Historical Background (1)

Year Event

1971 Institute for Nuclear Technologies (ITN) have been established;

1972 Nuclear regulatory commission (ISCAN-AC) has been set up;

1975 Nuclear safety regulation have been issued;

1976 Physical protection regulation have been issued;

1977 Institute for Nuclear Power Reactors (IRNE);

1980 Construction of Cernavoda NPP started with 5 units in the same time;

4

Year Event1982 Quality Assurance Law was issued;1983 QA Regulations started to be issued one by one;

1990 ISCAN-CAN was transformed in the National

Commission for Nuclear Activities Control (CNCAN);

1994 CNCAN/AECB – Canada Contract in place for 3 years

1996 First criticality of the Cernavoda #1 NPP; New Nuclear Act (Law No. 111/1996);

1997 Construction of Cernavoda U2 NPP stopped;

2001 The Law on third party liability in the case of

nuclear damages; Construction of Cernavoda U2 NPP restarted; New Physical Protection regulations in force;


5

Year Event

2007 CNCAN issued the Operation Licence for

Cernavoda NPP #2; CNNP #2 at full power.

2010 EC DG Energy positive opinion have been issued for Cernavoda NPP units 3&4 construction


6

Cernavoda NPP

Construction started in 1980 with 5 units;U1 - Full Power: December 1996;U2 - Full Power: September 2007;U3 - Full Power: 2017;U4 - Full Power: 2018;U5 – Project stopped.

7

Romania has two units in operation and two unitsunder construction, on Cernavoda site, a CANDU-6 type reactor

CNCAN regulatory approach is a prescriptiveorientated one

The Operating License is issued for 2 years

The two years license renewal cycle will takes intoconsideration the regulatory assessment on thestatus of the actions developed by the utility toimplement the regulatory requirements anddispositions

to review plant organizational structure andprocedures

to define license conditions, if any

CNCAN Regulatory Review Objectives

16

Phase "A": Non-nuclear tests for individual systems

Phase "B": Reactor physics tests

Phase "C": Integral tests for whole plant at various power level. Includes the process of reactor power run-up from 0 to

100% of full power. It starts with the completion of phase"B" commissioning

Phase "D": Conforms completion of commissioning phase. includes

the process of reactor power run-up at 100% of full powerto perform guarantee tests etc. Preparation for plantcommercial operation.

Commissioning & Licensing Process

Examples of CNCAN Licences

Conclusions (1)

Nuclear power program in Romania started in

60’s;

The integration factor of the foreign nuclear

technologies in the Romanian industry was

quite high;

CANDU 6 Nuclear Fuel Technology fully

implemented in Romania;

V d d R i l f l

Conclusions (2)

The Romanian Heavy Water Plant produce the

heavy water with high quality;

The national capabilities in the nuclear sector

are well maintain;

CNCAN approach in the regulatory business is a

prescriptive one;

Conclusions (3)

The main actors of the Romanian nuclear

sector promote a large international

cooperation;

The international cooperation is extensively

followed by Romania;

The IAEA Missions (OSART, IRRS, INSAR,

SEDO, SCART etc.) are well received by the

Thank you for your attention !
