Docket No. 50-320 (Three Mile Island Nuclear
)
Station, Unit 2)
)
)
. AFFIDAVIT OF WILLIAM A. ViPROCHI I, William A. Verrochi, being sworn, depose and say that the following is true and accurate to the best of my knowledge and belief:
1.
My name is W:
am A. Verrochi.
I am currently employed by GPU Service Corporation and serve as Vice President -
Generation.
In this capacity I am responsible for the design and construction of all new generating facilities in the General Public Utilities Corporation (GPU) System, includirg Three Mile Island Nuclear Station, Unit 2 (TMI 2).
2.
TMI 2 has been under construction since Movember 1969, and is anticipated to be completed and ready to load fuel in July 1977.
3.
The current status of ccnstruction on TMI 2 is as follows:
a.
Erection of all major structures isGS 011 about 99 per cent complete.
b.
Installation and setting of all major pieces of mechanical equipment s tanc' ;
at aboct 80 per cent complete.
7.90424005C
- Installation of large bore (2 1/2" c.
in diameter and larger) piping is aboct 94 per cent complete; installation of small bore piping is abcut 82 per cent complete.
d.
In the electrical work: installation of electrical cable tray is essentially complete, 77 per cent of the conduit has been installed, 62 per cent of the cable has been pulled into place and 41 per cent of the electrical terminations have been
- made, e.
All associated transmission lines are completed and awaiting fi'hal cut in.
The TMI substation is completed.
4.
To illustrate the cost penalties associated with a suspension of construction of TMI 2 it is assumed the suspension would cccmence October 1, 1976 and be terminated December 31, 1976, the date when the Nuclear Regulatory Commission (MRC) is e::pected to have in place a new interim fuel cycle rule.
5.
The work planned and scheduled to be accomplished between now and December 31, 1976, is as follows:
a.
CIVIL (1)
Complate installation of Reactor Building post-tensioning system and remove tower cranes.
(2)
Pour Reactor Building moat wall and roof
'6 W -0 2 slab.
(3)
Pour internal shielding walls at Elevation 280 in the Reactor Building.
.. (4)
Pour Auxiliary Building penthouse roof slab.
(5)
Seal Control Building equipment access opening at Elevation 280.
(6)
Complete architectural work at Elevation 331 in the Cont rol Building.
(7)
Pour foundations for and set evaporative coolers.
b.
MECHANICAL (1)
Install reactor coolant pump restraitt clevises and restraint arms.
(2)
Complete final details of turbine generator erection.
(3)
Perform miscellaneous equipment setting and connection work to support systen turno er to start-up and test group.
(4)
Complete horated water storage tank.
(5)
Complete Reactor Building heating, ventil-lation and air conditioning system.
c.
PIPING AND INSTRUME"TATION (1)
Bring total completion of all large and small bore piping systems to about 96 per cent and comple';e system turnover require-ments for them.
d.
ELECTRICAL (1)
Complete installation of embedded conduit b r= 0^53 to evaporative cooler foundation.
(2)
Install control rocm lighting.
(3)
Complete installation of several miscellaneouc electrical control panels, cabinets and racks.
_ (4)
Bring total completion of conduit installation to about 97 per cent, of cable installation to about 87 per cent and of cable terminations to about 75 per cent.
(5)
Complete installation of Reactor Euilding penetrations.
e.
PRE-OPEFATIONAL TESTING (1)
Substantial effort in pre-cperational testing involving construction, start-up and test,and station operating and maintenance personnel xculd be carried on during this period.
None of the work described above involves environmental impacts o f any significance beyond those which have already occurred.
6.
The cost of the work planned and scheduled between now and December 31, 1976 is estimated to be $24.4 million, which is 3.8 per cent of the total estimated cost of the TMI 2 facility and represents an addition of 5.1 per cent to the total $477.5 million expended on the facility to date.
This planned and scheduled incremental work would have only minimal effect on the overall cost /
benefit balance already determined for this facility.
7.
Continued construction of TMI 2 during the period between now and December 31, 1971 would not foreclo.;e anf reason-able alternatives.
There are no alternative generating facilities that could be accelcrated to make up for any delay in completion of TMI 2.
The next new generating facility scheduled to be riaced in service in the GPU System after TMI 2 is Forked River Nuclear 1982.
Station, Unit 1, now anticipated to be placed in service in May 69--0.M
_ As a practical matter, GPU management would not make any decision committing to an alternative generating unit for TMI 2 between now and the end of 1976, by which time the NRC is expected to have developed and issued its interim rule on the fuel cycle.
Suspen-sion of construction.of TMI 2 would not preserve alternative courses of action that would be otherwise lost during this period.
8.
A suspension of construction of TMI 2 for the thir-teen week pericd from October 1, 1976 through December 31, 1976 would result in lay off of approximately 1,350 persons, which would impose severe financial and personal hardship on these persons and their families, and significant negative impact on the local economy.
9.
It is expected that a three-month suspension now would result in at least a five-month delay in the project construc-tion completion.
The principal reason for the additional two-month or more delay would be the expected loss of key management personnel, craft supervisors and workers who are thoroughly familiar with the project procedures, requirements and status.
Many of these key personnel would not return to this project.
Turncver in such persennel, particularly at this late stage in construction, would cause a substantial loss in labor productivity for a period ^f several months following a three-month suspension in activity.
Should the period of construction suspension be longer, this factor would play an even more important role.
10.
It the above discussed five-month delay in schedule shculd occur, it could be assumed to translate directly into a five-month delay in ccmpletion of construction and commercial operation of TMI 2.
These effects would be due primarily to the inflexibility inherent in the late stages of construction of projects of this com-plexity and magnitude and our view that the present constructicn d.T ~0? 5
_ l I
pace is reasonably close to optimum.
11.
A five-month delay in commercial operar. ion would add the following estimated costs related to construction of the project, which ultimately must be borne by the customers of the GPU System:
Additional labor-related expenses for a.
minimum work force retained during the three-month period of inaceivity including retraining, requalification and relocation expenses of retained and rehired work force, and extension of anticipated fixed overheads during the two additional months of active construction, amounting to approximately
$5.0 million.
b.
Maintenance during the period of suspension and extended need for construction activity support, such as construction office expenses, water, sewerage, telephone, and similar services and activities, amounting to approximntely $1.2 million.
Storage costs charged by suppliers for c.
equipment which otherwise would have been delivered over the three-month period, amcunting to S.2 million.
d.
Labor escalation due to delay in payments for the construction work force, amounting to $.2 millicn.
Incremental cost of loss of productivity e.
Off~O.T_6 during period following suspension, amountinc to $1.3 million.
_7 f.
Increase in AFDC due both to the three-n.onth suspension and the additional two months of delay in commercial operation caused by suspension, amounting to $14.7 million.
The total of these estimated increased construction-related costs is about $23.1 million, which comes to about $7.7 million additional construction cost for each of the three months suspension of construction assumed.
12.
A five-month delay in achieving commercial operation beyond the presently scheduled date of ".ay 31, 1978 for TMI 2 would ultimately result in increased replacement capacity and energy costs or about to the customers mf the GPU System of about $4 3.2 million,
$8.6 million per month for each of the estimated five mont.is of delay.
