Annulus Grouting
Bulk fill grout will be used to fill annulus
Grout introduced into annulus through the East and West Risers
Initial filling of duct through ventilation inlets is not required (lower portion of duct will fill through open registers during bulk annulus fill)
Vertical sections of annulus ducting (inlet and exhaust) will be filled to grade level after bulk annulus fill is complete

Grout Testing Protocol
Grout Truck Arrival and Check-in:• Every Truck
Batch Tickets (Multiple Verifications)― Grout mix― Timing < 90 minutes― Revolutions < 300― Point of delivery water additions
• Daily First Batch & at least one truck after first
100 cubic yards― Molding Cylinders (7)― Compressive Strength (7 and 28 days)― Slump flow― Temperature― Unit weight/yield― Bleeding of grout― Air Content
• Additional testing frequency as determined by Construction Discipline Engineer (CDE)
Video of Grout Placement:• Continuous during grout placement

Equipment Fill
Equipment fill grout will be prepared in small batches
SRR personnel pre-mix dry ingredients by weight
Water is combined with the dry materials as required, mixture is allowed to hydrate with low shear mixer
High shear mixer engaged to finish grout mixing and thin the grout
Grout is metered into equipment by gravity via hose and funnel
Equipment has high point vent that collects overflow indicating filling complete

Cooling Coil Fill
Cooling coil grout is prepared using a commercial grout skid
Dry ingredients are premixed at vendor facility and delivered in a Super Sack®
SRR personnel batch a fixed amount of water with the contents of the Super Sack® (i.e., dry materials) and mix the contents
Pump is used to meter grout into cooling coils
Totalizer at flow meter provides real time quantity of grout added
Intact cooling coils will be grouted from the coil inlet. When grout is visually detected at cooling coil outlet, additional grout shall be introduced for a prescribed volume
Grout/flush water interface volume from intact coils will be collected and disposed of separately
Coils having guillotine failure were previously flushed, coils will be grouted from each end (inlet and outlet) into the waste tank

Tank 16 & 12 Field Observation
• H-Tank Farm is a property protection area, no security escorts required for uncleared personnel within area.
• Personnel involved in tour should stay in contact with designated SRS personnel in order to provide instruction in the event of a need to shelter or evacuate the work area.
• During grouting operations, Grout Test area and truck unloading area is considered a construction work zone
• Construction work zones at a minimum require hard hat, side shield safety glasses and sturdy work shoes.
• Personnel requiring access to these work areas will attend a safety briefing and sign safe work permit for applicable work package(s).
• In addition to requiring standard Personal Protective Equipment for a construction work zone, the area around the grout pump is designated as requiring hearing protection.
• Uncured grout is highly alkaline. In the event that grout comes in contact with skin or clothing, you will be directed to nearest eye wash/safety shower for flushing.
• No areas on tour path requires sign in on a Radiological Work Permit (RWP) or wearing of rad dosimetry.
• Heat oasis station is available for cool off and hydration as required.
