� National position：energy demand (especially in developing

country, industrialization, urbanization, growing population),

environmental pressure, energy security, political consideration.

� Legal and regulatory framework : completed law and code

system, including national laws, ministerial ordinances and

regulatory guides.

� Nuclear regulatory authority: implement the NPP siting, design,

construction, commissioning, decommissioning, operation safety

review and supervision.

Key elements of nuclear energy deployment

� Nuclear technology: import (such

as turn-key project) or self-reliance

develop



� Human Resource: both technical and managerial trained and

experienced personnel as plant designer, researcher,

constructor, operator and regulatory supervisor.

� Fund: capital investment and financing, government encourage,

financial risk due to engineering uncertainty


� Site Preparation: site investigation, selection and evaluation

carry Feasibility Study (FS), Site Safety Evaluation and

Environmental Impact Evaluation, etc

� Electrical Grid: a basis for plant

size selection and development

scale



� Equipment & Fuel Supply (Supply Chain

Management): import or local manufacture

� Radioactive Waste: radioactive gaseous and

liquid treatment and discharge, packed solid

waste disposal

� Emergency Planning: onsite and offsite

emergency plan and procedure under nuclear

accident

� Public Acceptance: nuclear power basic

knowledge publicize, information openness,

keep communication

From 2008, China government initiated Large Advanced PWR Project

� As one of National Science and Technology Major Projects

� Aim to develop and build GIII passive NPP independently

1. China advanced PWR deployment Program

Assimilation and absorption

of AP1000

CAP1400 R&D Demonstration

project

CAP1700 R&D

Generic technology and

critical equipment and material

Large Advanced

PWR Project



Present Status:

� AP1000 introduction, digestion and absorption has finished.

� CAP1000 plant design and equipment manufacture has

realized localization, and used in several projects.

� CAP1400 R&D has almost completed. CAP1400 demonstration

plant is going to FCD early next year.

2. Experience to share

2.1 National energy policy

78.40%

17.08%

2.22% 2.30%

Power generation of the 2rd quarter of 2014

� To improve environment, optimize

energy structure and meet energy

demand, nuclear power is significant

option for China.

� Take advantage of energy police, get

greater policy support and financial

support on NPP R&D, construction

and operation (provide research

expenses and government subsidies)




2.2 Interaction with the nuclear safety authority

� Comply with nuclear technical policy. After Fukushima event,

NNSA publishes “Safety requirements of new nuclear power plant

in the 12th Five Year”, requires the new units must meet GEN III

safety standards.

� NNSA involvement in new plant R&D

• Safety Analysis Review

• Experiment witness

• Independent analysis

• independent experiment

CAP1400 IVR test witness

CAP1400 PSAR Review Meeting

CAP1400 CERT test witness



2.3 Extensive cooperation with nuclear industry

Domestic participants: 100+ organizations involved, covering:

� R&D institute

� Manufacturer

� Construction

� Utility

� Academic




International participants:


Westinghouse(US) provides design consultation

L&M (US) participates in PMS development

OSUs (US) participates in test verification

EMD(US) and KSB (Germany) participate in the development

of Reactor Coolant Pump

GRS (Germany)participates in engineering verification

Laboratories of OECD provide large amounts of test data

Corporate from US, Canada and Japan participate in

equipment material research and test verification




2.4 Standard Design

� Standardization for the System, structure, component, NI/CI design

interface and CI configuration as well as the common specification,

general technical requirement, and design management document.

� Scope of standard design include NI, CI and part of BOP, divide into

three types:

BuildingReactorBuilding

Auxiliary Building

Annex Building

Radioactive Building

Diesel Generator Building

System “A” type system: 48

“B” type system: 60 “C” type system: 13

Item Nonstandard item: 56

General Equipment:317

Structural Module: 84

Mechanical Module:53

Type A

Type BRecommended standardization

Type C

Site applicability design




2.4 Standard Design

� With envelop site condition

Standard site parameter Design Value

Atmosphere Temperature -40~46℃

Wind SpeedExtreme wind speed：65m/s

Tornado：134m/s

Seismic SSE=0.3g (applicable for the high seismic area)

Design base flood level Lower than plant elevation (dry site)

Ground Water level -0.6m Lower than plant elevation

Rain 525.8mm (1hr)

Snow / Ice 3.6 kPa

Site exclusion area ≥800m

CAP1400 standard design site parameter




2.5 Equipment localization

� For key equipment, set special research subjects to realize localized

manufacture. If necessary, carry out verified test.

� Equipment for competition:

generally 2~3 suppliers,

decrease risk and avoid

monopoly.

� The key and large-amount

materials must be localized.

� Build qualified supplier chain. China Equipment Manufacturing Base




2.5 Equipment localization - Gen III qualified supplier chain

� Gen III qualified supplier chain were basically formed.

� 88 Chinese companies were qualified.

� Covering mechanical, electrical, material, design and construction.

� Design analysis and test verification capability significantly improved.

2.6 Experience feedback management

� Establish experience feedback system

� Set manage organization

� Complete work procedure

� AP1000 self-reliance project experience

feedback

� Build AP1000 DCP implementation

mechanism of feedback to CAP design

� Build AP1000 E&DCR implementation

mechanism of feedback to CAP design

� Build experience feedback channel with

owners, constructors, AE, collect

improvement information.
