Organisationsversagen immer wieder

in Einzelfällen ausreichen, auch die

ausgeklügeltsten ingenieurmäßigen

Sicherheitsvorkehrungen unwirksam

zu machen. Da bisher wegen der hohen

Anfangskosten Kernkraftwerke

bevorzugt in reichen und technisch

fortschrittlichen Ländern gehäuft

betrieben wurden, hat man dort auch

alle bezahlbaren Sicherheitsvorkehrungen

getroffen. Jetzt bauen

aber vorwiegend ärmere Länder neue

Kernkraftwerke, womit dann gerade

dort das Eintreten schwerer Störfälle

denkbar ist. Wegen der aber auch

dort wachsenden ausgeprägten

Risiko aversion wären zur Aufrechterhaltung

der nuklearen Option

voll abgesicherte, wenn auch teure

Abhilfen gerechtfertigt. Es dürfte sich

daher lohnen, System mindestens zu

planen und zu erproben, die unter

wirklich allen Umständen eine

Dispersion ausschließen.

Nuclear Power Plants:

2017 atw Compact Statistics

Editorial

At the end of the last year 2017 (key date: 31 December 2017), nuclear power plants were operating in 31 countries

worldwide (cf. Table 1). In total, 448 nuclear power plants were operating on the key date. This means that the

number decreased by 2 units compared to the previous year’s number on 31 December 2016 (450, which means the

highest number of units since the first start of an commercial nuclear power plant in 1956) due to first criticalities on the

one hand and shut-downs on the other. The gross power output of these nuclear power plant units amounted to

around 420 GWe*, the net power output was approximately 396 GWe. This means that the available gross capacity

was about 1 GW, i.e. -0,25 % and the net capacity about 1 GW below the previous year’s values of about 421 GWe gross

and 397 GWe net.

Three (3) nuclear power plants started (nuclear)

operation 1 in two countries in 2017. These units reached

initial criticality, were synchronized with the grid and

started commercial operation for the first time in 2017

(cf. Tab. 1): China: Fuqing 4 (1089 MW, PWR, CGO),

Tianwan 3 (1126 MW, PWR, CGO), Pakistan: Chasnupp-4

(340 MW, PWR, CGO). One unit was synchronized with

the grid and started commercial operation for the first

time in 2017: China: Yangjiang 4 (1086 MW, GO).

For the third time since the accidents in Fukushima

( Japan) two nuclear power units, Takahama 3 (870 MW,

PWR) and Takahama 4 (870 MW, PWR) resumed operation

in 2017 in Japan after a longer shut-down.

Five nuclear power plant units were definitively

per manently shut-down worldwide in 2017. In Germany

the unit Gundremmingen B (1344 MW) was shut-down

after 33 years of successful operation. In Japan the prototype

fast breeder reactor Monju (280 MW) was shut down

22 years after first criticality. In the Republic of Korea the

PWR Kori 1 (608 MW) was permanently shut down. The

BWR Oskarshamn 1 (492 MW) was shut down in Sweden.

The Spanish nuclear power plant Santa Maria de Garona

(466 MW) was permanently shut down after five years of

lay-up operation due to an applied for but not approved

prolonged operation license.

Three new projects started with the first concrete and

further build activities. In Bangladesh one new build project

started with Rooppur 1(1200 MW), India started the

new build of the third unit at Kudankulam (1000 MW) and

in the Republic of Korea one additional project started

with Shin-Kori 5 ( 1455 MW).

In total 56 reactors are under construction worldwide

in 15 countries. The total gross capacity of this projects is

about 61 GW*, the net capacity 58 GW, in other words the

number was lower (2) compared to the previous year number

due to the three operation starts, three new build projects

and the suspension of one project with two reactors.

Compared with the millennium change 1999/2000 this

means that the number of projects under construction has

risen, when 30 nuclear power plants were under construction

worldwide.

Two projects in the USA were stopped. South Carolina

Public Service Authority (minority partner of the project,

40 %) decided to stop the new build project Virgil C. Summer

2 and 3. Construction of two advanced pressurized

water reactors (APR 1000, 1080 MW) by Westinghouse

started in 2013. In March 2017, Westinghouse Electric

Company filed for Chapter 11 bankruptcy because of $9

billion of losses from its two U.S. nuclear construction projects.

SCANA (share in project: 60 %) considered its options

for the project, and ultimately decided to abandon

the project in July 2017 after the decision of its minority

partner.

Active construction projects (numbers in brackets)

listed are: Argentina (1), Bangladesh (1), Belarus (2), Brazil

(1), China (18), Finland (1), France (1), India (7), Japan

(2), Republic of Korea (4), Pakistan (2), Russia (7),

Slovak Republic (2), Taiwan (2), the USA (2) and the United

Arab Emirates (4).

In addition, there are about 125 nuclear power plant

units in 25 countries worldwide that are in an advanced

planning stage, others are in the pre-planning phase

( status: 31 December 2017).
