Canister closure lid weld hydrostatic
pressure testing.
Water drain down and totalizing.
Vacuum drying and dryness testing.
Helium backfill and totalizing.
The E1000 VDS requires only a
single set of connections to the canister
for all of its processing functions (i.e.,
one set of boom lines to the vent and
drain ports, as well as thermocouple
connections to the MTC). Compared to
multiple separate pieces of equipment for
each function (e.g., hydrostatic testing,
vacuum drying, etc.), this configuration
greatly increases efficiency in system
processing.
Transferability
The MAGNASTOR
®
system was
licensed by the Nuclear Regulatory
Commission in 2009. It is available for
use by any commercial nuclear power
facility licensed under 10 CFR 50. The
lessons learned from field testing and
subsequent loading evolutions at Catawba
have already been incorporated into
NAC International’s generic operating
procedures for the MAGNASTOR
®
system. This data was used to successfully
load MAGNASTOR
®
systems at
McGuire Nuclear station in the summer
2013, followed by the decommissioned
Zion Nuclear Station in fall 2013. Any
subsequent user of the MAGNASTOR
®
system will directly benefit from the
lessons learned acquired during the
first-of-a-kind loading at Catawba.
These lessons learned have also been
shared beyond MAGNASTOR
®
users
via the NAC International Users Group
(NUTUG) and Electric Power Research
Institute (EPRI) committees. Beyond

MAGNASTOR
®
applications, the trend
of the industry is toward high capacity
storage systems that minimize the number
of individual loadings. Experience gained
by Duke Energy in this first loading of a
dry storage system with 37 pressurized
water reactor fuel assemblies is applicable
to other high capacity systems currently
in development and deployment. Duke
Energy routinely shares lessons learned
with other utilities through various fora
including the Nuclear Energy Institute
(NEI) Dry Storage Task Force, the annual
NEI Used Fuel Management Conference
and utility benchmarking activities.
System loading data from the E1000LT
VDS can be used for extended storage
studies and license renewal activities.
Such work should benefit all plants
engaged in used fuel dry storage.
