INTRODUCTION This report is a presentation of the data for the May thru August samples from Exhaust Systems located at the Three Mile Island Unit #2 Nuclear Plant.

The Systems aro:

1) Fuel Handling Building "A" Train AHF 10A
2) Fuel Handling Building "B" Train AHF 108
3) Auxilliary Building "A" Train AHF 14A
4) Auxilliary Building "B" Train AHF 148
5) Condenser Vacuum Pump
6) Supplementary Filter Train fh AM-1
7) Supplementary Filter Train #2 AM-2
8) Supplementary Filter Train #3 AM-3
9) Supplementary Filter Train #4 AM-4 for the Fuel Handling Building Trains and the Auxilliary Building Trains, bulk samples have been received. Moisture and pH analysis were performed on these samples por ASTM D2867-D for moisture and ASTM D1293 for pH.

Radioiodine removal efficiency tests at 30% RH, 250C and 95% RH and 250C were also performed on these samples per RDT M16-1T.

The Condenser Vacuum Pump and Supplementary Filter Train samples were sampling canisters. There was only enough sample to perform a 95% RH, 25"C radiciodine removal efficiency and activity analysis in June & July.

A complete cell has been received each month for the Fuel Handling Train "B", AHF 108, sample. Core samples are removed per NUCON Report 6MT611/04. Each layer of the core samples are analyzed for moisture and pH per their respective ASTM procedures. A composite sample is also taken and radiciodine removal efficiencies are performed at 30% RH, 250C and 95% RH, 25oC per RDT M16-1T October 1973.

Activity analyses are performed on all samples on a PGT IGW 7026 #601 Detector, Norland IND-Tech 5400 Analyzer.

II. RESULTS & DISCUSSUION The results are outlined in the following tables and graphs.

NOTE: The iodine efficiency test data in this report is from NUCON reports 6MT611/05, 06, 07 Rev 1 (which replacos NUCON 6MT611/07), 09 and 011. See these reports for the detailed radiciodine efficiency test parameters and rosults.

I NUC0W 6MT611/13 _12 - Many of the numbers represented are basically just numbers rather than data of actual value. This is due to poor sampling procedures and poor data logging by those taking and preparing the samples. The bulk samples weresent to NUCON in plastic bags. There is no data as to what cell, location in bank and at times what date taken noted on these bags. NUCON has been informed the bulk samples are taken by emptying a portion of a cell into a plastic bag and then taking a portion of that to be sent as the sample. The part of the cell that has been emptied is then refilled and the cell replaced into the adsorber bank. If this sample is not properly mixed then there is no homogeneous sample. If there is no homogeneous sample, then there is on reproducible data. The fuel Handling Building "B" Train AHF 108 cells that have arrived are not comparable. Tho June sample was NUCON NUCELL 821-L carbon type NUSORB KITEG Lot 024, fill Date 7 March 79. The July sample was MSA Cell #79-242, carbon Type 463563, Lot C-244, Fill Date May 79. There is no data on installation dates or location in bank.* These cells have different manufacturers' carbon in them and may have been installed in the banks at different times. There is no manner in which meaningful data can be taken from differing cells with no background data. The sample canister from the supplementary filter trains (AM-1 thru AM-4) are totally inadequate for a representative adsorbent sample from the installed bank. The inlet is 1/4" NPT and there is no detailed data on the length of the 1/4" inlet pipe. This does not allow for a representative air flow as compared to an actual Type II Adsorber. Appendix "A" discusses the requirements for adsorbent sampling. There are no reproducible serial number, installation date, sampling date, carbon type, or location informe. tion sent with them. Additionally the canisters rattle indicating insufficent fill, particularly for horizontal operationd There is data for the number of running days for May, June, and July for the supplementary filter trains. j 1May - 31May 79 13une - 293une79 303une - 313ul 79 Days Eff** Days Eff** Days Eff** Supp. Train # 1 29 No Sample 29 70.85 32

e NUCON 6MT611/-i 3 There is a hint of a trend for Supplementary Train #3 and Supplementary

  1. 4, but the first two trains are not explainable uith the data at hand.

There is no background information to make any explanations. The possible explanations of sampler location, inadequate samplers, carbon type, etc., cannot be supported due to this inadequate background information. The only sample that seems to have any reproducibility is the condenser vacuum pump system. The canister from this system has a two inch diameter inlet, There seems to be an order to the serial numbers of the canistors (May S/N 720540, June S/N 720541, July S/N 720544) and a r.arbon Lot Number AAF 0130. There is still no installation date for the canisters or the installation dates of the adsorbers in the bank or if the carbon in the canisters is the same as the carbon in the adsorbers. We have no sampler location information either. Recommendations to alleviate the labeling and sampling discrepancies are:

1) Diagram each adsorber bank, put serial numbers of each cell in appropriate blank and indicate when sampled.
2) Supply serial number, installation date, cell manufacturer, carbon manufacturer, filling date, carbon type and lot number for each cell in each bank.
3) When sending bulk sample from a Type II cell remove the fill port cover from one side of a tray, empty the whole side into a plastic bag, rofill that side of the tray and label the sampling date on the fill port cover. On the bag label the cell serial number, cell manufacturer, filling date, carbon manufacturer, carbon type and cell installation date. Then the next month repeat the procedure with the other side of the tray. Each cell will then provide two bulk samples.
4) Diagram canister sampler location, serialize canisters, blank off sample canister port after sampled, make sure carbon in canister is the same as the carbon in the bank (installation date, carbon manufacturer and type). Send four canisters per system.to allow sufficient sample for a full set of testing.
5) Use NUCON Procedure 34 (Appendix 2) when sampling a NUCON Test Tray Assembly.

III.

SUMMARY

Unless proper sampling is performed and sufficient detailed data is obtained and'provided on the samples sent,NUCON cannot properly analyse the performance of the carbon in the adsorber banks in the sampled systems. Based on carbon properties only an approximation is made on figures 2 thru 5 on the officiency trend for the primary systems.

ANSI /ASME N509 ANSI l509 Hov 1 . /79 0 as approved by the APPENDIT. A Rain Cowaittco CONAGT Rev. ( Sampling of Installed Adjorbents for Surveillance Testing . A. 1 SCOPE Provision shall be made to periodically remove a representative sample of adsorbent from an installed system for Surveillance Tests. A representative sample is defined as one that has experienced flow within + 20% of the average flow of the system (as confirmed The detailed means to by testing per'Section 8 of ANSI N510). achieve this is left to the designer of each system but detailed (either theoretical or empirical) shall be pre-supporting data sented to substantiate that the flow is representative and the sample is, therefore, representative of the entire adsorber bank.

n..

A. 2 DESIGN BASIS FOR SAMPLERS ~ ISince the sample shall be representative.it shall have experienced the same exposure to all contaminants'as the entire bed it repre-sents. To accomplish this it shall have experienced the same flow (+ 20%) for the same time. This criterion can be met only if the bed depth and pressure drop through a sampler section are the same as through the overall adsorber bank. All flow restrictions l must be taken into account when designing a sampler. Pipe stubs, valves, unions, fittings, elbows, nozzle effects and similar items or effects.all add pressure drop and tend to make a sampler non-representative. This standard does r.ot restrict any specific approach or hardware but stresses the flow criterion must be met. A. 3 GENERAL TYPES OF S iPLES (SAMPLERS) A. 3.1 Individual Samplers i A special adsorbent sample holder should be designed to hold adsorbent for testing. It shall be the same depth as the main bed, a minimum of 2" in diameter and in the same orientation as the main bed. If there is a guard bed it shall be duplicated for the sampler. The sampler shall be filled with adsorbent from the same lot and batch as the main bed. The guard bed, if any, shall be filled with adsorbent from the same. lot as the main bed. Each sampler shall have at least the following data permanently attached: Serial Number Adsorbent Lot and Batch Number Adsorbent Mfg. and Type Installation Date System Where Installed 56

Consideration should be given in the design to allow insertion of the sampicr into a laboratory test apparatus for determination of methyl iodido penetration without disturbing any of the adsorbent. ~ A. 3.2_ Test Tray Assemblics A Test Tray Assembly is an adsorber unit modified for provision for removal of a portion of the adsorbent (usually one eighth) with-out disturbing the remainder of the adsorbant. Its use is acceptable as an alternate to individual samplers dcscribed in Section A.,3.1 of this appendix for obtaining representative samples. When a test tray assembly is removed an entire section is emptied into a clean plastic container or bag, mixed to ensure uniformity, a sampic taken, and the section refilied with such makeup adsorbent as required. This makeup carbon shall meet the same requirements as the original adsorbent. The section sampled shali be marked to indicate when a sample was taken and the section number and position noted b~oth in the field test report and permanent plant records to ensure that this section is not used abain. _Jach cover plate shall be permanently marked with a unique identifi- _ cation symbol. Each test tray assembly shall have at Icast the following data permanently attached: Scrial Number Adsorbent Lot and Batch Number .o.. Adsorbent Mfg. and Type Installation Date ~ System Uhcrc Installed A. 3.3 Sampling by Adsorber Unit Removal As a further alternate, an entire. adsorber cell or bed may be removed to obtain a sampic. It shall be emptied into a cican plastic container of bag, the adsorbent mixed to ensure uniformity, a sampic taken, the cell refilled or replaced. If the unit is refilled it shall be marked as having been refilled and shall not be used for future samples. New or refilled units shall not be used for sampic$ since they are not representative of the adsorbent in the bank. O 57 .,,,,,_...._,n.-

a.,.a..~.-.-.._- ANSI /ASME H509 Rev/79 4 .6 ~ A, 3.4 Slotted-Tube Sampling por existing systems where the adsorbent bed is refilled in-place (Type III) a sample may be taken with a slotted-tube sampler. See ASTM E-300 for slotted-tube sampl~cr details and background. For future Type III systems, slotted-tube samplers shall not be used; rather, samplers as described in Section A.3.1 shall be employed. For systems uhere the adsorbent bed is 2" deep insert the slotted-tube sampler into the bed far enough to ensure that the sample will be taken from an area where flow is experienced by the ad-sorbent. For systems where the adsorbent bed is greater than 2" the position where the slotted-tube sampler is inserted into the bed is important. 5f a single sample representative of the entire bed is desired, ~ then use the slotted-tube sampler at an angle to pick-up sample from both the inlet and outlet faces of the bed. Do not use carbon from areas of no flow. 6 If separate samples from inlet and outlet faces are desired then n.: sample positions should be noted. These separate samples should

h not be mixed.

A composite efficiency may be required to be calculated ...for the bed if separated samples are taken. . ~.... : 58
