xxi Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE Chapter 11 RADIOACTIVE WASTE MANAGEMENT The purpose of this chapter is to provide a complete description and state the design objectives of the radioactive waste systems to demonstrate compliance with the general provisions of 10 CFR Part 20 and 10 CFR Part 50. Performance evaluation of the radioactive waste treatment systems is described.
This chapter is divided into the following sections:
11.1 Source Terms 11.2 Liquid Radwaste System (LRS) 11.3 Gaseous Radwaste System (GRS) 11.4 Process and Effluent Radiological Monitoring System (RMS) 11.5 Solid Radwaste System (SRS) 11.6 Offsite Radiological Monitoring Program In the sections on liquid and gaseous radwaste systems, all significant release pathways of radioactive liquids and gases are identified and discussed, including those not directly associated with radwaste treatment systems; for example, blowdown system releases and steam leakage.
The principles and guidelines used in the design, construction, and operation of the radioactive waste management systems described in Chapter 11 are specified in the individual sections of Chapter 11 and in Table 11.0-1.
A pre-operation evaluation of the liquid and gaseous radwaste systems was performed to demonstrate the systems abilities to maintain releases within regulatory limits. To carry out an activity analysis of the plant that covers different combinations of basic operating parameters, two cases were selected:
(1) Design Basis Case - source term analysis used as input into the design of plant systems and topical areas (e.g., shielding and radwaste) to ensure compliance with 10 CFR Part 20. Inputs and assumptions were conservative.
(2) Normal Operation Case - source term analysis used for pre-operational evaluations to ensure compliance with the minimum equipment requirements of 10 CFR Part 50, Appendix I. Inputs and assumptions included anticipated operational occurrences and were more realistic than those for the design basis case.
These cases do not represent the typical results of actual plant operation, and the operational basis and resulting values for either case are not license limits. They were 11-1 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE developed for initial plant licensing and are not expected to be updated, therefore they are considered historical.
HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
For the Design Basis Case, the plant was assumed to have been operated for a full year at full thermal power of 3568 MWt with a capacity factor of 80 percent and a fuel defect level of 1 percent. The radwaste systems were assumed to be in operation as designed, and primary system leakage was assumed to be negligible. The complete set of other assumptions associated with this case are listed in Table 11.1-2 and discussed in detail in the following sections.
For the Normal Operation Case the plant was assumed to have been operated for a full year at full power with a capacity factor of 80 percent and a fuel defect level of 0.12 percent. Coincident with this condition, it was assumed that there existed primary system leakage of 100 pounds per day to the secondary system, 1 percent of primary coolant noble gas inventory and 0.001 percent of primary coolant iodine inventory to the containment, and 160 pounds per day to the auxiliary building. These assumptions are in agreement with those provided in NUREG-0017, April 1976 for normal operation of a pressurized water reactor (PWR) (refer to Reference 9 of Section 11.1). The complete set of assumptions for this case is also discussed in the following sections. As a result of the analyses of these cases, the following conclusions can be drawn.
Diablo Canyon Power Plant (DCPP) Unit 1 and Unit 2 can be operated under normal conditions, including the consideration of anticipated operational occurrences, in conformance with:
(1) The general provisions of 10 CFR Part 20 and 10 CFR Part 50 (2) The annual dose limits established in 10 CFR Part 20 for the release of radioactive materials (3) The annual radiation dose limits specified in 10 CFR Part 50, Appendix I.
The radioactive waste release values provided in this chapter are nominal values.
Actual release values are reported to the NRC in the DCPP Annual Radioactive Effluent Release Report.
11-2 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE 11.1 SOURCE TERMS This section describes the routine (or operational) source term and the pre-operational evaluation of source term for the Design Basis Case and the Normal Operation Case.
Routine Source Term:
Primary coolant concentrations, leakage rates, and effluent release rates based on the routine source term are used for evaluation of the LRS and GRS to determine whether these systems meet the dose design objectives of 10 CFR Part 50 Appendix I.
The operational source term in the reactor coolant system (RCS) and supporting systems are monitored on a routine basis in accordance with plant Technical Specifications and plant-approved procedures. The information is readily available to site personnel for evaluating source term and trends.
The station policy is to operate the plant with zero fuel defects to achieve a low source term in the primary coolant.
The plant operating philosophy is to maintain leakage from the primary system well below Technical Specification limits.
This operating philosophy is fundamental to minimizing the input of radioactive material into the LRS and the GRS, and thereby minimizes activity that may be released from the station.
There have been periods when a fuel leak develops and the RCS Dose Equivalent I-131 specific activity (DEI) has been near the Technical Specification value of 1.0 Ci/gm for periods of time. The station has demonstrated that the LRS and GRS operating per station procedures have maintained plant releases at a fraction of Technical Specification and 10 CFR Part 20 limits.
Routine operating RCS DEI is normally only a fraction of the Technical Specification value of 1.0 Ci/gm.
The routine operating source term is much lower than the cases described below.
Tritium is produced as part of the fission process of the reactor and its production is a direct function of power produced and capacity factor. Tritiated water is not removed in the treatment systems. Given that tritium has a 12.3 year half-life, essentially all the tritium produced is released from the plant via the LRS or through evaporation via the plant vent.
HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
Pre Operation Source Term Evaluations:
11.1-1 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE The pre-operational evaluation of radioactive materials produced and stored in the reactor system is reported and discussed in this section. These sources have been computed for two basic sets of plant operating conditions: the Design Basis Case and the Normal Operation Case.
The complete isotopic source terms are presented in tabular form along with the basic assumptions used in the computations. The activities and concentrations were calculated with the EMERALD-NORMAL (Reference 8) digital computer program. A detailed discussion of the physical data and assumptions used is contained in the following paragraphs:
11.1.1 BASIC PHYSICAL DATA AND CONSTANTS The values of isotopic physical data used in the radiological effects analyses are listed in Table 11.1-1. The values of half-lives and fission yields were taken from the Meek and Rider report (Reference 1) and from Tobias (Reference 10) and are in general agreement with those in TID-14844 (Reference 2) and ORNL-2127 (Reference 3). The values for average beta energies are those provided in Perkins and King (Reference 4) and the average gamma energies are taken from Tobias. The values of decay constants were calculated from the half-lives with the standard formula. The fission yields were modified to account for plutonium buildup by using the values for uranium and plutonium fissioned during an equilibrium core cycle as follows:
Yield (U + Pu) = [Fissions (U) x Yield (U)] + [Fissions (Pu) x Yield (Pu)]
Fissions (U + Pu)
The number of fissions per megawatt-second is taken to be 3.15 x 1016, which agrees well with the value of 3.2 x 1016 used in Reference 2.
11.1.2 DETERMINATION OF ACTIVITY INVENTORIES IN REACTOR CORE HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
The EMERALD-NORMAL program was run for 11 months with zero initial activities, and the result was decayed one month. The resulting core activities (assuming one-third of the core was replaced at refueling) were then set equal to the initial activities and the process repeated. Taking one-third of the activities after the first cycle, plus one-third of the activities after the second cycle, gives an approximation to the initial activities for an equilibrium core cycle. The core inventories for the year's operating cycle were then computed using an 80 percent capacity factor to ensure a realistic inventory of Kr-85.
The power level and other basic assumptions are provided in Tables 11.1-2 and 11.1-3.
The resulting core inventories are listed in Tables 11.1-4 and 11.1-5. These calculated core inventories are in general agreement with those tabulated in TID-14844, with those listed in the Reactor Safety Study (WASH-1400) (Reference 12), and with those listed in the DCPP Preliminary Safety Analysis Report (Reference 5).
11.1-2 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE The actual maximum operating configuration is 21 months of operation, with a mixture of fuel with enrichments up to 5 percent, and with a maximum burnup of 50,000 MWD/MTU. The updated equilibrium isotopic core inventory of dose significant isotopes is presented in Table 15.5-77. A summary of key assumptions and a description of the method used to determine the updated core inventory is provided in Table 11.1-2A and Section 15.5.3.1, respectively.
HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
11.1.3 DETERMINATION OF INVENTORIES IN FUEL ROD GAPS The computed gap activities are based on buildup in the fuel from the fission process and diffusion to the fuel rod gap at rates dependent on the operating temperature. For this analysis, the fuel pellets were divided into five concentric rings, each with a release rate dependent on the mean fuel temperature within that ring. The diffusing isotope is assumed present in the gas gap when it has diffused to the boundary of the outer ring.
The core temperature distribution used in this analysis, based on hot channel factors of FH = 1.70 and Fq = 2.82, is presented in Table 11.1-6.
The diffusion coefficient, D', for Xe and Kr in UO2, varies with temperature in accordance with the following expression:
E 1 1
( )
D'T D' (1673) exp R T 1673 (11.1-1) where:
E = activation energy D' (1673 ) = diffusion coefficient at 1673 K = 1 x 10-11 sec-1 T = temperature in K R = gas constant This expression is valid for temperatures above 1100°C. Below this temperature, fission gas release occurs mainly by two temperature-independent phenomena, recoil and knock-out, and is predicted by using D' at 100°C. The value used for D' (1673 K),
based on data at burnups greater than 1019 fission/cc, is used to account for possible fission gas release by other mechanisms and pellet cracking during irradiation.
The diffusion coefficients for iodine isotopes are assumed to be the same as those for Xe and Kr (References 6 and 7).
The resulting fractions of core activity present in the fuel rod gaps are listed in Table 11.1-7, along with the total inventories of activity in the gaps.
11.1-3 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE As part of the implementation of Alternative Source Terms to assess post-accident dose consequences to the public as well as habitability of the control room and technical support center, the isotopic inventories in fuel rod gaps have been updated as discussed in Section 15.5.3.3. The isotopic activity in the gap assumed for the Locked Rotor Accident and the Control Rod Ejection Accident are provided in Table 15.5-80.
The isotopic activity in the gap assumed for the Fuel Handling Accident is presented in Table 15.5-47C.
11.1.4 DETERMINATION OF PRIMARY COOLANT ACTIVITIES The basic data and assumptions used in calculating the coolant concentrations for the Design Basis Case and the Normal Operation Case are provided in Tables 11.1-2, 11.1-3, 11.1-8, 11.1-9, and 11.1-10. The coolant concentrations and activities, listed in Tables 11.1-11, 11.1-12, and 11.1-13, are provided for the operating temperature. The activities of corrosion products deposited in the steam generator are provided in Table 11.1-14. The total amounts of activity produced and removed from the coolant during the operating period are provided in Tables 11.1-16 and 11.1-17. All models and equations, including parent-daughter production, purification terms, boron feed-bleed terms, and coolant leakage terms, are provided in detail in Reference 8, and are generally consistent with those provided in NUREG-0017, April 1976 (Reference 9).
The demineralizer decontamination factors assumed are listed in Table 11.1-15. The basic assumptions and data used in calculating the activities in the pressurizer are listed in Table 11.1-18, and the calculated activities for the two cases are provided in Tables 11.1-19 and 11.1-20.
The method used to develop the reactor coolant concentration associated with the updated equilibrium isotopic core inventory discussed in Section 11.1.2 is summarized in Section 15.5.3.2. The updated coolant concentrations with 1 percent fuel defects is presented in Table 11.1-11A. A summary of key assumptions used in developing the coolant concentrations is provided in Table 11.1-2A.
11.1.5 DETERMINATION OF TRITIUM ACTIVITIES IN PRIMARY COOLANT Tritium atoms are generated in the fuel at a rate of approximately 8 x 10-5 atoms per fission, or 1.05 x 10-2 curies/MWt/day. Any boron-bearing control rods in the core are a potential source of tritium.
A direct source of tritium is the reaction of neutrons with dissolved boron in the reactor coolant. Boron is used in the reactor coolant for reactivity control. Neutron reactions with lithium are also a direct source of tritium. Lithium hydroxide is used for pH control.
Figure 11.1-1 shows calculated versus measured tritium production in the reactor coolant for the R. E. Ginna plant. A 10 percent release from the fuel rods was assumed for the calculation.
11.1-4 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE 11.1.5.1 Ternary Fissions - Cladding Diffusion With zirconium alloy cladding, approximately 10 percent of the tritium produced in the fuel will diffuse through the cladding into the coolant (Reference 11).
11.1.5.2 Tritium Produced from Boron Reactions The neutron reactions with boron that result in the production of tritium are:
B10 (n, 2 ) T B10 (n, ) Li7 (n, n ) T B11 (n, T) Be9 B10 (n, d) Be9* (n, ) Li6 (n, )T Of the above reactions, only the first two contribute significantly to the tritium production.
The B11 (n, T) Be9 reaction has a threshold of 14 MeV and a cross section of 5 mb.
Since the neutrons produced at this energy result in a flux of less than 109 n/cm2-sec, the tritium produced from this reaction is negligible. The B10 (n,d) reaction may be neglected since Be9* has been found to be unstable.
11.1.5.3 Tritium Produced from Lithium Reactions The neutron reactions with lithium resulting in the production of tritium are:
Li7 (n, n ) T Li6 (n, ) T Lithium hydroxide is used for pH adjustment of the reactor coolant. Lithium concentrations may reach a value of 6.0 ppm at the beginning-of-cycle. During normal plant operations the lithium is maintained within an operational band per plant procedure. At the end-of-cycle, the lithium concentrations may decrease to 0.0 ppm.
This is accomplished by the addition of Li7 OH and by a cation demineralizer included in the chemical and volume control system. This demineralizer will remove any excess of lithium such as could be produced in the B10 (n, ) Li7 reaction.
The Li6 (n,) T reaction is controlled by limiting the Li6 impurity in the Li7 OH used in the reactor coolant and by lithiating the demineralizers with 99.9 atom percent Li7.
11.1.5.4 Control Rod Sources In a fixed burnable poison rod, there are two primary sources of tritium generation: the B10 (n, 2 ) T and the B10 (n, ) Li7 (n, n ) T reactions. Unlike the coolant, where the Li7 level is controlled, there is a buildup of Li7 in the burnable poison rods. The burnable poison rods are required during the first year of operation only. During this time, the tritium production is 72 curies/pound B10.
11.1-5 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE The control rod materials used at DCPP are Ag-In-Cd; there are no tritium sources in these materials.
11.1.5.5 Tritium Production from Deuterium Reactions Since the fraction of naturally occurring deuterium in water is less than 0.0015, the tritium produced from this reaction is negligible (less than 1 curie per year).
11.1.5.6 Total Tritium Sources in Coolant A summary of the sources of tritium in the RCS are listed in Table 11.1-22, and all basic data and assumptions used are provided in Table 11.1-21. The calculated total tritium produced in the reactor plant, 1640 curies/year, agrees fairly well with the NUREG-0017, April 1976 value of 0.4 Ci/MWt/year, which gives 1427 curies/year, the difference being conservative.
11.1.6 DETERMINATION OF SECONDARY SYSTEM ACTIVITIES In order to estimate the potential plant releases as a result of secondary system leakage or discharges, during periods when significant activity exists in the steam system, the steam system activity levels have been determined. As discussed earlier, the range of possible combinations of plant operating conditions has been represented by making an activity analysis on the basis of 0.12 percent fuel defects, coincident with a leakage of 100 pounds per day to the secondary system. The projected plant releases for this condition are based on the assumption that these conditions persist throughout the full year. The steam system operating conditions assumed for the activity analysis are listed in Tables 11.1-23, 11.1-24, and 11.1-25, and the results of the analysis are provided in Tables 11.1-26 through 11.1-31. The equations and models for the activity balances and transport calculations are detailed in Reference 8, and they are generally consistent with those provided in NUREG-0017, April 1976.

11.2.2 SYSTEM DESCRIPTION 11.2.2.1 General DCPP Unit 1 and Unit 2 share a common LRS, except for equipment located inside containment. A detailed piping and instrumentation schematic of the LRS is shown in Figure 3.2-19. The common LRS consists of the following five collection subsystems:
(1) Equipment drain subsystem (refer to Section 9.3.3)
(2) Floor drain subsystem (refer to Section 9.3.3)
(3) Chemical drain subsystem (refer to Section 11.2.2.1.3)
(4) Laundry and hot shower and laundry/distillate subsystem (refer to Section 11.2.2.1.4)
(5) Demineralizer regenerant subsystem (refer to Section 11.2.2.1.5)
These five collection subsystems are described in the following sections.
The floor drain, chemical drain, laundry/distillate, laundry and hot shower, and demineralizer regenerant subsystems generally collect low activity liquid radwastes.
The equipment drain subsystem collects liquids with variable activity levels. The demineralizer regenerant subsystem is used as backup for the floor drain and equipment drain subsystems.
Following treatment, effluents from the LRS are released to the environment at the discharge structure via either units auxiliary saltwater (ASW) system (refer to Figure 11.2-9). The LRS releases are diluted in the ASW system and main circulating 11.2-5 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE water system flows. Releases require positive operator action, are continuously monitored, and are automatically isolated in the event of a high radiation alarm or a power failure.
A major source of liquid radwaste is the RCS. The bulk of these wastes are processed and retained within the CVCS, with a portion being routed to the LRS. A piping and instrumentation schematic of the CVCS is shown in Figure 3.2-8. A complete description of the CVCS is included in Section 9.3.4.
11.2.2.1.1 Equipment Drain or Closed Drain Subsystem Closed drainage from equipment in the containment building flows to the RCDT as described in Section 9.3.3.2.1.1.
When the RCDT reaches a preset liquid level, the wastes are automatically pumped to the liquid holdup tanks (LHUTs)for processing in the CVCS. The pumps may also be manually started prior to reaching the preset level. The wastes may also be pumped to the equipment drain receiver tanks or the refueling water storage tanks (RWSTs) when required. An integrating flow meter on the reactor coolant drain pump discharge reads out on the auxiliary building control board digital system, and RCDT high and low level alarms to the main annunciator are provided.
Closed drainage from equipment in the auxiliary building is collected in the MEDT as described in Section 9.3.3.2.1.2.
When the MEDT reaches a preset liquid level, the wastes are automatically pumped to the equipment drain receiver tanks. A high level alarm function is provided.
Closed drain wastes being transferred to the equipment drain receiver tanks are routed to one of the two tanks. When that tank reaches its high level setpoint, incoming flow is automatically diverted to the second equipment drain receiver tank. The filled tanks are normally recirculated, sampled, and analyzed before further batch processing. A high and low level alarm function is provided for each tank.
11.2.2.1.2 Floor Drains and Open Drain Subsystem Inside containment floor drain wastes are collected in the containment sumps and the reactor cavity sump as described in Section 9.3.3.2.2.1.
Integrating flow meters in the discharge lines from the reactor cavity sumps and containment sumps are provided to detect leakage from in-containment sources.
Potentially contaminated auxiliary building floor drain wastes are collected in the auxiliary building sump as described in Section 9.3.3.2.2.2.
11.2-6 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE The RHR compartments spills collect in the RHR sumps that are normally discharged to the floor drain receivers.
When a sump has filled to a preset level, the radwastes are automatically pumped to one of two floor drain receiver tanks. When a tank has reached its high level setpoint, sump flow will automatically be diverted to the second floor drain receiver tank. The filled tank is normally recirculated, sampled, and analyzed before further batch processing. A high level alarm function is provided for each sump. A high level and low level alarm function is provided for each floor drain receiver tank.
11.2.2.1.3 Chemical Drain Subsystem Chemical wastes are generated due to routine chemical and radiochemical sampling and analyses. Chemical wastes from both units drain by gravity to a divided chemical drain tank. The filled section is recirculated, sampled, and analyzed before discharge.
11.2.2.1.4 Laundry and Hot Shower, and Laundry/Distillate Subsystem Laundry, hot shower, and treated CVCS liquids are generally very low in activity. The laundry and hot shower wastes are generated by laundering contaminated protective clothing and by personnel decontamination. CVCS LHUT water is routed to the LRS when reuse in the reactor cavity or spent fuel pool is not possible.
The hot shower wastes flow by gravity to one of the laundry and hot shower tanks.
When one of the laundry and hot shower tanks is filled, the flow is manually diverted to the second tank. The filled tank is recirculated, sampled, and analyzed before further batch processing or discharge.
The laundry waste will normally drain to one of the laundry/distillate tanks for discharge.
Treated LHUT water may be drained to one of the laundry/distillate tanks or to one of the demineralizer regenerant receiver tanks for further treatment by the LRS. When one of the laundry/distillate tanks is filled, the flow is manually diverted to the second tank. The filled tank is recirculated, sampled, and analyzed before further batch processing or discharge.
11.2.2.1.5 Demineralizer Regenerant Subsystem The demineralizer regenerant subsystem consists of two 15,000 gallon demineralizer regenerant receivers (arranged in parallel) located adjacent to the equipment drain receivers in the auxiliary building. Originally, it was intended that regeneration wastes from the steam generator blowdown (SGBD) treatment system, deborating demineralizers, or evaporator distillate demineralizers were to be routed to these tanks, and neutralized by concentrated sulfuric acid or sodium hydroxide. The SGBD regeneration system never operated and changes in California environmental regulations halted neutralization of other regenerants in the demineralizer regenerant receivers.
11.2-7 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE The demineralizer regenerant receivers collect equipment or floor drain liquid and function as surge capacity for these subsystems. In addition, treated LHUT liquid can be drained to the demineralizer regenerant receivers for additional processing.
11.2.2.2 Liquid Radwaste System Operation The LRS is operated on a batch basis. When a floor drain receiver, equipment drain receiver, chemical drain, laundry/distillate tank, laundry and hot shower tank, or demineralizer regenerant receiver is filled, it is isolated to prevent accumulation of additional contaminated waste. Control interlocks prevent tanks from being simultaneously filled and discharged. The tanks are normally recirculated, sampled, and analyzed to determine whether additional treatment is required. Batches of equipment and floor drains are normally processed to reduce radioactivity concentrations prior to discharge.
11.2.2.2.1 Liquid Radwaste Processing Sub System Batches that require further treatment are processed through the radwaste media filters, ion exchangers, filters, and/or mobile liquid process systems. The radwaste media filters and ion exchangers are normally operated in series. Mobile liquid process systems may be used to augment LRS in-plant components. The mobile liquid process systems meet the requirements of the associated LRS in-plant components. Treated liquid is collected in the processed waste receivers. In addition, treated LHUT liquid can be routed to the processed waste receivers. These batches are then sampled and analyzed prior to discharge.
11.2.2.2.2 Liquid Radwaste Discharge Sub System Batches that contain sufficiently low quantities of radioactivity to meet discharge limits are treated by filtration and discharged to the outfall of the circulating water system via the ASW discharge. Circulating water flow is verified prior to initiating a release.
Written operating procedures govern the mechanics of discharging liquid radwaste to the unrestricted area (Reference 8).
As part of the procedures, records of plant water inventories, circulating water flow rates, and radwaste batch analysis data sheets are kept to ensure that the discharges are maintained below the applicable regulatory limits.
11.2.2.3 System Design The components of the LRS are listed in Table 11.2-10. A similar listing for the CVCS is provided in Table 9.3-6. Included are equipment size or capacity, applicable flowrate, material of construction, and design temperature and pressure.
11.2-8 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE Applicable codes and standards for process equipment used in the LRS are presented in Table 3.2-3. Equivalent data for the CVCS are shown in Table 9.3-5.
The seismic and quality group classifications for these components and associated piping are also described in Section 3.2.2. Radiological monitoring is discussed in detail in Section 11.4.
The routing of LRS piping is strictly controlled by the design engineers and is specified on the piping drawings. Consequently, there are field-fabricated lines, but no field-routed lines. Lines that are field-fabricated have the following characteristics:
(1) the lines are routed to minimize operator dose, all deviations from the specified routing require prior approval of the piping engineer, and as-built drawings are made showing final dimensions, (2) the sizes, schedules, materials, and code classes are specified on the piping drawings, (3) the field-fabricated piping is similar to shop-fabricated piping in design, quality assurance procedures, and inspection, (4) pipe hanger placement is not specified on piping drawings, but a maximum spacing between hangers is specified as a design standard, and (5) a design review is conducted in accordance with the quality assurance procedures described in the Diablo Canyon Quality Assurance Program Description in the same manner as for shop-fabricated piping.
11.2.2.4 Performance Data LRS process equipment is evaluated for its effectiveness in removing radioactivity on a batch basis. Approved plant procedures govern concentrations of activity that must be processed and limits the activity in any individual batch prior to release. When the process equipment removal efficiency no longer produces water to meet these requirements, the filters, media, or ion exchange resin is replaced.
11.2.2.5 Plant Releases 11.2.2.5.1 Current Operational Releases Refer to Section 11.2.3.13.1 for a discussion of current operational releases from the LRS.
11.2-9 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
11.2.2.5.2 Pre-Operational Estimated Release Evaluation The following information provides historical perspective demonstrating that DCPP's anticipated operation would result in releases within applicable regulatory limits. This information does not necessarily reflect current operating conditions or practices.
The estimated releases based on the original design were calculated with the EMERALD-NORMAL computer program, supplemented by hand calculations. Two process flow diagrams of the LRS are presented to depict the modes of operation for the two cases used for radiation release analysis: the Design Basis Case, and the Normal Operation Case. The flow diagram for the Design Base Case (refer to Figure 11.2-2) shows the waste stream sources and processing route of liquid radwaste for the assumptions of this case. The numbered waste input streams have their annual flow and isotopic spectra listed in Table 11.2-5. The numbered process streams are listed in Table 11.2-8, along with flows and isotopic concentrations. The flow diagram for the Normal Operation Case is shown in Figure 11.2-3. Flows and isotopic parameters for this case are listed in Tables 11.2-5 and 11.2-9.
The detailed assumptions used in calculation of estimated activity release from the LRS are listed in Table 11.2-1. Tables 11.2-3 and 11.2-4 list the activity concentration spectrum for the input sources. A tabulation of the estimated annual release by isotope is provided in Tables 11.2-14 and 11.2-15 for the two cases.
For the Normal Operation Case with anticipated operational occurrences, as defined in Regulatory Guide 1.112, April 1976 (Reference 7), an additional release of 0.15 Ci/yr per reactor with the same isotopic makeup as in Table 11.2-15 was assumed. This annual release is provided in Table 11.2-18 for one unit. Since an average of 2 days holdup time is available upstream of both the boric acid and waste treatment systems, no additional release, assuming the systems are out of service, was postulated.
The detailed assumptions used in the calculation of estimated activity release from the CVCS to the LRS are listed in Table 11.2-2. A tabulation of the isotopic flows through the system components is provided in Tables 11.2-6 and 11.2-7, and the estimated annual releases to the LRS are provided in Tables 11.2-8 and 11.2-9 for the Design Basis and Normal Operation Cases.
For purposes of estimating annual average plant radionuclide releases, approximately two-thirds of the boric acid evaporator distillate produced was assumed to be recycled to the primary water storage tank, and the rest routed to the LRS. This release (350,000 gallons/year for each unit) is primarily for tritium control purposes.
A list of assumed decay times for system tanks is provided in Table 11.2-13.
Demineralizer DFs are listed in Table 11.1-15.
11.2-10 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE During conditions corresponding to the Design Basis Case, which assumes a 1 percent fuel defect level with negligible primary system leakage, the floor drain wastes will have an approximate activity level of 0.0015 mCi/cc. These wastes are normally filtered and released to the main condenser circulating water discharge tunnel.
During conditions corresponding to the Normal Operation Case, which assumes a 0.12 percent fuel defect level with primary system leakage, the activity level of the floor drain wastes is approximately 0.1 mCi/cc. Under this operating condition, the wastes would be processed through the filters and/or ion exchangers.
The chemical drain wastes would have an approximate activity level of 9 x 10-4 Ci/cc during conditions corresponding to the Design Basis Case. During conditions corresponding to the Normal Operation Case, the wastes would be approximately 1 x 10-4 Ci/cc.
During conditions corresponding to the assumptions of Design Basis Case, the approximate activity level in the processed effluent from the equipment drain receiver tanks would be 0.007 Ci/cc. The activity level of the processed effluent would be 0.002 Ci/cc during conditions corresponding to the Normal Operation Case.
The SGBD system is depicted on two process flow diagrams that show the two paths of operation of the system and the assumptions used in the radiation release analyses.
Figure 11.2-4 shows the discharge path with blowdown directed to the blowdown tank and the circulating water discharge structure. Figure 11.2-5 shows the recycle path with blowdown directed to the blowdown treatment system. For the Design Basis Case, it was assumed that the blowdown is processed via the discharge path because this case assumes no primary-to-secondary leakage and no activity is present in the secondary system. For the Normal Operation Case, it was assumed that the blowdown is processed only via the recycle path and the discharge path is isolated since the assumptions for this case result in significant levels of activity in the secondary system.
Table 11.2-16 shows the total annual volumetric flows for one unit and the activity concentrations corresponding to the alphabetically labeled process streams in these two figures for the Normal Operation Case.
The estimated annual activity releases from the turbine building sump for one unit are listed in Tables 11.2-14 and 11.2-15 for the Design Basis Case and the Normal Operation Case, respectively. Table 11.2-17 lists the total annual estimated volumes released from the LRS for two units for both cases and includes the turbine building sump discharge.
The tritium concentration in the RCS is controlled by bleeding coolant from the RCS to the LRS via the CVCS (refer to Section 9.3.4). Other losses from the RCS are through radioactive decay and mixing of the primary coolant with refueling cavity water during refueling. The calculation of the tritium concentration in the various plant water sources was based on the following assumptions:
11.2-11 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE (1) Tritium activity in the RCS is provided in Table 11.1-22 for the anticipated operational occurrences case.
(2) The total volume of water released from the RCS for the analysis of the Design Basis Case and the anticipated operational occurrences case is 350,000 gallons per year per unit.
(3) The temperature of the spent fuel pool is constant at 100°F throughout the life of the plant except during refueling when the temperature rises to 125°F. The air above the spent fuel pool is 80°F at 70 percent relative humidity.
(4) The water temperature of the refueling tunnel, when filled with borated water from the RWST, is 125°F. The air above the refueling tunnel is 80°F at 70 percent relative humidity. Mixing with 15 percent of the water from the spent fuel pool occurs during each refueling period.
(5) During refueling, the containment purge fans are in continuous operation.
(6) No water is lost from the spent fuel pool or RWST, except through evaporation.
(7) Evaporation from the spent fuel pool is calculated by the equation (Reference 3):
V 95.0 + 0.425 Va
= ( pw pa ) (11.2-1)
A W where:
V = loss rate from the water volume, lbm/hr A = exposed area of the water volume, ft2 W = latent heat of vaporization of the water, Btu/lbm Va = velocity of the air across the surface of the water, ft/min pw = vapor pressure of the water, in. of Hg pa = vapor pressure of the water in air, in. of Hg The important parameters for evaluating tritium losses and distribution in the plant are provided in Table 11.2-11.
The resulting tritium concentrations in various plant areas are shown in Figures 11.2-6 through 11.2-8. It should be noted that the tritium concentrations plotted in these figures are yearly averages or, in the case of airborne concentrations during refueling, are averages during the refueling periods, based on a 1 year fuel cycle with 11 months operation and 1 month refueling. The tritium management procedures are designed to ensure that tritium airborne concentrations in all normally occupied plant areas are 11.2-12 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE significantly below levels required to ensure compliance with 10 CFR Part 20, Subparts C and D. The restriction of primary coolant tritium concentration by releasing demineralized water from the RCS is intended to reduce in-plant personnel radiation dose.
The above analysis was performed to demonstrate that DCPP normal operation radiological effluents meet the criteria of 10 CFR Part 50, Appendix I. This analysis is conservative and bounds DCPP current operation. The analysis was performed prior to plant operation and will be modified only if a design change or operational change rendered it non-conservative.
11.2.2.6 Dilution Factors 11.2.2.6.1 Current Operational Doses The main condenser cooling water and the ASW system of Unit 1 and Unit 2 are used for dilution of released liquid radwastes. The dilution flow available per unit is 862,000 gallons per minute. Refer to Section 10.4.5 for a description of the circulating water system and Section 9.2.7 for a description of the ASW system.
HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
11.2.2.6.2 Pre-Operational Dose Factors The pre-operational estimated activity concentrations listed in Tables 11.2-21 through 11.2-23 are for one unit's turbine building wastes and LRS diluted with one unit's annual circulating water flow. It should be noted that this method of calculation yields a maximum annual average concentration within the circulating water discharge structure.
For the calculation of all internal and external doses from liquid effluent releases, a dilution factor of 5 was used from the point of release to the organism or dose point.
This value was taken from Table A-1 of Regulatory Guide 1.109, March 1976 (Reference 5) as a conservative estimate of the dilution at the edge of the initial mixing zone for a high-velocity surface discharge. This factor is considered very conservative; experimental dye studies (Reference 2) have determined that the average dilution factor for fish, invertebrate, and sediment exposure to liquid effluents is 100. The dilution factor of 5 was confirmed by the NRC staff in the Final Environmental Statement for DCPP Unit 1 and Unit 2 (Reference 4).
11.2.2.7 Calculated Doses 11.2.2.7.1 Current Operation Doses Refer to Sections 11.2.3.15, 11.2.3.19, and 11.2.3.20 for discussions of current operational doses from the LRS.

DCPP UNITS 1 & 2 FSAR UPDATE HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
11.2.2.7.2 Pre-Operation Estimated Doses Pre-operational radiation dose calculations are presented in Tables 11.2-24 through 11.2-26 for the Design Basis Case, the Normal Operation Case, and the Normal Operation Case with anticipated operational occurrences, respectively. These tables list the doses from one unit. The dose via water pathways was calculated with the EMERALD-NORMAL program, which uses liquid dose models and assumptions based on Regulatory Guide 1.109, March 1976.
Pre-operational calculations included direct exposures through contact with water by swimming or by exposures in shoreline areas where minute quantities of radioactivity may be deposited.
The usage factor for fish and invertebrate consumption and sediment exposure time were taken from Regulatory Guide 1.109, March 1976, as were the bioaccumulation factors for fish, invertebrates, and plants. The complete set of bioaccumulation factors used is listed in Table 11.2-20. A list of effluent concentrations after dilution is provided in Tables 11.2-21 through 11.2-23.
The individual doses from fish consumption were based on rockfish caught and eaten by a sport fisherman, with a one day delay between the time of catch and consumption.
The individual doses from invertebrate consumption were based on abalone, caught non-commercially and eaten with a one day delay between the time of catch and consumption. The possible doses from swimming or boating were based on the exposure periods listed in Regulatory Guide 1.109, March 1976. A summary of the dose assumptions for liquid pathways exposures is provided in Table 11.2-19.
On the basis of the calculated estimates of radiation dose presented in Tables 11.2-24 through 11.2-26, it was concluded that under normal conditions, including the consideration of anticipated operational occurrences, the potential dose from liquid effluents from DCPP Unit 1 and Unit 2 would be well within the dose limits specified in 10 CFR Part 50, Appendix I.

DCPP UNITS 1 & 2 FSAR UPDATE The liquid radwaste effluent monitor (R-18) continuously monitors discharges from the LRS. A high-radiation signal initiates automatic valve closure and flow is diverted to the equipment drain receiver tanks.
The SGBD sample monitor (R-19) monitors the liquid phase of the secondary side of the SG for radioactivity. A high-radiation signal causes the isolation valves in the blowdown and sample lines, acting with the valve in the line from the blowdown tank to the discharge structure, to close and the blowdown tank liquid effluent to be diverted to the equipment drain receiver tank.
The SGBD tank liquid effluent monitor (R-23) continuously measures liquid effluent from the SGBD tank. A high-radiation signal isolates the blowdown discharge, and diverts blowdown tank liquid effluent to the equipment drain receiver tank.

11.2-17 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.2.3.11 General Design Criterion 68, 1967 - Fuel and Waste Storage Radiation Shielding Radiation shielding in the auxiliary building protects personnel working near waste storage facilities from doses in excess of 10 CFR Part 20 limits (refer to Section 12.1.7.3).
11.2.3.12 General Design Criterion 69, 1967 - Protection Against Radioactivity Release from Spent Fuel and Waste Storage The PG&E Design Class I LRS CIVs are designed to ensure that the containment atmosphere will be isolated in the event of a release of radioactive material inside containment. The isolation time limits specified ensure that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses of a LOCA (refer to Section 6.2.4).
In accordance with UFSAR Section 3.2.2.1.2, fluid systems and fluid system components that contain or may contain radioactive material, but whose failure would not result in calculated potential exposures in excess of 0.5 rem whole body (or its equivalent to parts of the body) at the site boundary, may be classified as PG&E Design Class II.
As part of the acceptability of tanks that contain liquid waste that have a PG&E Design Class II classification, an evaluation was performed of the dose consequences at the site boundary of a Liquid Holdup Tank (LHUT) failure accident.
Radioactive liquid waste holdup tanks are used as part of the chemical and volume control system (CVCS) to collect and permit decay of radioactive liquids drawn from the reactor primary coolant for reactivity control. The CVCS is described in detail in Section 9.3.4.
Five liquid holdup tanks are provided for the two units to afford operating flexibility and allow one or more tanks to be isolated from the rest of the system for extended periods of time. The liquid processed through the holdup tanks contains dissolved fission and activation products, as well as radioactive noble gases mixed with nitrogen cover gas used in the tanks.
The liquid holdup tanks are located in vaults which are Design Class I structures, so that in the event of a rupture or spill all liquids are retained in the vaults. The volume of holdup tank vaults is sufficient to contain the full contents of the holdup tank without spillage from the vaults. Any gases released from the liquid holdup tanks are collected by the auxiliary building ventilation system and discharged via the auxiliary building vent.
11.2-18 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE In the evaluation of the liquid waste holdup tank rupture accident, the following fission product accumulation and release assumptions are used for the design basis case.
(1) The reactor has been operating at full power with 1 percent defective fuel for an equilibrium core cycle.
(2) A liquid holdup tank has been filled with primary coolant at a rate of 132 gpm, with credit for decay as the tank is filling.
(3) The failure occurs immediately upon completion of the liquid transfer, releasing the entire contents of the tank to the LHUT vault. The assumption of the release of the contents of only a single tank is based on a design that allows all liquid holdup tanks to be isolated from each other when they are in use.
(4) All of the noble gases and varying amounts of the iodines are released, unfiltered, from the LHUT vault to the environment, via the plant vent. The release is treated as a ground level release.
(5) All of the noble gases are exhausted to the environment over a 2-hour time period, or at the rate of the LHUT ventilation exhaust flow, whichever results in a more rapid release rate.
(6) The iodine concentration in the LHUT vault air space and ventilation exhaust flow is based on an equilibrium iodine distribution balance between the spilled LHUT liquid and the air, and is dependent on the temperature, pH, and concentration of iodine in the spilled fluid. The iodines are released to the environment as they evolve out of the spilled liquid at the rate of the LHUT vault ventilation exhaust flow over a 30-day period. No liquids escape from the vaults during the accident.
Computer code RADTRAD 3.03 (Reference 9) is used to calculate the whole body dose resulting from the LHUT rupture using the semi-infinite cloud submersion model, and using air submersion dose coefficients provided in Table III.1 of Federal Guidance Report 12 (Reference 10) and inhalation dose conversion factors provided in Table 2.1 of Federal Guidance Report 11 (Reference 11). The reactor coolant isotopic concentrations based on 1% fuel defects are provided in Table 11.1-11A. Atmospheric dispersion factors used in the analysis are given in Table 2.3-145. The dose consequences at both the Exclusion Area Boundary (EAB) and the Low Population Zone (LPZ) due to airborne releases following a LHUT Rupture are estimated to be below the acceptance criteria of 0.5 rem whole body and 3 rem thyroid.
A similar assessment was also performed for the Volume Control Tank (VCT) rupture.
Though the VCT tank is PG&E Design Class I, the dose consequence analysis for the VCT tank rupture conservatively uses an acceptance criteria, the commitment provided 11.2-19 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE in DCPP UFSAR Section 3.2.2.1.2 for acceptability of dose consequences at the site boundary for a failure in a PG&E Design Class II system.
The VCT is used as part of the CVCS to collect the excess water released from the RCS during modes 1 through 6, which is not accommodated by the pressurizer. For a complete description of the CVCS and the VCT in all modes of operation refer to Section 9.3.4.
The liquid processed through the volume control tank contains dissolved fission and activation products, as well as undissolved radioactive noble gases. A spray nozzle located inside the tank on the inlet line strips part of the nobles gases from the incoming liquid, and these gases are retained in the VCT vapor space. In addition, an overpressure of hydrogen cover gas is provided for the tank to control the hydrogen concentration in the reactor coolant.
The VCT is located in a vault which is a PG&E Design Class I structure, so that in the event of a rupture or spill all liquids are retained in the vault. The volume of the tank vault is sufficient to contain the full contents of the tank without spillage from the vault.
Any gases released from the VCT are collected by the auxiliary building ventilation system and discharged via the auxiliary building vent.
In the evaluation of the VCT rupture accident, the following fission product accumulation and release assumptions are used for the design basis case:
(1) The reactor has been operating at full power with 1 percent defective fuel for an equilibrium core cycle.
(2) The volume control tank contains its maximum equilibrium inventory of radioactivity at the time of the accident. The failure of the tank releases the entire tank contents to the VCT vault.
(3) All of the noble gases and varying amounts of the iodines are released, unfiltered, from the VCT vault to the environment, via the plant vent. The release is treated as a ground level release.
(4) All of the noble gases are exhausted to the environment over a 2-hour time period, or at the rate of the VCT ventilation exhaust flow, whichever results in a more rapid release rate.
(5) The iodine concentration in the VCT vault air space and ventilation exhaust flow is based on an equilibrium iodine distribution balance between the spilled VCT liquid and the air, and is dependent on the temperature, pH, and concentration of iodine in the spilled fluid. The iodines are released to the environment as they evolve out of the spilled liquid at the rate of the VCT vault ventilation exhaust flow over a 30-day period. No liquids escape from the vaults during the accident.
11.2-20 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE Computer code RADTRAD 3.03 (Reference 9) is used to calculate the whole body dose resulting from the VCT rupture using the semi-infinite cloud submersion model, and using air submersion dose coefficients provided in Table III.1 of Federal Guidance Report 12 (Reference 10) and inhalation dose conversion factors provided in Table 2.1 of Federal Guidance Report 11 (Reference 11). The reactor coolant isotopic concentrations based on 1% fuel defects are provided in Table 11.1-11A. Atmospheric dispersion factors used in the analysis are given in Table 2.3-145. The dose consequences at both the EAB and the LPZ due to airborne releases following a VCT Rupture are estimated to be below the acceptance criteria of 0.5 rem whole body and 3 rem thyroid.
11.2.3.13 General Design Criterion 70, 1967 - Control of Releases of Radioactivity to the Environment 11.2.3.13.1 Current Operational Releases The actual releases from the plant site are summarized in the Annual Radioactive Effluent Release Report to the NRC. The report summarizes the liquid, gaseous, and solid radwastes that were released from the site for the past year and provides the calculated dose to the public, which is calculated using the offsite dose calculation manual (ODCM). Releases from DCPP have routinely demonstrated compliance within the general provisions of, and dose limits established in, 10 CFR Part 20 and 10 CFR Part 50.
11.2.3.13.2 Release Points The four major release pathways are as follows:
(1) from the LRS to the discharge structure via either the Unit 1 or Unit 2 ASW discharge lines (refer to Figures 11.2-2, 11.2-3, and 11.2-9);
(2) from the Unit 1 or Unit 2 SGBD:
(a) via the SGBD tanks to the discharge structure via the respective unit's discharge conduit (refer to Figures 11.2-4 and 11.2-9);
(b) via diversion from the SGBD recycle line to the main condenser circulating water discharge.
(3) from the turbine building sump to the discharge structure via either the Unit 1 or Unit 2 turbine-generator building sump discharge line (refer to Figure 11.2-5).
(4) from the condensate demineralizer regenerant system via either the high conductivity tank (HCT) or the low conductivity tank (LCT).
11.2-21 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE Other minor discharge pathways exist. Those identified pathways, monitored radiologically, are included in the ODCM and/or implementing procedures.
The LRS is described in Section 11.2.2. The other three main discharge pathways are described in Sections 11.2.3.13.2.1 through 11.2.3.13.2.3 below.
11.2.3.13.2.1 Turbine Building Drain System The concentration of radioactivity in the turbine building drains is expected to be low, even in the event of significant primary-to-secondary SG leakage. The radiation level and flow of liquid from the turbine building drains are monitored at the oily water separator to verify that there are no unaccounted for or unexpected releases from the turbine building drains. If significant radioactivity is detected coming from the turbine building drains, the discharge can be routed for evaluation and disposition. The monitoring system is in conformance with Regulatory Guide 1.21, Revision 1 (Reference 8) and General Design Criterion 4, 1967.
Turbine building sump wastes are normally released to the environment via each unit's circulating water discharge structure (refer to Figure 11.2-9). A detailed piping and instrumentation schematic of the turbine building sump systems is shown in Figure 3.2-27.
11.2.3.13.2.2 Steam Generator Blowdown System The SGBD system for each unit provides two processing paths. One path discharges blowdown flow to the environment via the SGBD tank and the circulating water discharge tunnel. The other path recycles blowdown flow to the main condenser circulating water discharge via the blowdown treatment system and/or the blowdown treatment bypass line. The recycle path can discharge a portion of blowdown flow to the discharge tunnel. Blowdown flow for each unit can be directed to either blowdown path alone, or to both paths simultaneously.
During plant operation, SG water collects suspended and dissolved solids that are brought in by the feedwater. Water must be blown down from the SGs to maintain low solids concentration for efficient operation (Reference 1).
The blowdown flow may be directed to either or both the discharge and recycle paths for a total blowdown flow of approximately 400 gpm per unit to maintain water chemistry and low solids concentration. If activity is detected at preset levels in the blowdown system, the blowdown will be automatically isolated from the discharge path and blowdown flow will be limited to the recycle path at up to 150 gpm per unit.
Activity in the blowdown that is discharged to the circulating water tunnel is continuously recorded by R-23. In the event that activity is released via the SGBD tank vent, the 11.2-22 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE quantity is calculated based on the continuous readings recorded by R-19. Activity released to the environment is calculated as described in the ODCM.
The SGBD system in the recycle configuration is typically used to recover blowdown for return to the condensate system. The normal flow path for blowdown recycling is through the flash tank to the heat exchanger and to the main condenser. A prefilter and a mixed bed demineralizer, which are normally bypassed, are available as part of the system for use in the event of a primary-to-secondary leak. When used, the prefilter removes both radioactive and non-radioactive suspended solids and the mixed bed demineralizer removes both radioactive and non-radioactive dissolved anions and cations. Effluent from the filter and demineralizer set could be returned through a resin trap filter to the condensate. The mixed bed resin is replaced when exhausted.
A description of the design bases, on-line monitoring, isolation criteria, design codes, system description, safety evaluation, inspection, and testing of the SGBD system is provided in Section 10.4.8.
11.2.3.13.2.3 Condensate Demineralizer Regenerant Solution The condensate demineralizer regenerant solution is the waste created from regenerating anion and cation resin used to clean water in the main condenser. The resin is regenerated with sulfuric acid and sodium hydroxide. The HCT normally receives the initial rinse water that may contain most of the acid, caustic, and contaminants removed from the resin. The LCT normally receives cleaner water used as a final rinse of the resin. The concentration of radioactivity in both the HCT and the LCT is typically not detected, unless blowdown is isolated or if a primary-to-secondary leak is present.
The HCT is discharged as a discrete batch. The tank pH is adjusted within an acceptable range consistent with national pollutant discharge elimination system (NPDES) and other state requirements. The tank is then recirculated, sampled and analyzed prior to issuing a discharge permit.
The LCT is normally discharged as a discrete batch. The tank is recirculated, sampled and analyzed prior to issuing a discharge permit. In some cases, the LCT is allowed to discharge as a continuous discharge for a period of time. In this configuration, more than one sample is taken during the discharge period to ensure that the discharge remains within limits.
11.2.3.13.2.4 Typical Volumes Released The following tables provide an approximation of routine plant discharge volumes.
These are not limiting volumes. Volumes can change as defined in the site procedures as long as 10 CFR Part 20, and 10 CFR Part 50, Appendix I criteria are maintained.

The hole drilled through the ball allows for unidirectional pressure relief (one end of the hole sees the environment inside the pipe while the other end of the hole sees the inside of the valve body). This ensures that the valves meet the requirements of Generic Letter 96-06, September 1996.
11.2.4 TESTS AND INSPECTIONS Tests and inspections of the LRS are done in accordance with plant procedures.

In addition to releases from the GRS, other releases of radioactive gases from the plant are possible under some operating conditions; for example, in periods during which primary coolant system leakage occurs. These additional pathways that can, under some plant operating conditions, release radioactive gases are:
(1) Containment purge (refer to Section 9.4.5) 11.3-3 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE (2) Auxiliary building ventilation (refer to Section 9.4.2)
(3) Fuel handling building ventilation (refer to Section 9.4.4)
(4) Main condenser air ejector (refer to Section 10.4.1)
(5) Gland steam condenser (refer to Section 10.4.3)
(6) SGBD system (refer to Section 10.4.8)
(7) 10 percent atmospheric dump valves (refer to Section 10.4.4)
(8) Main steam and reheat relief valves (refer to Sections 10.2 and 10.3)
(9) Solid radwaste storage building (RSB) ventilation (refer to Section 11.5)
(10) Laundry facility ventilation (refer to Section 11.3.3.10)
(11) Condenser vacuum pump (refer to Section 10.4.2)
The GRS is designed to process radioactive gases consisting primarily of nitrogen and hydrogen with low levels of oxygen. The gases are collected by the vent header system from various primary and auxiliary systems. Radioactive or potentially radioactive gaseous wastes result from collection of excess cover gas in the LHUTs, degasification in the volume control tank, and cover gas displaced in the pressurizer relief tank and RCDT. A piping schematic for the GRS is shown in Figure 3.2-24.
Each unit has a vent header network and surge tank. Gases collected by the vent header system are routed to the surge tank, which is equipped with a safety relief valve to prevent overpressurization.
Each unit's surge tank feeds that unit's waste gas compressor and/or a shared spare compressor through a pressure control valve set to maintain constant compressor suction pressure. The system is designed such that the shared spare compressor will automatically start if the pressure in the surge tank rises above 3 psig. An oxygen monitor on the moisture separator discharge limits the concentration of oxygen that can be fed to the gas decay tanks. The monitor actuates an alarm at 2 percent oxygen concentration and trips the compressors at 4 percent.
The compressor discharge is routed into a network of valves feeding the gas decay tanks. Based on downstream conditions and operator selection, the system controls the positioning of these valves. One tank will be filling, with one tank on standby, and one tank being used for cover gas. The system will automatically switch to the standby tank when the fill tank reaches 100 psig. Should this fail to happen, the system will alarm when the tank reaches 105 psig.
11.3-4 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE The gas decay tanks are provided for the holdup of radioactive gases prior to release to the environment. The size and number of gas decay tanks was selected to provide capability to hold gases for 45 days when necessary (to allow decay). The holdup time required is that which would result in releases that are in compliance with release rate and dose limits. Each gas decay tank may be operated as a cover gas supply for the LHUTs. Normal coolant letdown then displaces the gases back into the GRS. This process effectively increases the volume of storage available for gaseous holdup.
The sampling system associated with the GRS is used to monitor oxygen content of the gases in the system and to collect grab samples for oxygen concentration analysis.
Sample points exist in this system including all influent sources and each of the gas decay tanks. These sample points may be monitored via grab samples which may be taken from manual sample taps. The gas analyzer is equipped with a sample tap for taking bottled samples to undergo radiological testing.
11.3.2.1 Gaseous Radwaste System Operation The GRS handles gaseous discharge from the various sources. The volume of gases originates from displaced cover gas in the LHUTs. The gaseous flow is discharged to the vent header and routed to the surge tank.
The suction pressure to the normally operating compressor is maintained at approximately 0.5 psig via a pressure regulator on the surge tank outlet. During normal operation, the waste gas compressor starts and stops based on surge tank pressure to maintain a nominal 1.1 psig to 2.0 psig in the surge tank. If a control malfunction occurs causing the compressor to continuously operate, a recycle valve would open at a nominal 0.9 psig pressure in the surge tank, returning gases from the moisture separator. This supplies gases back to the compressor suction preventing evacuation of the compressor suction piping. In addition, if the LHUT header pressure is at or below the setpoint (nominally 0.75 psig), a recycle valve from the gas decay tanks opens to maintain the cover gases in the LHUTs.
A shared Unit 1 and Unit 2 spare compressor will start on a high surge tank pressure of a nominal 3 psig. The waste gas compressor discharges into a gas decay tank through a series of automatic valves. When the decay tank is filled to a nominal 100 psig, the inlet valve to the filled tank closes and the inlet valve to a standby tank opens. Should this fail to happen, a high pressure alarm sounds at a nominal 105 psig. The remaining tank is now positioned as the standby tank with the filled tank isolated for decay and release.
11.3.2.2 System Design The GRS, including the gas analyzer package, is designed and fabricated as PG&E Design Class II. The equipment and piping code classifications are listed in Table 3.2-
- 3. The design and operating parameters for the GRS equipment are shown in Table 11.3-1.
11.3-5 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.3.2.3 Plant Releases 11.3.2.3.1 Current Operational Releases Refer to Section 11.3.3.10 for a discussion of current operational releases from the GRS.
11.3.2.3.2 Pre-Operational Estimated Release Evaluation HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
The following information provides historical perspective demonstrating that DCPP's anticipated operation would result in releases within applicable regulatory limits. This information does not necessarily reflect current operating conditions or practices.
The potential release pathways for radioactive gases have been described in previous paragraphs. Table 11.3-2 lists the estimated annual releases for the Design Basis Case, and Table 11.3-3 lists the estimated annual releases for the Normal Operation Case. The assessments of total curies released via each of the various pathways are discussed below. All release calculations were performed using the EMERALD-NORMAL (Reference 1) computer code.
Table 11.3-4 lists the estimated annual gaseous radwaste flows. Tables 11.3-5 through 11.3-8 list the estimated activities in the gas decay tanks and the volume control tank for the Design Basis and Normal Operation Cases.
For the release from venting of the gas decay tanks, it was assumed that the full volume of primary coolant is degassed twice a year, and the quantities of radioactive gases released are listed in Table 11.3-2 for the Design Basis Case and in Table 11.3-3 for the Normal Operation Case.
Containment venting releases are based on an assumed leakage of 1 percent of the primary coolant noble gas inventory and 0.001 percent of the primary coolant iodine inventory per day to the containment. It was assumed that the containment air is purged 24 times a year, and that the containment air is first circulated through the charcoal filters (refer to Section 9.4.5) if the plant has been operating with significant primary coolant leakage to the containment. This recirculation is assumed to reduce the airborne iodine content by 98 percent, based on a filter DF of 10 for iodine, a circulation flowrate of 24,000 cfm for 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br />, a containment free volume of 2.6 x 106 cubic feet, and a mixing efficiency of 70 percent. The resulting releases of iodine and noble gases for the Normal Operation Case are provided in Table 11.3-3.
In the event of leakage of primary coolant to the auxiliary building, the auxiliary building ventilation system can become a release pathway. In the calculation of release via this pathway, in the Normal Operation Case, it was assumed that primary coolant leakage is 160 pounds per day, with a partition factor of 1 for noble gases and 0.0075 for iodine, 11.3-6 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE with no iodine filtration in the ventilation system. The calculated releases via this pathway are provided in Table 11.3-3.
Because of the cleanup of the spent fuel pool water, the very large iodine removal capability of the water, the long decay times for noble gases and iodines in fuel rods handled in the pool, low fuel temperatures, and opportunity for prior release of gases in the containment, the amounts of iodine and noble gases released from the spent fuel pool to the environment under normal conditions are small. In the calculation of the release via this pathway, it was assumed that one-third of a core of spent fuel with 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> decay is placed in the spent fuel pool at the beginning of an operating cycle.
Radionuclides diffuse through defects in fuel elements when cold at a rate 105 less than at normal core operating temperature. A partition factor of 0.001 was assumed for iodine and 1 for noble gases in the pool. The fuel handling building ventilation charcoal filter system was assumed to be 90 percent efficient for iodine removal. The calculated releases via this pathway are provided in Table 11.3-3.
Releases from the waste concentrator condenser vent were assumed to be negligible, and small amounts of gas that are released via this mechanism were included in the analysis by conservatively assuming that they are vented to the atmosphere before entering the GRS.
During periods when primary-to-secondary leakage exists, some release of noble gases and iodine will occur via the main condenser air ejector. To calculate these releases, it was assumed that all noble gases are transferred directly to the condenser vapor space, where they are released through the ejector after some decay. The parameters used in the calculation are provided in Tables 11.1-23 through 11.1-25. These assumptions are consistent with those provided in NUREG-0017, April 1976 (Reference 2). Five percent of the iodine leakage from the primary to the secondary system is assumed to be in volatile form and to behave in a manner similar to a noble gas at SG operating temperatures. A partition factor of 0.15 is assumed for volatile iodine in the condenser, and zero for nonvolatile iodine, so the iodine release from this pathway is entirely in volatile form. The activity releases via this pathway are provided in Table 11.3-3.
A small potential source of activity release exists from the gland steam condenser.
Because of the small steam flowrate used, however, both the noble gas and the iodine release rates via this mechanism were assumed to be negligible compared with the air ejector releases, and this mechanism was not calculated separately.
The SGBD tank vent was not considered to be a significant source of iodine release for the purposes of the offsite dose calculations since the blowdown tank was not expected to be used during periods when significant activity is present in the blowdown.
Significant release via the 10 percent atmospheric dump valves and main steam and reheat relief valves was not expected under normal operating conditions.
11.3-7 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE A small potential source of gaseous activity release exists from the laundry/RSB and solid radwaste storage facility (SRSF) ventilation systems. However, because of the degassed nature of contaminated materials that enter these facilities, noble gas release rate via these pathways were assumed to be negligible compared with other listed pathways, and therefore were not included. Similarly, since iodine will not be gaseous, iodine releases via these pathways were not included.
As a result of normal secondary system steam and water leakage, some iodines and noble gases will escape to the environment if significant activity exists in the secondary system. For the Normal Operation Case, a water leakage of 5 gpm was assumed, along with a steam leakage of 1700 lb/hr. The releases via this pathway are also listed in Table 11.3-3.
During plant startup after a cold shutdown, small quantities of radioactive gases may be released from the vacuum pumps (when the condenser is pumped down) and from the cover gas of the LHUTs. Gases from the LHUTs are processed by the GRS, but the discharge from the condenser is vented directly to the atmosphere. Calculations were performed to evaluate the contribution to the total annual air dose at the site boundary in the NW sector of gases released from the condenser during startup. The results of these calculations are listed in Table 11.3-9. Additional assumptions used in the calculations are:
(1) Initial secondary system activity equal to equilibrium levels with 0.12 percent fuel defects and 100 pounds per day primary-to-secondary leakage (Normal Operation Case).
(2) An "equivalent downtime" was used that is equal to a step change from full power to cold shutdown, a 24-hour down-time, and a step change back to full power.
(3) During shutdown, all noble gases were assumed to accumulate in the condenser vapor space; an effective partition factor of 0.15 is assumed for iodine between the secondary system water and the condenser vapor space for volatile iodine species, and zero for nonvolatile iodine.
(4) All airborne condenser activity is immediately released to the environment on startup. All iodine released was assumed to be volatile, and therefore not to be absorbed into food pathways. The critical dose point is considered to be the site boundary in the NW sector.
This analysis was performed to demonstrate that DCPP normal operation radiological effluents meet the criteria of 10 CFR Part 50 Appendix I. This analysis is conservative and bounds DCPP current operation. This analysis was performed prior to plant operation and would be modified only if a design change or operational change rendered it non-conservative.
11.3-8 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.3.2.4 Dilution Factors 11.3.2.4.1 Current Operational Dilution Factors The meteorological program is discussed in detail in Section 2.3. All current plant releases are calculated in the Annual Radioactive Effluent Release Report, using meteorological conditions derived from 5-year average meteorological data.
11.3.2.4.2 Pre-Operational Dilution Factors HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
The pre-operational evaluation values of dilution factor (/Q) used in the calculation of annual average offsite radiation dose are provided in Table 11.3-11 for the locations specified in Table 11.3-10. The values of deposition rate (D/Q) used in the calculation of annual average offsite radiation dose are provided in Table 11.3-12 for the locations specified in Table 11.3-10. The D/Q values were derived from Figure 7 of Regulatory Guide 1.111, March 1976 (Reference 3) for a ground level release.
The resulting pre-operational evaluation maximum offsite annual average atmospheric activity concentrations in each onshore sector are provided in Table 11.3-13 for the Design Basis Case and in Table 11.3-14 for the Normal Operation Case.
11.3.2.5 Doses 11.3.2.5.1 Current Operational Doses Refer to Section 11.3.3.11 for a discussion of current operational doses from the GRS.
11.3.2.5.2 Pre-Operational Doses HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
Pre-operational dose calculations were performed at the critical distances for each age group and existing dose pathways in each onshore sector within 5 miles of Unit 1. The critical distances assumed in each sector are provided in Table 11.3-10. The milk cow and milk goat food pathways were not identified within 5 miles of the plant and were therefore not considered.
The models used to calculate the offsite radiation doses are those discussed in Regulatory Guide 1.109, March 1976 (Reference 4) for a ground level release. The standard usage factors provided in Regulatory Guide 1.109, March 1976 were used, as well as the standard decay times, transfer factors, and dose conversion factors. Since a ground level release was assumed, the gamma total body and air doses were calculated using the semi-infinite cloud model described in Regulatory Guide 1.109, March 1976, which gives generally conservative results.
11.3-9 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE The results of the offsite dose calculations are presented in Tables 11.3-15 through 11.3-29 for the Design Base Case, and in Tables 11.3-30 through 11.3-44 for the Normal Operation Case. Actual results obtained from the environmental radiological monitoring program are discussed in Section 11.6. On the basis of the calculated estimates of radiation dose presented in Tables 11.3-15 through 11.3-44 and the results of the radiological monitoring program, it can be concluded that, under normal conditions, including consideration of anticipated operational occurrences, the potential dose from gaseous effluents from DCPP Unit 1 and Unit 2 will be well within the dose limits provided in 10 CFR Part 50, Appendix I.
11.3.3 SAFETY EVALUATION 11.3.3.1 General Design Criterion 2, 1967 - Performance Standards The GRS is designed to withstand the DE (refer to Section 11.3.3.15). This design protects the GRS, ensuring its design functions can be performed during the DE.
The waste gas compressor seal water coolers are analyzed to meet DE, Double Design Earthquake (DDE) and Hosgri Earthquake (HE) as detailed in Section 9.2.2.3.1.
11.3.3.2 General Design Criterion 3, 1971 - Fire Protection The gases directed into the decay tanks being filled during waste gas compressor operation are continuously monitored for oxygen content via oxygen analyzer CEL 75 and 76, which alarm at 2 percent oxygen concentration. However, hydrogen concentration in the system is not monitored as its concentration is assumed at all times to be 4 percent (the flammability limit for hydrogen is 6 percent oxygen concentration) or more by volume for all plant operating modes. In this manner, the potential for explosive hydrogen/oxygen mixtures will be mitigated.
The capability exists for diluting the gas with nitrogen (refer to Figure 3.2-24) using pneumatically operated valves controlled from the auxiliary building control board digital system. In the event that dilution with nitrogen is necessary, a grab sample could be taken for isotopic analyses from the gas decay tanks and waste gas sources as required by the plant Technical Specifications.
11.3.3.3 General Design Criterion 4, 1967 - Sharing of Systems One of the three waste gas compressors, the swing compressor, is shared between DCPP Unit 1 and Unit 2. Cross-tie valve FCV-417 allows any waste gas compressor outlet to be directed to either unit's waste gas decay tanks. The swing compressor and the waste gas storage tanks have no safety functions; therefore the sharing does not impair safety on either unit.
11.3-10 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.3.3.4 General Design Criterion 11, 1967 - Control Room Radiation indication and high radiation alarms for gas decay tank effluent are provided in the main control room. Operator actions in the event of high radiation indication are controlled by plant procedures.
11.3.3.5 General Design Criterion 12, 1967 - Instrumentation and Control Systems The GRS is controlled from the auxiliary building control board digital system. System instruments provide signals to alarm on the auxiliary building control board digital system to warn of abnormal conditions.
11.3.3.6 General Design Criterion 17, 1967 - Monitoring Radioactivity Releases Batch preparation and sampling is used to document GRS discharge to the environment. In addition, instrumentation is provided in the control room and on the auxiliary building control board digital system to monitor GRS radioactive releases.
The gas decay tank discharge gas monitor (R-22) continuously monitors the gaseous discharge from the gas decay tanks. A high-radiation signal alarms on the main control board and on the auxiliary building control board digital system and closes the gas decay tanks discharge valves.
Refer to Section 11.4.2.1.2.1 and Table 11.4-1 for additional information.
11.3.3.7 General Design Criterion 18, 1967 - Monitoring Fuel and Waste Storage Instrumentation is provided in the control room and on the auxiliary building control board digital system for conditions that might contribute to radiation exposures from the GRS.
The auxiliary building control board digital system area monitor (R-10) continuously monitors for high radiation in the auxiliary building that may indicate a rupture of a LHUT or other storage tank. Indication is provided in the control room and on the auxiliary building control board digital system.
The gas decay tank cubicle radiation monitors (R-41, R-42, and R-43) continuously monitor noble gas activity in gas decay tanks 1, 2, and 3, respectively. The detectors are located in compartments adjacent to the decay tanks and provide indication on the auxiliary building control board digital system.
Refer to Section 11.4.2.1.2.1 and Table 11.4-1 for additional information.
11.3-11 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.3.3.8 General Design Criterion 68, 1967 - Fuel and Waste Storage Radiation Shielding Each waste gas decay tank is located in an individual shielded vault and is equipped with a safety relief valve that discharges to the plant vent.
11.3.3.9 General Design Criterion 69, 1967 - Protection Against Radioactivity Release from Spent Fuel and Waste Storage As discussed in Section 11.3.2.2, the GRS is designed and fabricated as PG&E Design Class II. In accordance with UFSAR Section 3.2.2.1.2, fluid systems and fluid system components that contain or may contain radioactive material, but whose failure would not result in calculated potential exposures in excess of 0.5 rem whole body (or its equivalent to parts of the body) at the site boundary, may be classified as PG&E Design Class II.
As part of the acceptability of its PG&E Design Class II classification, an evaluation was performed of the dose consequences at the site boundary of a Gas Decay Tank (GDT) failure accident. Three gas decay tanks are provided for each unit to afford operating flexibility and allow one or more tanks to be isolated from the rest of the system for an extended period of time. Most of the gas stored in the decay tanks is nitrogen cover gas displaced from the liquid waste holdup tanks. The radioactive components are principally the noble gases krypton and xenon, the particulate daughters of some of the krypton and xenon isotopes, and trace quantities of halogens.
In the evaluation of the GDT failure accident, the fission product accumulation and release assumptions for the tank rupture are consistent with those of NRC Safety Guide 24, March 1972 (Reference 5). These assumptions are:
(1) The reactor has been operating at full power with 1 percent defective fuel and a shutdown to cold condition has been conducted at the end of an equilibrium core cycle.
(2) All noble gases have been removed from the primary cooling system and volume control tank and transferred to the gas decay tank that is assumed to fail. Credit is taken for radioactive decay during transfer.
(3) The failure occurs immediately on completion of the waste gas transfer, releasing the entire maximum contents of the tank to the auxiliary building and exhausted to the environment via the plant vent assuming a ground level release. The assumption of the release of the noble gas inventory from only a single tank is based on a design that allows all gas decay tanks to be isolated from each other when they are in use.
11.3-12 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE (4) All of the noble gases are exhausted from the auxiliary building over a 2-hour time period or at the rate of the ventilation exhaust flow whichever results in a more rapid release rate.
Computer code RADTRAD 3.03 (Reference 6) is used to calculate the whole body dose resulting from the GDT rupture using the semi-infinite cloud submersion model and using air submersion dose coefficients provided in Table III.1 of Federal Guidance Report 12 (Reference 7). The reactor coolant isotopic concentrations based on 1% fuel defects are provided in Table 11.1-11A. Atmospheric dispersion factors used in the analysis are given in Table 2.3-145. The dose consequences at both the Exclusion Area Boundary (EAB) and the Low Population Zone (LPZ) due to airborne releases following a GDT Rupture are estimated to be below the acceptance criteria of 0.5 rem whole body and 3 rem thyroid.
The quantity of radioactive material contained in each gas decay tank is limited to less than or equal to 105 curies noble gases (considered as Xe-133 equivalent), to ensure that in the event of an uncontrolled release of the tank's contents, the resulting whole body exposure to a member of the public at the nearest site boundary will be less than 0.5 rem.
11.3.3.10 General Design Criterion 70, 1967 - Control of Releases of Radioactivity to the Environment Each gas decay tank is equipped with a flow control valve connected to the plant vent.
The discharge of each valve is routed into a common flow control valve that provides redundant means of isolation and requires manual operation to ensure no inadvertent venting may take place.
Downstream of the common flow control valve is a radiation monitor that controls a downstream control valve. If the activity in the discharging waste gas exceeds its upper limit, the control valve closes, terminating the release. The final processing of waste gas prior to release to the atmosphere is by a high-efficiency particulate air (HEPA) filter located just downstream of the radiation control valve and just upstream of the plant vent.
Most radwaste gas releases are routed to the plant vent, with the exception of any release from the 10 percent atmospheric dump valves, main steam relief valves, reheat valves, SRSF, RSB/laundry facility exhaust, chemical laboratories exhaust, turbine building exhaust, condenser vacuum pump exhaust, and any miscellaneous steam leakage. Locations of the release points in the plant are shown in Figure 11.3-4. The design exit velocity at the plant vent is 17 m/sec during normal plant operation.
The actual gaseous releases are performed in accordance with approved plant procedures. The plant vent pathway is continuously monitored for noble gases, particulates, and iodines (refer to Section 11.3.3.12).
11.3-13 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE The containment atmosphere is sampled and evaluated prior to release via the plant vent pathway during power operations. During periods of maintenance and refueling outages most releases continue via the plant vent pathway. However the containment equipment hatch may be open at times during maintenance resulting in direct communication between the air inside containment and the outside air. If flow out of the containment equipment hatch is detected, containment air is evaluated per plant procedures to characterize the release for reporting.
Tritium is also released via the plant vent system mainly due to evaporation from the spent fuel pool.
11.3.3.11 10 CFR Part 20 - Standards for Protection Against Radiation Occupational doses to plant personnel from the GRS are maintained ALARA by:
(1) Shielding in locations that contain GRS equipment (refer to Section 12.1.2)
(2) HVAC systems that direct air flows for controlled discharge and provide filtration of radioactive materials (refer to Section12.2.2)
(3) Monitoring and alarming of potentially radioactive releases from the GRS (refer to Section 11.3.3.4)
(4) Administrative controls for working in areas of potentially high radioactivity (refer to Section 5 of the Diablo Canyon Quality Assurance Program Description)
Current operational offsite doses are calculated in accordance with the ODCM contained in site-approved procedures in accordance with 10 CFR Part 20 and appropriate NRC regulatory guides.
Technical Specifications require programs for the control of radioactive effluents and for maintaining the doses to members of the public from radioactive effluents within the regulatory limits of 10 CFR Part 20. Doses are reported on quarterly and annual bases.
The programs are implemented by plant procedures, and include remedial actions to be taken whenever the program limits are exceeded.

(1) Providing appropriate holdup capacity for retention of gaseous effluents containing radioactive material (refer to Section 11.3.2)
(2) Continuously monitoring the GRS for leakage (refer to Section 11.3.2)
(3) Sampling all discharges prior to release to the environment and using acceptable dilution factors (refer to Section 11.3.2)
Technical Specifications require programs for the control of radioactive effluents and for maintaining the doses to members of the public from radioactive effluents within the regulatory limits of 10 CFR Part 50, Appendix I. Doses are reported on quarterly and annual bases. The programs are implemented by plant procedures, and include remedial actions to be taken whenever the program limits are exceeded.
11.3.3.13 40 CFR Part 190 - Environmental Radiation Protection Standards for Nuclear Power Operations Current operational doses from all sources to members of the public are summarized in Annual Radioactive Effluent Release Reports. During preparation of the report, operational doses are compared to the respective 40 CFR Part 190 limit, as implemented under 10 CFR 20.1301(e) (refer to Section 11.3.3.11).

11.3.3.15 Regulatory Guide 1.143, Revision 1, October 1979 - Design Guidance for Radioactive Waste Management Structures, Systems, and Components Installed In Light-Water-Cooled Nuclear Power Plants The GRS is PG&E Design Class II (refer to Section 11.3).
The PG&E Design Class II GRS equipment and piping that are applicable to Regulatory Guide 1.143, Revision 1 are designated PG&E QA Class R. The portions of the GRS 11.3-15 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE that are intended to store or delay the release of gaseous radioactive waste are seismically supported to withstand the DE and are designated PG&E Piping Symbol F.
The remaining portions of the GRS are designated PG&E Piping Symbol H or E, as applicable.
11.3.3.16 NUREG-0737 (Items II.F.1 and III.D.1.1), November 1980 - Clarification of TMI Action Plan Requirements Item II.F.1 - Additional Accident Monitoring Instrumentation:
Position (1) - The GRS primarily discharges to the plant vent. ER noble gas effluent monitoring is installed in the plant vent and is designed to function during accident conditions (refer to Sections 7.5.2.3 and 11.4.2.1.2.1).
Position (2) - Installed capability is provided in the plant to obtain samples of the particulate and iodine radioactivity concentrations that may be present in the gaseous effluent being discharged to the environment from the plant under accident and post-accident conditions. The technical support center (TSC) laboratory is available for onsite testing of the containment air samples (refer to Section 11.3.2).
Item III.D.1.1 - Integrity of Systems Outside Containment Likely to Contain Radioactive Material for Pressurized-Water Reactors and Boiling-Water Reactors: The integrity of the GRS is continuously evaluated by monitoring the auxiliary building ventilation exhaust for levels of radiation that may indicate leakage from the GRS (refer to Section 5.2.3.26).
11.3.4 TESTS AND INSPECTIONS All GRS radiation and chemical monitors used in system evaluation are functionally tested and calibrated periodically to ensure the accuracy of measurements. The types of radiation monitors and locations are described in Section 11.4.
Measurements are made on a continuous basis and records are maintained of the quantity of radioactive gases released. Comparison of results provides a check on the continuing performance of the waste gas systems. This approach proves effective in documenting deficiencies and their corrections. The routine radiation monitoring program also detects leakage from the GRS by detecting minute changes in the activity of air in the areas occupied by the system. Appropriate means are used to locate and correct any increase in leakage.
11.3.5 INSTRUMENTATION APPLICATIONS Refer to Section 11.3.3.5 for a discussion of the instrumentation requirements and controls for the GRS.

11.4.1.26 NUREG-0737 (Items II.F.1, III.A.1.2, and III.D.1.1), November 1980 -
Clarification of TMI Action Plan Requirements Item II.F.1 - Additional Accident Monitoring Instrumentation Position (1) - The RMS is designed with noble gas effluent monitors with an ER designed to function during accident conditions.

11.4.2 SYSTEM DESCRIPTION 11.4.2.1 Continuous Monitoring 11.4.2.1.1 General Description The components of the RMS are designed for operation in the following ranges of conditions:
(1) Temperature - An ambient temperature range of 40° to 120°F.
11.4-5 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE (2) Humidity - 0 to 95 percent relative humidity.
(3) Pressure - Components in the auxiliary building and control room are designed for normal atmospheric pressure. Area monitoring system components inside the containment are designed to withstand containment test pressure.
(4) Radiation - Process and area radiation monitors are of a non-saturating design so that they will register full-scale or over range if exposed to radiation levels up to 100 times full-scale indication.
(5) Radiation monitoring equipment is designed and located such that radiation damage to electrical insulation and other materials will not affect their usefulness over the life of the plant.
(6) The RMS is designed such that it can be checked, tested, and recalibrated as required.
The only components of the RMS that are exposed to a wider range of conditions are located in the containment. This includes detectors and associated local alarm and indication equipment for the area-type monitoring channels there. Some of these, namely the low level-normal ops monitors are not expected to operate following a major LOCA. Post-accident high-range gamma monitors are used for post-accident situations.
Most of the control room RMS equipment used for normal operation and anticipated operational occurrences are centralized in cabinets. Data loggers are provided in the RMS cabinets in the control room (refer to Table 11.4-1). Each monitoring channel on the data loggers is sequentially recorded.
Equipment used solely for post-accident monitoring (PAM) is located in additional cabinets in the control room. The digital RMS equipment is located in a six-bay cabinet while the control room pressurization system (CRPS) monitors are in a separate control room rack. Sliding channel drawers are normally used to facilitate maintenance and allow replacement of units, assemblies, and entire channels if needed. It is possible to completely remove the various chassis from the cabinet after disconnecting the cable connectors from the rear of these units.
Detector output is usually measured in either counts per minute (cpm), milliroentgens per hour (mR/hr), roentgens per hour (R/hr), or microcuries per cubic centimeter (Ci/cc). Each channel has a minimum range of three decades. Radiation monitors are listed in Tables 5.2-16 and 11.4-1. The iodine monitors are isotopic I-131 process monitors and read in cpm or Ci/cc.
The RMS is divided into the following subsystems:
11.4-6 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE (1) The process RMS that monitors radiation levels in various plant process streams and effluent paths (2) The area RMS that monitors radioactivity in various areas within the plant The locations of all detectors with respect to plant equipment for Unit 1 are listed in Table 11.4-1. Unit 2 detectors are in corresponding locations. Piping sequence and locations of process detectors are found in appropriate piping schematics, shown as figures in Section 3.2.
11.4.2.1.2 Process Radiation Monitoring System 11.4.2.1.2.1 Description This system, as illustrated in Figure 11.4-1, consists of multiple channels that monitor radiation levels in various plant operating systems. The output from each channel detector except the digital radiation monitors is transmitted to the RMS cabinets where the radiation level is indicated on a meter and recorded by a multipoint recorder (refer to Table 11.4-1). Except for the air particulate/iodine/noble gas monitors in the TSC and the adjacent laboratory, the gas decay tank cubicles, and the SGBD overboard monitor, the RMS cabinets for most process radiation monitors are located in the control room.
The RMS cabinets for the TSC and the adjacent laboratory are located in the computation center. High radiation level alarms are indicated on the RMS cabinets with annunciation on main annunciators. Except for the monitors in the TSC, the adjacent laboratory and some supplementary monitors, the main annunciator for process monitors is at the control board in the control room.
The control board annunciator provides several windows that alarm for input channels (process or area) detecting high radiation. The main annunciator for the TSC and the adjacent laboratory is in the TSC panel annunciator in the computation center.
Verification of which channel has alarmed is done at the RMS cabinets serving that annunciator (refer to Table 11.4-1).
A tabulation of the process radiation monitoring channels is found in Table 11.4-1. The minimum sensitivity is based on a Co-60 background level of 2 mR/hr.
A typical channel contains a completely integrated modular assembly that includes the following:
(1) Log Level Amplifier Accepts detector pulses, performs a log integration (converts total pulse rate to a logarithmic analog signal), and amplifies the resulting output for suitable indicating and recording.
11.4-7 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE (2) Power Supplies Furnishes electrical power for the circuits, relays, alarm lights, and detectors.
(3) Test-Calibration Circuitry Provides a pre-calibrated pulse signal to test channel electronics and a solenoid-operated radiation check source to verify channel operation. A common annunciator on the main control board indicates when a channel is in the test mode.
(4) Radiation Level Meter Provides a dual scale calibrated logarithmically from 101 to 104, and 101 to 106 cpm. The wide-range level signal is also recorded by the data logger recorder.
(5) Indicating Lights Indicate high-radiation alarms, tests, and circuit failures. A number of annunciator windows on the main control board are actuated either on high radiation signal from the channels or from any channel failure. A separate window is lit when channels are placed in the test mode.
However, the digital radiation monitoring system and a few other monitors do not have this test alarm feature.
(6) Bistable Circuits Two bistable circuits are provided: one to alarm on high radiation (actuation point may be set at any level within the range of the instruments), and one to alarm on loss of signal (circuit failure).
(7) Check Source A remotely operated long half-life radiation check source is furnished for each channel. The check source simulates the radiation being monitored.
The check source interaction is sufficient to cause an upscale indication.
The main steam line radiation monitors and the CRPS radiation monitors have a fixed keep alive source mounted directly on the detector. It is used only to keep the channel out of a low fail condition.
The process RMS consists of the radiation monitoring channels described in Items 1 through 28 below. (The prefix numbers, where used with channel identification, indicate monitors associated with Unit 1 or Unit 2; 0 indicates a shared monitor or no unit designation.)
11.4-8 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE The sample lines for the air particulate and gaseous radiation monitors (containment, RHR heat exchanger compartment exhaust, control room, TSC, laboratories, and plant vent) are designed and installed in accordance with the recommendations of Reference 2.
The flow in each of the sample lines is turbulent. Particle deposition due to gravity and Brownian diffusion are assumed to be small since the horizontal runs of the sample lines are short and the sample velocity is high. Long-radius bends are used for all sample lines, including the inlet lines to the monitors, to preclude deposition due to extreme turns. Isokinetic probes are used wherever the sample is taken from a moving airstream. Deposition in the basically vertical sample line runs are assumed to be largely due to turbulent deposition.
The following are process radiation monitors that do not support ESF functions. For those that do support ESF functions, refer to Section 11.4.2.1.4.
(1) Containment - Air Particulate Monitor (1-R-11 and 2-R-11)
This monitor is provided to measure air particulate gamma radioactivity in the containment.
The sampler for this channel takes a continuous air sample from the containment atmosphere. The inlet line from inside the containment is routed through the containment penetration to the monitor, which is located adjacent to the penetration.
The sample is monitored by a scintillation counter-filter paper detector assembly. The filter paper has a collection efficiency of approximately 99% for particles of 0.3 microns or larger.
The particulate matter is collected on the filter paper's constantly moving surface and is viewed by a gamma scintillation detector. The sample is returned to the containment after it passes through the series-connected gas monitor.
The pulse signal is transmitted to the RMS cabinets in the control room.
For activity releases inside containment, the air particulate and gas monitors RE-11 and RE-12 will alarm in the control room.
Lead shielding is provided to reduce the background level to where it does not interfere with the detector's sensitivity.
(2) Containment - Radioactive Gas Monitor (1-R-12 and 2-R-12)
This monitor is provided to measure gaseous beta-gamma radioactivity in the containment. The detector consists of a beta-gamma sensitive Geiger-Mueller (G-M) tube mounted in the monitor container.
11.4-9 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE This channel takes a continuous air sample from the containment atmosphere that passes through the air particulate monitor (1-R-11, 2-R-11), and then through the gas monitor assembly. The sample is circulated in a fixed volume where it is monitored by the radiation detector.
The sample is then returned to the containment. Its output is transmitted to the RMS cabinets in the control room. For activity releases inside containment, the air particulate and gas monitors RE-11 and RE-12 will alarm in the control room.
(3) RHR Heat Exchanger Compartment Exhaust Duct Air Particulate Detector Monitor (1-R-13 and 2-R-13)
This monitor is provided to measure air particulate gamma radioactivity in the RHR heat exchanger compartments' exhaust ducts to detect a leaking recirculation loop component in the event of a LOCA. It operates in the same manner as the containment air particulate monitor.
The sampler for this channel takes a continuous common air sample from the exhaust ducts of both RHR compartments.
An isokinetic probe is installed in each RHR compartment exhaust duct.
The monitor is located in proximity to the sample points.
The sample is monitored by a scintillation counter-filter paper detector assembly. The sample is then returned to the exhaust ducts. Ducts may be sampled individually by use of a selector switch at the console. High radiation is annunciated at the main control board.
(4) Plant Noble Gas Vent Monitor (1-R-14, 2-R-14) (1-R-14R, 2-R-14R)
Each channel consists of a pressurized three liter volume monitored by a beta scintillation detector. RM-14 is part of the normal range (NR) skid.
RM-14R is part of the redundant normal range (RNR) skid. Local indication for these channels is provided by the local radiation processors (LRPs) mounted on their respective skids. Remote indication for these channels is provided by the radiation display units (RDUs) for their respective skids. The RDUs are mounted in the RMS panels in the control room.
11.4-10 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE (5) Condenser Air Ejector Gas Monitor (1-R-15, 1-R-15R, 2-R-15, 2-R-15R)
These channels monitor the discharge from the air ejector exhaust header of the condensers. Gaseous radiation is indicative of a primary-to-secondary system leak. The gas discharge is routed to the plant vent. Both RM-15 and RM-15R share the same detector skid. Local indication for these channels is provided by the wall-mounted LRPs associated with each detector. Remote indication for these channels is provided by RDUs. The RDUs are mounted in the RMS panels in the control room. High radiation is annunciated at the main control board.
(6) Component Cooling Liquid Monitors (1-R-17A, 2-R-17A, 1-R-17B, 2-R-17B)
These channels continuously monitor the component cooling water (CCW) system for radiation indicative of a leak of reactor coolant from the RCS and/or the RHR loop to the CCW. Each channel employs an off-line detector using a bypass line from CCW pump discharge to suction. Due to the discharge piping configuration, however, only one monitor is sampling flow representative of the bulk system when only one CCW heat exchanger is in service. A high-radiation-level signal initiates closure of the valve located in the component cooling surge tank vent line to prevent gaseous radiation release. Adequate lead shielding is provided to reduce the effect of background radiation so that it does not interfere with the detector's sensitivity.
(7) Liquid Radwaste Effluent Monitor (0-R-18)
This channel continuously monitors discharges from the LRS. Automatic valve closure is initiated to prevent further release after a high radiation level is indicated and alarmed, and flow is diverted to the equipment drain receiver tanks. A scintillation detector located in an in-line sampler monitors these effluent discharges. An alarm function is provided on the main control board and the auxiliary building control board digital system.
Adequate lead shielding is provided to reduce the effect of background radiation so that it does not interfere with the detector's sensitivity. In addition, samples from the LRS batches are analyzed in the laboratory.
(8) SGBD Sample Monitor (1-R-19, 2-R-19)
This channel monitors the liquid phase of the secondary side of the SG for radioactivity (which would indicate a primary-to-secondary system leak) providing backup information to that of the condenser air ejector gas monitors. Blowdown samples from each of the four SGs are combined in a common header and the common sample is continuously monitored by a scintillation detector in an in-line sampler assembly.
11.4-11 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE Adequate lead shielding is provided to reduce the effect of background radiation so that it does not interfere with the detector's sensitivity. High activity alarm indications are displayed locally and at the RMS cabinets, with annunciation at the main control board in the control room.
If a high activity alarm occurs, isolation valves in the blowdown and sample lines acting with the valve in the line from the blowdown tank to the discharge structure will close and the blowdown tank liquid effluent will be diverted to the equipment drain receiver tank. Subsequent identification of the leaking SG would then be made by manual override of sample line isolation and drawing separate samples from each SG for analysis.
(9) Gas Decay Tank Discharge Gas Monitor (1-R-22, 2-R-22)
This channel monitors the gaseous discharge from the gas decay tanks.
The detector consists of a G-M tube inserted into an in-line fixed volume container that includes adequate shielding to reduce the background radiation low enough not to interfere with the detector's sensitivity. This channel will alarm on the main control board and auxiliary building control board digital system and close the gas decay tanks discharge valve on a high radiation level signal.
(10) Plant Vent Particulate Monitors (1-R-28, 2-R-28)(1-R-28R, 2-R-28R)
Each channel consists of a fixed particulate filter monitored by a beta scintillation detector. RM-28 is part of the NR skid. RM-28R is part of the RNR skid.

DCPP UNITS 1 & 2 FSAR UPDATE (12) SGBD Tank Liquid Effluent Monitor (1-R-23, 2-R-23)
This channel is provided to continuously measure liquid effluent from the blowdown tank. The channel employs a scintillation detector located in an off-line sample chamber. Adequate shielding is employed to reduce effects of background radiation.
The count rate is handled in the same manner as for the basic RMS.
Output is recorded in conjunction with, and parallel to, the recorded outputs of the flow elements related to the blowdown tank inputs and effluents at a local panel specifically provided for that function. Output is also recorded at the data logger in the RMS cabinets in the control room.
Alarms are provided on the main control board for high and low radiation (instrument failure). A high-radiation signal isolates the blowdown discharge, and diverts blowdown tank liquid effluent to the equipment drain receiver tank.
(13) High-Range Plant Vent Gas Monitor (1-R-29, 2-R-29) Post-accident Monitor This monitor measures high-range gross gamma radioactivity in the plant vent. The detector consists of a shielded ion chamber contiguous to the plant vent and mounted on an adjacent support structure.

The high and fail radiation alarms are also provided on the main control board. The high alarm also alarms in the State of California Office of Emergency Services in Sacramento.
(14) Deleted (15) ER Noble Gas Monitor (1-R-87, 2-R-87)
The ER channel, RM-87, uses a beta scintillation detector operated in the current mode. The ER noble gas detector is less sensitive and the volume of the detection chamber is smaller than those of the NR noble gas channel. The ER chamber is not pressurized. The sample is isokinetically drawn off the plant vent stack at approximately 1/20th the rate of the sample for the NR and RNR skids. The chamber is downstream of two identical trains of particulate and iodine roughing filters/grab samplers.
Alternating between the trains allows removing a grab sample while continuing to monitor the stack. The grab samplers are to be used for assessing post-accident releases of particulates and iodine using laboratory instruments. All of this equipment is mounted on the ER skid.
Local indication for RM-87 is provided on the LRP for the NR Skid.

(22) SRSF and RSB Ventilation Exhaust Air Particulate Samplers (0-RX-55, 0-RX-56)
These samplers consist of in-line particulate filter assemblies that provide the capability to sample and subsequently assess (via laboratory analysis) the, concentrations of radioactive material present in the exhaust from the SRSF and RSB. RX-55 samples the exhaust from the SRSF, and RX-56 11.4-14 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE samples the exhaust from the laundry/respirator cleaning facility and RSB prior to the discharge of these effluent points to the environment.
(23) Oily Water Separator Effluent Monitor (0-R-3)
This channel continuously monitors the turbine building sump retention tank discharge into the oily water separator.

The detectors are located at the decontamination/inspection station in the RSB.
(28) Laundry Processing Room Radiation Monitoring Assembly (0-R-92)
The laundry processing room radiation monitoring channel (R-92) extracts a sample from the air space in the laundry processing room and monitors this sample to determine the radioactivity concentration in the air.
Samples are extracted by a sampling nozzle located in the room and returned to the laundry processing room.
11.4-15 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE 11.4.2.1.2.2 Design Evaluation For ruptures or leaks in the waste processing system, plant area monitors and the vent stack monitor will alarm on an increase in radiation over a preset level. For cases where leaks are involved, the operator may control activity release by system isolation. For inadvertent releases relative to violation of administrative procedures, monitors provide alarms and the means for limiting radioactive releases. The gas decay tank discharge monitor will close the flow control valve in the waste decay tanks discharge line when the radiation level in the line exceeds a preset level. Where liquid waste releases are involved, the liquid radwaste discharge monitor trips shut a valve in the discharge line when the radioactivity in the discharge line exceeds a preset level and redirects the flow to the equipment drain receiver tanks.
For SGBD releases, the blowdown effluent monitor and the blowdown sample monitor isolate the blowdown discharge and will divert the blowdown tank liquid effluent to the equipment drain receiver tanks.
11.4.2.1.3 Area Radiation Monitoring System 11.4.2.1.3.1 Description This system consists of multiple channels that monitor radiation levels in various areas of the plant. The system has low-range monitors for normal operation and high-range monitors for post-accident conditions. These monitors and their locations are listed in Table 11.4-1.
The selection and location of the monitoring areas are based on multiple considerations, including occupancy status of various plant zones, potential for increase in background activity levels due to operations carried out in a particular location, and desirability of surveillance of infrequently visited areas.
A typical channel of the area RMS consists of a fixed-position, gamma-sensitive G-M tube detector. The detector count rate is amplified, and its log count rate is displayed by the readout in the RMS cabinets. The radiation level is indicated locally at the detector and at the RMS cabinets and it is also recorded. Except for the area monitors in the TSC and the adjacent laboratory, most RMS cabinets are located in the control room (refer to Table 11.4-1). The RMS cabinet for the area monitors in the TSC and laboratory is located in the TSC computation center. High-radiation alarms are displayed on main annunciators, on the RMS cabinets, and at the detector location.
The control room annunciator provides several windows that alarm for channels detecting high radiation, except for the monitors in the TSC and laboratory. The main annunciator for high radiation detected by the TSC and laboratory area monitors is the TSC HVAC annunciator located in the computation center. Verification of which 11.4-16 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE channel has alarmed is done at the RMS cabinets. Each channel contains a completely integrated modular assembly (refer to Section 11.4.2.1.2).
The log level amplifier module amplifies the radiation level signal for indication and recording. The module also provides controls for actuation of the channel check source.
A meter is mounted on the front of each readout module and is scaled to read logarithmically (refer to Table 11.4-1). A local meter, scaled logarithmically, is mounted at the detector assembly.
Two mutually redundant high-range containment monitors RE-30 and RE-31 are provided for each unit, each consisting of a detector mounted inside the containment liner to mitigate the effects of local hot spots and to obtain the best "view" of the containment free volume. The units are powered from separate instrument power channels (refer to Section 8.3.1.1.5).
Each detector is a hermetically sealed, stacked, parallel plate, three-terminal guarded ionization chamber, operated in the saturated mode. The detector and its special cable are environmentally qualified to IEEE 323-1974.
Each readout has a range of 1 to 107 R/hr and has high alarm, failure alarm, logarithmic scale recorder, and electronic system and detector checks.
For those radiation monitors that support ESF functions, refer to Section 11.4.2.1.4.
11.4.2.1.3.2 Design Evaluation Radiation detection instruments are located in areas of the plant that house equipment containing or processing radioactive materials. These instruments continually detect, display, and, as appropriate, record operating radiation levels. If the radiation level should rise above the channels pre-determined high alarm setpoint, an alarm is initiated in a control room.
Local annunciation is provided at the detector, with the exception of the high-range containment detectors, to indicate high radiation levels to personnel in the area. The monitoring system is operated in conjunction with regular and special radiation surveys and with chemical and radiochemical analyses performed by the plant staff. Adequate information and warning is thereby provided for the continued safe operation of the plant and assurance that personnel dose does not exceed 10 CFR Part 20 limits.
11.4-17 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE 11.4.2.1.4 Radiation Monitoring Channels that Support Engineered Safety Features 11.4.2.1.4.1 Description Radiation monitoring channels that support ESF functions include the following:
(1) Main Control Room Air Intake Monitor (1-R-25, 1-R-26) (2-R-25, 2-R-26)
These channels monitor air entering the normal air intakes for the control room ventilation system (CRVS) to support the ESF function to initiate Mode 4 CRVS operation.
These monitors use a scintillation type general-purpose detector and have a range of 10-2 to 103 mR/hr. Each monitor has a control room readout module with instrument failure alarm. A high radiation signal provides control room annunciation and automatic actuation.
(2) Containment Purge Exhaust (CPE) Monitors (1-R-44A, 2-R-44A)(1-R-44B, 2-R-44B)
Each channel consists of a beta scintillation detector mounted to the side of the CPE duct. The detectors are mounted diametrically opposed on the 48-inch CPE duct. Their location is downstream of the CPE fan, E-3.
Local indication for each channel is provided by the wall mounted LRPs associated with each detector. Remote indication for each channel is provided by the RDUs. The RDUs are mounted in the RMS panels in the control room. These monitors support an ESF function to close the containment ventilation isolation (CVI) valves in the case of high radioactivity exhausting the containment.
(3) CRPS Ventilation Intake Air Monitor (1-R-51, 1-R-52) (2-R-53, 2-R-54)
These channels monitor air entering the CRPS ducts and support the ESF function to shut down the operating CRPS train and automatically start the opposite units CRPS.
These monitors use G-M tube-type general purpose detectors and have ranges of 10-2 to 104 mR/hr. Each monitor has a control room readout module with instrument failure alarm. A high radiation signal provides control room annunciation and automatic actuation.

This monitor is located near the new fuel storage area and supports the ESF function to transfer the FHBVS to the Automatic Iodine Removal Mode should the pre-determined setpoint be exceeded.
This channel uses a G-M detector and has an indicating range of 10-1 to 104 mR/hr. It provides continuous monitoring and indication with alert and high radiation level alarms in the main control room. Local audible and visual indicators are also provided.
11.4.2.1.4.2 Design Evaluation An evaluation of instrumentation function relative to monitoring and controlling releases of radioactivity from various plant systems is discussed below.
(1) Fuel Handling Inside Containment The air exhausted from the containment through the containment purge and exhaust lines is monitored by RM-44A and RM-44B. In the event that the pre-determined high alarm setpoint levels are exceeded, these radiation monitoring channels will initiate a signal that would cause the closure of the CVI valves and mitigate the consequences of the accident.
(2) Fuel Handling Outside Containment Radiological conditions local to the spent and new fuel storage areas are monitored by RM-58 and RM-59, respectively. These monitors provide local and control room alarm annunciation, and will initiate a change in the mode of operation of the FHBVS to Automatic Iodine Removal Mode in the event that a high alarm setpoint is exceeded.
An evaluation of instrumentation functions relative to monitoring and controlling radiological exposures to control room operators is discussed below.
11.4-19 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE (1) CRVS Normal Air Supply Monitoring The normal air intakes to the CRVS are monitored by RM-25 and RM-26.
MODE 4 operation of the CRVS is automatically initiated upon detection of radioactive contaminants at the normal air intakes.
(2) CRPS Air Supply Monitoring The CRPS air supply piping is monitored for radioactivity by RM-51 and RM-52 (Unit 1) and RM-53 and RM-54 (Unit 2). In the event an accident occurs in one unit, the system automatically selects the pressurization intake train of the opposite unit. With radiation detected at both pressurization intakes, one of the trains will start. However, the operator manually switches to the intake with lower airborne radioactivity.
11.4.2.2 Sampling 11.4.2.2.1 Basis for Selection of Sample Locations Locations for periodic sampling are based on the following:
(1) Sampling of process fluids that contain radioactivity (2) Sampling of process fluids not normally radioactive that may become radioactively contaminated due to some component failure 11.4.2.2.2 Expected Composition and Concentration Because of the diversity of sources of sampled fluids, the activity levels are expected to range from negligible to the reactor coolant concentrations. Concentrated liquid samples may have specific activities higher than that of the RCS.
11.4.2.2.3 Quantity to Be Measured Samples expected to contain radioactivity are analyzed periodically as specified in the radiological monitoring and controls procedures and the chemical analysis procedures of the Plant Manual.
11.4.2.2.4 Sampling Frequency and Procedures Sampling frequency varies according to the sample being analyzed and previous activity level of the sample.

The PG&E Design Class I portions of the RMS are protected from the effects of floods and tsunamis (refer to Section 3.4) and external missiles (refer to Section 3.5).
With the exception of certain PG&E Design Class I portions of the RMS that are located in structures that are vulnerable to tornadoes, PG&E Design Class I RMS equipment are designed to perform their safety functions under the effects of winds and tornadoes (refer to Section 3.3). Those portions that are located in structures that are vulnerable to tornadoes are not required for plant safe shutdown (refer to Section 3.3.2).
11.4.3.2 General Design Criterion 3, 1971 - Fire Protection The RMS is designed to meet the requirements of 10 CFR 50.48(a) and (c) (refer to Section 9.5.1) 11.4.3.3 General Design Criterion 4, 1967 - Sharing of Systems Certain RMS components, as designated in Table 11.4-1, are common to both Unit 1 and Unit 2. All shared RMS components are PG&E Design Class II, perform no safety function, and are isolated from PG&E Design Class I components as described in Sections 7.1.3 and 8.3.1.1.5; therefore safety is not impaired by the sharing.

11.5.2 SYSTEM DESCRIPTION 11.5.2.1 System Inputs The SRS collects the following inputs for processing, packaging, and disposal:
(1) Spent filter/ion exchange media (2) Spent ion exchange resin (3) Spent filter cartridges (4) Miscellaneous dry active wastes (i.e., contaminated paper, rags, clothing, tools, etc.)
The SRS input from each of the plant solid radioactive waste streams is presented in Table 11.5-1.
HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
Tables 11.5-2 and 11.5-4 list the activities of the spent ion exchange resins, the spent filter media, and the spent cartridge filters for both the Normal Operation Case and the Design Basis Case.
11.5.2.2 Components The SRS has five major subsystems:
(1) Spent resin processing system (2) Spent filter/ion exchange media processing system (3) Spent filter cartridge processing system (4) Mobile radwaste processing system (MRPS)
(5) Dry active waste processing system The function of each of these subsystems is described in the following paragraphs.
11.5-3 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE 11.5.2.2.1 Spent Resin Processing System The system for transferring spent resins from any of the ion exchangers to the spent resin storage tanks (SRSTs) consists of four separate headers connected to four eductors and discharge systems that permit the transfer of resin from any of the 30 ion exchanger units to either of two SRSTs. Pressurized air is used to transfer resin from either SRST to the loadout station (LS) to which the MRPS container is connected.
Pressurized air can also be used to transfer resin from one SRST to the other.
Two SRST eductors are provided to transfer resin from one SRST to the other.
Figure 11.5-3 is a flow diagram of the spent resin processing system.
The general layout of the system is shown in Figure 11.5-11. The SRSTs are located in shielded cells. All of the valves, instruments, and the discharge eductor are located in a separately shielded area (valve gallery) adjacent to the SRST cells. The spent resin LS is located on the east outside wall of the auxiliary building.
A spent resin sampling system allows for the collection of grab samples as resins enter the SRSTs or while the spent resins are being transferred out of the SRSTs to the MRPS.
All of the equipment associated with this system is considered potentially highly radioactive. None of the equipment, which is located behind shielding, will be approached either for operation or maintenance except under the direction of plant radiation protection personnel under the special work permit rules of the plant.
11.5.2.2.2 Spent Filter/Ion Exchange Media Processing System Pressurized air is used to transfer exhausted media from either of the two radwaste media filters to the LS to which the MRPS container is connected.
11.5.2.2.3 Spent Filter Cartridge Processing System This system is designed to remove and handle spent filter cartridges generated in the CVCS, spent fuel storage system, and LRS. The radioactively contaminated spent filter cartridges can be removed from the filter housing or vessels with the operator remaining behind shielding. The spent cartridges are transferred to storage or to the MRPS in shielded transfer casks. Transfer casks are provided to move underwater vacuum filters from the SFP to the MRPS.
It is assumed that the whole change-out procedure takes one hour. This includes loading clean filter cartridges. Half an hour can be spent with the operator protected from radioactive spent cartridges by the transfer cask. For the remaining time, the operator is protected from the filter cartridges by concrete, steel, and/or lead shields.
Figures 11.5-6 through 11.5-8 show the location of filters in the system.
11.5-4 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE Figure 11.5-9 illustrates the system for capturing the filters using the grappling hook, cask, pulley, and mirrors. Figure 11.5-10 shows the cover of the filter vessel.
11.5.2.2.4 Mobile Radwaste Processing System The MRPS is a skid-mounted mobile radwaste dewatering/solidification system. The MRPS for media and resin is located on a concrete pad as shown in Figure 11.5-12 and in Bay 2 of the SRSF for filters. This space will accommodate the spillage of resins via concrete sloped to a drain within the area.
The MRPS is operated on a batch basis to solidify concentrates, to dewater or solidify spent ion exchange or filtration media, and to encapsulate spent cartridge filters.
Slurries from the media filter vessels are sluiced out to the MRPS and dewatered or solidified. Spent resin slurries are sluiced to the MRPS (refer to Section 11.5.2.5) from the SRST and dewatered or solidified. Filter cartridges are transferred to the MRPS container in a shielded spent filter transfer cask, if required. Waste concentrates, ion exchange media, filtration media, and cartridge filters are dewatered or solidified in accordance with the process control program detailed in the Plant Procedures Manual.
Normally, containers are dewatered or solidified in processing shields. The containers are stored in the shields until shipment. The containers are transferred by mobile cranes into the shipping casks. Containers may be dewatered and/or solidified while in casks on the trailers by which they will be shipped. When processing is finished in shipping casks, the containers are shipped immediately so that no in-plant handling is required.
Complete waste solidification or absence of free liquid prior to shipment is ensured by the implementation of a process control program consistent with the recommendations of NUREG-0472, March 1979 (Reference 1). For medium and high activity waste, level sensors monitor the levels in the waste containers and provide alarm signals to alert the MRPS operator to take action to prevent filling beyond preset levels. Low activity waste level may be monitored by sight by the MRPS operator. Potential waste container overflows are contained by the curbed processing pad, then flow into a sump that will return the spill to the radwaste system.
11.5.2.2.5 Dry Active Waste Processing System Potentially radioactive dry wastes are collected at appropriate locations throughout the plant, as dictated by the volume of the wastes generated during operation or maintenance. The wastes are then segregated, processed, and packaged.
Compressible dry active wastes may be processed by compaction in either a drum or box compactor. During compaction, the airflow in the vicinity of the compactor is directed by the compactor exhaust fan through a HEPA filter before it is discharged.
Large or highly radioactive components and equipment that have been contaminated during reactor operation and that are not amenable to compaction are handled either by 11.5-5 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE qualified plant personnel or by outside contractors specializing in radioactive materials handling, and the components and equipment are packaged in shipping containers of an appropriate size and design.
11.5.2.3 Mixed Waste Mixed waste is liquid or solid waste that is both hazardous and radioactive. Mixed waste is segregated and accumulated in drums in Bay 6 of the SRSF. Filled drums of mixed waste are placed in storage in Bay 5 of the SRSF.
11.5.2.4 Component Failures and System Malfunctions Analyses have been performed to evaluate potential dose to operating personnel should the SRSs malfunction or components fail. The components and systems considered most likely to fail are discussed below.
During the transfer of spent resin to the SRSTs, a failure of the motive water pump could result in lines becoming clogged with resin. The lines may be cleaned out by starting up the second motive water pump and using the normal operating procedure.
The CVCS resin transfer piping system includes cleanout flanges, which can be used if the lines cannot be cleaned by using the normal procedure. The cleanout flanges are located in areas that are shielded from the main resin transfer lines, and minimize the dose to operating personnel during a cleanout operation.
During the transfer of spent resin from a demineralizer to an SRST, failure of a pneumatically operated valve on the outlet of the demineralizer would require special operator action. The valves have reach-rods extending through the shield wall, permitting manual operation of the valve. After flushing the demineralizer completely and allowing sufficient time for decay of any residual activity, the operating personnel would perform the required repair on the valve. A maximum dose of 800 mR is estimated to occur in the repair of a valve on a CVCS mixed bed demineralizer.
As a backup in the event the pneumatically operated tank outlet valve fails during transfer of spent resin from one of the SRSTs, the valve can be controlled by manual operators extending through a second shield wall to the operating area.
11.5.2.5 Packaging Disposable mild steel liners are used for packaging dewatered, solidified, or encapsulated wastes. The typical liner sizes may range from 80 to 300 cubic feet. High
-integrity containers (HICs) are also used for packaging dewatered or encapsulated wastes. Typical HIC sizes range from 75 to 200 cubic feet. Wet solid waste may be packaged for further offsite treatment, onsite storage, or offsite disposal.
Dry active wastes may be packaged for further offsite treatment, onsite storage, or offsite disposal. For onsite storage, 55-gallon steel drums, 4 x 4 x 6 foot steel boxes, or 11.5-6 Revision 27 May 2023
DCPP UNITS 1 & 2 FSAR UPDATE bags are typically used. Drums, boxes, and intermodal containers classified as Industrial Package Type 1 or Type 2 containers are utilized for transportation offsite, as applicable.
11.5.2.6 Storage Facilities Onsite storage for packaged wastes is provided by the SRSF and the RSB. These buildings are located east of the auxiliary building, as shown in Figure 11.5-4.
Unpackaged activated metals and underwater vacuum cleaner filters are stored in the spent fuel pools. Disused radiation monitors may also be stored in the new fuel storage vaults.
The SRSF provides a storage area for metal boxes, drums, and shielded filters. The SRSF can hold 580 drums or a combination of 65 boxes and 60 drums. The arrangement of the rooms in the SRSF is shown in Figure 11.5-5. A forklift is used for moving the containers into and within the storage area. Concrete walls provide shielding between the various vaults in the SRSF. Encapsulation or dewatering of filters may occur in the SRSF. Segregation and compaction of dry active waste is also performed in the SRSF.
The RSB provides storage areas for 180 liners or HICs and for compacted dry active waste in 4 x 4 x 6 foot boxes or 55-gallon drums. The liner storage vaults are sized to accommodate 80 ft3 containers stacked 3 wide by 2 high.
An overhead crane assembly is used for moving liners or HICs to their respective storage areas in the RSB. A shielded cask rail car is used to transport liners or HICs from the load-out area to the storage vaults. Encapsulation of filters and dewatering of resin may occur in the shielded cask rail car in the RSB truck bay. A liner-inspection/decontamination station is also provided for preparing containers for storage or shipping.
The compacted dry active waste storage area (DAW vault) is sized to accommodate 522 boxes at 93 ft3 each, totaling 48,546 ft3 of storage. Drums can also be stored in this facility. A forklift is used for moving the containers into and within the DAW vault.
The SGs and reactor vessel head assemblies (RVHAs) were removed from DCPP Unit 1 and Unit 2 during the SG and RVH replacement projects. These ten large components are temporarily stored in the steam generator storage facility (SGSF) specifically constructed for this purpose. The SGSF meets the radwaste storage requirements for temporary storage of the SGs and RVHAs until site decommissioning.
The SGSF is designed to be used as a non-occupied mausoleum for the temporary storage of the SGs and RVHAs. No other radwaste storage is permitted within this facility.

The program identifies changes in the use of unrestricted areas (e.g., for agricultural purposes) to permit modifications in monitoring programs for evaluating doses to individuals from principal pathways of exposure.
11.6.2 PROGRAM DESCRIPTION 11.6.2.1 Expected Background HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
The 1984 results of the pre-operational monitoring program are shown in Table 11.6-4 and Reference 1. Table 11.6-4 summarizes measurements of external dose with thermoluminescent dosimeters (TLDs), gross beta, gamma isotopic, and I-131 activities in air samples and gamma isotopic and I-131 and/or tritium activities (as appropriate for particular samples) in marine and terrestrial samples. There were no known local man-made sources of radioactivity in the vicinity of DCPP; therefore, the variations shown in these tables are considered to be either natural variations or fallout from weapons testing. Gamma isotopic analyses were made of all marine and terrestrial samples. Only a few showed measurable activities above background. The results of all samples with detected activity during the pre-operational period of January 1, 1981, through March 31, 1984, are included in the Pre-operational Environmental Report (Reference 8).
The data, presented on an annual basis in the Annual Radiological Environmental Operating Report, show local differences in activity as well as seasonal variations.
11.6-1 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE Terrestrial variations may be attributable to such factors as variation in the spatial distribution of radionuclides in the soil, the amount of rainfall, TLD locations in valleys as contrasted to hillsides, and secondary sources of airborne dust from such activities as construction or farming.
These data and those for previous years serve as a baseline during plant operation.
11.6.2.2 Critical Pathways HISTORICAL INFORMATION IN ITALICS BELOW NOT REQUIRED TO BE REVISED.
Based on the expected radiological releases from Unit 1 and Unit 2 (refer to Sections 11.2 and 11.3), and the tabulated estimates of dose, none of the releases were expected to significantly increase the total dose to man relative to natural background.
Calculations showed which principal pathways for atmospheric releases will give the maximum doses. All doses through aquatic releases were expected to be negligible.
The levels of radiation in environmental samples were expected to be very low and, for many isotopes, below the minimum detectable level, using the best techniques available at original plant licensing. For this reason, dose analyses are performed based principally on plant effluent data, with secondary analyses based on environmental data.
For airborne releases, the ODCM is used with measured local meteorological data, measured release data of the gases and particulates, plus local demographic data, to estimate individual dose.
From the gamma dosimeter stations for the direct radiation measurements, in general, the offsite stations are used to serve as reference points for natural background and manmade environmental radiation that is not associated with plant operations. Onsite and fenceline stations are used to measure dose from the plant. Therefore, direct radiation dose above background is obtained and compared to calculated doses.
For radiological releases to the ocean, the ODCM is used in conjunction with effluent data to estimate dose from the consumption of aquatic foods grown within the radiological influence of the plant.
Bioaccumulation factors for species in the vicinity of Diablo Cove are obtained from Regulatory Guide 1.109, Revision 1 (Reference 7).
Aquatic food intake is based on the parameters provided in Reference 7 via the ODCM.
Consideration is also given to any group that has unusually high per capita consumption.
11.6-2 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE 11.6.2.3 Sampling Media, Location and Frequency 11.6.2.3.1 Marine Samples The types of marine samples, the frequency of collection, and the sampling locations are presented in the ODCM. These samples were selected to represent various food products.
11.6.2.3.2 Terrestrial Samples Possible dose to man could result from atmospheric immersion and inhalation, and consumption of radionuclides deposited as particulates from the gaseous effluent of DCPP. To monitor the above pathways, various types of terrestrial samples are collected and analyzed. Air samples using particulate filters and iodine cartridges are taken continuously at a minimum of four sample locations. The sites were selected to provide data at downwind locations, major population centers, and areas that are not influenced by plant operations. It should be noted that eight of 16 sectors surrounding DCPP are located over water; therefore the five air sampling stations recommended by the Branch Technical Position for Radiological Environmental Monitoring Program (Revision 1, 1979) were reduced to four air sampling stations.
Gamma dosimetry measurements are made at environmental monitoring stations using TLDs. The TLDs were selected because of their sensitivity and the ease of readout.
Drinking water samples are collected from the domestic water system. Surface water samples are collected from the plant outfall.
Samples of various foodstuffs produced in the area are also collected when available.
The terrestrial sampling frequency reflects the areas that are most sensitive to changes in radioactive levels and in dose measurements. Thus, the airborne sampling is weekly, the TLD measurements are quarterly, and the terrestrial foods measurements are monthly, quarterly, or in season.
11.6.2.4 Analytical Sensitivity 11.6.2.4.1 Types of Analyses The types of radiological analyses performed on each sample are presented in the ODCM. The offsite radiological monitoring program emphasizes analyses for those radionuclides expected to be present in the DCPP effluent and those that will be the major contributors to dose to the public.
The effluent from DCPP is expected to contain radionuclides whose identity and activity can be determined by gamma spectrometry. Thus, all samples are placed in a fixed 11.6-3 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE geometry and analyzed by gamma spectrometry. Other analysis techniques can be utilized as deemed necessary.
11.6.2.4.2 Measuring Equipment The equipment presently in use for the radiological monitoring program typically includes, but is not limited to:
(1) Gas-flow proportional counter for gross beta analyses (2) High purity intrinsic germanium detectors (or equivalent)
(3) TLDs for external dose measurements (4) Beta-gamma coincidence spectrometer (5) Liquid scintillation spectrometer 11.6.2.4.3 Sample Detection Sensitivity The ability to accurately determine the radioactivity in a sample is a function of many variables including the following: (a) sample size, (b) self-absorption in the sample, (c) detector counting efficiency, (d) counting time background count rate, (e) half-life of the isotope, (f) loss of radionuclides in sample preparation, and (g) ability to distinguish between isotopes with similar gamma emission energies. Consistent results are obtained by standardizing procedures that maintain as many of the above variables constant as practicable.
11.6.2.5 Data Analysis and Presentation The data acquired from the environmental monitoring program falls into the categories of:
(1) Information on the distribution of radioactivity in lower trophic levels in the physical environs of DCPP (2) Information on external radiation in the vicinity of DCPP (3) Information on radionuclides in foodstuffs that may result in a dose to man In examining the distribution of radionuclides in the environment and lower trophic levels, comparisons are made to the preoperational data to determine if there are any biological or physical compartments in nature that are accumulating radioactivity.
Similarly, external radioactivity measurements during plant operation are compared with the average and range of data obtained in the preoperational program.
11.6-4 Revision 24 September 2018
DCPP UNITS 1 & 2 FSAR UPDATE If radionuclides due to plant effluents are found in foodstuffs, estimates of radiation dose are made that utilize the best estimates of food consumption. These dose calculations are compared with those based on plant emission data with the appropriate meteorological and aquatic dispersion models as discussed in Section 11.6.2.2.
The data from the offsite radiological monitoring program are reported in the Annual Radiological Environmental Operating Report. The report includes the basic data on sampling locations, organisms collected, counting data, gross activity levels, identification of gamma emitting isotopes, and the associated counting errors. Tables 11.6-13 and 11.6-14 present estimated concentrations and depositions based on the monitoring program.
11.6.2.6 Program Statistical Sensitivity The activity in environmental samples is low after dilution and dispersion of radionuclides released by the power plant. For many isotopes, the radioactivity is below the lower limits of detection (LLD) that are listed in Table 11.6-11. With dose estimated from effluent data as shown in Sections 11.2 and 11.3, much lower dose levels can be estimated even though large errors may be introduced in the dispersion modeling.
Thus, doses estimated using effluent data provide a more detailed definition of the dose increments due to the operation of DCPP than dose estimates calculated from the environmental measurements.
Counting errors for effluent data and errors associated with the calculational models are used to determine the overall sensitivity of estimated dose.
11.6.3 SAFETY EVALUATION 11.6.3.1 10 CFR Part 50, Appendix I - Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion "As Low as is Reasonably Achievable" for Radioactive Material in Light-Water-Cooled Nuclear Power Reactor Effluents The ODCM provides data on measurable levels of radiation and radioactive materials in the environment. The data are reported in the Annual Radiological Environmental Operating Report.
Annual land use censuses are conducted in the vicinity of DCPP, and reported in the Annual Radiological Environmental Operating Report, in order to provide compliance with 10 CFR 50 Part Appendix I,Section IV(B)(3).

Table Notation The LLD is defined, for purposes of these specifications, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95 percent probability with only 5 percent probability of falsely concluding that a blank observation represents a "real" signal.
Revision 12 September 1998
DCPP UNITS 1 & 2 FSAR UPDATE TABLE 11.6-11 Sheet 2 of 2 For a particular measurement system (which may include radiochemical separation):
4.66 S b
LLD EV2.2 2Yexp( t) where:
LLD is "a priori" the lower limit of detection as defined above (as pCi per unit mass or volume)
Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)
E is the counting efficiency (as counts per transformation)
V is the sample size (in units of mass or volume) 2.22 is the number of transformations per minute per picocurie Y is the fractional radiochemical yield (when applicable) is the radioactive decay constant for the particular radionuclide t is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of Sb used in the calculation of the LLD for a detection system will be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background will include the typical contributions of other radionuclides normally present in the samples (e.g., potassium-40 in milk samples).
Analyses will be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally, background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Environmental Radiological Operating Report.
