Costs of continued operation are 1/5 of construction costs

Costs of coal is increased approx. 1.2 billion USD a year as of 2015

1.2 Billion USD Alternative

There is a reduction of carbon dioxide as about 11,000 ton a day in case of Wolsong unit 1.

36 Million USD

Additional costs of carbon dioxide is increased approx. 36 million USD

a year in case of stopping Wolsong unit 1.

• Authority Screening • IAEA SALTO program • Authority Approval

• Huge refurbishment during 2 times overhaul • Refurbishment after licensing to prevent

invest in advance

Continued Operation

03

• Demand for Information Disclosure

from National Assembly,

Environmental Groups, NGOs

• The summary of application

documents(PSR, LER, RER) are

submitted to the National Assembly

• After the regulatory review is

completed, accessible for reading to

the general public at a specific place

(some information on securities,

Intellectual property rights and

trade secrets are masked)

Wolsong unit 1

• Established legal “Aggressively

open to the public(’16.6.30)

• The full of application documents

(PSR, LER, RER) will post internet

home-page(NSSC)

• After the regulatory evaluates

the application documents suitability

(some information on securities,

Intellectual property rights and

trade secrets are masked)

10 Units in Kori Site

Domestic Regulation

- Site Evaluation : To be installed in a place that does not affect other NPP in the same site for geology and earthquake, meteorological conditions, multiple unit NPP etc.

- No shared System : Relevant SSC(Structure, System, Component) important to safety

- Requirement 17 : Internal and external hazards IAEA SSR-2/1

- Requirement 33 : Safety systems and safety features for design extension conditions of units of aa multiple unit nuclear power plant

The design shall take account of the related regulations of a multiple unit NPP such as no shared system, site evaluation etc.

NSSS Evaluation

Criteria of Regulation

The number of population in EPZ : 3,823,266 persons (Busan, Ulsan) Operation & commissioning Units (8) + Construction Units (2)
