ABWR D sign Documint . l q 2.9 Radioactive Waste Systems  !

V 2.9.1 Radwaste System Design Description The Radwaste (RW) System consists of a liquid waste system and a solid waste system. The liquid waste system includes primary containment penetrations, and inboard and outboard motor-operated isolation valves for the high conductivity and low conductivity waste drains from the lower drywell. The liquid waste system collects, treats, monitors, and either recycles or discharges radioactive liquid wastes within the plant. The solid waste system collects, sorts, monitors and either recycles or packages radioactive solid wastes within the plant.

The RW System is classified as non-safety-related with the exception of the primary containment isolation function.

The primary containment penetrations and isolation valves are classified as Seismic Category I, and ASME Code Class 2.

The inboard containment isolation valves are powered from Class 1E Division II, and the outboard isolation valve are powered from Class 1E Division I. In the RW p System, independence is provided is between Class 1E divisions, and between the j () Class 1E divisions and non-Class 1E equipment.

l l The main control room has control and open/close status indication for the ,

primary contamment isolation valves.

The safety-related electrical equipment that provides containment isolation and is located in the containment and Reactor Building is qualified for a harsh I environment. l The primary containment isolation motoroperated valves (MOVs) have active safety-related functions and perform these functions under differential pressure, .

fluid flow, and temperature conditions.

The liquid waste system has one discharge line which has a radiation monitor.

Discharge flow is terminated on receipt of a high radiation signal from this monitor.

V 2.14.1 Primary Containment System Design Description The Primay Containment System (PCS) encornpasses:

(1) A reinforced concrete containment stmcture with an internal steel liner. The structure includes various penetrations, equipment hatches and personnel access locks.

l (2) Structures inside the primay containment which partition the

! containment into dowell and wetwell regions, provide equipment support, radiation protection, and components for operation of the ABWR pressure suppression containment.

Figure 2.14.1 shows the basic configuration and scope.

The steel lined reinforced concrete containment structure attached to a l reinforced concrete basemat provides the primary containment pressure barrier i and is classified as ASME Code Section III, Division 2. The Reactor Pressure l Vessel (RPV) support pedestal and a diaphragm floor partition the containment volume into dowell and wetwell regions. The RPV support pedestal is a steel O' structure with concrete fill material. The diaphragm floor is a reinforced concrete structure. Other major internal structures within the containment are the reactor shield wall, lower dnwell personnel and equipment access tunnels l and the drywell equipment and piping support structure. These internal structures are steel fabrications.

l Penetrations through the containment pressure boundary include; the dnwell head closure, equipment hatches to both upper and lower dowell regions, l personnel locks into upper and lower dnwells, a combined personnel access and equipment hatch into the wetwell and piping and electrical penetrations. These pressure boundary appurtenances are steel structures classified as ASME Code l Section III, Division 1, Class MC.

l The containment design pressure is 3.16 kg/cm2 g.The design temperatures for the dnwell and the wetwell are 171 C and 104 'C respectively. The maximum calculated pressures and temperatures for the design basis accident are less than these design conditions. The primary containment pressure boundary including penetrations and isolation valves, has a leak rate equal to or less than 0.5% per day (excluding main steamline isolation valves (MSIV) leakage) of the containment gas mass at the maximum calculated containment pressure for the

,O V design basis accident.

6/18/93 -1 2.14 A

ABWR oesign occum:nt The reinforced concrete diaphragm floor separating the upper dnwell and the wetwell gas spaces, has a steel linear plate on the underside. The design differential pressure of the diaphragm floor between dnwell and wetwell is 1.76 kg/cm 2in the downward direction.

The RPV pedestal forms the lower dnwell region and consists of a cylindrical composite steel structure. It is anchored to'the basemat and supports the RPV ,

through a support ring girder.The pedestal also supports the reactor shield wall.

The pedestal consists of two concentric steel cylindersjoined together radially by vertical steel diaphragms and filled with concrete. The pressure suppression venting paths are an integral part of the pedestal structure. This includes: a) the ducts which interconnect the lower and upper drywell regions, b) the vertical downcomers from the interconnecting ducts to the horizontal vents, and c) the horizontal vents that direct steam into the suppression pool.

Vacuum relief between the dnwell volumes and the wetwell gas space is provided i l

by vacuum breaker valves on piping sleeves penetrating the pedestal wall. Eight normally closed swing check valves with nominal diameter of 500 mm are  ;

provided.

The water volume in the suppression pool including the vents is equal to or -  ;

greater than 3,580 m3 . The hori7ontal center line of the SRVDL quencher arms l are located at or below the elevation of the center row of horizontal vents in the suppression pool. 1 Water return paths connect the region within the pedestal to the vertical downcomers and horizontal vent paths. At least one meter of corium protection ,

fill concrete is provided on the lower drywell floor. Thermally activated flooding valves are also located in this region.

The following PCS components are classified as Seismic Categon I; the reinforced concrete containment structure, the dnwell head, equipment hatches to both upper and lower dowell regions, personnellocks into upper and l lower dnwells, the combined personnel access and equipment hatch into the wetwell, the basemat, the reactor pedestal, and containment isolation valves j together with their penetrations.
