Pago 1 of 11 CR/TSC HVAC INCPECTION QUESTION / RESPONSE Question 1: Rancho Seco's procedure for air balance of ventilation systems, M-111, "HVAC Maintenance Procedure for Air Balance of Ventilation Systems," is relied on for providing assurance that unfiltered air inleakage is within the bounds of the assumptions used in the dose calculations and toxic gas analyses, and the system otherwise functions as designed. In the initial request for additional information (RAI), eleven specific items were requested regarding M-111 and the results obtained.

Based on our review of the licensee's response to the initial RAI and our understanding that the licensee is performing a new air balance for the control room HVAC system in accordance with M-111, provide all final data sheets, results, evaluations, and conclusions based on the new air balance regarding the adequacy of the air flow rates assumed in the dose calculations and toxic gas analyses and concerning the system functions. Items 1(a),

1(1), and the concern noted in Iten 1(%) of the initial RAI remain applicable.

Response: The District performed a CR/TSC air balance (M-111) on February 2-3, 1988. This retest was performed on a continuous basis beginning on the day shift (2/2/88) until its completion on the night shift the next day (2/3/88).

Several flows were found outside of the design ranges.

These nonconformances are currently being reviewed (NCR-7588) and are expected to be acceptable based on the following:

Actual heat loads are less than design heat loads used to establish design flow values.

Location of several of the traverse points is inappropriate, resulting in anomalous data. In these cases, alternate flow measurements were used (i.e.,

grills / registers associated with the traverse flows).

Some of the flow data wac outside of the design values; however, when the actual measure data is reviewed the flows are considered adequate (e.g.,

control room supply and return flows).

t GCA 88-101 Attachment 1 Page 3 of 11 CR/TSC HVAC INSPECTION QUESTION /RES PONSE Question 2: R. G. 1.52, Position 5.d provides that leak testing of the carbon adsorber section should be conducted if the integrity of the adsorber is affected. Rancho Seco Technical Specification 4.10.1.B requires that leak testing be performed "...after each partial or complete replacement of the... charcoal adsorber bank.' Provide a commitment to conduct this leak testino after reinstallation of the carbon filter trays which are removed in accordance with the procedures (STP 10G3A) for conducting air / aerosol mixing uniformity tests.

Response: As described in our previous submittal (January 13, 1988, Question 2), STP 1063 A&B were performed on July 31, 1987. Subsequently, SPs 618 A&B were performed to test the charcoal to ensure that the trays were properly reinetalled. STP 1063 was performed for this restart effort t , is not expected to be repeated. As discussed previousl,, Rancho Seco Technical Specification 4.10.1.B requires the filter systcha be:

Demonstrated operable at least once per refueling interval, or once every 18 months, whichever occurs first, or after each partial or complete replacemant of the HEPA filter bank or charcoal adsorber bank, or following painting, fire, or chemical release in the operating air makeup system, or after any structural maintenance on the HEPA filter or charcoal adsorber housing.

The Technical Specifications provide assurance that testing will be performed, when required, to determine the proper operation of the filter system.

GCA 88-101 Attachment 1 Page 4 of 11 CR/TSC UVAC INSPFCTION QUESTION / RESPONSE Question 3: Clarify how procedure I.044, which "checks the probe sensitivity for chlorine concentration by using an approximately 10 ppm standard calibratic o gas, "is used to verify that the detectors are capable of detecting a chlorine concentration of 5 ppm are per R.G. 1.95 and how this relates to the use of I.045 to "check the alarm setpoint of 1 p?m."

Question 7: The staff is unable to conclude, based on information received to date, that reasonable assurance has been provided that the control room operators would be adequately protected against a chlorine gas release from the chlorine storage building area. Such a release could reach the control room air intakes but by-pass the "semi-remote" current location of the chlorine detectors considering the intake air flow rates (normal and -

radiation protection modes) and assured maximum inleakage rates. Provide additional assurance to support the existing chlorine detector location, or commit to a proposed schedule for evaluating alternative designs and implementing an appropriate design modification to provide further chlorine gas protection, during which time clearly adequate protection is provided including, if appropriate, the absence of such potential chlorine release cources from the site.

Response: Currently, gaseous chlorine has been removed from the site and sodium hypochlorite is being used in the water systems. Thus, the concern of a potential chlorine release is not presently applicable to Rancho Seco.

Evaluations are in process to determine the need for gaseous chlorine on site. If, upon completion of the study, gaseous chlorine is determined to be necessary, the District will address its impact on the CR/TSC and obtain NRC concurrence prior to bringing the gas on site.

GCA 88-101 Attachment 1 Page 5 of 11 CR/TSC HVAC INSPECTION QUESTION /RES PONSE Question 4: Clarify how plant security's procedures for approving opening of the control room exit leading directly to the outside of the building provides assurance that control room habitability is maintained during emergencies, or provide additional rationale to justify reliance on means other than administrative controls acting in conjunction with security to provide this assurance.

Response: The door which leads from the control room to tha turbins deck is designated as a security door. As such, it requires security be contacted and a continuous watch be posted while the door is open. This door can only be unlocked from the control room.

Since the door must be opened from the control room side and the operators are aware of the need for control room integrity in the event of an accident, they would ensure that it be closed and/or remain closed during any event requiring integrity. In addition, access to this door from the outside is restricted by another vital access door which leads to the transformer room directly adjacent to the control room.

Based on the above, the District considers there to be adequate controls on the door to prevent its opening during any event requiring control room integrity.

GCA 88-101 Attachment 1 Page 6 of 11 CR/TSC HVAC INSPECTION QUESTION / RESPONSE Question 5: Provide a commitment to perform periodic testing which will be relied on for indication of the leak tightness of the silicone sealant employed to limit air inleakage to the control roon. Provide a detailed description of the tests. This description may be provided subsequently with a scheduled commitment to do so at this time.

Response: As discussed in the inspection, the District will perform SP.84 A&B on a monthly basis as required by Technical Specifications. During performance of this test the control room pressure, relative to the outside air, is measured and documented. This data will be trended and reviewed for indications of pressure loss which could be indicative of a leak in the silicone sealant. This trending, in conjunction with the 18 month incpection of the sealant (Draft RT-HVS-Oll, Attachment 5), is considered adequate to provide assurance that any degradation of the sealant will be detected and replaced prior to its impacting the ability of the CR/TSC HVAC to perform its function.

Upon completion of the next fuel cycle, the District will provide the NRC with the trending results and the results of the inspection.

i GCA 88-101 Attachment 1 Page 7 of 11 CR/TSC HVAC INSPECTION QUESTION / RESPONSE Question 6: Provide the resolution, including schedules, and supporting rationale for the following licensee identified issues:

1) Automatic initiation of CR/TSC Essential Air System operation increases control room operator work load during certain critical plant operating pnases; and t

2) CR/TSC Essential HVAC controls and operating status indication in the Control Room are not adequate.

In addition, with reference to the above, provide rationale supporting the capability of the design to provide automatic initiation if needed, following manual shutdown of one or both trains of the Essential HVAC :

System.

Response: The automatic initiation of the CR/TSC on an ESFAS signal has been removed from the system. Automatic actuation of this system will now occur only on a toxic, high temperature or radiation signal. With respect to the control room indication, the staff was able to witness the operation of the system and to observe the system data available to the operators via IDADS. The additional information provided on IDADS in conjunction with the back lighted push button switches is sufficient to allow the operators to safely operate the CR/TSC system.

The operation of the CR/TSC essent!al HVAC is from the control room via a momentary contact back lit switch.

In the event of an auto start from either the toxic or radiation detectors, the switches will light indicating what initiated the start (i.e., toxic or radiation).

The operator has the ability to stop either unit on automatic initiation as long as the temperature within the control room is acceptable. If the temperature is above the pre-set limit, the essential units cannot be ,

i shut down. If the operator pushes the normal reset button, the unit will be stopped if the temperature l limit is satisfied, and reset for automatic actuation from any signal. The essential unit isolation /stop button will stop the unit (assuming acceptable temperatures) and only automatically actuate on high temperature. The control system provides the operator with flexibility in operation while providing assurance that the control room environment will be adequately maintained.

Question 8: a) R.G.,1;52 provides that a'93% removal efficiency (5% penetration) for organic iodide can be assigned for a'J-inch charcoal adsorber bed if the laborhtory tests show n"penetration of 1% or less.

This norresponds to a "safety factor" of 5 or greal'hb..-The Rancho Seco Technical Specifications provide fbe an assigned 90% removal efficiency (10%

penetration) for each of the 2-inch beds if the laboratory tests show penetrations of 5% or less.

This corresponds to a "safety factor" of 2 or greater. Justify this apparer.E discrepancy, b) Clarify the applicability of the discussion in your January 13, 1988 subr.ittal regarding statistical analyses of laboratory, testing criteria.

Response: a) Attachment 6 provides a detailed discussion and justification for the charcoal efficiency assumed for the CP/TSC VVAC.

QUESTION / RESPONSE Question 9: Provide a dose evaluation for all potential release points other than those identified in your response (e.g., ground level auxiliary building exhaust), or provide rationale for concluding that calculated doses for the identified potential release points exceed the doses that would be calculated for the other release points.

Response: As described during the inspection, the Ground Level Auxiliary Building Exhaust System draws from the containment penetration area (grade) and the HVAC equipment room (+20) passes through a HEPA and charcoal filter prior to being exhausted. Currently, all '

containment leakage is assumed to leak from the containment directly to the intake without decay or filtration. Had the leakage been assumed to pass through this exhaust system decay and filtration could be assumed thus reducing the dose impact.

In our January 13, 1988 submittal (Question 12), we provided source terms assumed in the dose analysis.

These source terms are the major contributors to the post accident dose and all other sources are considered negligible. The District considers the source terms assumed in the dose analysis to be acceptable.

GCA 88-101 Attachment 1 Page 11 of 11 CR/TSC HVAC INSPECTION QUESTION / RESPONSE Question 11: Justify reliance on the non-safety related IDADS computer system for HVAC equipment status monitoring ,

during emergencies considering the nature of its power supplies.

Responce: As discussed during the inspection, the information provided to IDADS is via the same data acquisition system used by the Class 1 SPDS. Only IDADS, which displays the data, is non-Class 1. Attachment 4 contains a figure showing the power supply to IDADS.

This figure indicates that IDADS has redundant non-1E power supplies. The preferred supply is through a battery backed, diesel generator supplied source.

Alternate power is available through an automatic transfer static switch.

As a result, we expect that IDADS will provide highly reliable indication of the CR/TSC HVAC parameters.

. . Attachment 2 Page 1 of 36 CONTROL ROOM /TSC FIIN BALANCE RESULTS 2/8/88 - 2/10/88 As indicated by the flow balance data in your possession and dated 2/2/88 -

2/3/88, several flow readings were out of specification and addressed via Nonconforming Report (NCR) 7588. In the process of evaluating systen heat loads to provide a disposition on the NCR 7588 items, Design Engineering received new, lower design value heat loads from the I&C Department for the Control Room area which justified the establishment of new flow balance criteria to increase required computer room flows and decrease Control Room flows.

The attached data provide the results of the final balancing ef fort. The values measured show considerable improvement in the number and magnitude of out-of-specification readings. In most cases, the deficiencies tend to cancel one another.

The end result of this new and final balancing ef fort provided more uniform positive pressures throughout the envelope, higher actual flows to improve overall heat removal capability of the system and fewer out-of-specification values without compensating effects within the same local air space. An explanation for each out-of-specification reading follows.

Item 1: Low Control Room return flow at traverse B4 in toxic mode.

Discussion: Although this value is <10% of design, it is 92% of the measured Control Room supply.

Item 2: Low Control Room return flow at traverse A4 in RAD /HI temp Discussion:

mod e .

One or both of the A2/A4 traverses must be considered suspect

[

as the large disparity cannot be substantiated by the accurately measured (micromanometer) positive pressure in the CR/TSC envelope with the makeup flow of 878 CFM measured with good confidence.

Item 3: Low flow assistant Shif t Supervisor office - both trains, both mod e s .

Discussion: Design Engineering has given tacit approval of the acceptability of these values.

Item 4: Low flow kitchen large register - both trains, both modes.

Discussien: Design Engineering has indicated that a total kitchen supply flow of 950 CFM was more than adequate and that an actual flow of approximately 800 CFM should be sufficient.

Item 5: High flev computer room register CD-338 B train, toxic mode Discussion: CD-3 38-3, -4, -5 all discharge into the same local area. The total flow from these three registers is still 99.4% in this condition. (i.e., 5569 CFM actual vs. 5600 design)

Attachment 6 Page 1 of 5 l

] ISSUE: Technical Justification for assum!.ng 90 percent removal efficiency by Rancho Seco charcoal adsorbers.

DISCUSSION: The charcoal adsorbent used in the Rancho Seco essential HVAC system is purchased from Nuclear Consulting Services, Inc. and bears the trade name NUSORB KITEG II. It is a coconut shell based activatedcarbon,co-impregngggdwithiodinesaltsandtertiaryamines.

The adsorbent is tested for ICH3 penetration at 30 C0 and 95%

, relative humidity in accordance with Technical Specification 4.10.

Such tests are performed: .

1. At the time of adsorbent manufacture.

{

4

2. At the time the charcoal is received at Rancho Seco (receipt may follow manufacture by up to 5 years, since the manufacturer's shelf life for the product is 5 years (1).

3. At periodic intervals after the adsorbent has been placed into <

j service.

Ratesting of in-service charcoal 0 for organic and elemental iodine removal efficiency at 30 C, 95% relative humidity is required by Technical Specification 4.10:

1. At 18 month intervals or each refueling outage, whichever is i

shorter; or

2. After the adsorbont has accumulated 720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months of active service j since the previous test; or

3. Whenever the adsorbent may have been exposed to an atmospheric !

contaminant having the potential to significantly impair the iodine removal efficiency of the bed (e.g., fire, paint or j solvent fumes, chemicals such as chlorine).

g :The frequency of successive laboratory tests on in-service adsorbent

iodine removal efficiencies is dictated by whichever of the three a

preceding Technical Specification conditions produces the shortest time interval. Normally, the adsorbent will incur 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months of active service

per month during mandatory testing of the essential HVAC system, or

approximately 18 hours2.083333e-4 days 0.005 hours 2.97619e-5 weeks 6.849e-6 months of active service between successive refueling j outages. The Rancho Seco adsorbers have been operated continuously for 720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months (30 days), St which time charcoal was retested, found to exhibit less than 1% 131ICH3 penetration at 30 0C, 95% relative humidity, and returned to service.

Attachment 6 Page 2 of 5 It is known that the organic and elemental iodine retention efficiencies of charcoal adsorbents degrade over time because of permeation of the bed by atmospheric pollutants present in ambient air.

The rate of degradation is greatest when ambient air is actively forced through the adsorber and bed. This ' weathering' phenomenon has been '

studied in detail by V. R. Dietz of the Naval Research Laboratory under contract to the U. S. Nuclear Regulatory Commission. The results are ;

reported in NUREG/CR-2112, NRL Memo Report 4516, Effects of Weathering on Impregnated Charcoal Performance (2). The study involved continuous exposure of eight commercial impregnated carbons to unmodified ambient air for different periods of up to 12 months at NRL in Washington, D.C. Two of the carbons were also exposed continuously to outside air at the Atmospheric Physics Facilities at the Argonne National Laboratory near Chicago, Illinois, and at the Air Pollution control District of Ventura County, California, Simi Valley Monitoring l Facility. After various durations of continuous exposure to ambient t air,laboratgrytestswereperformedontheweatheredadsorbentsto determine 1 ICH3 penetration.

The commercial carbons test involved three different classes of impregnants:

1. Potassium iodide with or without elemental iodine (the so-called

'KI' group).

Iodide salts co-impregnated with tertiary amines (the so-called i

' KI + TEDA' group) ; and, (3) tertiary amines alone (the so-called

'5% TEDA' group'). Dietz (Ref.2, p.15) notes that the results of '

the study should be correlated with the properties of test carbons with particular impregnations, rather than with a particular manufacturer's product. Rancho Seco's NUSORB KITEG II is co-impregnated with iodine salts and tertiary amines, and thus !

l is a member of the 'KI + TEDA' group of adsorbents (1).

Pertinent findings of Dietz's study relating to the weathering behavior of 'KI', 'KI + TEDA', and '5% TEDA' impregnated carbons are as follows:

1. Commercial carbons containing tertiary amines (e.g., TEDA) in the i impregnation formula, after exposure to the common contaminants in 3 outdoor air (e.

penetrationofg31 SO2, NOx, ozone, hydrocarbons), exhibit less i i ICH3 than do carbons exposed similarly with only J potassium iodide and iodine as the impregnation agents.

2. 131ICH3 penetration as a measure of carbon filter performance rises rapidly in air flows greater than 70% relative humidity.

3. The observed influence of water vapor on the degradation of impregnated carbons correlates best with the dew point of the air flow. Dew points below 20 0 F promote good trapping efficiency.

4. Penetration of 131ICH3 is most affected by prevailing dewpoint temperature relative humidity of air passed through the adsorbent during the last several days of weathering prior to removal for testing.

5. The common ambient air contaminants (ozone, SO2 , NOx, and hydrocarbons) initially adversely affect the outermost (inlet) layer of carbon in a filter bed. The profile of the gradient along the line of flow is logarithmic with depth (Ref.2, p.17).

With increasing length of service, the contaminants migrate to lower depths. (Based on this behavior, Dietz (2) recommends that use of an additional replaceable carbon "guard bed" could extend the useful life of an impreg7ated carbon filter) .

6. Laboratory studies indicate that the interaction of ambient concentrations of ozone, sulfur dioxide, or in design basis control room dose calculations of the periodic in-service 131ICH3 laboratory test results substantiate 295% removal efficiency at 30 00, 95% relative humidity. The actual removal efficiency of an adsorbent bed exhibiting 5% 131ICH3 penatration at 30 0C, 95%

relative humidity will be higher than the assumed 90% removal efficiency for the following reasons:

a. The test conditions under which 131ICH3 penetration is measured (30 0C, 95% R.H.) are more severe than the adsorbent would see in actual service, since inlet air is heated to reduce the reintive humidity of incomina air to 70% or less.

Based on Item 3 in the preceding list, 131ICH3 penetration at 70% relative humidity is much lower then at 95% relative humidity. Thus, a test result of 5% penetration at 30 0C, 95%

RH ensures a greater than 95% removal efficiency of the >

adsorbent under actual operating conditions.

b.

BasedontheexcellentweatheringchayacteristicsofNUSORB KITEG II, the maximum degradation in 31ICH3 removal efficiency between successive laboratory tests required by Technical Specification 4.10 (i.e., 720 actual operating hours) would be from 95% to approximately 94.5% (see Figure 1 and the discussion in Item 9 above). This assumes that the adsorbent has not been exposed to a ' poison' in the interim, '

such as exposure to paint fumes. Technical Specification 4.10 ensures retest of 131ICH3 penetration if the bed is exposed to a potential poison.

c. Rancho seco adsorbers are two individual 2-inch thick beds in series. From Item 5 above, common ambient air contaminants adversely affect 131ICH3 retention capability logarithmically with bed depth. Each of the two banks of Rancho Seco adsorbers (in series) is tested individually. The first bed will effectively serve as a sacrificial ' guard bed' for the second bed. When the removal efficiency for the first bed reaches 95%, the efficiency for the second bed should be greater than 95%.

In summary, the assumed 90% removal efficiency for organic iodine by a single 2-inch adsorber bed when they tested the nitric oxides with impregnated carbons are of second order importance relative to the influence of water vapor and organic compounds.

7. Exposures of 'KI' group carbons to intermittent flows of outdoor air (as would occur if the essential HVAC system were only operated one hour per month) yield more penetration of 131ICH than continuous operations with the same total volume of air.3 r This is in contrast to the behavior of carbons of the 'KI + TEDA' and '5% TEDA' groups (NUSORB KITEG II carbon at Rancho Seco is a member of the 'KI +TEDA' group), in which the carbon appears to be stable under both continuous and intermittent operations.

8. Exposure times of two to four days to air flows of low relative humidity (130%) are required to restore the trapping efficiency lost by a previous exposure to air of high relative humidity. An exposure time of comparable duration to high relative humidity air is required to degrade the trapping efficiency of a carbon having a low water content. Prolonged exposures to air flows of high dew point can learl to a degradation that is non-reversible at ambient temperatures.

9. The overall removal efficiencies of weathered charcoals of the

'KI', 'KI + TEDA', and '5% TEDA' groups after exposure to ambient air at the three test locations show markedly different behavior.

Figure 1 (corresponding to Figure 14 of Reference (2]) illustrates the weathering behavior of the three groups. The 'KI + TEDA' group, reprosenting the group to which NUSORB KITEG II adsorbent l belongs, shows a relatively linear increase of 131ICH3 penetration l as a function of constant exposure to outdoor air, from less than '

O.5% at time O to approxilaately 6.5% at 12 months of continuous exposure. Starting at the time the ,

131ICH3 penetration first equals 5%, the total penetration after an additicnal active expcsure time of 720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months (this is the maximum duration of active exposure allowed by Technical l Specification 4.10) is approximately 5.5%, representing a 94.5%

removal officiency for a single 2-inch adsorber bed.

I Attachment 6 Page 5 of 5 Technical Specification 4.10 states that a 90% organic iodine removal efficiency will be assumed (for a single 2-inch adsorbent bed) based on a tested efficiency of 2 95% at 30 0C, 95% relative humidity. The reason cited above provides for conservative design basis accident calculations.
