Considerations in New Nuclear
Build Projects Specifics of Nuclear New Build
Projects:
● Technical sophistication
● Capital intensive, with all resulting
economical difficulties and
financial considerations
● Long development and
construction period
● Safety implications escalating
recently
● Need of specific infrastructure
● Establishment of National and
International legal framework
● Nuclear knowledge required
● Subject to public concern
Siting Considerations for
Nuclear Plant Life Cycle
A well-chosen site will: ● minimize the vulnerability of the nuclear power plant to external
hazards (both natural and human induced)
● have favorable attributes for minimizing all aspects of the impact to the environment from the NPP operation
● be able to accommodate many of the available nuclear power technologies
● consider the industry lessons-learned
● meet domestic and international requirements and
● lower site development costs.
The criteria for site evaluation should take into account all phases of the Nuclear Power Plant (NPP) life cycle, from site preparation to decommissioning and abandonment.
The NPP life cycle consists of siting, design, construction,
commissioning, operation and decommissioning.
● Siting and design basis definition take place about 8-10 years
before the plant commercial operation
● Safety reevaluation are made several times during the plant life
● Design basis reevaluation may determine the plant economical life
time by introducing a need of extensive NPP upgrades
● Deep and thorough initial process of design basis definition will
allow that plant economical life time coincides with the technical
one.
Justifiability of the initially defined design basis plays a
very important role in the subsequent plant safety reviews.
Siting Considerations for
Nuclear Plant Life Cycle
Work Related Considerations:
Quality Management
Any characterization and evaluation activity for siting, design
or construction of a nuclear power plant must be done so
following a Nuclear Quality Program.
A Quality Management System must be established and
implemented to control the effectiveness of site investigations,
assessments, and engineering activities for all aspects of site
work.
The QA program must cover organization, planning, work
control, personnel qualification and training, verification and
documentation of the activities to ensure the required quality
of the work.
Thus will assure that the results of the siting phase can be part of the overall design and licensing basis program for the nuclear installation.
Work Related Considerations:
Risk Management
The risk management and mitigation process
provides a sound basis for managing the project
preventive action objectives.
The risk management process is ongoing for the
life of the project, with the capability to identify
needed actions and risks evolution follow-up:
● Continuous analysis of external and internal risk
factors
● Continuous monitoring of project implementation
environment
● Interactions with the project main plans: Execution
Plan, Licensing & Permitting Plan, Stakeholders
Management Plan, etc.
Risk register shall be developed and maintained as a live document during the project implementation.
Program implementation strategy for a new nuclear
plant construction project shall consider the
complexity of the whole process and provide for a
reasonable schedule.
Sometimes decisions to proceed are made later than
anticipated, leading to compression of schedules.
As the first step in the process, the siting work may
then be accelerated in order to achieve a project
milestone.
This creates pressures for all parties involved,
including regulators and may require sequential work
to be performed in parallel and out of the normal
sequence.
Work Related Considerations:
Schedule Management
A key lesson is to schedule the work on a reasonable timeframe, so it can proceed in a normally established logical and sequential manner.
Lack of uniform international basis for Siting Process:
● Differences between the referent international practices
● Local regulations implications and synchronization
● Applicable international requirements
Lack of compatibility between the conventional permitting
processes and the licensing from the Nuclear Regulatory
Authorities.
Lack of experience in process practical implementation for
large nuclear projects
Interface between local level permitting regime and the
national level ones
Work Related Considerations:
Licensing & Permitting Process
Work plans and Work Schedule shall allow flexibility and shall be regularly adjusted to the real process
Work Related Considerations:
Configuration Management
Information gathered during the site evaluation
process will be used during the NPP design. This
information becomes an element of the NPP lifetime
configuration management.
Requirements/criteria used during the site selection
can come from many sources. They should be
identified and known throughout the nuclear power
plant life cycle, and it should be possible to see and
track how these are being followed.
Comprehensive data management system should be considered for implementation early in the nuclear plant life cycle, starting with siting characterization and carried though the following phases.
To evaluate and characterize candidate sites and confirm suitability for construction of an NPP in line with:
● National requirements
● International requirements
● Best industry practices
● Stakeholders expectations
To perform work in efficient and cost-effective manner and in a way that will establish the basis for future steps
To be able to address the fluid situations/considerations to minimize impact on the process:
● Evolving regulatory process
● Post-Fukushima changes
