .
l A. The interconnection with the NYPP is made'through 4
three ties which are identified on the left end of i

Shore Rd/ 345 kV 581 839 1479 Dunwoodie The New England Power Exchange interconnection is a submarine cable beneath Long Island Sound. It is a 138 kV facility normally rated at 285 MW. - This interconnection is also shown at the top of Attachment 1, toward the middle. These interconnections, together with the LILCO generating capacity, form an integrated electric network for-providing reliable AC power to-facilities throughout the LILCO system, including the Shoreham plant.
- 20. Q. Do these interconnections enhance the ability of LILCO to provide reliable AC power to Shoreham?
A. Yes. This network, with its ability to respond rapidly to changing system conditions, provides a reliable source of normal AC power to the plant.

- 21. Q. What measures do these power grids employ to assure the availability of power when needed by one of the participants?
A. Since all members of the NYPP are required to maintain a reserve capacity of 18% over their peak demand and since the pool members generally do not experience peak demands at the same time, a minimum pool-wide 22% reserve margin is achieved.
Furthermore, the NYPP operates with enough spinning reserve to cover the loss of the largest generation source in the State. The New England Power Exchange utilizes similar reserve requirements.
- 22. Q. In addition to these interconnections, does LILCO have any additional backup power capability at its own generating stations in the event problems are encountered?
A. Yes. As noted above, there are black start gas turbines located at each of our four major generating stations and at other diverse locations on the LILCO grid. In addition there are automatic. load shedding procedures which, in the event of a disturbance, serve to quickly stabilize the LILCO grid. )
v'
~<
- 23. Q. When were these black start gas turbines installed and why?
A. After the blackout of 1965 these black start gas turbines were installed at our major generating stations in order to provide a rapid means for restoring AC power to both the generating stations and to the system as a whole. In fact, the restoration of service in 1965 had been successfully initiated utilizing the Southold Gas Turbine, proving the value of diverse gas turbine installations for rapid power restoration.
- 24. Q. Describe the load shedding procedures and what they
() accomplish.
A. The load shedding procedures provide an automatic means for removing load from the grid. This system f
operates on changes of frequency. If the frequency drops below a pre-set level (59.3 Hz), load shedding automatically begins. Thus, by automatically matching load to available generation, a balance between the load to be served and the generation 1
j available is maintained. In addition, the System i
Operator has the ability to reduce voltage which also decreases load. These methods prevent cascading outages on the system.
O l

- 25. Q. Since the blackout of 1965 has LILCO suffered any.
loss of its entire grid?
A. No.
a
- 26. Q. Has LILCO ever lost a substantial portion of its grid since 1965.
A. Yes, once. In 1979 there was an incident on the i system where the grid east of the Holbrook Substation i
was lost due to vandalism at one substation. The system was completely restored in just slightly over one hour. That restoration was accomplished without the benefit of the procedures that LILCO is currently implementing. If such an event were to occur today, I
() LILCO would be able to restore power to Shoreham within minutes by utilizing the various black start
< gas turbines available.
- 27. Q. Because of LILCO's interconnections with other~ power grids, is LILCO more likely to experience a problem or deficiency on its system as a result of problems experienced by other members of the grid?
A. No. This was demonstrated when Consolidated Edison 4 4 System experienced a blackout in 1977. LILCO's entire bulk transmission system remained on line and 1 '
O 1
I i 'e
() there was no interruption in service to the LILCO system.
1 TRANSMISSION LINKS TO SHOREHAM
- 28. Q. Describe how the Shoreham Nuclear Power Station is interconnected to the LILCO transmission network.
A. The Shoreham Nuclear Power Station is interconnected to the LILCO system through 138 kV and 69 kV circuits. The configuration of these facilities in the general area of the plant can be seen in Attachment 3 which is an aerial photograph beginning at the 69 kV switchyard at Wildwood, which is south of the plant, and extending north to the site of the plant itself. These facilities are also depicted schematically on Attachment 4.
Four separate 138 kV transmission lines serve the 138 kV Shoreham switchyard. This switchyard can be seen in Attachments 3 and 4, adjacent to the plant. Two of these 138 kV circuits emanate from the Holbrook 138 kV substation; one from the Wildwood-Riverhead 138 kV substations; and one from the Brookhaven 138 kV substation. These can be seen schematically in Attachment 1. ;
(
l
! l l
- 29. Q. Where is the 138 kV Shoreham switchyard relative to the plant?
A. This switchyard is approximately 1300 feet south of the unit itself.
- 30. Q. Do all the 138 kV circuits enter the 138 kV switchyard on the same right-of-way?
A. No. Two separate and independent rights-of-way are provided, each containing two of the four 138 kV circuits.
I
- 31. Q. Would you please describe the 69 kV circuits?
A. Three 69 kV circuits feed the Wildwood Substation
- which is approximately one mile south of Shoreham.
The three circuits emanate from Riverhead, Holtsville, and Port Jefferson and enter the i switchyard via two separate rights-of-way. The Holtsville circuit passes through the Ridge substation before going on to Wildwood. From the Wildwood switchyard, a single 69 kV circuit enters the site.
i l
l l
O -t'~
~
- 32. Q. Are the 69 kV lines in the same location as the 138 kV lines?
A. The 69 kV line from Wildwood to the Shoreham 69 kV
- switchyard has been placed underground in the vicinity of the 138 kV facilities from the 138 kV switchyard to the NSS transformer to maintain
! complete independence of supply between the normal station service (NSS) and the reserve station service (RSS) transformers. This provision minimizes the likelihood of simultaneous loss of supply to the NSS and RSS transformers by a common event.
- 33. Q. Are there any features of the 69 kV lines that
() enhance the reliability of the 69 kV circuits?
A. Yes. In the unlikely event that there is a failure of the underground 69 kV circuit supplying the
- Shoreham 69 kV switchyard or the underground circuit from the Shoreham 69 kV switchyard to the RSS I
transformer, there is a bypass 69 kV circuit 4
(bypassing the 69 kV switchyard) and running directly from the 69 kV overhead line from Wildwood to the RSS transformer. By utilizing this bypass circuit, power can be restored without having to repair the
- underground cable or route power through the Shoreham 69 kV switchyard.s O 4 l
l
( 34. Q. How long would it take to place this 69kV bypass in
, s_ ,/ i service?
A. Approximately four hours. We have not actually performed this operation but this is a conservative estimate.
- 35. Q. Are you familiar with the requirements of GDC 17 with respect to the number of offsite circuits required to serve a power station?
1 A. Yes. It states in part, that: " Electric power from the transmission network to the onsite electric distribution system shall be supplied by two physically independent circuits (not necessarily on
() separate rights of way) designed and located so as to minimize to the extent practical the likelihood of j their simultaneous failure under operating and i
2 postulated accident and environmental conditions. A switchyard common to both circuits is acceptable.
4 Each of these circuits shall be designed to be 4
available in sufficient time following a loss of all i
- onsite alternating current power supplies and the other offsite electric power circuit, to assure that specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary i
l are not exceeded." 10 CFR Part 50, Appendix A.

O)
(_, 36. Q. Can you compare those requirements with the transmission network facilities presently serving Shoreham?
A. Yes. At Shoreham, there are four circuits on two separate and independent rights-of-way, each circuit containing tv: of the four 138 kV circuits as mentioned previously. The 138 kV switchyard is arranged in a two bus configuration with circuit breakers and switches arranged to permit isolation and/or repair of either bus section. This configuration is shown schematically in Attachment 4.
This configuration permits continuation of 138 kV power supplied from separate rights-of-way even in the event a bus section is out of service. A common J
bus section between these two sources feeds the NSS transformer. In addition, a 69 kV circuit enters the plant area and proceeds to a separate switchyard.
- 37. Q. Do the number and geographical dispersion of these 138 and 69 kV circuits enhance the reliability of LILCO's ability to provide AC power to Shoreham beyond the 2 circuit requirement of GDC 17?
A. Yes. GDC 17 would permit the 138 kV and 69 kV circuits to enter the plant site as above ground 1
g J
) circuits in a common right of way. In fact, the 138 4
kV and 69 kV circuits enter the plant site via entirely separate rights-of-way. Furthermore, the 69 kV circuit is underground.
Both.the 138 kV and 69 kV lines form part of the LILCO network transmission system. The dispersion of these facilities provides redundant sources and lowers the possibility of the loss of more than one of them. The utilizaton of multiple lines and separate switchyards, and thus the limited exposure i to common failures, enhances the reliability of offsite power.
i O TRANSMISSION NETWORK RELIABILITY
- 38. Q. Does LILCO employ design criteria for its transmission lines with respect to their ability to withstand high winds?
A. Yes. The transmission system is designed to withstand winds in the range of 100 to 130 m.p.h., in excess of National Electrical Safety Code (NESC) requirements.
l l
1
() 39. Q. Has LILCO's transmission system been adversely impacted by tornadoes in the last 20 years?
A. No.
- 40. Q. Has LILCO's transmission system been adversely impacted by earthquakes in the last 20 years?
A. No.
- 41. Q. Has LILCO's transmission system been adversely impacted by hurricanes in the last 10 years?
A. Although there may have been outages to individual lines during major storms, there have been no outages of such magnitude as to cause the loss of power to a facility such as Shoreham. This is true because the transmission system is a network system, that is, having multiple sources and transmission paths.
- 42. Q. Is LILCO going to undertake any additional safeguards to limit even further the possibility of an impact i from weather phenomena?
A. Yes. This subject is addressed in the testimony of Mr. Museler which details specific act i ons to be i
taken when certain weather warnings are received.
i I
l i
i l
(
() 43. Q. Who will be responsible for receiving such warnings?
A. The warnings will be received by the System Operator of the Electric System Operations Department.
- 44. Q. How will they be received?
A. LILCO receives such warnings from the National Weather Service as well as a contracted weather <
1 service at the Electric System Operations center in Hicksville.
1
- 45. Q. What will the Electric System Operator then do?
1 A. He will notify the plant operator.
- 46. Q. How will he know to do that?
A. He will know so by procedure.
(}
- 47. Q. Is Attachment 5 a copy of the procedure requiring the weather information to be conveyed?
A. Yes, for all operating plants.
i
- 48. Q. What will be then done?
A. The plant will be shut down based on commitments 1
3 found in William J. Museler's festimony.

() 49. Q. Given your experience and knowledge of LILCO's system, are there other natural phenomena which might occur on Long Island and which conceivably could
- impact on LILCO's transmission system?
A. There are other natural phenomena which could impact pieces of the LILCO system. However, historically, these phenomena have not had a significant impact on the system.
- 50. Q. And what would those be?
A. The first would be ice storms. The major impact of ice storms is generally on the distribution system.
The low voltage lines are susceptible to interference i
() from broken trees. Such a possibility does not generally exist with the 69 kV and 138 kV j transmission network because all of these facilities i
- are maintained on cleared rights-of-way. The second i phenomena is lightning. There have been instances where a lightning strike on a transmission line has momentari'y caused that line to trip, however there are reclosing facilities (manual and/or automatic) on such lines which re-energize the line after the
! initial trip.
l l
j
l .
l
- 51. Q. Does LILCO have the capability to repair damaged i transmission lines should such repair become l
' l j necessary? i A. Yes. LILCO routinely designs, constructs and !
i 4
maintains its own transmission facilities. That is, it does not contract out these tasks to outside I constructors. As a result LILCO is intimately familiar with these facilities and maintains a state i-j of constant readiness with a large force of trained personnel to restore transmission facilities which j may become inoperative for any reason. These trained i
crews are available twenty-four hours a day to
~'s respond to emergency conditions. In order to assure (O prompt responsiveness tor the lines serving Shoreham,
]
- LILCO is undertaking extraordinary measures to l
! preplan such an operation. This includes measures !
- such as pre-assigning poles and hardware and storing
( ,
e this equipment at optimized locations as well as conducting additional training of overhead lines
- personnel.

I
) 52. Q. Using such measures, how quickly can LILCO restore the transmission lines?
A. Using these measures LILCO can restore a mile of 69 kV transmissions facilities within twenty-four hours.
1 While it is not anticipated that such extensive damage would occur on any one transmission line, this capability provides a benchmark indicating the l expeditous manner in which LILCO could restore !
facilities. f 1 53. Q. Now assume that LILCO were to suffer a simultaneous loss of its base load and mid-range steam generating 8
units as well as its interconnections to other grids.
() Would LILCO have a way to provide AC power to Shoreham under this blackout condition?
i i A. Yes. It could be provided from a number of separate sources. They are: the Holtsville gas turbines, the East Hampton gas turbines, the Southold gas turbine, l the Port Jefferson gas turbine, the Shoreham gas turbine, or the Shoreham GM diesels. All of these i
facilities have black start capability.

T HOLTSVILLE GAS TURBINES
- 54. Q. Would you please describe the gas turbines at )
i l Holtsville. !
l A. The LILCO system includes ten gas turbines at
- Holtsville, two of which are presently equipped with i
- deadline black start capability, and three of which ,
- will have black start capability designed and I
- installed to support Shoreham. All five black start ,
i j gas turbines are under the control of, and can be l started by, the System Operator. Power from these gas turbines is capable of being supplied to Shoreham ,
i
- through various transmission paths ultimately leading
! to any of the four 138 kV lines or the three 69 kV i
i lines to Shoreham, as depicted in Attachments 1 and
+
} 4. Any one of these five units at Holtsville would ;
J be sufficient to supply power to Shoreham.
j 55. Q. How far is Holtsville from Shoreham? f a t j A. About fifteen miles, i ,
- 56. Q. How quickly can power be restored to Shoreham from Holtsville?
t i
i A. Under simulated conditions, actual tests have shown j
that power can be restored to Shoreham from j Holtsville in six minutes. !

A. The System Operator in close coordination by telephone and/or radio with the Shoreham Control 1
Room, deliberately isolates these gas turbines so that the system appears to be in a blackout mode. A ;
unit automatically starts and the System Operator then clears a transmission line express to Shoreham.
i LILCO's Emergency and Unusual Procedures Manual i
dictates that implementation of this procedure is .
the paramount priority for the LILCO System Operator

A. This testing will demonstrate the starting reliabil'ity of the gas turbines at Holtsville as well as the ability of the System Operator to restore i power to Shoreham on a rapid basis, i
- 61. Q. Are the Holtsville gas turbines designed to withstand earthquakes?
A. Although not specifically designed to withstand l earthquakes, as noted in the attached letter from United Technologies (see Attachment 7), the ,
Holtsville (Holbrook) units are able to withstand a 0.2g horizontal load. However, they may not operate f
j i
() through that load, but would be available to operate following such a load.

() 63. Q. Does the Southold gas turbine provide sufficient power to Shoreham to meet emergency AC power needs?
A. Yes. It is a 14 MW unit.
- 64. Q. Through what transmission lines would power be !
supplied from Southold to Shoreham?
A. Power would be supplied from Southold to Shoreham 3
first through the 69 kV lines to Riverhead where i
routing to Shoreham could continue via 69 kV or 138
- kV lines.
i 65. Q. How quickly can power be restored to Shoreham from i
Southold?
A. In ten minutes.
- 66. Q. How is this accomplished?
, A. This is again accomplished by procedures implemented 1
by the System Operator.
4 67. Q. Who initiates this procedure?
! A. It is up to the System Operator to initiate such a I
procedura. His prime responsibility in the event of
! a blackout is restore power to Shoreham. He has I
various means available to him. He has Holtsville, ,
Southold, East Hampton and Port Jefferson. He will 4
1
\/ utilize at the time the best means available to him to restore power to Shoreham in the shortest possible time. This may involve the simultaneous use of all means available.
- 68. Q. Is the procedure written for restoration of power? l A. There is a procedure which says that the priority of restoring power to Shoreham is the prime consideration (see Attachment 6). The specific procedures for the individual units are in the process of being finalized. The most recent draft of these procedures for all of the units, including
- Southold, is included as Attachment 8. It should be
() noted, however, that the System Operator, and the district operators who work for him, are trained to react to any transmission system problem on an ad hoc basis. Thus, procedures which are specific to the various units will only enhance what is already a i very reliable mechanism for restoring power. The only procedure really necessary to be established is <
! that Shoreham is the first priority for restoration.
That procedure has been established.

() 69. Q. Has the testing of Southold as a restoration source of power to Shoreham been done?
A. Not at this time.
- 70. Q. Will it be tested periodically?
A. Bi-weekly the gas turbine will be tested as to its ability to start and accept load; however, the 69 kV system which would be used for the routing of the gas turbine is an integral part of the transmission grid and as such it is not anticipated that such a test would be conducted as frequently as, for example, Holtsville. However, a test will be done at least once a year.

EAST HAMPTON GAS TURBINE
- 71. Q. Where is the East Hampton gas turbine located?
A.
The East Hampton gas turbine is located on the south fork of Long Island, southeast of Shoreham, a distance of thirty-five miles. on an independent transmission system from the other gas turbines as ;
far as Riverhead. From Riverhead, power from both l 1
the East Hampton and Southold gas turbines, could be transmitted to Shoreham along several alternate 59 kV and 138 kV routes available to be used into Shoreham.

l l
() 72. Q. Does the East Hampton gas turbine provide sufficient power to Shoreham to meet emergency AC power needs?
A. Yes, it is a 20 MW unit.
c
- 73. Q. How quickly can this restoration be accomplished?
A. In about fifteen minutes.
- 74. Q. Who initiates this procedure?
A. Again, it is at the discretion of the System Operator as mentioned above.
- 75. Q. Is the procedure written?
A. The most recent draft is included in Attachment 8.
- 76. Q. Has the procedure been tested?
A. No.
77 Q. Will it be tested periodically?
A. The unit start will be tested on a bi-weekly basis, demonstrating its ability to start and pick up load.
However, the express isolation of a transmission line to shoreham is not presently contemplated on as regular basis as the Holtsville units, but will be done on an annual basis.

l ; O i
'l (O _s/ 82. Q. How much time would elapse while the determination
- was made as to which source would be used to restore i power to Shoreham? ,
- A. Only seconds in most cases since the gas turbines ,
would have started automatically. The System i Operator would know of their availability, and he i
would know the status of the various links of the transmission system. He would utilize several
- sources simultaneously to route power to Shoreham. ,
l i
There is an individual procedure for each unit. It j is the operator's expertise in operating the power j system that enables him to effect the overall
! integrated restoration operation and to do so almost j immediately.
i j SHOREHAM GAS TURBINE 1
- 83. Q. Whrt about the gas turbine on the site at Shoreham.
j Would you describe that please? .
A. Yes. It is a nominal 20 MW gas turbine (17 MW summer rating, 20 MW winter rating) located in the 69 kV 4
l switchyard at Shoreham. It is connected to the 69 kV i
i bus through a step-up transformer.

E i
- 84. Q. How is it connected to the plant electrical system?
A. The reserve station service transformer is connected i to that same 69 kV electrical bus.
- 85. Q. Is the gas Shoreham turbine now operational?
A. Yes.
i
- 86. Q. Does it provide sufficient electricity to meet ,
Shoreham's emergency AC power needs?
A. Yes.
- 87. Q. How quickly can power be restored to the plant using this gas turbine?
A. Within three minutes power can be restored to 4 kV emergency buses shown schematically on Attachment 9.
1
) 88. Q. Is there a procedure to accomplish this?
A. Yes. The procedure is practically automatic. Upon '
l loss of a voltage to the 69 kV bus, the 69 kV bus j automatically isolates from the system, automatically sheds loads on that bus, the gas turbine
! automatically starts, closes into the bus and i therefore supplies power to the RSS transformer. On the low side of the RSS transformer are breakers to l the three emergency buses (see Attachment 9). Those l 1

I i rN i ( ,) 94. Q. Do you have any indication now of the reliability of this gas turbine? r A. Yes. With its newly-installed low pressure air start
! system and fuel control system, this gas turbine is virtually identical to the gas turbine at East !
Hampton which has an operational availability of 97.9%. Its starting reliability is 100%.
- 95. Q. What is the difference between this unit and the East i Hampton unit? I i
l A. The difference is that in the East Hampton unit in r
j the first stage of compression there is additional I cooling'which allows for a slightly higher megawatt 1
() output. To the best of my knowledge there are no other substantive differences.
- 96. Q. Do you have any indication as to how this gas turbine would react in an earthquake?
j A. Not specifically. However, the 20 MW gas turbine
- should be able to fulfill'its function even after a seismic event. It is a Turbo Power and Marine (United Technology) gas turbine. There are no substsntive differences bet' ween Turbo Power Marine l
gas turbines specifically designed in a:cordance with 4 -
O I the seismic building code and the 20 MW unit at Shoreham or, as mentioned previously at Holtsville.
The code requires machines withstand a .3g horizontal acceleration. Accordingly, TFEM has assured LILCO that the 20 MW gas turbine would be structurally sound during a seismic event at Shoreham which would
, exert only a .2g horizonta1' acceleration and a .113g vertical accerleration. A letter to this effect is included as Attachment 7.
- 97. Q. Describe the capacity of the fuel tank for this gas turbine.
A. The capacity of the fuel tank is 972,931 gallons.
This capacity would provide a running time at full j output of the gas turbine for more than 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> or 1 !
20 days.
i l 98. Q. Is the fuel tank seismically qualified?
i A. No.
- 99. Q. What is LILCO's doing to compensate for the inability I of the fuel tank to withstand an earthquake?
A. LILCO will provide a 9,000 gallon fuel oil tank truck j
,! on site at all times on a standby basis to provide i fuel to the unit.

() 2.5 MW DIESELS AT SHOREHAM 104. Q. Suppose, following a system-wide blackout, none of the gas turbines operated. Could LILCO provide the necessary AC power to the site? l A. Yes. LILCO is installing a sixth AC power source. i In the unlikely event that all of Shoreham's normal design sources of AC power were lost simultaneously, and that in addition the black start gas turbines at Holtsville, Southold, East Hampton, and Port Jefferson as well as the 20-MW gas turbine at Shoreham were also to simultaneously fail at precisely the same time, LILCO is installing at Shoreham a block of four 2.5 MW General Motors EMD Deadline Black Start mobile diesel generators, Model No. 20-645E4B. These genefators will be directly connected to the plant's 4 kV bus network.
105. Q. Where are these to be installed?
A. They are presently being installed on the southeast corner of the Shoreham Plant site.
- 106. Q. How are they connected to the plant's electric system?
l s.)
w.. -, - - .
() A. As noted, they are connected to the plant's 4 kV bus network, which in turn will provide power to the emergency 4 kV buses. This can be seen on Attachment 9.
107. Q. Aside from their redundancy, what additional safeguards do these diesels provide over and above the gas turbines?
A. These diesels provide the ability to get power directly to the plant's 4 kV buses, bypassing both the reserve station service transformer and the normal station transformer. Thus, in the extremely unlikely event of a simultaneous loss of both
() transformers, adequate power could still be supplied to the 4 kV buses. These generators will be able to provide power to the plant's emergency systems within i 30 minutes of the loss of offsite power. The diesels start deadline and are ready to accept load within ten minutes. ,
108. Q. Would you describe the machines? l A. As noted, the machines are each 2.5 MW. They are General Motors EMD diesels and have been in service since 1967 at New England Power in Lynn,
/'~T O
O l
Massachuesetts where they were utilized for peaking l capacity.
109. Q. Were these diesel units purchased from The New 1
England Power Company?
A. Yes.
110. Q. Did you obtain information from The New England Power Company with respect to the operating history of these units?
A. Yes, we obtained sufficient information to know that the units have had an extremely high record of starting and operating reliability.
() 111. Q. How many of these GM diesel generators are necessary to power the plant's emergency system?
A. At five percent reactor power output, one diesel generator unit provides sufficient power to run the two redundant ECCS subsystems, either of which is sufficient to cool the core.
112. Q. How quickly will these diesels be able to accept load?
A. Within ten minutes.
O 1 , s
)
O 113. Q. What is the mode of operation of these diesels?
A. On loss of voltage, these units wiil automatically start up and provide power to an open breaker on the 4 kV bus, Breaker ll-1B. That breaker will be closed by a Plant Operator, as will the breaker to the emergency buses, and thus power will be routed to those emergency' buses. The total time required to deliver power from the diesels to the emergency equipment is no more than 30 minutes from the initial loss of power.
114. Q. Are these diesels started concurrently with the numerous offsite gas turbines?
) A. Yes.
115. Q. What is LILCO's fuel storage capacity for these diesels?
A. LILCO's fuel storage capacity is about 9,000 gallons to be provided in a fuel tank truck 116. Q. How long can the diesels operate on that amount of fuel?
A. At full load for about nine hours; at quarter load for about 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. A second truck will be onsite available when the first becomes empty.

' TURBO POWER 400 Wsin street East Harffore. Connecticut DetDe 303/h4321 March 1.1984 l Long Island Lighting Company 175 East Old Country Road Hicksville, NY 11801 Attention: Mr. Richard Zambratto Gentlemen:
In response to your request for information relative to the seismic resistance capability of TPM FT4 units, the following is offered.
Prior to 1975-76, the structural design of FT4 units incorporated a variety of NEPA, ANSI, ASCE, and AWB specifications, but did not incorporate specific seismic load requirements. Beginning in about 1975, we initiated design incor-poration of the " Universal Building Code" which includes a 0.3g horizontal load requirement, but no vertical load requirement.
The " Universal Building Code" requirement is that the structures and equipment be able to withstand a 0.3g horizontal load, but does not require that the unit operate throuch that load. We do not know whether installed protective relays and the Rowan relays installed in the FT4 sequencer units could withstand such O. a load without tripping.
Even though the structural design of pre 1975-76 units, which includes the West Babylon and the Holbrook units, did not incorporate the 0.3g horizontal load requirement specifically, it is our opinion that all those units would with-stand the 0.2g horizontal and 0.113g vertical load requirement you mentioned and still be operable. The concern about operating through su:;h an event with-out tripping relays would still apply.
There is one other minor point worth mentioning: inaPowerPac(oneengine, one generator), the engine / generator coupling is rigid and provides a fixed re-straint formovement.
significant the generator retorPac In a Twin which would absorb (two engines, any axial one generator , the "g")
engine load / without generator couplings are the flexible Bendix type which could allow some genera-tor rotor axial movernent due to imposition of horizontal load. This axial movement might compress one flexible coupling in the direction of movement and impart a momentary impact load on the power turbine thrust bearing. This remote possibility could result in a peening of the bearing ball / races leading to an eventual failure of the bearing. The restraining stretching action of the opposite end coupling makes this a minor concern.
The gas turbine itself is designed to withstand much higher "g" loads, due to severe flight and military shipboard blast load requirements in the 5-10g range.
