Enclosure 1 Page 1 of 53 Radiological Impact Assessment Browns Ferry Nuclear Plant January June 1990 I OUC 0 Potential doses to maximum individuals and the population around Browns Ferry are calculated for each quarter. as required in Section F.2 of the Radiological Effluent Manu'al. Measured plank releases for the reporting period are used to estimate these doses. Dispersion of radioactive effluents in the environment is estimated in accordance with the guidance provided by Regulatory Guides 1.109, l.ill and 1.113 using meteorological data and riverflow data measured during the period. Using dose calculation methodologies which are described in detail in the Browns Ferry Offsite Dose Calculation Manual, the doses are calculated and used to determine compliance with the dose limits contained in Browns Ferry's Operating License'. In this report, the doses resulting from releases are described and compared to quarterly and annual limits established for Browns Ferry.

SUMMARY

OF LI UID A GASEOUS EFFLUE RELEASES F RST HAL 1 0 Although nuclear plants are designed to contain the radioactive material created by the fission process, small amounts of this material escape from the fuel rods. Also, very small amounts of the structures and components of the systems become activated through the bombardment of neutrons and are worn away. This radioactive material can be transported throughout plant systems and released to the environment.

rborne Re eases The noble gas fission products do not mix with water and are given off in a gaseous form. A very small amount of solid radioactivity is given off along with these noble gases. The most significant releases are processed so that the radioactive material is filtered and/or decayed prior to release through the plant vents. Sampling and monitoring methods are used to determine the amount of radioactive material released. If these methods indicate that.

radioactivity in airborne effluents is above preset limits, then releases are terminated. Airborne releases* for each quarter in the period are given in Section 1 of this submittal.

u" Some small amounts of radioactive material migrate into the primary coolant water. The primary coolant water is routed through a~urification system to remove most of these particles; however, not all are removed. Some of the radioactive liquids may leak from pipes or valves in the system. These liquids are collected in floor

0 Enclosure 1 Page 2 of 53 and equipment drains and sumps. The collected liquids are then processed through a clean-up system, composed of storage tanks, recycling systems, and demineralizers, to remove contaminants. The purified water is then monitored to determine the amount of radioactive material remaining in the water prior to its release. Steps are taken to ensure that the amount of radioactivity released to the environment is as low as reasonably achievable (ALARA). If the levels of radioactivity are above preset limits, the releases are circulated through the clean-up system again for additional processing. All radioactivity released from the~plant into the Tennessee River is quantified prior to release. Liquid releases for each quarter in the period are given in enclosure 1 of this submittal.

Effluent Monitor n Plant paths through which radioactivity is released are monitored. These monitors record the radiation levels for each release. Monitors which are used for liquid releases will automatically alarm and stop any release which is above regulatory limits. Gaseous release monitors also provide alarming mechanisms to allow for the termination of any release above limits.

DOSE L S The U.S. Nuclear Regulator Commission (NRC) requires nuclear power plants to be designed, built, and operated in such a way that the levels of radioactive material released into unrestricted, areas is as low .as reasonably achievable (ALARA). To ensure that this is done, the plant's operating license includes Technical Specifications which govern the release of radioactivity. These Technical Specifications specify limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of these-effluents. These limits are set well below the NRC 10CFR20 limits which govern the concentrations of radioactivity and exposures permissible in unrestricted areas. This ensures that'radioactive effluent releases are ALARA.

The Technical Specification limits for doses at or beyond the site boundary from airborne noble gases releases are:

Less than or equal to 5 mrad per quarter and 10 mrad per year (per reactor unit) for gamma radiation, and-Less than or equal to 10 mrad per quarter and 20 mrad per year (per reactor unit) for beta radiation.

Enclosure 1 Page 3 of 53 The Technical Specification limit for the dose to a m'ember of the general public at or beyond the site boundary from iodines and particulates released in airborne effluents is:

Less than or equal to 7.5 mrem per quarter and 15 mrem per year (per reactor unit) to any organ.

The Technical Specificati'on limit for doses to a member of the general public from radioactive material in liquid effluents released to unrestricted areas, is:

Less than or equal to 1.5 mrem per quarter and 3 mrem per year (per reactor unit) to the total body, and Less than or equal to 5 mrem per quarter and 10 mrem per year (per reactor unit) to any organ The EPA limits for total dose to the public in the vicinity of a nuclear power plant, established in the Environmental Dose Standard of 40 OFR 190, are:

Less than or equal to 25 mrem per year to the total body, Less than or equal to 75 mrem per year to the thyroid, Less than or equal to 25 mrem per year to any other organ.

DOSE CALCULATIO S Estimated doses to the public are determined using computer models (the Gaseous Effluent Licensing Code, GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models are based on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113) for determining the potential dose to individuals and populations living in the vicinity of the plant. The area around the plant is analyzed to determine the pathways through which the public may receive a dose. The doses calculated are a representation of the dose to a "maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maximum values. Many of these factors are obtained from NUREG/CR-1004. The values chosen will tend to overestimate the dose to this "maximum" person. The expected dose to actual individuals is lower. The calculation methods and results of the calculations are presented in the following sections.

i, Enclosure 1 Page 4 of 53 DOSES 0 A BO NE E VENTS For airborne effluents, the public. can be exposed to radiation from several sources:

direct radiation from the radioactivity in the air, direct radiation from radioactivity deposited on the ground, i

inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited from the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation which is then eaten by milk and beef animals.

The concentrations of radioactivity in the air and the soil are estimated by the computer model GELC which uses the actual meteorological conditions to determine the distribution of the effluents in the atmosphere. Again, as many of the parameters as possible are based on actual site specific data. The model that is used to estimate dose, as well as the paramete'rs input to the model, is described in detail in Section 1.0 of the Browns Ferry Nuclear Plant Offsite Dose Calculation Manual.

irbo e Re ease Poi ts a d Meteorolo cal Data Meteorological variables at Browns Ferry are measured continuously.

Measurements collected include wind speed, wind direction, and temperature at heights 'of 10, 46 and 91 meters above the ground. Quarterly joint frequency distributions (JFDs) are calculated for each release point using the appropriate levels of meteorological data. A joint frequency distribution gives the percentage of the time in a quarter that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a given stability class A through G. The wind speeds are divided into nine wind speed ranges. Calms are distributed by direction in proportion to the distribution of noncalm wind directions less than 0.7 m/s (1.5 mph).

Stability classes are determined from the vertical temperature difference between two measurement levels.

There are four routine release points from Browns Ferry Nuclear Plant: the turbine building, the radwaste building, the reactor building, and the stack.

Enclosure 1 Page 5 of 53 Releases from the turbine building are considered ground-level releases to determine the dispersion of the airborne effluents. The ground-level JFD is derived from windspeeds and directions measured 10 meters above ground and from the vertical temperature difference between 10 and 46 meters.

Releases from the radwaste and reactor buildings are considered split-level releases to determine the dispersion of the airborne effluents. This means that portions of the release are treated as elevated while other portions are considered ground-level depending on the ratio of the vertical exit velocity to the horizontal wind speed. The split-level dispersion approach is implemented using a model that requires two complete quarterly JFDs for each effluent vent, one for the elevated releases and one for the ground-level releases. The ground-level portion of the split-level JFD is based on wind speeds and directions measured 10 meters above ground-level and from the vertical temperature difference between 10 and 46 meters. The elevated portion of the split-level JFD is based on wind speeds and direction measurements at the 46-meter level and the vertical temperature difference between 46 and 91 meters.

Releases from the stack are considered elevated-level releases to determine the dispersion of the airborne effluents.. The JFDs for elevated releases are based on wind directions and wind speeds measured at 91 meters and the vertical temperature difference between 46 and 91 meters.

The generally open terrain around BFN is not believed to cause any significant effects on the transport and dispersion of gaseous effluents from the plant.

Within 30 kilometers of BFN, the terrain is mostly gently rolling hills (30 meters). Between 30 and 80 kilometers the hills become larger to the north and south, and mountainous to the east and northeast. The Tennessee River/Wheeler Lake may have a minor effect on transport and dispersion in the immediate vicinity of BFN during periods of winds with a southerly component, overcast skies, and r'elatively high wind speeds. Then, the lower layer (10-46 meters) stability class tends to be more stable than would be expected.

However, during this infrequent condition, dose estimates will be conservative.

Enclosure 1 Page 6 of 53 xternal Ex osure Dose Ai bo e Ef lue ts Dose estimates for maximum external air exposures (gamma-air and beta-air doses) are made for points at and beyond the site boundary. These doses are calculated for all receptor points shown on Table 3. The reported dose is chosen for the offsite location with the highest calculated exposure during the quarter. The doses calculated for Browns Ferry Nuclear Plant for each quarter are shown below.

These doses are calculated based on the reported releases for noble gases for all receptor points shown on Table 3. The highest of these exposures is chosen and is assumed to be the maximum individual dose. The submersion doses calculated for Browns Ferry Nucl'ear Plant for each quarter are shown below.

t Enclosure 1 Page 8 of 53 Or a Dose Ai bo e E f ue ts Internal doses to organs due to releases of airborne effluents are estimated for the inhalation, ground contamination, and ingestion pathways. The ingestion pathway is further divided into four possible contributing pathways:

ingestion of cow/goat milk, ingestion of beef, and ingestion of vegetables.

Doses from applicable pathways are calculated for each real receptor location defined in Table 3. Doses are calculated based on the reported iodine and particulate releases. To determine the maximum organ dose, the dose contribution from the three pathways are summed for each receptor. For the ingestion dose, however, only those pathways that exist for each receptor are considered in the sum, i.e., milk ingestion doses are included only for locations where milk is consumed without commercial preparation and vegetable ingestion is included only for those locations where a garden is identified.

To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest site boundary location is added to each identified receptor. For ground contaminati'on, the dose added to the organ dose being calculated is the total body dose calculated for that location, i.e., it is assumed that the dose to an individual organ is equal to the total body dose.

The organ doses calculated for Browns Ferry Nuclear Plant for each quarter are shown below.

Since airborne releases are quantified on a per site basis, and the Technical Specification dose limits are given on a per unit basis, calculated airborne doses are initially compared to the per unit limit.

If this limit is exceeded, the release data is reanalyzed to determine which portion of the releases were attributable to each reactor unit.

Then these per unit releases can be used to calculate per unit doses which are compared to the per unit dose limits.

As is shown by the table, all calculated quarterly doses were well below the allowable limits established in Browns Ferry's Technical Specifications. For a comparison to previous releases and doses, graphs are presented as Figures 1 and 2 which show corresponding airborne releases and doses for the period 1980 to the present.

Enclosure 1 Page 10 of 53 DOSES FROM LI U D EFFLUENTS For liquid effluents, the public can be exposed to radiation from three sources:

the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactive material deposited in the river sediment (recreation).

The concentrations of radioactivity in the Tennessee River are estimated by a computer model whi.ch uses measured hydraulic data downstream of Browns Ferry.

Parameters used to determine the doses are based on guidance given by the NRC, (in Regulatory Guides 1.109) for maximum ingestion rates, exposure times, etc. Wherever possible, parameters used in the dose calculation are site specific use factors determined by TVA. The models that are used to estimate doses, as well as the parameters input to the models, are described in the Browns Ferry Nuclear Plant Offsite Dose Calculation Manual.

L u d Re ease Points a d Rive Data Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous. All routine liquid releases from Browns Ferry, located at Tennessee River Mile 294, are made through diffusers which extend into the Tennessee River. It is assumed that releases to the river through these diffusers will initially be entrained in one-fifth of the water which flows past the plant. The QWATA code makes the assumption that this mixing condition holds true until the water is completely mixed. at the first downstream dam, at Tennessee River Mile 283.0. The average river flows past the plant site were 122,875 ft3/s for the first quarter of 1990 and 34,054 ft3/s for the second quarter.

Dose Estimates Li uid E fluents Doses are calculated for recreation, consumption of fish, and drinking water for locations between the plant site and the mouth of the Tennessee River.

The maximum potential recreation dose is calculated for a location immediately downstream from the plant outfall. The maximum individual dose from ingestion of fish is assumed to be that calculated for the consumption of fish caught anywhere between the plant and the first downstream dam (Wheeler Dam). The maximum individual. dose from drinking water is assumed. to be that calculated at the nearest downstream public water supply

Enclosure 1 Page 11 of 53 (Champion Paper Company). This could be interpreted as indicating that the maximum individual, as assumed for liquid releases from Browns Ferry, is an individual who obtains all of his drinking water at the Champion Paper Company, consumes 21 kg (6.9 kg for a child) per year of fish caught from the Tennessee River between BFN and Wheeler Dam, and spends 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per year standing on the shoreline gust below the outfall from Browns Ferry.

The quarterly limit for liquid doses is the total site dose limit (the one-unit dose limit times 3). This is because,all liquid radwaste systems are common to all 3 units and the releases cannot be attributed to one particular reactor unit.

As is shown by the table, all calculated quarterly doses were well below the allowable limits established in Browns Ferry's Technical Specifications. For a comparison to previous releases'and doses, graphs are presented as Figure 3 which shows corresponding liquid releases and doses for the period 1980 to the present.

Enclosure 1 Page 13 of 53 OP A 0 DOSES Population doses for highest exposed organ due to airborne effluents are calculated for an estimated 627,000 persons living within a 50-mile radius of the plant site. Ingestion population doses are calculated assuming that each individual consumes milk, vegetables, and meat produced with the sector annulus in which he resides. Doses from external pathways and inhalation are based on the 50-mile human population distribution.

Population doses for total body ~and the maximum exposed organ due to liquid effluents are calculated for the entire downstream Tenne'ssee River Population. Mater ingestion population doses are calculated using actual population figures for downstream public water supplies. Fish ingestion population doses are calculated assuming that all sport fish caught in the Tennessee River are consumed by the Tennessee River population. Recreation population doses are calculated using actual recreational data on the number of shoreline visits at downstream locations.

Population dose estimates for airborne and liquid effluents are presented below.

Population doses can be compared'o the natural background dose for the entire 50-mile population of about 56,430 man-rem/yr (based on 90 mrem/year for natural background).

Enclosure 1 Page 14 of 53 DIREC D 0 External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs) deployed around BFN. The quarterly gamma radiation levels determined from these TLDs during this reporting period averaged approximately 17.1 mR/quarter at onsite stations and approximately 15.3 mR/quarter at offsite stations, or approximately 1.8 mR/quarter higher onsite than at offsite stations. This is consistent with levels reported at TVA's nonoperating nuclear power plant construction'ites where the average radiation levels onsite are generally 2-6 mR/quarter higher than the levels offsite. This may be attributable to natural varidtions in en'.ronmental radiation levels, earth moving activities onsite. the mass of concrete employed in the construction of the plants, or other undetermined influences. Fluctuations in natural background dose rates and in TLD readings tend to mask any small increments which may be due to plant operations. Thus, there was no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous effluents.

DOSE TO E S OF UB C S SI BOUNDAR No routine activities within the site boundary by members of the public have t

been identified which would lead to their radiation exposure.

~TOTAL DOS To determine compliance with 40 CFR 190, annual total dose contributions to the maximum individual from BFN radioactive effluents and all other nearby uranium fuel cycle sources are considered.

The annual dose to any organ other than thyroid for the maximum individual is conservatively estimated by summing the following doses:

the total body air submersion dose for each quarter, the critical organ dose (for any organ other than the thyroid) from airborne effluents for each quarter from ground contamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, the maximum organ dose (for any organ other than the thyroid) from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the environmental monitoring program.

This dose is compared to the 40 CFR 190 limit for total body or any organ dose (other than thyroid) to determine compliance.

Enclosure 1 Page 15 of 53 The annual thyroid dose to the maximum individual is conservatively estimated'y summing the following doses:

the total body air submersion dose for each quarter, the thyroid dose from airborne effluents for each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liguid,effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured by the environmental monitoring program.

This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance.

Cumulative annual total doses are presented in the following section of this report.

CO As a CITS'~0 resul t of operation of Browns Ferry Nuclear Plant for the second half of 1989, radioactive effluents were released to the atmosphere- and the Tennessee River. The released radioactivity resulted in estimated potential doses to the public which are well below the Technical Specification Limits and Regulatory Guidance. Cumulative doses for the calendar year are given below along with a comparison to the respective annual limits for the doses.

Since airborne. releases are quantified on a per site basis, and the Technical Specification dose limits are given on a per unit basis, calculated airborne doses are initially compared to the per unit limit.

If this limit is exceeded, the release data is reanalyzed to determine which portion of the releases were attributable to each reactor unit.

Then these per unit releases can be used to calculate per unit doses which are compared to the per unit dose limits.

2 The quarterly Technical Specification limit for liquid doses is the total site dose limit (the one-unit dose limit times 3). This is because all liquid radwaste systems are common to all 3 units and the releases cannot be attributed to one particular reactor unit.

ENCLOSURE 2 TENNESSEE VALLEY AUTHORITY SEMI-ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT BROWNS FERRY NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL REPORT JANU Y THROUGH JUNE 1990
Enclosure 2 Page 1 of 16 EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT
'UMMARY FIRST HALF 1990 The radioactive effluents for tlie first half of 1990 were normal for a three unit boiling water reactor plant. in its fifth year of an extended outage.
Because of the extended outage, only radionuclides with a long half-life (longer than a few months) have not decayed away and are being released to the environment. The radioactive decay is particularly significant for gaseous effluents because no fission gases or radioactive iodines are being released.
The only radioactive gaseous releases are very small quantities of particulate matter.
The radioactivity being released now in liquid effluents is primarily long half-life radionuclides that have been deposited on the surfaces of piping and components. During normal outage work this radioactivity is removed by process water that is purified and released to the river. The water purification process is unable to remove all the radioactivity before it is released to the river.
The release of radioactive material to the environment from Browns Ferry Nuclear Plant has been a small fraction of the 10 CFR 20 Appendix B and 10 CFR 50 Appendix I limits during the first half of 1990.
Enclosure 2 Page 2 of 16 EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION FIRST HALF 1990 Re ulato Li ts A. Fission and Activation Gases in Gaseous Effluent:
1. The release of fiss'ion and activation gases is regulated by the dose limits of 10 CFR 50 Appendix I. The air dose to areas at and beyond the site boundary due to noble gases released in gaseous effluents per unit shall be limited during any calendar quarter to g 5 mrad for gamma radiation and g 10 mrad for beta radiation; and during any calendar year to g 10 mrad for gamma radiation and g 20 mrad for beta radiation.
B and C Iodines and Particulates with half lives greater than eight days in gaseous effluents.
1. The release of iodines and particulates in gaseous effluent is regulated by the dose limits of 10 CFR 50 Appendix I. The dose to a member o'f the public from radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases with half live greater than 8 days in gaseous effluent released per unit to area at and beyond the site boundary shall be limited to any organ during any calendar quarter to g 7.5 mrem, and during any calendar year to g 15 mrem.
D. Liquid Effluents
1. The release of radioactive liquid effluents is regulated by the dose limits of 10 CFR 50 Appendix I. The doses or dose commitment to a member of the public from radioactive materials in liquid effluents released from each unit to unrestricted areas shall be limited during any calendar quarter to g 1.5 mrem to the total body and
< 5 mrem to any organ and, during any calendar year to < 3 mrem to the total body and < 10 mrem to any organ.

Enclosure 2 Page 4 of 16 EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION FIRST HALF 1990 D. Liquid Effluents The concentrqtioh of radionuclides in liquid effluents released at any time from "the site to unrestricted areas shall be limited to the concentrations specified in 10 CFR 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases.
2. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 pCi/ml total activity.
III. Average Energy Not applicable IV. Measurements and rox at ons o Total Rad oactivit A. Fission and Activation Gases:
1. Noble gases in the building vent and stack, gaseous effluent are continuously monitored. The flow rate of the stack is "continuously monitored and the building vent effluent'flow rates are calculated once a shift based on the configuration of operating exhaust fans. The flow rate data is consolidated weekly to determine the volume of. airborne effluent released from the plant. The noble gas monitor data is consolidated monthly to determine the total curies of noble gases released during the month.
2. Gas grab samples are taken and analyzed monthly to determine the relative noble gas activity concentrations. This information is used to apportion the total curies of noble gases r'eleased between different noble gas radionuclides.
3. The tritium concentration is determined by the analysis of a monthly grab sample for each release point.
B and C.
Iodines and Particulates
l. Iodines and particulates are continuous1y sampled on impregnated charcoal filters and particulate filters, respectively. The charcoal and particulate samples are replaced at least weekly and analyzed to determine specific activity concentrations. The specific activity concentrations and vent flow rate data are used weekly to verify that release rate limits were not exceeded. The specific activity concentrations and total volume of gaseous effluent are used on a monthly basis to determine the total curies of each particulate and iodine released during the month.

2. The gross alpha concentration is determined by analysis of a monthly particulate filter composite sample and strontium -89 and -90 are determined by analysis of a quarterly particulate filter composite sample for each release point.
D. Liquid Effluents
1. The gamma ray emitting radionuclide concentrations are determined for each batch by gamma ray spectroscopy analysis of a grab sample. The allowable release rate is calculated for each batch based upon the known dilution flop. The flow rate of the liquid effluent is continuously monitored and the total volume released in each batch is determined. The total gamma activity released in each batch is determined by multiplying the radionuclide concentrations by the total volume discharged. The, total gamma activity released during the month is then determined by summing the gamma activity content of each batch discharged during the month.
2. The gross alpha and tritium concentrations are measured on a monthly composite sample. The strontium -89 and -90 and iron
-55 are measured on a quarterly composite sample.

ENCLOSURE 3 TENNESSEE VALLEY AUTHORITY BROWHS"FERRY NUCLEAR PLANT SEMI-ANNUAL RADI(ACTIVE EFFLUENT RELEASE REPORT INOPERABLE RADIOACTIVE EFFLUENT INSTRUMENTATION REPORT JANUARY THROUGH JUNE 1990
Enclosure 3 Page 1 of 4 o e ab e Radioactive Eff ue t nstrumentation Re ort Browns Ferry Nuclear Plant (BFN) Technical Specifications (TSs) 3.2.D.2 and 3.2.K.2 requires the semi-annual Radioactive Effluent Release Report to include an explanation of why the required radioactive effluent monitoring instrumentation was inoperable for more than 30 days. This report covers the period from January through June 30, 1990.
The Radiological Effluent Technical Specification (RETS) became effective at BFN on May 6, 1987 during the current administrative outage. Due to changes in the operability requirements of radioactive effluent monitoring instruments resulting from RETS, a number of radioactive effluent monitoring instruments were declared technically inoperable on May 6, 1987, that were previously considered operable. Resources have been allocated to resolve these problems and others in order to establish compliance with the RETS.
The instruments that were inoperable for more than 30 days are:
Offgas post-treatment monitors, 2-RM-90-265, 2-RM-90-266, 3-RM-90-265, and 3-RM-90-266 Sample flow abnormal annunciator, 2-PA-90-262 The liquid radiological effluent instrumentation that were inoperable for more than 30 days include:
Residual Heat'Removal (RHR) Service Water Monitors,'-RM-90-133,'0-RM-90-134, 2-RM-90-133, 2-RM-90-134, 3-RM-90-133, and 3-RM-90-134 Liquid Radwaste Effluent Flow Loop, 0-FR-77-60
Enclosure 3 Page 2,of 4 Off as Post-t eat e t Monito s and Sam e F ow Annunciator LCO Numbers 2 a d a BFH TS Table 3.2.K requires the offgas post-treatment noble gas activity monitors and the associated abnormal sample flow alarm channels to be operable at all times. Contrary to this requirement, four of the monitors and one of the sample flow annunciators were inoperable for periods greater than 30 days.
On December 22, 1989, the Offgas Sample Flow Abnormal annunciator, 2-PA-90-262, was declared inoperable following normal surveillance testing.
In turn, the inoperable status of the pressure annuciator resulted in the inoperability determination of both Offgas Post-treatment Monitors, 2-RM-90-265 and 2-RM-90-266. A Maintenance Request (MR) 1020850 was written to troubleshoot and correct the annunci'ator. The root cause for the failed annunciator was traced to a defective offgas sample pump. (MR) 1029002 was written to replace the pump with the radiation monitors remaining. in an inoperable status.
On February 17, 1990, the 24 VDC power supply board to the Offgas Post-treatment Monitors, 3-RM-90-265 and 3-RM-90-266, was deenergized to support neutron monitoring system penetration work. The power suply board was returned to service and the monitors are awaiting functional testing.
Effluent releases via both pathways wex'e not permitted during'he inoperable periods. This was accomplished bP maintaining the unit offgas isolation flow control valves in the closed position which resulted in no additional compensatory sampling requirements.
Enclosure 3 Page 3 of 4 u d Radwaste Ef lue ow Loo -FR-LCO be BFN TS Table 3.2.D requires the Liquid Radwaste Effluent Flow Loop, O-FR-77-60, to be operable during releases via the radwaste system. Contrary to this requirement, the flow loop was inoperable during the entire reporting period. Manual compensatory measures were observed for all liquid releases for the reporting period.
The flow loop was declared technically inoperable on June 21, 1989, due to .
inaccuracies between the flow transmitter as compared to the actual tank levels. A Design Change Notice (DCN) H4536A was written to replace the dual channel flow instrumentation with a single channel digital instrumentation.
All field work and associated post-modification testing should be completed and the flow loop returned to an operable status within the next reporting period.
Enclosure 3 Page 4 of 4 es dua eat emova RHR Se vice Water onito s LCO Number a d DCR Number 1 and DCN Number H 4 BFN TS Table 3.2.D requires the RHR Service Water monitors, 1-RM-90-133, 1-RM-90134, 2-RM-90-133, 2-RM-90-134, 3-RM-90-133, and 3-RM-90-134, to be oeprable during the operation of an RHR loop and the associated RHR service water system. Contrary to this requirements, the six monitors were inoperable for periods greater than 30 days.
Footnote 2 of BFN TS Table 4.2.D requires that the RHR service monitors provide for control room annunciation if the monitor is not set in operate mode. The current 1-RM-90-133, 3-RM-90-133, and 3-RM-90-134 monitors do not provide this capability. Revision 1 of Design Change Request (DCR) 1687 was approved on September 29, 1986, to correct this issue. To support unit 2 restart, the RHR service water piping associated with these monitors has been physically cut and capped as a positive isolation boundary.
Monitor 1-RM-90-134 has been out of service due to seismic concerns which are being resolved under DCN H3949. A hold order has been placed to isolate and to remove from service the RHR service water piping associated with this monitor. The monitor should be returned to service upon completion of DCN H3949.
As a result of problems related to sample pump automatic starting circuitry, unit 2 RHR service water monitor, '2-RM-90-133, was'elared in inoperable on .
September 24; 1989. After an investigation, it was determined that the automatic pump start time delay logic does not allow fo'r charging the RHR service water headers. A DCN has been written to correct the problem.
Unit 2 RHR service water monitor, 2-RM-90-134, was declared inoperable when the 480V shutdown board 2B was deenergized on February 15, 1990. The RHR service water was isolated to the heat exchangers. The monitor was returned to service on June 18, 1990.
