Aft Flashcards
CAIS VALVES
Aft of 64wtb, containment automatic isolation system, detects problems within RC and shuts and can be switched via MR
Supply return ventilation
Both sides port + STBD through every bulkhead
4 air handling units
Move air around
Square hatches
For loading stores via lilo chamber
By pass valves
For loss of hydraulics to open airlock doors
TIC
Thermal imaging camera for the 3 man teams to use when visibility is minimal
Vogs bottle vogs system RC
Valve operated gas system, uses nitrogen to open valves, because the RC can’t be contaminated with hydraulic oil from leaks/drips
Primary sampling sink RC
MAs and MEs transfer to health physics lab to take test samples
OXO valves
Used in connection with vent state red to purge reactor compartment, SN up and LP blower running
Plug door
Key in tech office on important key board
MAIN steam stop valves 401 402
When reactor is under pressure in the primary system, steam goes through MSSV to TGs and main engines to produce electricity.
APL bag
Checked before watch , extended hose, composite diagrams and tools
2 diesel exhaust masts
Diesel sea water outlet , top
Boundary cooling hose
Cools deck heads , one in elysor space
ATUs
Treats and cools air
CAMS HPL
Centralised atmosphere monitoring system, program different for methanol
Emergency core cooling system
Takes water from everywhere to cool core, takes away AFFF
Pressuriser
Keeps pressure
Make up system and pumps
Pumps in like a piston , coolant and pressure into primary system
Full leak protection switch
Primary system
Reactor , water under pressure, pressuriser keeps it under pressure and takes out any surge , passes through MSSV and transferred into secondary systems and into tube banks -TGs main engines , condensers then turn back into water and it goes to hot well and extraction pumps take it out the Hotwell and back into the feed pumps and they feed back into the system
MRS pedestal
Reactor scram switch FULL/partial
Battle short switch to remove limitations in case of torpedo evasion and floods to surface
AFF in detail
Av+b gets reduced to 8.6 bar, gets put into no4 reserve feed tank, splits into 2, half goes to AFF tank(455litres) half goes to the top of the tank, they mix via orophis plates which are like teeth
