SUMMARY
This report summarizes radiological effluent released from the Fort St. Vrain Nuclear Station for the period of January through December, 1993 consistent with 10 CFR 50.36a. This information is provided pursuant to the requirements of Sections 5.5.2 of the Fort St. Vrain Decommissioning Technical Specifications (DTS).
This report uses the reporting format recommended by Regulatory 4 Guide 1.21 where appropriate.
The following tables with a supplemental information section are l' included with this report i
Table Descriotion ,
i 1A Gaseous Effluents - Summation of All Releases i 1C Gaseous Effluents - Ground-Level Releases l 2A Liquid Effluents - Summation of All Releases 2B Liquid Effluents . Batch and Continuous '
3 Solid Waste and Irradiated Fuel Shipments 4A Hourly Meteorological Data Please note that Table IB (of Regulatory . Guide 1.21) has been omitted from this report because all of our gaseous effluents are assumed to be ground-level releases as opposed to being elevated releases.
The Fort St. Vrain Decommissioning Technical Specifications and Offsite Dose Calculation Manual (ODCM) requirements apply to~the following radionuclides: H-3, Mn-54, Co-60, Zn-65, Cs-134, Cs-137, and Ce-144. This list does not mean that only these nuclides are considered. Other gamma emitting nuclides that are identifiable, together with the above nuclides, are analyzed and included in this report.
Sample activities that are less than the detection limits are listed as "none detected" and no value is entered into the calculations of the total activities. This results in the reporting of values which are representative'of the total curies released.
2
The lower limit of detection (LLD), for the purposes of this report, is defined as the smallest concentration of radioactive material in a sample that will yield a net count above the system background, that will be detected with a 95% probability of being correct and only a 5% probability of falsely concluding that a blank observation represents a real signal. The LLD values specified in the ODCM are as follows:
Liauld Principal Gamma Emitters 5.00E-07 pCi/ml Tritium 1.00E-05 pCi/ml Gaseous Principal Gamma Emitters 1.00E-11 pCi/cc (Particulate)
Tritium (Gas) 1.00E-06 pCi/cc All samples were analyzed to the LLD concentration limits for nuclides specifically listed in our ODCM, however, those which had values of less than LLD were marked as "none detected". The "none detected" values were not included in the total values for the pathway.
With respect to the total volume of water used for dilution of l radioactive liquid effluent, all average diluted concentrations are _!
based on the activity at the unrestricted area. Although this I effluent could eventually reach one of two rivers (St. Vrain Creek '
and South Platte River) which converge approximately one and one-half miles downstream of the plant, no further dilutions were assumed. Additional discussion on river flow is contained in Section 4d of the Supplemental Information Section.
There were no abnormal or unplanned radioactive gaseous or liquid waste releases made during this reporting period.
Table 3 summarizes the radioactive solid waste shipments made during 1993. Since the table states "....for burial or disposal" we have identified only those shipments made to a burial site. The summary includes shipments performed by processors and agents in addition to those made directly by the station during 1993.
Materials which were shipped to a processor for volume reduction in 1993 are not included in this report.

l There have been 2 major design changes to the radioactive waste j systems reviewed by the Decommissioning Safety Review Committee l (DSRC) during the period covered by this report. In accordance )
with decommissioning procedure DPP 4.1.1, Design / Design Document j Control, changes to components / systems addressed by the DTS or by l the Off-site Dose Calculation Manual are considered upgraded design and hence must be performed by an Engineering Change Request (ECR) .
- 1. The radioactive gaseous waste hold-up system (System 63) was not required to remain in service and decommissioning by removal or decontamination methods was initiated in March, 1993. PSC does not anticipate that there will be'a need to make batch releases of radioactive gaseous effluent through the remainder of the decommissioning process. All radioactive gaseous waste currently generated as a result of 4 decommissioning activities originates from the PCRV Shield Water System and is directed on a continuous basis to the existing Reactor Building ventilation exhaust HEPA filter system for subsequent release to the environs. This gaseous effluent stream is sampled weekly and analyzed for tritium and gamma isotopes.
- 2. ECR 93-03 authorized the tie-in of the Airborne contamination Control System (ACCS) for the decommissioning rotary work platform to the Reactor Building ventilation exhaust system.
The installation of the ACCS ducting and filters was performed by Westinghouse Team (WT) package 2.3.2.9A. This modification allowed either exhaust system train (F-7301 or F-7302) to take suction directly from the Reactor Building (existing) and/or the ACCS. See the attached ECR copy.
ECR 93-33 authorized the temporary installation of commercial grade I HEPA filters in F-7301, F-7302, and F-7302S (following DOP testing) until the requirements of DTS 3.2 became applicable; these have since been replaced with nuclear grade HEPA filters. See the attached ECR copy.
Issue 4 of the Decommissioning Offsite Dose Calculation Manual l (DPP-5.4.2 attached to this report), was reviewed by the .
Decommissioning Safety Review Committee (DSRC) on December 8, 1993 )
and became effective December 13, 1993. The ODCM was revised during the report period to provide site specific dose conversion factors for additional radionuclides beyond those covered in the initial issue, simplify the process for determining alarm setpoints prior to liquid effluent releases, delete requirements for the j gaseous waste hold-up system which is no longer in use and provide i clarification as appropriate. These revisions maintained the :
required levels of radioactive effluent control and did not ]
adversely impact the accuracy or reliability of effluent, dose, or I setpoint calculations. !

4 l I
The Decommissioning Process Control Program administrative procedure, FSV-RW-PCP-A-100, Process Control Program was reviewed by the DSRC and revised to add Section 5.6.2 which discusses shipment and disposal of resins and filter media containing a total activity of less than 1.0 microcurie per cubic centimeter for nuclides with half lives greater than 5 years. Section 5.6.3 was also added which describes the PCRV Shield Water System.
There were no liquid effluent activity monitors or their associated -
recorders inoperable for more than thirty days during this reporting period.
Radiation doses resulting from the release of radioactive liquid and gaseous effluents from Fort St. Vrain during this period are '
reported below. Radiation doses were calculated in accordance with the Fort St. Vrain Offsite Dose Calculation Manual which is based on NUREG-0472, " Radiological Effluent Technical Specifications for PWRs", NUREG-0133, " Preparation of Radiological Ef fluent Technical Specifications for Nuclear Power Plants", and other inputs from the NRC.
Doses were calculated for a " maximum exposed" individual present at all times of the year at the Emergency Planning Zone (EPZ), which was reduced from 590 meters to a minimum of 100 meters upon implementation of the DTS, and in the sector in which all of the activity was calculated to have been released. The following are the 1993 doses:
Liould - 10CFR50 Whole Body 9.80E-05 mrem Maximum Exposed Organ 5.68E-03 mrem Gaseous - 10CFR50 Noble Gas Gamma 0.00 mrem Noble Gas Beta 0.00 mrem Iodine, Particulates, Tritium 1 l

Infant Whole Body 8.25E-02 mrem Organ (maximum) 8.25E-02 mrem Done 0.00 mrem Gaseous - 10CFR20 Iodine, Particulates, Tritium 8.38E-02 mrem All doses arc within the limits of 10CFR20 and 10CFR50.
The doses demonstrate conformance with the exposure. limit in 40CFR190 of 25 mrem to the total body, 75 mrem to the thyroid, and 25 mrom to any organ.
To show conformance with 40CFR190 subpart B, the total curies of krypton released from Fort St. Vrain was 0.00 Ci. The 29.78 kev iodine-129 peak is below the minimum detectable encrgy of.our detectors. However, waste streams are regularly analyzed specifically for iodine-129 for compliance with 10CFR61. The results of these analyses have been less than the LLD. The reactor has been shutdown since August, 1989. Any iodine-131 which was produced by the fission process has undergone in excess of 100 half-lives decay. It is assumed the release.of iodine-131 to the environment would be impossible, therefore, iodine-131 analysis has been discontinued in accordance with the decommissioning ODCM.
An annual land use census was performed as part of the Fort St.
Vrain Radiological Environmental Monitoring Program. . Changes made to environmental sampling locations as a result of the land use census are reported in the Annual Radiological Environmental Monitoring Program Report (Annual Radiological Environmental )
Operating Report).

- 1. Reaulatory Limits All results of radioactivity analyses of gaseous and liquid effluent are used in accordance with the methodology and parameters listed in the Offsite Dose calculation Manual (DPP-5.4.2) to assure that the concentrations at the point of release are maintained within the regulatory limits contained in the Offsite Dose calculation Manual (ODCM). These limits ensure the quantity of radioactive effluent released from the plant is maintained as low as reasonably achievable, and in any event, within the limits of 10CFR20 and in accordance with 10CFR50.
The dose to a member of the public due to I-131, tritium, and radioactive particulates with half-lives longer than eight days in gaseous effluents will be limited to:
a) 7.5 millirems to any organ during any calendar quarter, and, b) 15 millirems to any organ during any calendar year.
The dose or dose commitment to a member of the public from radioactive materials in liquid effluents released to unrestricted areas is limited as follows:
a) During any calendar quarter to less than or equal to 1.5 millirems to the total body and to less than.
or equal to 5 millirems to any organ, and, b) During any calendar year to less than or equal-to 3 millirems to the total body and to less than or equal to 10 millirems to any organ.

- 2. Maximum Permissible Concentrations (MPC's)
All'MPC's used in determining allowable release rates from the gas and liquid waste systems were those listed in Table II, Columns 1 and 2 respectively, of Appendix B to 10CFR20.
- 3. Averace Enerav The average energy (E-Bar) of the radionuclide mixture in -
releases of fission and activation gases was not calculated or used at this facility.
- 4. Measurements and Annroximations of Total Radioactivity a) Fission and Activation Gases A continuous release is being made from the PCRV via the ACCS and Reactor Building ventilation exhaust systems.
This release methodology is acceptable because of the low activity level of gas within the PCRV.
Batch releases of radioactive gaseous waste were discontinued after March, 1993, when the gaseous waste hold up system was taken out of service.
All radioactive gases were released to the Reactor Building exhaust ventilation system which has a flow' rate of approximately 20,000 cubic feet per minute. The full-flow of this exhaust was directed through high efficiency particulate filters (HEPA) prior to the release to the environment.
Downstream of the HEPA filters, the gas stream radioactivity was sampled and analyzed on a weekly basis.
b) Iodines The reactor was shut down permanently in August,1989 and the fuel removed completely in May of 1992 resulting in the elimination of the iodine source term. Therefore, iodine-131 analysis'has been discontinued in-accordance with the decommissioning ODCM.
c) Particulates A 2-inch particulate filter was removed and analyzed each week. Gross beta analysis, as well as gamma spectral analyses, was performed to identify and quantify any_
radionuclides. The quantity of any radionuclides on this filter with half-lives greater than eight days was similarly correlated to total flow during the collection period.
8
d) Liauid Effluents All liquid effluent discharged from the site reached the unrestricted area at the Goosequill Ditch. From that point, the effluent can be diverted to the St. Vrain Creek via the St. Vrain Slough or, more commonly, diverted to the Farm Pond which is approximately one mile north of the plant site. Outfall from the Farm Pond reaches the South Platte River. Both rivers converge approximately 1-1/2 miles from the plant site. The average stream flow reported in section 5a of this supplemental report is a summation of both rivers, and was received and tabulated from data provided by the Colorado Department of Natural Resources in Greeley, Colorado.
Liquid effluent was released from the site using a batch node from the Reactor Building Sump and the radioactive liquid waste system. The Reactor Building Sump area can hold several hundred thousand gallons of waste water from various sources which could be contaminated.- The liquid i waste system consists of two 2000 gallon receivers,'one 2000 gallon monitoring tank, and associated filters and demineralizers. This system was designed to collect and process contaminated waste water resulting from reactor and laboratory operations. l A sample of the tank or sump contents was taken and analyzed prior to each release. These analyses include-gross beta, gross alpha, tritium, and gamma spectroscopy. ,
The results of these analyses, and other analyses as '
dictated by the gross beta results, were used to !
determine the maximum release rate from the site. The ;
liquid effluent was diluted with cooling tower blowdown j which runs at or more than 1100 gallons per minute. The !
resulting mixture was sampled during.the release period !
to confirm compliance with regulatory limits.
The liquid effluent from the batch release mode was l monitored continuously by a gamma activity monitor. ;
All tank level indicating devices, flow monitoring and recording devices, and radiation monitoring equipment were calibrated and maintained at scheduled intervals in accordance with established procedures.
9
b e) Overall Errors The overall error associated with determining the total activity released from the site for both gaseous and liquid effluent is estimated to be 17.3 percent. This value is the square root of the sum of ' squares of counting statistics and associated calibration errors, ~
sampling errors, and tank volume- estimates, each considered to be plus or minus 10 percent.

DPP 5.4.2 ISSUE 4 FORT ST. VRAIN NUCLEAR GENERATING STATION pago 3 of 64 0 PublicSOTVICO' PUBUC SERVICE COMPANY OF COLORADO 1.0 PURPOSE 1.1 The Offsite Dose Calculation Manual (ODCM) is a supporting document of the Fort St. Vrain Nuclear Station Decommissioning Technical Specifications. The ODCM describes the methodology and parameters to be used in calculation of offsite doses due to radioactive gaseous and liquid effluents. This document also describes the methodology used for calculation of the liquid and gaseous effluent monitoring instrumentation alarm / trip setpoints. Liquid and gaseous radioactive waste treatment system configurations are described in the Decommissioning Plan (Ref. 4.1).
1.2 This ODCM provides the information and methodologies to be used by Fort St. Vrain (FSV) to assure compliance ,
with 10CFR20, 10CFR50.36a, 10CFR50 Appendix A (GDC 60 &
64), 10CFR50 Appendix I, and 40CFR190 with respect to liquid and gaseous radiological effluents.
1.3 This ODCM is based on " Radiological Effluent Technical Specifications for PWR's (NUREG-0472, Draft)," and .
follows the methodology and models suggested by NUREG-0133, " Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," and other inputs from the Nuclear Regulatory Commission (NRC).
Regulatory Guide 1.109 is used for guidance and ICRP-30 dose conversion factors are used for dose calculations.
1.4 This ODCM is maintained at Fort St. Vrain for use as a reference guide and training document of accepted methodologies and calculations. Changes in the calculation methods or parameters will be incorporated to ensure this ODCM represents the present methodology in all applicable areas. Changes to this ODCM will be reviewed and approved in accordance with Section 5.10, Fort St. Vrain Decommissioning Technical Specifications.
1.5 Also included in this manual is a description of the FSV Radiological Environmental Monitoring Program (REMP) in Attachment F. This designates specific sample types and locations currently used to comply with FSV Decommissioning Technical Specification requirements for the REMP. They are subject to change based on the results of the annual land use census.

DPP 5.4.2 Public FORT ST. VRAIN NUCLEAR GENERATING STATION Pago 64 O SerVICO* PUBLIC SERVICE COMPANY OF COLORADO 2.0 APPLICABILITY This procedure is applicable to all routine, planned liquid and gaseous effluent releases made pursuant to the FSV Decommissioning Technical Specifications and unplanned liquid and gaseous effluent releases.
3.0 GENERAL 3.1 The Radiation Protection Manager (RPM) shall be responsible to assure that the ODCM is utilized in accordance with the FSV Decommissioning Technical Specifications. The RPM is also responsible for ensuring that all radioactive waste is handled, stored, ~
and disposed of in accordance with NRC requirements and FSV procedures. ,
3.2 All radioactive liquid waste is discharged via a common line, is monitored by a liquid waste activity monitor, and therefore, there are no multiple release points and monitor settings do not have to be reduced to account for multiple releases. .
3.3 Liquid effluent monitor alarm setpoints are determined in order to assure compliance with 10CFR20. The setpoints ensure that the concentration of radionuclides in the liquid effluent at the site boundary (unrestricted area) does not exceed the concentrations specified in 10CFR20, Appendix B.
3.4 If the calculated alarm setpoint for any of the FSV radiation monitors exceeds the range of the instrument, appropriate lower setpoints will be determined by the RPM. In all cases, since the setpoint is reduced, compliance with the limits in this procedure will be assured.
3.5 The alarm setpoints as calculated in this procedure are the maximum allowable; setpoints may be set lower than the calculated values if so desired.
3.6 Surveillance requirements must be completed within +25%
of the specified frequency. Should this frequency be exceeded, the applicable instrument shall be declared inoperable until such time that the required test or calibration is successfully performed.

DPP 5.4.2 Public FORT ST. VRAIN NUCLEAR GENERATING STATION Page 64 SerVlCO* PUBLIC SERVICE COMPANY OF COLORADO 3.7 The appropriate portions of the liquid and gaseous effluent treatment systems shall be used to reduce releases of radioactivity when the projected doses in a 31-day period would exceed 2 percent of the guidelines for the annual dose or dose commitment conforming to Appendix I to 10 CFR Part 50.
3.8 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% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.
3.9 For a particular measurement system which may include radiochemical separation: ,
LLD= 2.71+4.66/3 T E V 2. 22 E6*Y'exp ( ~kh t)
Where: .
LLD is the "a priori" lower limit of detection as defined above as microcuries per unit mass or volume,
%dB is the standard deviation of the total background counts or of the total counts of a blank sample, as appropriate, as counts, T is the count time of background in minutes, E is the counting efficiency as counts per disintegration or counts per gamma for gamma spectroscopy, V is the sample size in units of mass or volume, 2.22E6 is the number of disintegrations per minute per microcurie, (dpm/pC1),
Y is the fractional radiochemical yield when applicable and/or the gammas per disintegration when applied to gamma spectroscopy, FOAM 10) 372 22 - X43
DPP 5.4.2 Public FORT ST, VRAIN NUCLEAR GENERATING STATION pggg g ServlCO* PUBLIC SERVICE CortlPANY OF COLORADO A is, if radioactive decay correction is l applicable, the radioactive decay constant for the particular radionuclide, At is the elapsed time between the sample collection and time of counting. I 3.10 Valueu of E, V, Y, and At, which are appropriate to the sample, should be used in the calculation.
3.11 It should be recognized that the LLD is defined as an a oriori (before the fact) limit representing the capability of a measurement system and not as an a costeriori (after the fact) limit for a particular measurement.

This Special Report is to include an analysis which demonstrates that radiation exposures to all real individuals from all uranium fuel cycle sources (including all liquid and gaseous effluent pathways and direct radiation) are less than the standards in 40CFR190, Environmental Radiation Protection Standards for Nuclear Power Operations. If analysis i indicates that releases resulting in doses that exceed the 40CFR190 Standard may have occurred, then a variance from the Commission to permit such releases will be requested or, if possible, action will be taken to reduce subsequent releases.

6.14 EADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM 6.14.1 The Radiological Environmental Monitoring Program is conducted to provide data on levels of radiation and radioactive material in the site environs. The program discriminates -
-between those changes in environmental radiation and radioactivity levels resulting from radioactivo releases from the Fort St.
Vrain Station and those' changes attributed to other sources such as-worldwide fallout from weapons testing. The program evaluates the relationship between quantities of; radioactive material released in liquid and gaseous effluents and resultant radiation' doses to individuals from principal pathways of exposure. The results of this program ~are used to verify the effectiseness_of inplant measures applied to control the release of~
radioactive materials.

Continuous operation of this program since March, 1969, has provided baseline data which will be utilized as control values for statistical analysis of the results of the decommissioning radiological surveillance program.
6.14.4 This ODCM specifies the requirements for the Radiological Environmental Monitoring Program which will continue to be the responsibility of Public Service Company of Colorado.
6.14.5 Additional monitoring in the vicinity of the facility may be conducted or coordinated by other organizations, notably the Colorado Department of Health.
6.14.6 The results of the radiological environmental.
monitoring are intended to supplement the results of the radiological effluent monitoring by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. Thus, the specified environmental monitoring program provides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures to individuals resulting from the station operation.
6.14.7 Sampling locations were selected on the basis of local meteorological conditions and airborne concentrations calculated from those conditions, proximity of the plant to residences and communities, and otrer considerations in accordance with ?able 6 " '. .

- PUBLIC SERVICE COMPANY OF COLORADO Page 42 of 64 ODCM BACKGROUND INFORMATION Radioactive Licuid and Gaseous Waste System Backaround
- 1. The radioactive liquid and gaseous waste treatment systems are designed to ensure compliance with 10 CFR 20 and 10 CFR 50, Appendix I.
- 2. The Radioactive Liquid Waste System, System 62, is designed to collect, treat, and permit sampling, analysis and monitoring of all potentially radioactive liquid wastes discharged from the reactor. plant, and is described in.
Section 2.3.3.10 of the Decommissioning Plan. Radioactive '
liquid waste is collected, monitored, and processed,'if necessary, by the radioactive liquid waste system before being discharged from-the plant. Effluent from the ,
radioactive liquid waste system is diluted in the cooling tower blowdown / bypass line. The activity in the cooling tower blowdown / bypass line is maintained below the maximum permissible concentration (MPC) specified in 10 CFR 20.
- 3. The Radioactive Gas Waste System, System 63,.(Decommissioned.
in mid-1993), was designed to collect, treat, and permit sampling, analysis, and monitoring of potenti~ ally radioactive gases discharged from the plant, and is-described in Section 2.3.3.11 of the Decommissioning Plan. All radioactive gases l currently being released are directed to the reactor building ventilation system,' filtered, and discharged atf high velocity at the top of the reactor building, about.180 ft. above grade. Average offsite radioactivity concentrations.are significantly less than the MPCs specified in 10 CFR 20.
- 4. Solid radioactive wastes may be processed onsite or sent offsite for volume reduction or other processing. These processing activities, as well as activities associated with the packaging, storing, and shipping of radioactive wastes, are described in Section 3.3 of the Decommissioning-Plan.

- 1. Liquid Effluent Activity and Flow Rate Monitors, RT-6212, RT-6213, FS-4101-1 Two redundant activity monitors, RT-6212 and RT-6213, are provided in the radioactive liquid waste discharge line, arranged in one-out-of-two logic. Upon detection of high concentrations of gross gamma activity, these activity monitors will automatically alarm, shutdown the Liquid Waste Transfer Pumps, shutdown the Reactor Building sump pumps, and shut the block valves in the liquid waste discharge line. A flow switch, FS-4101-1, is provided in the cooling tower bypass / blowdown line to automatically alarm, shutdown the Liquid Waste Transfer Pumps, shutdown the Reactor Building sump pumps, and shut the block valves in the liquid waste '
discharge line in the event of low cooling tower bypass /
blowdown flow conditions that would not provide sufficient dilution of radioactive liquid effluent.
- 2. Air Flow Measurement Ventilation system flow is measured at the outlet of the system. Above-normal flow rates are alarmed to ensure that allowable activity release rates are not exceeded.
- 3. Meteorological Instrumentation Two meteorological towers, one 60 meters high and the other 10 meters high, are installed approximately one-half mile north of the plant. This instrumentation is provided for determination of dispersion coefficients and to provide data for the annual effluent release report. The 60 meter tower is the primary tower and the 10 meter tower is a backup. The 60 meter tower provides information on wind speed and Wind direction at 58 meters and 10 meters elevation, temperature at the lower level, temperature difference between the upper and lower levels, dewpoint, and precipitation. The 10 meter tower provides information on wind speed, wind direction, temperature and dewpoint. Both towers supply data to a data logger. Additionally, the 60 meter tower supplies data to chart recorders located in the control room. Both towers also supply data to chart recorders located in a weather station, which is also approximately one-half mile north of the plant. There is a gas-driven electric generator for emergency electrical supply in the event of loss of power to the towers and weather station.

l ECR-93-003 Safety Evaluation Page 3.1 j Llackaround This Engineering Change Request (ECR) is specifically addressing the tie-in of the PCRV decommissioning rotary work platform (DRWP) air contamination control system (ACCS) to system 73. The details of the remainder of the ACCS are in the Westinghouse Team Work Specification Number 2.3.2.9, " Install and Remove PCRV Rotary Work Platform," Work Package Number 2.3.2.9A, " Airborne Contamination Control," and Reference 1.
The ACCS is designed for contamination control above the rotary work platform to enable workers to remove components from the PCRV.
The system assures there is a downward flow of clean air through the rotary work platform to prevent the spread of radioactive contamination onto the platform and into the reactor building.
Ev_aluation The only modification to the existing system 73 is the tie-in of the ACCS ducting using fasteners and the addition of two dampers upstream of the ACCS tie-in point with system 73. These dampers will . be used to isolate the remainder of system 73 when that particular fan is being used to take a suction on the DRWP with the ACCS lined up. The normal operation of the ACCS~is to use one reactor plant exhaust f an lined up to the DRWP and the remainder of system 73 isolated from the ACCS tie-in point.
Seismic design requirements are not required. The Decommissioning Plan Section 3.4.9, Natural Disasters, states, "The seismic qualification of the Reactor Building will be maintained during decommissioning. No other new cr existing systems or equipment are required to function during or following an earthquake." system 73 is not seismically qualified and the ACCS will have no effect on the seismic qualification of the reactor building.
Of the accidents analyzed in the DP Section 3.4, only a heavy load drop accident involving activated graphite assumes that the reactor plant exhaust system is in operation. During the installation of' the ACCS, only one of the three reactor plant exhaust trains will be isolated and a clearance placed on that train. This leaves-the other two trains to provide for filtration. During the . actual operation of the ACCS, one train will be used for the ACCS line up while one of the other two trains will normally be taking a suction a directly on the reactor building. Even if only one ventilation exhaust train is in operation (lined up to the ACCS or directly to the reactor building), as long as SRs 3.2.1, 3.2.2, and 3.2.3 have I been satisfactorily completed, the requirements of LC 3.2 will be j met and the consequences of a heavy load drop analyzed ' in DP i Section 3.4.5 will not increase.

ECR-93-003 Safety Evaluation Page 3.2 Ouestion 2 DP Section 2.3.3.8.2, General Arrangement of Work Area for Graphite Block Removal, states:
A ventilation system will be installed to provide control of airborne contamination, including tritium. Air will be drawn from the refueling floor to the Work Platform, down through the access openings in the platform, and ,
then exhausted to the Reactor Building Vent.tla tion (exhaust) System (System 73) for discharge. The discharges from the Reactor Building Ventilation System will bo monitored in accordance with the FSV Offsite Dcse calculation Manual (ODCM) (Ref. 11). The airflow from '
uncontaminated areas to contaminated areas through the Work Platform will minimize personnel exposure to airborne contamination.
The ventilation system will ensure a positive downward flow of air over the workers. Exhaust ducts under the work platform will carry air through a HEPA filter, then to the existing plant ventilation system.
The ACCS exhaust ducting, upstream of the system 73 tie-in, will contain a roughing filter and not a HEPA filter as stated in'the DP. This roughing filter will remove large particulate that may be in the ACCS ducting prior to entering-the system 73 ducting. The HEPA filters in system 73 will ultimately remove any radioactive particulate prior to the air being released offsite. The accident analyses for radiological. releases takes no credit for these HEPA filters in the ACCS.
1 Ouestion 3(M I
The installation of the ACCS will not prevent the' reactor plant exhaust system from mitigating the consequences of an accident. At l least one train will be available while activated graphite is !
I located in the reactor building. The operation of~ system-73 is essentially the same as without the ACCS installed, from an -l accident mitigation standpoint. If the only system 73 train .~in - j operation was taking a suction on the ACCS, the requirements of LC !
3.2 would be met and the consequences of a heavy load drop accident l involving activated graphite would not increase. ]
o.
ECR-93-003 Safety Evaluation Page 3.3 Therefore, the probability of occurrence or the consequences of an accident or malfunction of equipment important to decommissioning safety previously evaluated in the Decommissioning Plan has not been increased.
Question 3(B)
The only accident that relies upon system 73 for mitigation'is a heavy load drop involving activated graphite blocks. There will be no handling of activated graphite blocks during installation of the ACCS. The installation and operation of the'ACCS does not create any accidents. During installation there will be proper radiological precautions taken to minimize the spread of contamination that may be inside the system 73 ducting.
4 Therefore, the possibility of an accident or malfunction of a different type than any evaluated previously in the Decommissioning Plan has not been created.
Question 3(C)
The requirements of LC 3.2 will remain in effect. In addition, by adhering to the requirements of SRs 3.2.1, 3.2.2, and 3.2.3_the analysis in this ECR remains valid. All gaseous effluent released must be monitored and controlled by the ODCM program as stated in the Basis for LC 3.3.
Therefore, the margin of safety as defined in the basis for any Technical Specification or in the Decommissioning Plan has not been reduced.

ECR-93-003 Page 5 Design Inputs This Engineering Change Request (Ech) is specifically addressing the tie-in of the PCRV decommissioning rotary work platform (DRWP) air contamination control system (ACCS) .to system 73 and any associated potential effects to the downstream system. The details of the ACCS are in the Westinghouse Team Work Specification Number 2.3.2.9, " Install and Remove PCRV Rotary Work Platform," Work Package Number 2.3.2.9A, " Airborne Contamination Control," and Reference 1. System 73 is designated a " Upgraded Design Control" system in accordance with PSC Procedure DPP 4.1.1 and "Important to Decommissioning Quality" in accordance PSC Procedure DPM 2.1.
The ACCS is designed for contamination control above the rotary work platform to enable workers to remove components from the PCRV.
The system assures there is a downward air flow through the rotary' work plattorm to prevent the spread of radioactive contamination onto the platform and into the reactor building. There are two tool slots for PCRV component removal. The rotary work platform and the stationary platform have a seal provided and there is a seal between the stationary platform and the cut concrete wall of the PCRV.
The air under the platform is exhausted through three ducts in the stationary platform. This air flow is then diverted into a singular duct that is routed up the vertical side of the PCRV concrete cut. The air is then routed to above the PCRV to elevation 4879'. At this point the air is split into two parallel ducts and each is routed through a roughing filter that removes large particles. At the exit of the roughing filters, the system is then routed to existing reactor building ventilation exhaust ducting that is on the suction side of the C-7301 and C-7302, reactor plant exhaust fans 1A and 1B, respectively. This is to allow the use of either roughing filter in combination with either reactor plant exhaust fan. See Figure 1 for a schematic-of the ACCS.
The ACCS described above and depicted in Figure 1, will be installed via Westinghouse Team Work Specification' Number 2.3.2.9 and Work Package Number 2.3.2.9A. The only modification to the existing system 73 is the tie-in of the ACCS ducting using fasteners and the addition of two dampers upstream of the ACCS tie-in point with system 73. These dampers will be used to isolate the remainder of system 73 when that particular fan is being used.to take a suction on the DRWP and the ACCS is lined up. The normal operation of the ACCS is to use one reactor plant exhaust fan lined up to the DRWP and the remainder-of system 73 isolated from the ACCS tie-in point. One of the other two reactor building exhaust fans would normally be taking a suction directly from the reactor building.
ECR-93-003 Page 6 Decommissioning Plan (DP) Section 2.3.3.8.2, General Arrangement of Work Area for Graphite Block Removal (Reference 3), states:
A ventilation system will be installed to provide control of airborne contamination, including tritium. Air will be drawn from the refueling floor to the Work' Platform, down through the access openings in the platform, and then exhausted to the Reactor Building Ventilation (exhaust) System (System 73) for discharge. The discharges from the Reactor Building Ventilation System will be monitored in accordance with the FSV offsite Dose Calculation Manual (ODCM) (Ref. 11). The airflow from uncontaminated areas to contaminated areas through the Work Platform will minimize personnel exposure to airborne contamination.
The ventilation system 'will ensure a positive downward flow of air over the workers. Exhaust ducts under the work platform will carry air through a HEPA filter, then to the existing plant ventilation system.
The Decommissioning Technical Specifications, LC 3.2 states:
The Reactor Building ventilation exhaust system shall be OPERABLE with:
- a. Reactor Building internal pressure subatmospheric, and
- b. At least one of the three ventilation exhaust trains OPERABLE, with each train consisting of one exhaust fan (C-7301, C-7302, or C-7302S) and the HEPA filter section of the associated filter assembly (F-7301, F-7302, or F-7302S).
APPLICABILITY: Whenever ACTIVATED GRAPHITE BLOCKS have been removed from the PCRV shielding water and remain inside the Reactor Building.
Design calculations have been performed (Reference 2) that present the results of flow and stress analysis to assure compliance with the applicablo requirements of Functional Requirements for the Block Removal System, Section 5.0, Airborne Contamination Control-System (Reference 4) . Specifically, three design calculations were performed:
1
- 1. Rotatory Work Platform Slot Flow Analysis - This analysis was performed to determine if the existing system 73 fans were able to provide sufficient flow through the two DRWP tool slots (minimum of 100 fpm per slot). With a minimum of 17,100 cfm of air flow through the system 73 fan in use, the minimum
ECR-93-003 Page 7 air flow through the DRWP tool slots is 104 fpm per slot.
- 2. System Flow Analysis -
This analysis was performed to calculate the pressure drop through the ACCS, from the DRWP to the tie-in with existing system 73 ducting, and assure the ducting is adequate. With the system flow at 19,000 cfm, the pressure drop through the system is 2.4 inches of water.
- 3. DRWP Duct Structural Analysis - This' analysis was performed to assure the structural integrity of the ACCS ducting. Based on L the flows calculated in item 2 above, the maximum calculated l
stresses in the ducting are within allowable stresses for the ducting under live and dead load conditions.
Various preconditions and operational scenarios related to system 73 and the ACCS have been agreed to between PSC and the .
l Westinghouse Team and is documented in Reference 5. The applicable l portions of this agreement are contained in this ECR.

ECR-93-003 Page 8 Upgraded Design Control Analysis The description of the ACCS in DP Section 2.3.3.8.2 is incorporated into this design as evaluated in the Safety Evaluation for this ECR. Decommissioning Technical Specifications LC 3.2 compliance will be verified by the performance of Decommissioning Technical Specifications SR 3.2.1 and SR 3.2.2 during the Functional Test.
This FT will be performed with only one ventilation exhaust system train operating and lined up to the ACCS, and then with only one ventilation exhaust train operating and lined up to the Reactor Building.
- 1. Seismic Analysis / Seismic Interaction Not required. The Decommissioning Plan Section 3.4.9, Natural ,
Disasters, states, "The seismic qualification of the Reactor Building will be maintained during decommissioning.- No other new or existing systems or equipment are required to function during or following an earthquake." The ACCS will have no effect on the seismic qualification of the reactor building.
- 2. Stress Analysis An analysis was performed to assure the structural integrity of the ACCS ducting. Based on the calculated flow through the ACCS and the live and dead loads due to the ducting, Reference 2 calculated that the maximum stresses in the ducting are within allowable stresses.
- 3. Pinina/lianner Analysis The maximum stresses in the ducting analyzed in Reference 2, was based on the hanger and ducting supports specified in Westinghouse Drawing Number 6433E68 (Attachment to Reference 1).
- 4. liydraulic/ Pneumatic The analysis in Reference 2 determined that the existing system 73 fans were able to provide sufficient flow-through the two DRWP tool slots (minimum of 100 fpm per slot). With a minimum of 17,100 cfm of air flow through the system 73 fan in use, the minimum air flow through the DRWP tool slots is 104 fpm per slot. In addition, Reference 2 calculated the pressure drop through the ACCS, from the DRWP to the tie-in with existing system 73 ducting, and assures the-ducting is adequate. With the system flow at 19,000 cfm, the pressure
ECR-93-003 Page 9 drop through the system is 2.4 inches of water.
- 5. Thermal Effects The temperature variations of the air flowing through this system is minimal. The environmental conditions specified for the ACCS is 65*F -
105'F (Reference 1). This temperature range is of little effect and no thermal effect analysis has been performed.
- 6. Nuclear /Radiolocical/ALARA Analysis During actual breaking into system 73 for installation of the ACCS, radiological precautions will be taken due to the potential for internal contamination. The dose rate due to the potentially contaminated / tritiated air flowing through the ACCS while in operation is minimal. Any radioactive particulates that may be in the ACCS will primarily be removed by the roughing filters and the system 73 HEPA filters.
However, the particulate release to the atmosphere will'be monitored and sampled in accordance with the ODCM. The tritium that may be in 'che system and released to the atmosphere will be monitored and sampled in accordance with the ODCM.
- 7. Fire Protection Analysis There are no significant combustibles that would present a fire protection hazard. Any " hot work" that may occur due to installation of the ACCS will follow applicable procedures for hot work.
- 8. Environmental Analysis There are no environmental affects due to the operation or installation of this system. . Potential dust /non-radioactive particles that may be released via the ACCS would primarily be.
removed by the roughing filters and the system 73 HEPA filters.
ECR-93-003 Page 10
- 9. Compatibility of Materials. Eauipment and Processes All materials to be used in the ACCS'are compatible with the existing system 73 ducting / components. The specific quality requirements of the Westinghouse Team Project Quality Plan will be applied to the ACCS'and will be specified in Work Specification Number 2.3.2.9 and Work Package Number 2.3.2.9A.
The ACCS shall be in accordance with the Project Quality Plan, Attachment A, Item AS except for the' tie-in to system 73 which.
shall be in accordance with Attachment A, Item.C1.
While the ACCS is in operation, a small amount of water vapor from the shield water system will be entrained in the air leaving the DRWP. The ducting and roughing filters in the ACCS have been - selected with this as a requirement. The roughing filter housing is. an expanded area of the ACCS which -
results in a lower pressure area. In this area some of the water that is entrained in the air will condense. The '
roughing filter housing has a drain valve in it. If any water vapor is in the air that enters the system 73 ventilation system, the existing moisture separators will be adequate to remove it.
- 10. Accessibility for Insoection. Maintenance and Reoair Although a portion of the ACCS will be potentially located in a radiation area, and the entire system will be located in the reactor building which is a radiologically controlled area, the ACCS is totally accessible for any inspections, maintenance, or repairs.
- 11. Electrical Analysis There is no electrical installations or modifications associated with this ECR. The current electrical loading on the reactor plant exhaust fans will remain' essentially the same.
,. - ,. r -
ECR-93-003 Page 11
- 12. Accident Analysis Of the accidents analyzed in the DP Section 3.4, only a hea'vy load drop accident involving activated graphite assumes that the reactor plant exhaust system is in operation. During the installation of the ACCS, only one of the three reactor plant exhaust trains will be isolated and a clearanct placed on that train. This leaves the other two trains to provide for filtration. During the actual operation of the ACCS, one train will be used for the ACCS line up while one of the other two trains are available for taking a suction directly on the reactor building. Even if only one ventilation exhaust train is in operation (lined up to the ACCS _ or directly to the reactor building), as long as SRs 3.2.1, 3.2.2, and 3.2.3 have-been satisfactorily completed, the requirements of LC 3.2 will be met and the consequences of a heavy load drop analyzed in DP Section 3.4.5 will not increase.

l ECR-93-033 i Safety Evaluation _ i Page'4 Dackeround The reactor building ventilation exhaust HEPA filters (F-7301, F-7302, and F-7302S) are being temporarily replaced with HEPA filters that have the same filtration and flow specifications as i that required by the Decommissioning Plani but do not have the complete documentation as to what industry standards they conform to.
The installed delta pressure (DP) gages for F-7301, F-7302, and F-7302S (PDI 7323-3, PDI
. 7358-3, and PDI 7359-3, respectively) have a range of 0 to 3" water gage. The Decommissioning Technical Specifications (DTS) allow the HEPA filters to have a maximum DP of 6" and during wafer cutting operations a greater than 3" DP gage is desired. The HEPA filters are rated for at least 10" water gage DP. .
Temporary replacement filters for F-7301 and F-7302 that are DOP rated at h 99.97% will be used until the requirements of DTS 3.2 are applicable. Prior to handling activated graphite, HEPA filters will be installed that conform to the specifications called out in Decommissioning Plan Section 2.2.3.13. A permanent replacement of the DP gages for all HPA filters will be performed, using gages that have a range of 0 to 8" water gage.
EInlufttlen Ouestion 3(A)
Of the accidents analyzed in the Decommissioning Plan Section 3.4, only a heavy load drop _
accident involving activated graphite assumes that the reactor plant exhaust system is .in ,
operation. During the period when the DTS are not required, the newly specified HEPA filters will be used. Until such time as DTS I.C 3.2 is in effect, The HpPA filters are not required .
to be operable and the requirements specified in Decommiss$n'i3g lan Section 2.2.3.13 item 5 need not be met. Once qualified HEPA filters are installed and SRs 3.2.1, 3.2.2, and 3.2.3 have been satisfactorily completed, the requirements of LC 3.2 will be met and the consequences -
of a heavy load drop analyzed in Decommissioning Plan Section 3.4.5 will not increase. This will be accomplished prior to handling activated graphite. The newly specified gages have no effect on the accident analysis. Therefore, the probability of occurrence or the consequences of an accident or malfunction of equipment important to decommissioning safety previously evaluated in tne Decommissioning Plan has not been increased.
ECR-93-033 Safety Evaluation Page 5 Ouestion 3(B)
The replacement HEPA filters have the same rating for filtering pardculate. The replacement gages are virtually the same except for the gage indicating range. Therefore, the possibility of 4 an accident or malfunction of a different type than any' evaluated previously in the Decommissioning Plan has not be created. .
Question 3(C)
The only DTS that are applicabb to the HEPA filters are not applicable until handling activated -
graphite. There are no DTS that are applicable to the HEPA filter DP gages. The applicable requirements of the ODCM will continue to be in affect. Therefore, the margin of safety as defined in the basis for any Technical Specification or in the Decommissioning Plan has not been reduced. ,

ECR-93-032 1 Page 7 Design Inputs This ECR is addressing the temporary replacement of the reactor building ventilation exhaust HEPA filters (F-7301, F-7302, and F-7302S), that are specified as the required replacement filters, with filters that are adequately rated for the filtering of effluents from the reactor building. This temporary replacement is applicable only when the requirements of Decommissioning Technical Specifications (DTS) 3.2 are not applicable. Also, this ECR is j L addressing the permanent replacement of the installed delta pressure (DP) gages for F-7301, F- ~
7302, and F-7302S (PDI 7323-3, PDI 7358-3, and PDI 7359-3, respectively) that have a range of 0 to 3" water gage with gages 'that have a range of 0 to 8" water gage.
IIEPA Filters I l
Decommissioning Plan Section 2.3.3.13, item 5, Exhaust Filters, states:
The reactor plant exhaust filters consist of three units. Exhaust air entering the reactor plant exhaust filters will pass in sequence through a moisture separator and a high efficiency particulate air (HEPA) filter. The HEPA filters conform to the requirements of the following documents:
(1) MilSpec MIL-F-51068 (D)
(2) Underwriters Laboratories Standard UL-568-1977 l (3) USNRC Regulatory Guide 1.140 ,
(4) USNRC Regulatory Guide 1.52, Rev. 2 l (5) ANSI N509 (1976)
Each of the HEPA filter elements in each filter unit, manufactured from fiberglass conforming to MilSpec MIL-F-51079, is designed for a flow rate of 1200 cfm, with a l maximum initial (clean) pressure drop of 1 inch (water gage). Each filter unit is rated at 19,000 cfm to handle the output ofits associated reactor plant exhaust fan. The design specification requires that the maximum penetation is 0.03% when tested with thermally-generated mono-dispersed dioctylphthalate (DOP). smoke having a light-scattering geometric mean droplet diameter of 0.3 microns.
The only requirements for the temporary HEPA filters are the following:
(1) Sized to fit in the er.isting HEPA filter frames without modification (24" x 24" x 11%" deep).
(2) DOP rated at 2 99.97% efficiency with 0.3 micron particles.
(3) Rated flow of d 1200 cfm at 1" water gage DP.
These requirements specified for the temporary HEPA filters will ensure any potential I
L 9
4 ECR 93-033 Page 8 radioactive effluents are adequately filtered. Once these temporary filters are installed, that filter train will be declared inoperable per DTS LC 3.2 until HEPA filters that meet the requirements of the DP are installed and SRs 3.2.1, 3.2.2, and 3.2.3 are satisfactorily completed. The installation of these HEPA filters is not included in this ECR and shall be performed using a SSR.
DP Gages During top head wafer cutting, there is a large amount of smoke generated. This results in numerous filter change outs of the in-line filters (ACCS roughing filters, reactor building furnace filters, reactor building pre-filters, and the reactor building HEPA filters). When all of the filters upstream of the HEPA filters are clean and the HEPA filters are partially loaded, the DP, on the HEPA filter is at its highest. The gage for reading HEPA filter DP indicates 0 to 3" water gage. There are times when a slightly higher indication is desired to monitor HEPA filter performance. In addP%n, DTS SR 3.2.2 states, "A pressure drop across the HEPA filter ofless than 6 inches of water gauge at 90% of the filter design flow rate will indicate that the filters are not clogged by excessive amounts of foreign matter." A 0 to 8" gage is being specified for this application. The following is a comparison of the two gages.
Vendor: Dwyer Dwyer Model: Magnehelic 2008 Magnehelic 2003C Gage Range: 0-8" water gage 0-3" water gage Gage Increments: 0.2" 0.2" Gage Accuracy: 2% of full scale i 2% of full scale The only item that is not equivalent is the gage accuracy. However, the required accuracy forph@
thi2 application is well within 2% ~of full scale (8") which is 0.16" water gage vs. W O.c6 for the 0-3" gage. This accuracy is sufficient to demonstrate compliance with DTS requirement of 6" water gage. The installation and calibration of these gages is not included in this ECR and shall be performed using a SSR.
