Week 2: Technical Specifications Flashcards
What are the Technical Specifications?
The Technical Specifications manual is a legal document that defines plant variables, operating conditions, surveillance requirements, and administrative controls which are required to assure the health and safety of the general public.
What are the sections of Tech Specs?
Definitions
Safety Limits
Limiting Conditions for Operation
Design Features
Administrative Controls
What are Tech Spec Safety Limits?
Limits upon measurable plant variables, such as thermal power, neutron flux, flow rates, pressures, and temperatures, which assure fuel cladding and RCS integrity.
What are Tech Spec Limiting Conditions for Operation?
The conditions of the safety related components and systems necessary to either begin reactor operation or continue reactor operation.
What are Tech Spec Surveillance Requirements?
Tests, checks, calibrations, inspections, and samplings at appropriate intervals required to prove the operability of safety related equipment.
What are Tech Spec Design Features?
A description of the plant’s site and facilities.
What are Tech Spec Administrative Controls?
Requirements concerning the facility’s organization, management, procedures, record keeping, etc.
