SUMMARYOF INOPERABLE MONITORS
Monitor Dates of Inoperability Cause and Corrective Actions
1. Vent Noble Gas Monitor 6/19/92 to 7/29/92 Tho cord used to supply power fromthe pro-amplifier to tho amplifier wasmade from wire with an incorrectgauge causing loss of power to thepro-amp. This affected the FieldEffect Transistor causing becameinoperability. This is being tracked bya DER 2-92-2792.
Corrective Actions included:(1) 12-hour sampling analysis of grabsamples, and l2) replacement,recalibration, and restoration of thosystem's noble gas detector.
2. Stack GEMS 4/21/92 to 5/21/92 During a routine channel functionaltest, it was determined that tho 1ststage dilution pump flow controllerwas inoporablo. Since this dilution isrequired for high range monitoring,tho monitor was declared inoperable.
To comply with TechnicalSpocifications for gaseous offluonts,12-hour grab samples were analyzedfor noble gases and flow rate wasestimated every 4 hours. Iodine andparticulates were analyzed from a
cartridge on tho auxiliary samplingstation. The flow rate monitoringinstrument was repaired off sits. Amodification request to improveinstrument reliability has beensubmitted.

ATTACHNENT 2SOLID WASTE SOURCES
(Sheet 1 of 3)
1.0 RADWASTE FILTERS
1. 1 Mechanical radwaste filters filter resin and crud (backwash material)from the waste collector sub-system.
1.2 When a filter reaches a pre-determined differential pressure, the filterbackwashes the material into the backwash tank, which is then pumped tothe spent resin tank.
2. 0 RADWASTE DENINERALIZERS
2.1 The radwaste demineralizers are used as an ionic exchange media forprocessing high quality water from the waste collector tanks.
2,2 When determined the resin can NO longer be regenerated, the depletedresin is pumped to the spent resin tank.
3. 0 CONDENSATE DEMINERALIZER
3. 1 The condensate demineralizers remove soluble and insoluble impurities'from the condensate water to maintain reactor feedwater purity.
3.2 After it is determined these resins can NO longer be regenerated, thedepleted resins are pumped to the spent resin tank.
4.0 FLOOR DRAIN FILTER
4. 1 The floor drain filter contributes to solid waste because the filteruses diatomaceous earth to process liquid waste of low quality. Input tothe filter is from the floor drain system and the regeneration wastetank.
4.2 When the filter reaches a pre-determined pressure drop the filterbackwashes to the waste sludge tank for processing.
5.0 SPENT FUEL PHASE SEPARATOR
These tanks receive the exhausted powdered filter media (resins) fromthe fuel pool cleanup system which is subsequently pumped to the spentresin tank or directly to a liner in the Radwaste Truckbay forprocessing.

11.0 REGENERANT EVAPORATOR
11. 1 The regenerant waste evaporator receives regeneration solutions from thecondensate demineralizer system, the radwaste demineralizer resinregeneration system, and the radwaste regeneration sump. It can alsoprocess waste from the Floor Drain Collector System and the WasteDischarge Tanks.
11.2 The regenerant waste evaporator is designed to concentrate to a 25N byweight solid concentration of sodium sulfate.
11.3 The concentrates are then discharged to the evaporator bottoms tank fortransfer to the Radwaste Truckbay for vendor processing.
12.0 SPENT RESIN STORAGE TANK
12.1 Exhausted resin from the condensate demineralizer, the radwastedemineralizer, RWCU phase separator, the spent fuel pool phaseseparator, and the radwaste filter backwash tanks are sluiced to thespent resin storage tank.
12.2 The waste from the spent resin storage tank is pumped to the wastesludge tank for processing by the RDS 1000 in the Radwaste Truckbay.
13.0 ADVANCED LI UIO PROCESSING SYSTEM ALPS
13. 1 ALPS is a series of pressure vessels containing charcoal and resin usedto process low quality waste water from the floor drain collector systemand the regeneration waste tanks. If desired, waste from the wastedischarge tanks may also be processed by ALPS.
13.2 Exhausted resin and charcoal (from ALPS demineralizers and charcoalvessels) are sluiced to the filter sludge tank for storage or pumped tothe spent resin tank for storage.
13.3 Waste from the filter sludge tank is pumped to the Radwaste Truckbay forvendor processing using the RDS 1000
