HPLWR Phase 2 - Overview -
Objective
“The overall objective of the HPLWR Phase 2 project is to
assess the critical scientific issues and the technical
feasibility of the High Performance Light Water Reactor
(HPLWR) system with a view to determine its future
potential.”

alternatives in Finland, e.g. EPR (Göran Koreneff)
WP3: Safety (M. Andreani, PSI)
VTT contributions 9 person months:
Development of HPLWR model for the current three-pass design, as well as
the needed transient neutronics group constants (cross sections)

Malla Seppälä, Joona Kurki)
WP4: Materials (A. Toivonen, VTT)
VTT contributions 44 person months:
To select optimal materials for in-core and out-of-core applications in HPLWR
Produce general corrosion, SCC and creep data and model for database (Sami
Penttilä, Aki Toivonen)

GETMAT -Overview-
• The requirements defined for innovative nuclear systems are
• Sustainability and waste minimisation
• Enhanced economics, safety and reliability
• Enhanced proliferation resistance
• With respect to the current nuclear industry experience, demanding material-related
operational conditions can be envisaged e.g.:
•
•
•
•
High in-service and off-normal temperatures
High burn-ups
Long service life-time (~ 60 years)
Compatibility with new coolants
These conditions imply new challenges on structural materials.

GETMAT -OverviewVTT contribution:
Conclusions from HPLWR Phase 2 materials studies
Fuel cladding: wall thickness ~0.5 mm, Tpeak 620-630oC:
-F/M steels: high oxide growth rate, ~1.5 mm/year
-9%Cr ODS: still rather high oxide growth rate, 0.2-0.3 mm/year
-Austenitic SSs and Ni base: rather high oxide growth rate or
contains too much Ni
-PM2000 corrosion rate slow, but suffers from 475oC embrittlement
 PM2000 selected at this stage
Other core components (500oC peak temperature):
-F/M steels: too high oxide growth rate at least for thin walled
components
 austenitic SSs selected at this stage

GETMAT -OverviewVTT contribution:
Conclusions from HPLWR Phase 2 materials studies
Improved general corrosion resistance for F/M and
ODS steels needed:
-Increased Cr for ODS seels (>9% Cr)?
-surface treatments (Cr cladding of F/M steels)?
