Objectives

Explore the fundamentals of nuclear HVAC design and commissioning including Radiation and non-radiation controlled area design principles, thermal and aeraulic calculations, equipment qualifications, main components design consideration and selection (fans, chillers, local air coolers), and case study.

Day 1

Section 1:

Safety and Landscape of nuclear power plant

Safety message, Landscape of nuclear power plant operation, and Ionizing radiation protection
measures
Introduction to main safety assessment applicable to nuclear ventilation and stakeholders (UK
and international)
Lesson learned from nuclear Accident and introduction to ongoing new build NPP and SMR

Section 2:

Nuclear ventilation fundamentals, design principle, and good practices from installation to
commissioning

Nuclear design, installation, commissioning, and operation sequences
Nuclear ventilation main functions in radiation-controlled and non-controlled areas: Containment
(Fire, radioactive substance), purification, cleaning, conditioning, comfort
Design requirement and ventilation architectures in radiation-controlled and non-controlled areas
Standard application: ISO-17873, ISO-1366, ISO-16170, etc.
Standard regulatory test and Equipment Qualification (EQ) principles and applicable codes
Thermal and aeraulic calculations’ basic principles
Ductwork Pressure loss calculation approach (ASHRAE), ductwork sizing, and fans selection
Cooling and Heating coils basic calculation principle
Optimizations during design phases
Installation basic rules and tolerances: cases to avoid and recommendations
Tests and commissioning sequence presentation and main criteria to fulfill till handover for operation
Basic operation and maintenance actions for safety important components: Fans, Fire & smoke dampers, chillers, Tight isolation dampers /valves, HEPA/iodine Filters, etc.
QUIZZES

Day 2

Case Study 1

Design of ventilation, cooling, and heating of a 3500 sqm building hosting:

Radiation-controlled rooms: Safety pumps and valves, tanks, glove boxes, etc.
Radiation non-controlled rooms: accumulators Battery room, I&C, and switchgear rooms
Design architecture (including static and dynamic containment, air & gas filtration,
cleaning, conditioning)
Thermal and aeraulic calculation resulting in main equipment selection: fans, AHU, chillers,
local air coolers, etc. (via Excel Calculation tools/macro)
Proposal of floor layout implementation of main equipment
Excluded from this study: Seismic calculation, equipment qualification, and Smoke exhaust
design

Case study 2

Proposal of commissioning plan for case 1 systems test and commissioning
Definition of sequence, acceptance criteria, operational and safety I&C functions
Proposal of test and commissioning execution instruction and results records sheets for fans, HEPA filters, Iodine Traps
