MEMORANDUM i

l Design EngineeringSection May 29,1991 MEU 91-999-C89 TO:

Allen Howe FROM:

Andre' S. Drake s

SUllJECn Follow-up to Questions Raised at Containment Sump Operability Meeting As you recall, a meeting was held on May 22,1991 to brief you on the work done in connection with the containment sump debris issue, and to answer your questions on the Unit 2 Operability Evaluation (Re NCR 11616). You raised two questions for which an answer was not immediately available. He following is meant to answer those questions.

1.

Could the " dirt" found in the containment sump be washed through the recirculation headers as a cohesive mass (i.e., slug) so that it causes the malfunction of a pump, or causes a valve to become clogged?

a I

As initially indicated during the meeting, a slug of" dirt" travelling down the recirculation header is not a credible event. He reasoning behind this is as follows:

The inspection of the recirculation headers for both Unit 1 and Unit 2 revealed that the dirt was spread out along the length of the pipe. He largest clumps were

, proximately the size of a dime, and these clumps were boric acid crystals which would have been reduced in size if not entirely dissolved during the minimum period of 36 minutes when it would have been exposed to water prior to the start of recirculation flow. Also, since the water fills the recirculation header for at least 36 minutes before the start of recirculation flow there is no current of significant strength which would wash the dirt along in its flow path thereby creating a slug of dirt. Finally, at this point the ratio of water to dirt is so high that the dirt would in effect go into solution, and would have no effect on the water being used for recirculation flow.

As a side note, one of the pump vendors had said that based on their experience with sluny lines a flow velocity of approximately 7 ft/sec is required to move a solid slug of significant size (5-10 lbs). Since the flow velocities in the 24" recirculation header would only be 2.6 ft/sec it i' not credible that a slug of dirt could be drawn into a pump even if one were to have existed.

l l

2.

What input data was used to calculate the flow velocities listed on page 2 of the Unit 2 Sump I

Debris Evaluation?

ne flow velocities through the recirculation headers are directly related to the flow rates j

through the IIPSI and CS pumps and the flow required for Auxiliary Feed. CE Windsor was supplied with the most recent IST Pump flow curves, and from this they measured the h

~ ',

s, 1

t maximum Containment Spray Pump Flow rate to be 2200 GPM, and the maximum HPSI pump Flow rate to be 650 GPM. It is noted that Chapter 6 of the FSAR lists the

(

containment recirculation flow rates for these pumps as 1630 GPM and 607 GPM respectively. Therefore, the flow velocities CE Windsor calculated will be higher, and hence more conservative, than the flow velocities calculated from the design basis parameters. The attached sheet is a sample hand calculation of how these flow velocities are calculated.

~ -. No. 2-89-83 provided a portable blower and eleohant trunk te direct the exhaust from the ECCS sump to the intake of the plant main vent. The inspectors reviewed the safety analysis that accompanied th? above temporary modification and concluded that the scope of the analysis was limited.to the consequences of leaving the blower j and ductwork in the ECCS pump room. DG&E could not produce an analysis to support the use of this flowpath as a method to vent j the containment. The Calvert Cliffs Final Safety Analysis Report (FSAR) does not. recognize the use of the containment and ECCS l sumps as a containment vent path. OI-36 was revised in 19'? ? to l allow using this vent

path, ye*

BG&E could not locate the supporting documentation that analyzed this method. The inspectors discussed this issue with the appropriate site staff and expressed concern that ventina containment via the sumps was not analyzed. BG&E aareed and prohibited using thin method until a safety analysis was performed. This analysis was approved on May ??, 1991, and concluded that ?????'??????????? In conjunction with this effort. the inspectors questioned 4:ompliance with the NUREG 0737 Item II.E.4.2, position 7, which required that containment vent isolation valves close on a hiah l radiation signal. Although MOV 5462 and MOV 5463 receive an automatic close signal from a safety injection actuation, they do not close on a high radiation signal. l 7'. 3 Debrimrinathe: Containment Emergency Sumps BG&E identified debris in the Unit 2 containment emergency sump (sump' and recirculation lines in January 1991 and upon furthe investigation. found a lesser quantity of similar debris in the Unit 1 sump and recirculation lines in February. NRC review of this issue was documented. in NRC Inspection Report 50-317/91-05 and 50-318/91-03. An unresolved item (50-317/310/91-03-02) I identified concerns that can be summarized as follows: ] . \\p+ 6 r 1. Foreion material exclusion and cleanliness controls were not uMj being adequately implemented as described in Quality 0 l Assurance Procedure No. ill " Plant Maintenance." paragraph

d. h 5.4 which states that maintenance orders must give specific Wg' instructions or reference specific procedures that specitf M

how special considerations such as cleanliness controls will g be implemented. Several examples of program weakness and some examples where the program was disrecarded were identified in the report. 0$T 1. 2. An operability assessment of the'/ emergency core coolino twa M system (ECCS) was not complete and needs to$be reviewed. Odda,. OM Yum dt,emN DG&E removed the debris and cleaned the sumps and recirculation AOT NN lines for both units. In March. a three inch wire was found in the Unit 2. sump during the performance of surveillance test procedure O-44-2 " Refueling Interval Containment Emergency Sumn Inspection." In May, a problem report was issued after BG8.E p [0 determined that the initial entry on January 25, 1991 into the l Unit 2 sump was made without adequate material and nersonne)

The Unit 2 evaluation was the most limitino since a greater quantity of debris was found. The evaluations indicated that some degradation of performance could be expected, but-that the safety functions would be performed. These evaluations adequately pddressed the. credible effects for the ingestion of de i the pumps and other system components. An intern-investigation of the effectiveness of cleanlinecs j controls and the results were presented to the Plant Operations i Safety Review Committee on April 15, 1991. This investication l concluded that many personnel who work in clean areas W not trained in clean atea requirements, that personnel dM not appreciate the importance of clean area requirements, and the procedures for cleanliness controls N unclear and confusing. The investigation recommended training improvements and revistons I to the procedures for cleanliness controls. This investigation was thorough and identified generic program concerns similar to those identified by.the NRC. l BG&E has taken actions to - address concerns with the. foreign materials exclusion and cleanliness controls program. An enclosure to prevent tha entry of foreign materials into the sump as been designed and approved for installation during outages. Revisions to procedures CCI 107 Revision J " System Cleanliness Criteria" and CCI 206 Revision I " Foreign Materials Controls" were implemented in March 1991. The procedures more effectively specify the foreign materials exclusion and cleanliness controls programt however some administrative and implementation problems have been ident fied by BG&E. The final root cause evaluation gt for the entry of foreign materials into the sumps was pending as d f getd the inspection' period closed. 1 Notwithstanding the actions taken by BG&E, the foreign material exclusion and cleanliness controls were not being adequately implemented. Concerns previously identified by BG&E were not adequately corrected an evidenced by coqtinued problems atter the _pd. issuance of a nonconformance report that tr encea several cleanliness control problems as indicators of program weakness. ( The presence of foreign materials in the sump and recirculation lines had the potential to degrade the performance of the safety injection and containment spray systems in the recirculation mode. In this mode, these sys.tems provide the long term emergency core cooling, residual heat removal, and containment atmosphere cleanup safety functions. Quality Assurance Procedure No. 14 " Plant Maintenance," paraqrnph 5.4 requires that maintenance i orders give specific instructions or reference specific procedures that specify how special considerations such as cleanliness controls will be implemented. The gagure to implement these controls during activities that affect quality cafety related systems is a violation of 10 CFR 50, Appendix b. Criterion V (S0-317/91-13-?? and 50-310/91-13-??). g . _ _. _.. ~ _ _ .,. ~ - -.

Description:

fp%g e 1000ML polyethylene bottle found inside U-2 Pressurizer l CONCERNS: 1 1. Removal of the bottle. ! l The bottle was removed and documented under MO #208-306-143A. k h 2. How bottle was left inside. Due to the lettering on the bottle, it can be assumed that it was associated with the Pressurizer Project. However,it is hard to determine how the bottle was left inside. There was more than one bottle of this sort used on the job, and at the job site during this work. The person performing the final closecut, aerformed a very specific and detailed inspection inside the pressurizer. Mowever, after he exited the pressurizer, a group ofindividuals removed scaffolding that was inside the pressurizer. I have not been able to find any further entries into the pressunzer or removal of the manway screen. There is the possibility that th'e bottle was inadvertently knocked in during removal of the scaffolding. i 3. Actions taken to ensure additional items were not left inside. After the bottle was removed, a camera and monitor was set up and lowered into the pressurizer. Only a paaer was found. CCI-1071, piece (approximately 3/4" dia.) of millipore filte at ?OSRC meeting 91-039 on 2/20/91 which allowed the filter paper to remain in the pressurizer due to the radiation hazard ifit were to be removed. 4. The potential safety significance is described below. A. The following is whatis known: 1. The low density polyethylene bottle is made of food grade resins, antioxidants and thermal stabilizers. The chemical make-up of these elements the NALGE Company considers proprietaryinformation WM

W 2. The bottle melts between 180 -250 F. t 3. The surge line extends into the pressurizer approximately 24" f and has a screen assembly over it and a solid hd on top ofit. 4. Chemistry deviations in chlorides and sulfates are addressed by .~ Pete Crimgan in his attached letter. il 5. Prior to forming the pressurizer bubble, the pressurizer is ( " solid"at 370 F. In this condition, the bottle would be in a "i melted / liquid state. Whether it would be a single mass, p! dispersed into droplets, float or sink is unknown. The NALGE d' Company and Plant Chemistry could not determine this. 4, B. Some possible events could be (these are hypothetical) {' 1. The plastic would float, disperse like an oil slick - with the l, pressurizer solid,if a PORV were to o 7 exposed to the internals of the PORV. pen, the plastic would But due to the heat,it l would probably not affect rescatmg. 1 J 2. The plastic would float, disperse like an oil slick - during f " drawing the bubble", while lowering the water level, the plastic would c ing to the walls of the pressurizer, but would return to the water due to the temperature of the pressurizer during operating, approximately 630 F. 3. The plastic would sink as a mass - the probability of entering the surge line is remote due to the lid over the surge line and the height of the surge line. It is more probable that the plastic f would settle to the bottom and possibly " plate out" on the pressurizer heater wells due to the temperature of the heaters. i i 1 4. The plastic would sink, as droplets disperse throughout the pressurizer - this stands the best chance of getting polyethylene throughout the RCS. Due to it sinking, it is doubtful that it woulc affect the CEDM's because of their height and low flow conditions. It is a possibility that the plastic would " plate out" on the T;el assemblies, however, it it were to " plate out", it most would most likely " plate out" on the pressurizer heaters before leaving the pressurizer. But, it is more probable that it would be cleaned up in the purification system. j 5. Adequacy of existing processes to ensure similar events will not occur in the future. Since the most likely cause of this event was a bottle inadvertently knocked in,

• the adequacy of our existing CCI-107 close out inspection, which found the bottle, is sufficient. To prevent any intentional tampering inside the pressurizer, the screen is locked in place, thus preventing removal.

Additionally, both CCI-107 and 2% are revised and are currently in the implementation phase. These revisions strengthen controls in this area. c r l RLF/jbt

SUBJECT:

Polyethelyne Bottle Decomposition If the polyethelyne bottle was left in the Unit 2 Pressurizer, the.following circumstances may occur: Decomoosition Products - the polyethelyne bottle will not totally decompose, but it will release organic compounds from a partial decomposition. These organics will not directly detrimentally affect the system integrity, but will cause an increase in the conductivity of the water, and may affect the purification ion exchanger. Depending on the level ofimpurities present, a chloride and /or sulfate spike will also result. Polyethelyne - the most serious consequence of the event would be the melting of the bottle material. Since the material will not decompose until extremely high temperatures, the polyethelyne will melt and stay in an organic liquid state. It may separate into small droplets the size of resin or it may stay as a single mass. This material may be transported around the system and have an array of effects. The most optimistic result would be the removal of the substance by the purification system. Under the worst circumstances,it would clog or adhere to vital key components such as CEDMs, pressurizer heaters, fuel assemblies, Steam Generator tube, or instrument tap-offs. It is impossible to accurately predict how this material would flow thru the system. In conclusion, it is doubtful that any significant chemical impurity degradation would result directly from this event, it is probable that the material itself would cause an impact on a system component. k GeneralSupervisor r
