SPENT FUEL RACKS MODIFICATION This Job. Estimate is for a project which supports the long tem operation of Diablo Canyon Power Plant. This cost estimate.for the Spent Fuel Racks Modification includes the amount previously authorized and spent under VP&GM 73068, A & B and ED 2479.
PROPOSAL It is proposed that the existing Unit I and Unit 2 spent fuel storage racks be removed and replaced by high-density spent fuel storage racks to provide long-ters storage ci fuel off-loaded from the reactor., It is further proposed that the spent fuel 9001 cooling systems be modified to provide the additional
. cooling needed for the additional. stored fuel.
JUSTIFICATION 1.
Necessity e
The existing spent fuel racks are designed to store 1/3 of the core, in which is normally off-loaded during the annual refueling, and still provide sufficient storage space to off-load a full reactor core at any time, if necessary. The 1/3-core off-loaded during each refueling was intended to be shipped off-site for storage or reprocessing prior to the s) next refueling.
I C3 Additional on-site spent fuel storage will be required at Diablo Canyon because of continuing delays and uncertainties in Federal Government policy regarding implementation of programs fer off-site spent fuel y
,~
storage and reprocessing facilities. This delay will likely extend to 1998.
c.
2.
Alternatives a.
Replace existing fuel racks with high-density spent fuel racks installed before the first refueling outage.
b.
Defer installation of new high-density spent fuel racks until just i
before the second annual refueling.
c.
Install a new spent fuel pool with high density racks elsewhere on site.
d.
Install on-site dry storage casks for spent fuel.
e.
Donothing(i.e.,retainexistingr'acks).
3.
Analysis The alternatives are compared below. Table 1 compares the. costs of each alternative.

(.
High density racks installed before first refueling:.llation' risk Simple-H a.
installation in a dry spent. fuel pool minimizes insta and cost. The use of the existing spent fuel pool reduces the
-amount of, fuel handling and the associated risk of fuel damage and possible contamination.
b.
Deferred installation of high density racks: This requires a more i
complicated wet installation in a water-filled pool using several divers and' requiring rehandling of. the stored fuel. Installation time would be extended. inst ~t11ation costs would at least double, j
and the operation would become considerably' more complex due to diver radiation protection.
l t
Wet installation work is more complicated and imposes additional-limitations. This reduces the ability to modify the installation-in-response to unexpected problems and increases the potential for cost-l increases.
i o
Fuel stored in the pool at the time of installation would have to be h
moved several times in order to remove the existing recks and still keep the fuel submerged. 'TMs would also require heavy components m
to be moved above spent fuel which may require NRC waiver of H
existing requirements. This creates the risk of NRC approval delays as well as increased risk of fuel damage and possible contamination.
I
(.)
Several factors could increase costs more than anticipated due to C'
the deferred installation.
Rack vendors are in sharp competition now for a limited number of jobs. This is not expected to be the case.later because some vendors cannot justify retaining their current staff and may drop out of this market shortly reducing iy N
competition and increasing prices. Material prices are current C
depressed but are expected to increase.
c.
Additional spent fuel pool on site: The cost would be several times that for replacing existing racks.. Fuel handling charges would be i
much greater. It is not certain that permits could be obtained for building a new structure on site for long tem fuel storage. Since l
i l
fuel ' transfer to the new building would be necessary, additional risk of irradiated fuel damage would be created.
d.
Dry storage casks on site: The cost would be several times that for replacing existing racks. - Fuel handling and inspection costs would be much higher. Licensing risks would be created since no dry storage facility has been licensed to date.
i e.
Do nothing: The p1 ant could not be operated with a full core offload' capability after the second refueling (i.e.,24 years after
,I commercial _ operation) or until off-site receiving-facilities become available. The Federal Government is not expected to receive spent i
]
fuel for permanent disposal until 1998. This is not acceptable.

o 4.
Recommendation i
Replacing the existing racks, with higher density racks will assure that continued operation of the plant will not be dependent on off-site storage of spent fuel for at least 16 years and potentially for up to the design life of the plant (depending on final rack design, future consolidation of fuel, and average time between refuelings).
Deferral of installation of the high density racks would delay this expenditure by less than one year, would necessitate a much more complicated rack removal and installation, and would increase the installed cost.
The alternate storage methods (new pool or dry casks) are several times j
sore costly and are subject to significant licensing or permit issuance
]
uncertainties.
Sheet 6-NPG-041
(-}
Doing n'othing would prevent continued plant operation with full core offload capability after two end one-half years.
Consequently it is recomended that the high density racks be installed prior to the first scheduled refueling.
