Annual report 2009 - Siempelkamp

Services around the reactor
Our physicists contribute an important part to the operation of nuclear power
plants which is also effective in all areas of nuclear physics. Among others this includes
services in the areas of incore fuel management, fuel disposal management, fuel
disposal studies, nuclear criticality safety and shielding calculations. Our competence
and operational experience does not only support reactor operators in all areas of
safety but also in regard to effi ciency. Here, our support targets primarily the increase of
the current yield and fuel effi ciency, the safe use of reprocessed Uranium and Plutonium
as well as the reduction of fuel element disposal amounts. Furthermore, our customers
also profi t from our software products ranging from core and fuel element storage
management to optimized fuel element loading to online simulations of the reactor
core.
Services in the area of nuclear physics in 2009:
sustained capacity utilization!
Just as in previous years, the order and delivery for incore fuel
management support resulted in high capacity utilization of our
physicists. We carried out the incore fuel management for both
units at the nuclear power plant Biblis and for both units at
Gundremmingen. For the nuclear power plant Krško in Slovenia
we carried out activation calculations in the course of the
decommissioning and dismantling cost calculations.
Many smaller service orders complemented our scope of services
in 2009. We monitored the nuclear criticality safety during the
refueling of the fuel elements at the nuclear power plants
Emsland and Grafenrheinfeld. The following orders are also noteworthy.
They ensure a utilization of our capacities in 2010:
• Delivery of the online core simulator for the nuclear power
plant Gundremmingen which was ordered in 2009. This
simulator will be used with the plant simulator at the Kraftwerksschule
(PowerTech Training Center) in Essen. We supplied
the computer hardware as well as application software that
has been customized for the use at the training center. The
advantages in the scope of the training at the school include:
more realistic, safer and more interesting training opportunities
for the trainers.

Incore fuel management on-screen
• Replacement of the fuel element information and reporting
software system (the order was received in 2009, completion
scheduled for late 2010) for RWE. This database system manages
the core and fuel element repository in nuclear facilities as well
as at interim storage locations.
• Another order we received in 2009 involves the support of the
physical department of the nuclear power plant Unterweser
during routing operating tasks. Our nuclear physicists will
provide support with calculations.
