4.0 Post-Accident Samplino System. Item II.B.3

!

4.1 Position i

NUREG-0737, Item II.B.3, specifies that licensees shall have the capability to promptly collect, handle, and analyze post-accident samples which are representative of conditions existing in the reactor coolant and containment atmosphere. Specific sampling and analysis criteria are denoted in the licensee's commitments to the NRC relative to the specifications contained in NUREG-0737.

i I

4.2 Documents Reviewed and Review Method The implementation, adequacy, and status of the-licensee's post-accident i

sampling, monitoring, and analysis systems were reviewed against the criteria identified in Section 3.0 and in regard to the documents listed in Attachment 2 of this Inspection Report.

The licensee's performance relative to the above criteria was determined by interviewing cognizant personnel, reviewing applicable documentation and observing sample collection, handling and analysis.

4.3 System Description and Capability The licensee has installed a Post Accident Sampling System (PASS)

which is of a standard design used in Yankee plants.

It has the capability to obtain unpressurized undiluted or diluted samples of reactor coolant from reactor coolant loops one and three, residual heat removal (RHR) pumps A and B, RHR vault sumps, and the primary auxiliary building (PAB) sump. Also the licensee's PASS has the capability to sample dissolved gases (hydrogen) in liquid samples.

The system can collect samples from a pressurized or unpressurized reactor coolant system.

In addition, the licensee has installed a PASS for sampling containment air. The sample line is heat traced.

Redundant containment hydrogen analyzers provide an additional containment hydrogen analysis capability.

i Analysis of liquid samples for boron, chloride, radioactivity, and-

dissolved hydrogen are performed in the laboratory using an automatic potentiometric titration apparatus, ion chromatograph, gamma spectrometer, and gas chromatograph respectively. Analysis of containment air samples for radioactivity and hydrogen are performed'

using a gamma spectrometer and gas chromatograph, respectivel so

4.4 PASS Performance Testing Grab samples of reactor coolant and the containment atmosphere were

,

collected during operational tests of the liquid and containment air

post accident sampling systems on November 29, 1989. All important phases of the operations were observed by the inspectors.

During the testing, licensee personnel demonstrated the integrated ability to

[

collect and analyze a liquid sample within the time and accuracy constraints of NUREG-0737, II.B.3.

Portions of the test involved the licensee's personnel collecting samples under simulated accident conditions while using full protective clothing, self-contained

breathing apparatus, and electronic communications devices.

Licensee

personnel also demonstrated the ability to collect and analyze a l

containment air sample within the constraints of NUREG-0737. However,

-

they could not demonstrate that the samples could be collected, i

transported and analyzed within the personnel radiation dose constraints

!

of NUREG-0737, Item II.B.3.

This is further discussed in Section 9.0 i

of this report.

!

Overall, the licensee's chemistry personnel demonstrated a good

understanding of their pr.cedures indicating chemistry personnel

,

were properly trained in procedures. Detailed documentation for

,

personnel qualification on procedures was available.

4.4.1 Reactor Coolant Sampling i

The reactor coolant sampling system is designed to obtain f

samples of liquids and dissolved gases during all modes of operation.

During this operational test, samples were

,

collected from the RHR system because the reactor was shutdown. Although both liquid and dissolved gas samples could

be obtained from the prescribed sampling points, the following

items were discussed with the licensee for possible clarification or improvement:

-Although the liquid samples are unpressurized samples, the licensee pressurizes the sample system up to approximately 55 psi with argon prior to removing diluted liquid. The sample is drawn from the system through a septum using a syringe with a needle.

The syringe in use-during the operational test was a plastic syringe. The licensee had

,

no pressure rating data for this syringe. After discussing i

this matter with the inspector, the licensee produced a glass syringe with suitable pressure rating for sampling at 55 psi and stated that this syringe would be used for future liquid sampling.

]

,

E u

,

.

-The inspector walked down selected portions of the PASS reactor coolant sampling lines in the containment and the containment enclosure.

The installed lines and valves were consistent with drawings. The inspector noted that the electrical junction box (Node U9Z) for PASS liquid sample return valve (SS-FV-2857) exhibited loose cable conduit fittings. The licensee issued a work request and adequately tightened the fittings.

No other problems were noted.

-The inspector noted that the fume hood exhaust was not working during the licensee's preparation of liquid PAS $

samples in the fume hood for counting. Also, an alarm to indicate a malfunction of the fume hood was not working properly.

The licensee revised the checklist for Procedure CSO925.15 to include a check that the fume hood. alarm is operable; prior to personnel preparing samples in the hood and that the hood was operating properly.

-During performance of the PASS sample analysis in the'

chemistry laboratory, several individuals were observed leaving.the chemistry laboratory without frisking.

,

The licensee counseled department personnel about not using installed personnel contamination monitors.

-During collection of PASS liquid samples, a communication device worn by a chemistry technician failed and no spares were readily available.

The licensee placed three additional communications devices in the emergency lockers as spares.

-The sample team that was dispatched to the Combustible Gas Analyzer Room to collect a containment atmosphere sample did not have any way of determining if the analyzer room exhibited an explosive atmosphere. Also, the personnel did not have flashlights or other equipment that was certified for use in explosive' atmospheres.

The licensee's chemistry personnel borrowed a hand-held explosive gas meter from the instrumentation and control group. The licensee's chemistry personnel initiated action to obtain a hand-held hydrogen monitor and train personnel on its use. The licensee also obtained flashlights certified for use in explosive atmospheres._ The licensee also rigged long sampling lines to air sampling pumps to collect samples in explosive atmospheres.

!

,

so-

.-

-The licensee did not provide any protection inside the PASS laboratory fume hood to prevent the hood from becoming contaminated during sample handling.

The licensee placed Herculite in the hood to prevent the hood from becoming contaminated.

-During the PASS liquid sample preparation in the PASS laboratory fume hood, a chemistry technician was observed pouring PASS liquids down the wrong cup sink.

The licensee sealed over this cup sink to prevent liquids from'being poured down it.

-A chemistry technician, preparing PASS samples in the PASS laboratory fume hood, was observed not using shielding to reduce the accumulated dose to his extremities.

The licensee revised Procedures CSO925.11 and CSO925.02 to include cautions about shielding hot samples when not actually working with them.

-During collection of liquid samples at the PASS panel, there was a potential for liquids to drip on the floor and contaminate the floor of the PASS sample room.

The licensee added a precaution to Procedure CSO925.01 to ensure a method is used to collect drips, The following item will be reviewed during power operation:

-The samples taken during the operational tests were taken from the RHR system because the reactor was shutdown. The licensee has yet to use the. PASS to take and analyze samples from the reactor coolant system at operating pressure and temperature and compare these results to the sample results obtained from the normal reactor coolant system sampling points.

The licensee stated that this test of the liquid PASS system would be performed.

Required-training on revisions to the procedures as discussed above will be completed by January 19, 1990.

4.4.'

Containment Air Sampling The containment air PASS provides-for sampling the containment atmosphere from either of two sampling points that draw a sample from near the top of containment.

These are the same sampling points used for the containment hydrogen analyzers. The containment hydrogen analyzers must be operating in order to take a containment air PASS sample. During this test, containment air samples were taken with the "B" hydrogen analyzer train in servic.

..

.

Although the containment air sample was taken and analyzed as required, the following items were discussed with the licensee as items requiring attention:

-The licensee's procedures contain no specific guidance'on containment gas sample dilution and preparation after the containment gas sample is returned to the laboratory. As witnessed during this operational test, the sample for gamma isotopic analysis was prepared in a manner such that the amount of gas in the counting container was not known.

The licensee stated that this item would be reviewed and the necessary procedure changes would be made. Subsequent to this inspection, the licensee revised Procedure CSO925.02 so that a fixed volume of gas, 0.5 m1, is transferred to the counting container.

-The containment noble gas results from the laboratory sample analysis appear not to be in a form which can be directly applied to the licensee's core damage assessment methodology.

The noble gas analysis is performed on a sample at ambient laboratory pressure, whereas the actual conditions in con-tainment may differ from this; the containment atmosphere may be at a higher pressure.

The licensee applies no_cor-rections to the laboratory noble gas results to reflect the difference between the sample pressure and the actual containment pressure. The core damage assessment methodology requires that the sample result indicate the noble gas con-centration in containment. The licensee stated that this area would be reviewed and appropriate action taken.

Subsequent to this inspection, the licensee modified the following procedures so that the licensee's laboratory results would be in a form suitable for use with the core damage assessment methodology.

Procedure 051023.71, was modified to include verification

-

that the combustible gas control (CGC) sample bomb valves are open when checking to ensure that the sample bomb is in place.

Procedure CSO927.07, has been modified to clearly state

-

the valve manipulation sequence necessary to obtain a containment gas sample. This procedure was also modified to ensure that the temperature and pressure ia containment at the time of sampling will be noted.

Procedure CSO925.11 and CSO925.02, have been modified

-

so that gas sample volumes used in radioactivity analysis calculations are now corrected to sampling containment conditions.

percent hydrogen results to standard temperature and

pressure (STP) cond'tions. This correction will permit

!

the assessment of core damage conditions in that core

damage assessment depends upon the number of moles of

!

hydrogen generated, and the number of moles is l

proportional to volume after correction to STP conditions.

]

!

-The containment atmosphere sample line is heat traced to ensure there is no condensation of moisture during sampling. The inspector

!

was informed by the licensee on December 18, 1989, that the heat i

trace could not reach a temperature of 300'F.

Such a temperature

.

t is predicted during a postulated accident situation, The licensee stated that a design change was immediately initiated to upgrade the haat tracing to cnsure collection of a representative i

sample.

This design change will be completed and operational by

,

,

January 16, 1990.

!

The licensee indicated all appropriate documents would be updated i

by January 16, 1 0 0 and that all appropriate personnel would be i

trained in the change by January 19, 1990.

.

4.5 Analytical Capability

The licensee's commitments relative to range, uncertainty, and analytical

capability are contained in the Final Safety Analysis Report (FSAR)

l l

'

and the Seabrook Safety Evaluation Report (SER), NUREG 0896. The SER

.

specifies that the licensee's methods and procedures are consistent

[

with the requirements of NUREG-0737.

"

l 4.5.1 Chloride

The licensee's method of chloride analysis is ion chromatography.

The licensee has set up a dedicated ion chromato0raph (IC) for i

the analysis of PASS samples.

The' separator column for the chromatograph is located behind a lead shield in a fume hood.

Chloride standards were submitted to the licensee for analysis.

The standards were prepared by Brookhaven National Laboratory (BNL) for the NRC and were submitted to the licensee at three

,

concentrations over the range for which the PASS IC is calibrated, j

The licensee's analysis results were acceptable, a

Although the licensee's analysis results were acceptable, the i

following matter was discussed with the licensee for clarification or improvement.

L sc

,

12-The licensee performs a one point calibration of the IC at 20 ppb and then performs a quality control (QC) check at 10 ppb. However, in order to meet the PASS requirements for range and sensitivity the IC is set up to analyze chloride concentrations up to 100 ppb.

The licensee has performed linearity checks of the IC over this range.

The inspector discussed this matter with the licensee and suggested that the calibration be performed at the high end of the measure-ment range and the QC check be performed at the' low end..

The-licensee indicated that the calibration would be performed between 80-100 ppb and a QC check would be performed at 10 ppb. The licensee further indicated that one point calibratior,s were performed because of the-limited capability of the integrator interfaced to the IC, but that additional instrumentation was being procured that would permit multipoint calibrations.

The analysis results.are listed in Attachment 3.

Subsequent to this inspection, the licensee' revised Procedure CSO925.06 to require calibration at between 80-100 ppb.

Required training on this procedure revision will be completed by January 19, 1990.

4.5.2 Boron

'

Boron analysis is performed by potentiometric titration after manitol addition to the sample to form a complex acid.

The titration is performed in the laboratory using an automatic d

titration apparatus. The sample analysis takes place in a fume hood behind a lead shield.

Boron standards prepared by BNL for the NRC were submitted to the licensee for analysis to cover the range from 1 to 10 ppm.

The licensee's results were acceptable and are listed in Attachment 3.

4.5.3 _ Radioactivity Analysis Gamma isotopic analysis of both liquid and gaseous PASS samples is performed using the licensee's routine gamma spectrometry system. This gamma spectrometry system is located in the chemistry counting room which is adjacent to the hot chemistry laboratory.

A specially configured shield and germanium (Ge) detector, located.

l in the chemistry laboratory, is interfaced to the gamma spectrometry system and is used for the analysis of PASS samples. The shield is designed so that different collimators can be inserted between the sample and the detector.

The licensee has performed a separate calibration for each collimator, sample position, and counting geometry. Due to the absence of measurable radioactivity in the reactor coolant system, actual radioactivity measurements were not made by the licensee, but were simulated using the samples obtained from the operational tests.

!

j

.,

.

4.5.4 Hydrogen and Dissolved Gas Hydrogen analysis of the PASS liquid dissolved gas sarrple and the PASS containment gas sample are performed using the gas chromatograph located in the hot chemistry laboratory. The gas chromatograph is vented to the laboratory fume hood exhaust system.

Due to the absence of hydrogen in the reactor coolant system, actual hydrogen analyses were not performed but were simulated using the samples obtained from the operational tests. This enabled the licensee to demonstrate the adequacy cf PASS sample hydrogen analysis procedures.

5.0 Noble Gas Effluent Monitor, Item II.F.1.1 5.1 Position NUREG-0737 Item II.F.1.1 requires the installation of noble gas monitors with an extended range designed to function during normal and accident conditions. The criteria, including the design range of monitors for individual release pathways, power supply, calibration and (Aher design considerations are set forth in Table II.F.1-1 of NUREG-0737.

  • 5.2 Documents Reviewed and Review Methods The implementation, adequacy, and status of the licensee's

<-

monitoring systems were reviewed against the criteria identified in Section 3.0 and in regard to documents listed in Attachment 4.

The licensee's performance relative to these criteria was determined by interviewing the principal persons associated with the design, testing, installation and surveillance of the high range gas monitoring systems, reviewing associated procedures and documentation, examining personnel qualifications and direct observation of the systems, 5.3 Description and Capability The Seabrook Station has one release path for gaseous effluents, the Unit 1 vent, which is installed outboard of the Unit 1. containment and which discharges to the atmosphere near its top. To fulfill the NUREG-0737 requirements, it is monitored by a General Atomics (GA)

Wide Range Gas Monitor (WRGM) which is located on the 53' elevation in the Primary Auxiliary Building.

The WRGM provides for a full range

The licensee was ' performing surveillance testing of the WRGM consistent with Technical-Specification requirements..

The licensee's personnel exhibited an excellent unde'rstanding of the system operation and procedural req'uirements.

The licensee's personnel ~-

responsible for performing calibration and surveillance of the WRGM were provided training on the operation of the WRGri by-the vendor.

Also, the' individuals performing calibrations and-surveillance of the WRGM had written the procedures;to perform these functions.

The inspector's review indicated the compensatory monitoring provided was for low activity effluent sampling. At the time of this inspection, the licensee did not have.in place methods to implement Technical Specification 6.7.4,f., Accident Monitoring Instrumentation.

This

'

section requires the licensee.to-have in place backup instrumentation for use in monitoring high activity effluent releases. This section requires the backup instrumentation prior to exceeding five percent =

rated power.

The licensee's facility has not exceeded five percent

-

rated power. The licensee did not have'in place a backup monitor-toi provide'for continuous monitoring of post-accident noble. gas

,

releases. The licensee immediately initiated design changes to, provide for a backup high-range noble gas effluent monitor to meet

~

Technical Specification 6.7.4.f. requirements..The licensee indicated that the design change will be completed by January 16, 1990.- The licensee indicated that appropriate training of operations, chemistry, and radiation protection personnel will be completed by January 19, 1990. The licensee further indicated-that appropriate drawings would be updated by January 16,- 1990.

The licensee-could, however, collect grab samples and analyze these samples. The licensee's cquipment could analyze highly radioactive post-accident samples of noble gas.

-

The licensee has installed General. Atomics GA RS-42A' GM tubes: on the four main steam lines.

These detectors met the requirements of

-

NUREG-0737, Attachment II.F.1-1.

The licensee =has established 'J'

factors for_use in converting dose rate readings from the detectors to a release rate. Procedures for determining release. rates, which incorporate these factors were established. Control room personnel were knowledgeable in the procedures. The inspector noted that the-procedures did not incorporate corrections for. two phase flow thru the main steam' lines. The licensee indicated that'the corrections had been removed from the procedures. The licensee evaluated the

>

inspector's finding and concluded that the correction for two phase flow would be.re-inserted into the procedures.

The licensee committed to revise the procedure by January 12, 1990'and to train appropriate personnel by January 19, 1990.

The licensee has established backup monitoring capabilities for the monitors.

The backup monitoring consists of portable: instrumentation.

Procedures defining the backup monitoring are~available. The detectors were properly calibrated and tested by knowledgeable personnel.

6.2 Documents Reviewed and Review Method.

The implementation, adequacy and status of the licensee's sampling and analysis system and procedures were reviewed against the criteria identified in Section 3.0 of this report and in regard to the documents listed in Attachment 4.

,

The licensee's performance relative to'these criteria was determined-by interviewing the principal persons associated with the design, testing, installation, and surveillance'of the systems for sampling and analysis of high activity radioiodine and particulate effluents, by reviewing associated procedures-and documentation, by reviewing personnel qualification, and by direct observation of the systems.

,

6.3 Description and Capabilities The WRGMs sample conditioning skid contains a module of three unshielded particulate-iodine samplers for the low range pathway, which has a rated flow of I cfm and three shielded particulate-iodine samplers L

'

for the mid-high range, low-flow 0.06 cfm path, which is' selected-automatically by the radiogas concentration.

Continuous sampling is-provided by the selection at one of two samplers in the active flow path. The third is intended for timed' grab sampling, which may be,

performed locally or remotely from the Control Room.

The original installed sampier had a 96' lorg, " outside diametric (0.D.). diameter sampling line from the plant vent to the WRGM skid.

NRC staff review concluded that the k line was unacceptable due to poor iodine sample transmission.

l but not completely to the sample conditioning skid.

It was not clear that this temperature (65'F) would preclude condensation in the sample

<

line. The licensee could not provide justification to support the i

65*F heat trace temperature.

'

The licensee immediately initiated a review of this: matter and elected.

to install. higher temperature heat. trace on the sampling line.. The_

i licensee indicated heat trace with a temperature of 120 F would be installed and operable by January 16, 1990. Appropriate documents'

would be updated to reflect this change. The licensee also indicate:d:

..

that. appropriate personnel would be trained 11n this change. by January 19, 1990 if determined to be necessary.

,

To achieve high sampling flow-rates during accident conditions (when the lower flow path would.be selectad on the basis of mid-high range gas concentrations) and yet to minimize collected activity on a sample, the licensee has installed a design modification ~ (688-DCR-605)..which includes a flow splitter close to the-sample conditioning skid.-

Manually operated valves and quick-connect ports were. installed to.

facilitate the connection of a portable pump that can maintain a high flow under accident conditions in a path which bypasses the low range samplers and gas detectors. However, the licensee's procedure calls for the use of this arrangement only for grab sampling. At other.

times, the valving would be realigned to draw a-sample from the stack through the " line and to one of the two continuous sampling-positions,

'

in order to collect a continuous " archival" sample. This essentially results in grab samples that are representative but continuous " archival" samples that have questionable representativeness.

The licensee concurred in the above observation and revised j

Procedure CS0925.07 to provide for collection of a representative archival sample by returning the continuous sample collection to the original larger diametric (3/4") sample line. The lower flow rate l

pump will draw a sample from the larger diameter (3/4") sample line instead of the smaller diameter ( ")- sample line.

The continuous archival sample will be drawn through a second cartridge thereby

-

l allowing for correction of the activity on the cartridge collected L

via the h" 0.D. line.

Required training on the above procedure revision will be completed by January 19, 1990.

I In a walk-through of the licensee's procedures for obtaining and '

analyzing of simulated highly radioactive sample from the WRGM, it-was established the procedures did not provide for the installation

-

of a fresh sample in the grab sample position at the time a sample

'

-was pulled from it.

It was also. evident that cross-contamination of.

the components of the sample assembly was possible during its disassem)1y,

,

due to their random storage behind a_small open shield within the hood in which its disassembly was performed.

H The samples are taken to the laboratory for analysis.-.The licensee's sample analysis capabilities meet the guidance contained in NUREG-0737,-

Item II.F.1-2, Sampling and Analysis of Plant Effluents. The licensee's--

personnel exhibited a good understanding of the system operation and -

-i procedural requirements.-

i As discussed in Section 5.3 of this report, the WRGM was out-of-service t

because of a sample pump problem.

As a result, the licensee was also-collecting a continuous particulate or iodine sample of plant effluents using a backup pump. The licensee's compensatory sampling meet Technical-Specification requirements.

The inspector noted-that the backup sample method was designed for low activity normal samples.

The filter cartridge was not shielded.

Consequently, under accident conditions, radiation dose rates on the cartridge could preclude change-out of-the cartridge. The inspector noted~a backup method to collect and handle particulate-and iodine-samples of plant effluents under accident} conditions is required by Technical Specification 6.7.4.f.

A backup method of monitoring to-e implement Technical Specification 6.7.4.f. was not inplace. A backup

.

method is required by Technical Specifications prior to exceeding five percent of rated power.

The licensee immediately initiated a design change to provide for a backup particulate and iodine sampling system to meet Technical

,

Specification 6.7.4.f.

The licensee indicated the change would be installed and operable by January 16, 1990 and' appropriate personnel would be trained in the change and associated procedure revisions I

by January 19, 1990. 'The licensee also indicated. appropriate documents would be updated by January 16, 1990.

6.4 Findings

The system as reviewed meets the guidance specified in Attachment l'

II.F.1-2 of NUREG-0737.

However, the following matters requiring licensee attention were identified.

'

-

l l

Provide appropriate documentation to justify the 65 F plant

!

vent sample line or increase the temperature to preclude

'

condensation in the sample lines.

Establish. backup capabilities for the wide range particulate

and iodine sampler to meet Technical Specification 6.7.4.f.

19 The following items for clarification or improvement were identified:

Inspector review of the change out of WRGM filter media and-

-

cartridges in the PASS laboratory fume hood indicated that the change-out operation did not-adequately ensure the new filter-media-or cartridges would be prevented from becoming contaminated when handled in the chemistry laboratory fume hood. Also,- there were no provisions for inspection of the filter cartridge 'O'

rings.

The licensee revised Procedures CS0925.11 and CS0925.02 to improve contamination control-and handling and loading of new -

filter media and cartridges.

The ' procedures also were revised to require inspection of the filter media 'O'

rings..In addition, the licensee provided spare backup filter media and catridge holders. The. spare cartridge holders would be.loadesi and ready for use.

The licensee's procedures contained a statement that plant

-

effluent samples exceeding 300 mR/hr were not to be brought back to the counting lab.- It was unclear what the basis for this statement was.

The licensee revised Procedure CS0925.07 to eliminate.this-

!

limit.

The licensee's procedures and program provide for analysis of post-accident effluent samples consistent with-NUREG-0737, Item F.1-2.

Required training on the above procedure revisions will be completed

by January 19, 1990.

7.0 Containment High-Range Monitor. Item II.F.1-3 7.1 Position i

NUREG-0737, Item II.F.1-3, requires the installation of two

!

in-containment radiation monitors with a maximum range of 1, rad /hr l

to 10 rad /hr (beta and-gamma) or alternatively 1 R/hr to 10 R/hr (gamma only). The monitors shall be physically separated to view a i

large portion of containment and developed and qualified to function in an accident environment. The monitors are also' required to have an energy response as specified in NUREG-0737, Table II.F.1-3.

7.2 Documents Reviewed and Review Methods The implementation, adequacy, and status of the installed high-range containment monitors were reviewed against criteria set forth in Section 3.0 of this report and in regard to documents listed in

20 The licensee's performance relative to the above criteria was deter-mined by interviewing the principal persons associated with the' design, testing, installation and surveillance of high-range containment.

monitors, reviewing procedures and documentation, examining personnel qualifications and direct observation of the_ monitoring system.

7.3 System Description The licensee has installed two General 'tomics high-range

.

containment monitors on the operating floor of containment approximately 180 apart. The detectors, Model RD-23,'are Reuter Stokes RS-C3-1006-201 detectors.

The detectors are connected to field installed Class IE ITT Surprenant' cables. - Cable splices are protected with Raychem 300 WCSF-N. heat shrinkable tubing - Detector readout and data recording are provided in the Control Room.

7.4 Findings Within the scope of the review, the following-items were reviewed-and verified to-conform with NUREG-0737:

detector location

electrical separation

range and energy response

vendor type calibration

onsite calibration

redundancy

environmental and seismic qualifications The establishment and implementation of Technical Specification required calibration and surveillance test procedures was also i

verified.

The detectors were calibration and surveillance tested by I

knowledgeable personnel.

Within the scope of this review, the following items were identified I

which the licensee resolved:

The environmental qualification package for the high-range

-

'

containment monitor did not specifically demonstrate qualification of the containment high-range detector, cable and cable connector, as a configuration.

The licensee contacted General Atomics, the system vendor,-who

18.0 Improved In-Plant Iodine Instrumentation Under Accident Conditions, Item III.D.3.3 8.1. Position NUREG-0737, Item III.D.3.3, requires that each licensee provide equipment and associated training and procedures for accurately determining airborne iodine concentration in areas within the facility where plant personnel may be present during an accident.

8.2 Documents Reviewed and Review Methods The implementation, adequacy, and status of the licensee's program for in plant iodine monitoring under accident conditions was reviewed against criteria set forth in Section 3.0 of this report and in regard to documents listed in Attachment 6 to this report.

The licensee's performance relative to the above criteria-was determined by interviewing cognizant personnel, reviewing documents, and direct observation by-the inspector.

8.3 Description of Methodology and Capabilities L

The licensee will use portable grab sampling with subsequent i

analysis of the filter media as the. principle means of determining

the airborne radioactive concentrations in' areas within the facility j

where plant personnel may be present during an accident. The

'

licensee had an adequate supply of low flow rate-sample pumps for use in collecting samples. The licensee also had an adequate supply

,

of filter media (charcoal cartridges and silver zeolite cartridges).

-

'

The media were restocked when supplies decreased to a specified minimum value.

The licensee also had a stand-alone continuous air monitor in the Control Room.

The monitor (NMC Model AM-221B) had the capabilities

-

to monitor radioactive particulates, iodines and noble gases..

Appropriate personnel were trained on-the equipment and procedures for use in determining airborne radiciodine concentrations.

,

8.4 Findings

~

!

The licensee's program for determining the airborne radiciodine condition in areas within the facility meets the-guidance issued by the NRC in NUREG-0737, Item III.D.3.3.

The following items were identified as areas for clarification or improvement:

There were no provisions to purge high activity /high dose rate

-

charcoal and silver zeolite samples of noble gases prior to

'

analysis.

This would improve the lower limit of detection.

,

l

4.

,

1 V

.22 The licensee revised Procedures CSO925.02 and CS0925.11 to.-

provide for the purging of high activity /h_igh dose rate-charcoal and silver. zeolite samples if needed.

The licensee did not have data to demonstrate that

-

-

post-accident in plant radiation-sampling and analyses metho'ds were capable of a lower limit of detection of at least.1 X 10E-7 pCi/ml.

-The_ licensee subsequently evaluated the-capabilities of the sampling and analysis methods and determined that the sampling and analyses methods were capable of a lower limit of detection

-

of at least IL X 10E-7 pCi/ml for iodine-131.

Procedures do not account for. determining the iodine activity-

-

on sample cartridges.considering face loaded or uniform loaded cartridges. The procedures also do not address potential iodine breakthrough of. cartridges..

The licensee performed a study of=these items and subsequently-revised proceduru to provide. guidance to personnel regarding_

these items.

,

There were no procedures for determining the iodine activity of

-

cartridges from in plant sampling via use of dose rate

.

conversion factors. 'Such procedures'would be needed.if the gamma spectroscopy system was not available.

Such guidance was contained in'the licensee's off-site monitoring procedures. The licensee revised in plant Procedure ER 4.'8 to include guidance for using dose rates to determine iodine deposition -

on cartridges.

'

i The licensee's personnel held team briefings prior to dispatching.

'

-

teams to collect post-accident samples.

The briefing checklist-did not consider or address 1) the need for potential use_ of _KI, 2) inaccessibility to areas due to failures of the security system,

!

3) the loss of electrical power,- and 4) precautions.when -entering '

- ;

potential explosive atmospheres.

_ j The licensee revised checklists to ensure the above matters are

'

discussed.

There were no procedures for control and inventory of in plant

-

radiciodine samples or criteria to be used or to when such samples may be discarded.

-

The licensee revised Procedure ER 4.8 to establish' guidance for I

control, inventory and discard of in plant radiciodine samples.

!

Lq

.

23 There were no procedures to perform periodic surveillance-

-

testing of the continuous air monitor located in the control; room.

The licensee revised Procedure HD0955.33 to include a weekly operations check of the continuous air monitor located in the control room.

Required training on the above procedure revisions will be completed by January 19, 1990.

The inspector monitored a drill of the licensee's capabilities-

-

to collect and analyze in plant iodine samples. -The inspector noted that at least one individual who was required to use.a self-contained breathing apparatus had a full beard.

There

~

apparently was no policy regarding wearing of beards by personnel who may be required to respond during an accident situation.

The individual observed with the full beard subsequently shaved off the beard.

The licensee initiated a review of the policy on wearing of beards. The licensee subsequently issued to all

,

'

personnel a draft policy statement requiring personnel-who work

within the protected area to-be clean-shaven with-no facial _

hair in the area'of'the respirator' sealing surface.

9.0 General Design Criterion 19 (GDC) Dose Evaluations NUREG-0737, Item.II.B.3, Post-Accident' Sampling Capability, and-Item.

l 11.F.1-2 Sampling and Analysis of ' Plant Effluents, specifies that the; o

licensee be able to collect, transport, and analyze containment atmospheres, reactor coolant, and plant effluents' samples.without exceeding the GOC-19 personnel radiation dose limits.'(5' rem.whole-body

-

exposure and 75 rem extremities) during the duration of.the accident.

To ensure conformance with the GDC-19 limits,:the licensee performed a detailed habitability _ review in'accordance' with NUREG-0737, Item II.B.2,

.

Design Review of Plant Shielding and Environmental Qualification of-I Equipment for Spaces / Systems Which May Be Used in Post-Accident Operations.

The licensee used the radiation dose rate profiles from this study to

!

evaluate the capabilities to meet the GDC-19 values, j

The inspector ^ evaluated the Habitability Study and compared the results.

of the study with the radiation dose rate profiles.used by the. licensee, for a detailed time and motion study of each collection, transport, and analysis operation. The inspector performed an independent time and

-

i motion of selected sample collection, transport, and analysis operations.

The inspector concluded that the licensee's time and motion study covered the majority of actions which would be performed during collection, transport, and analysis operations.

However, some important portions of.

i

\\

u

L l

.

,

.-

the operations were not identified or taken into consideration during analysis of' samples in the laboratory.

These included preliminary set-up of the laboratory and multiple dilutions of reactor coolant samples for analysis'.-

Although these operations themselves are not dose intensive, the operations-occur in the' laboratory whose ambient background radiation level was estimated by the licensee to be 3.8' R/hr using the source term specified in NUREG-0737, Item II.B.2.

Using this background and timing personnel, the inspector concluded that it was likely that the GDC-19 whole-body-dose limit would be exceeded by certain: chemistry technicians.

The licensee's representatives acknowledged the findings and immediately initiated action to evaluate and adjust the sequence of operations and stationing of personnel to ensure that personnel dose limits would be maintained below the GDC-19 limits.

The-licensee performed a complete re-analysis of the basis-for the expected dose rates and re performed detailed time and motion studies.

The licensee concluded an inappropriate overly conservative factor was used for generating the 3.8 R/hr-background. Also, the licensee did not take account for shielding provided by the chemistry counting room.- The licensee also revised procedures and protocol to minimize stay-times in

.

-

high dose rate areas.

,

The inspectors review of the revised time and motion studies and bases subsequent to the inspection indicated all samples could be collected and analyzed within the dose constraints of GDC-19.

l 10.0 Confirmatory Issues-10.1 Confirmatory Issue No. 60 The NRC's staff review (Reference Seabrook Safety Analysis Report Supplement No. 5) of the licensee's post-accident effluent-

!

monitoring system concluded that the system conformed with Attachment 1 and 2 to TMI Action Plan Item'II.F.1 (NUREG-0737)

'

except for the capability to obtain representative-samples of plant effluents without excessive plateout. The licensee committed to change the sampling system design to improve.the sample collection and to provide an analysis of the capabilities of new design (Reference Seabrook Safety Analysis Report Supplement No. 8),

i NRC inspector review, during the inspection, found that the licensee

{

installed a complete, new large diameter (3/4") plant vent sampling

line. A complete in place test of the line was performed by the

!

licensee's contractor to evaluate the representativeness of samples collected via the new line. The contractor's review indicated an acceptable transmission factors.

10.2 Confirmatory Issue No. 56 Seabrook Station Safety Evaluation Report (NUREG-0896)' Supplement

!

No. 8 documents the licensee's commitment to install communication-isolation devices between the Radiation Data Management System'

i (RDMS) and the Safety Parameter Display System (SPDS).. The-electrical isolation devices were needed to prevent. faults'in the

'

monitors of the RDMS.

>

Supplement No. 8 described the isolation devices, provided a review _

-

and evaluation.of the devices, and described the testing of the isolation.

devices.

The devices (optical-isolators) were found acceptable for use in interfacing the RDMS and the SPDS.

The isolators also isolate the non-Class 1E portion of the RDMS from the Class 1E portion in the event of electrical problems.

The inspector determined that the SPDS was not electrically connected to the RDMS, Rather the SPDS obtained data from a station computer which obtains RDMS information.

Consequently, the licensee determined that no isolation devices to electrically isolate the SPDS from-the RDMS were needed. The licensee, however, did install optical. isolators between the Class IE and non-Class IE portion-of the RDMS.

The licensee also.provided isolation between the separate trains'of the Class 1E radiation monitors of the RDMS.

Upon isolation, each' Class IE' radiation-monitor in the RDMS becomes a stand-alone radiation. monitor with readout in the Control Room at a Class 1E panel.

The inspector reviewed applicable design change packages, discussed the packages with cognizant engineers and visually _ inspected field

installations of the optical _ isolators.

The isolators were installed on the containment purge and post-LOCA monitors,- the refueling crane monitors, and the east.and west control room air intake monitors.

These monitors are Class IE and provide important-information to control room operations' personnel.

i The design change was reviewed and approved by the Station Operation Review Commmittee.

The detectors were declared' operable.

The licensee's Quality Control group reviewed the installation to ensure seismic and-environmental qualifications were. maintained. The licensee plans to submit an update to the Final Safety Analysis Report to describe the changes.
