BACKGROUND
At present, two nuclear units are operating in Argentina:
AtuchaI (PHWR-350 Mwe) and Embalse(Candu648 Mwe).
A new unit: ATUCHA II (PHWR-745 Mwe) is due to enter in
3
operation shortly (Expected in September 2011)
ATUCHA II project began in 1980 and was resumed in 2007.
The plant site is located 115 Km. from Buenos Aires.
ATUCHA II PLANT DESCRIPTION
ATUCHA II (pressurized heavy water reactor) utilizes heavy
water as coolant and m
oderator (independent systems). It’s
design was originally based on the MZFR Siemens prototype.
The plant is cooled by the Parana river.
4
It uses natural uranium as fuel. Exhausted fuel is replaced in
parallel with the plant in operation.
A containment building houses the nuclear systems including
a large dim
ension reactor vessel and two steam generators.

Plant systems m
odeling extended to two-phase flow
phenomena: Main and auxiliary feedwater, Turbine,
Condensate, Containment….using TRAC_RT.
Separate input basedecksand m

Control room instrumentation sometimes obsolete or
decommissioned (instruments unavailable)
Plant design documentation difficulties: old, under
development and changing (Plant under construction)
PROJECT DIFFICULTIES AND CHALLENGES (2/2)

development and changing (Plant under construction)
Operating plant procedures are being drawn up.
Validation. Unavailability of actual process data.
�Difficulties and challenges seem to be overcome
�Project schedule without delays (next May due delivery
of Class room trainer Phase 1)
�Customer soundly involved and orientated to be O&M
