1.0 PURPOSE AND SCOPE r

This modification is to

' l. Provide the ability to install a liquid radwaste treatment I system in the Chemical cleaning Building. This system is to be capable of processing miscellaneous waste from TMI-l and THI-2 d or water from the TMI-1 Condenser. The design requirements for .

i this system are found in Appendix A of this document. l 1

2. Provide the ability to incorporate the two tanks in the OTSG Chemical Cleaning Building (CCB) into the TMI liquid Radwaste 4
System. These tanks are designated as CC-T-1 and CC-T-2.
3. Provide cross connections on Evaporator Condensate Domineralisers WDL-K-3A/B to enable them to be used in series as well as parallel to polish evaporator distillate. The cross connections are to allow either domineralizer to be the lead bed.
4. Provide the ability to use the TMI-2 Processed Water Storage Tanks to store secondary water from the condenser during i refueling. The ability to process this water is also to be provided.

~

5. Provide the ability to receive and process OTSG draindown during refueling.
6. Provide ability to transfer water from the Clean Water Tank in

' the CCB to:

)

(a): the river for release, l

(b): the WECST's for release, or l (c): the Waste Evaporator Condensate Domineralizers for additional processing

7. Provide ability to transfer water from the WECST's to the CCB for additional storage or processing.

l The designations "EPICOR-II Building" and "0TSG Chemical Cleaning Building

^

(CCB)" refer to the same structure at different times in its history.

1.1 Purpose

. 1.1.1 THI-1 Radwaste 1

The TMI-l Miscellaneous Waste Evaporator is the normal method l

of liquid radwaste processing at TMI. This modification will reduce the radionuclides (except tritium) released to the river with the evaporator distillate. This modification will also provide the ability to place a treatment system in parallel with the Miscellaneous Waste Evaporator to process the normal liquid radwaste from TMI-1, if required.

- 1.1.2 TMI-l Condensate'(refueling) l A significant fraction of the liquid activity released by TMI l

is through the secondary side during refueling. The activity

concentration is low due to the large volume associated with secondary side release. This modification will allow the secondary side water to be contained for processing before reuse in the plant or release to the environment. Ultimate release to the environment is important to the plant in that it provides for tritium control.

I 1.1.3 TMI-l condensate (abnormal)

In the event of a primary-to-oecondary system leak in excess i

of that which can be processed by ordinary means, the plant  !

4 will have to be shut down and the condensate system l decontaminated. This modification will allow the condensate .

system to- be processed through a portable treatment system l

! once the condensate temperature is lowered to acceptable .

j levels. l

! 1.1.4 THI-2 Radweste ,

q.

' Now that THI-2 has entered PDMS (Post Defueling Monitored

! Storage), there should only be minimal rainwater inleakage to be processed. This liquid must be processed, as necessary.

l Processing should be in equipment located either on the Unit I side or in the CCB.

! 1.2 Scope s

The piping around the Evaporator Condensate Domineralizers will be

. modified to enable either domineraliser to be the lead bed in a j series configuration. Currently the beds can only be operated

{ singly or in parallel.

The EPICOR-II system has been removed from the CCB. In its place will be provided the ability to install a rented multi-bed j

si'uiceable pressurised domineraliser system or other treatment l 1

system. Any domineraliser system will have facilities for a burial j liner /MIC to receive spent resin from the domineralizers. It will also have provisions to enable the burial liner /MIC to be dewatered Shielding will be provided for the domineralizers and j remotely.

spent resin liner / HIC. Controls, power, and monitoring / alarms for 7

i building operation are to be moved from the current EPICOR control shack and isolated areas to the office area and/or the messantne in 2

the CC3. Controls for a rented domineraliser system will be located in accordance with the needs of the system.

l Numerous pipe connections will be required. some pipe connections and isolations will be made in the TMI-2 Auxiliary Building in order j to simplify pipe runs. A pipe connection will be required in the TMI-l Auxiliary Building between the clean water return line and .the

' pipe leading to the TMI-l Waste Evaporator Condensate Test Tanks. }

~

j Three flanges or pipe cape in the TMI-l Turbine Building will be j modified to enable hose connections for condensate system cleanup.

4.1.6.1 " Normal" Peed If a temporary treatment unit is used, the normal feed to the I system from both TMI-l and TMI-2 is displayed on Drawing 3E-232-21-001, sheet 3. Liquid radweste from -the TMI-1 Miscellaneous Waste storage Tank (1-NDL-T-2) would be pumped by the TMI-l Miscellaneous Waste Transfer Pumps (1-WDL-P-7A/B) to the of f-spec Tank in the CCB or to the THI-2 Miscellaneous 3

i Waste Moldup Tank (2-WDL-T-2) where it would mix with any 1 water collected from TMI-2 sumps. Prom there, the mixture would be pumped to the Radwaste Domineraliser Building by the TMI-2 Miscellaneous Waste Tank Pumps (2-WDL-P-6A/B). These flow path needs can be met by the existing pumps. Part of the i

i original design bases for the 1-WDL-P-7A/B pumps wac to be l able to transfer water from the TMI-l Miscellaneous Waste Tank I i

to the TMI-2 Miscellaneous Waste Tank. The 2-WDL-P-6A/B Pumps l had previously transferred water from 2-WDL-T-2 to the EPICOR-j II system.

f 4.1.6.2 Plant shutdown OTs0 draindown would be pumped by the Powdex sump Pumps to a PWsT or to CC-T-1 for processing. Condenser water would be transferred to a PWST for processing before either being l

a released overboard or returned to the plant for reuse.

4.1.6.3 "Absormal" Peed Abnormal feed would consist of processing TMI-1 condensate l

following a primary-to-secondary leak in excess of that which can safely be processed by the existing TMI-1 Condensate

!- Powdex system. This flowpath is shown on Drawing 3E-232 ;

00, sheet 1. A portable pump connected by home to the new

' hose connection off the suction header for the condensate Pumps (00-P-1A/5/C) would discharge to the new hose connection

' on the portion of the 10-inch Chemical Cleaning line that i

extends to the Domineralleer Building. Untreated water would P

not be transferred to the PWST's.

4.1.7 Air will remain available to the THI-2 air operated valves j associated with the waste transfer.

4.2 Ceafiguration and Essential Peatures 4.2.1 The Clean Water and off specification Water Receiving Tanks 1 are the same as were used for the EPICOR-II system.

}

l 4.2.2 The control Room for the CCs is located in the offices There - is a connecting doorway i

attached to the Building.

between the control Room and the Building so an operator may 90 from one to the other without exiting the structure.

2 substation USS 2-33 located on the messanine floor at  ;

elevation 305' in the southeast corner of the TMI-2 Turbine Building. 480V power from Uss 2-33 is supplied to MCC 2-33A i currently located inside the EPICOR-II Control Shack. As part l i of PDMS, this will be repowered from Unit substation 2-32 in the Auxiliary Building at elevation 328'. The MCC in the

! EPICOR shack will have to be relocated to the new CCB control

' room.  ;

4.7.3 The CCS NVAC system f an and heaters, the transfer pump ( ALC-P- I i

5), building sump pump, the 20 ton hoist, agitators / mixers,  !

MOVs, and the new transfer pump are powered from MCC-2-33A.

A 480-120/208 VAC, 25 KVA transformer, supplied from MCC 2-33A, supplies all other system electrical loads in the CCB 4

from power panel MP 2-33A. This one-line configuration may i remain although the equipment must be moved to the CCB -

Page 10 of 22 l 4.9 Enviremmental Conditions i

4.9.1 Atmospheric conditions in the CCB 4.9.1.1 The highest and lowest recorded outside temperatures

' t in the area are 104 F and -14 F, respectively (Section 2.5.2 of the updated FSAR dated 7/90). The minimum inside temperature for the CCB is to be 40F to provide a margin against freezing. There is no maximum limitation.

4.9.1.2 Mumidity may range from 40 percent to 100 percent as i

determined by atmospheric conditions.  :

' 4.9.1.3 The CCB will continue to be serviced by the existing filtered air system currently in effect.

4.9.2 Flood Conditions 1 . 4.9.2.1 The CCB is protected from flood by being within the  !

site dike system.

4.9.3 Seismic conditions 4.9.3.1 According to the Section 1.3.1.7 of the system Description for BPICOR-II (Reference 2.5.1), the CCB has a seismic bathtub. The building, therefore, provides the

, ( seismic requirements of Regulatory Guide 1.143.

d 4:

4.9.3.2 Radwaste piping for this system shall either be l seismically evaluated and constructed or the lack of inherent seismic protection shall be compensated for by locating the

' piping in a structure with seismic bathtub or by placing the process pipe in a guard pipe. Allowable deviations to this criterion ares

1. Cleaned processed water return pipe from the Radwaste

, Processing Unit need not be supported to retain pressure integrity in the event of an earthquake. Reg. Guide

1.143 (Reference 2.2.2) would normally require this .
However, Section B of the Reg Guide states that the
i. purpose of the Guide is to " provide reasonable assurance that... radioactive waste management... systems are designed, constructed, installed, and tested of a level commensurate with the need to protect the health and safety of the public and plant operating personnel."

Use of non-seismic design is acceptable because the radiological concentration of this liquid is minimal as the water is slated for release to the environment in accordance with plant procedures.

2. The pipe set aside to transport contaminated condensate to the CCB, if necessary, is to be supported as Seismic III on the grounds that it will be rarely, if ever, used

' and it is to transfer water from the Turbine Building which, itself, is not a seismic structure.

l l

l l

l MDD-T1-232-5 DIVl/2 '

Rev. 2 May 25, 1995 Page 11 of 22 i 3. Piping for the purpose of transferring condensate to the PWST system will be a combination of existing pipe and some new interconnecting pipe. The existing piping will remain supported as is. New piping will be supported as l j

Seismic III. This is acceptable since the water to be '

transferred by this piping is currently sent to the i river via the Industrial Waste System. j 4.9.4 other Natural Phenomena 4.9.4.1 The upper, non seismic, portion of the CCB is not protected against the natural phenomena, as mentioned in 10CFR50, Appendix A (Reference 2.1.2), criterion 2. This is acceptable in that the temporary radwaste processing system will not perform a Nuclear Safety Related function.

i 4.9.5 Lichtina l

4.9.5.1 Lighting within the CCB shall be in compliance ,

with the TMI-l lighting requirements.

2 4.10 Radiological conditions ,

4.10.1 All systems are to be operated and maintained in such a manner as to maintain exposures to plant personnel to levels which are "as low as is reasonably achievable",

6.1.1 The instructions for initial fill, startup, normal operation, shutdown, draining, and refilling of the modified Evaporator

  1. Condensate Domineralizer subsystem will come from the operations department. ,

6.1.2 The instructions for initial fill, startup, normal operation, f 1

shutdown, draining, and refilling of any rented radwaste processing system will come from the system supplier af ter the  ;

' contract for the system has been bid and lot. l 6.2 Infrequent operations The only infrequent operation of the system should be the processing of secondary side condensate. System configuration for this evolution is to be standardized in procedures l 6.3 Transiest Operations

. Transient operations are not expected for this system other than for normal startup and shutdown.

7.0 C.JUAI.TY EVENTS AND REOCVERY 7.1 Castalty Rvests 7.1.1 Loss of coolina

There is no process cooling for this system. Therefore, loss

' of cooling is not considered a casualty event.

7.1.2 system Leakaos and Ruotures i

With the minor exception of a small section of piping discussed above, the Evaporator Condensate Domineralizer System and any rented domineralizer system are to be housed within the confines of structures that are protected by seismic " bathtubs". The portion of the overall system which involves the PWST system will handis water that currently is released to the river through the Industrial Waste System.

4, Therefore, leaks and ruptures are not an item of concern for

, the general public.

l 7.1.3 Minh Radiation Level Radiation monitors are to be strategically located within the CCE. Existing alarms on the Control Snack panel shall be moved to the new panel in the CCB.

7.1.4 Fires and Chemical Reactions Fire detectors are strategically located within the CCB. The fire alare panel in the Control Shack will be moved to the new CCB Control Room area.

l

MDD-T1-232-5 DIV1/2 Rev. 2 May 25, 1995 Page 20 of 22 7.1.5 Abnormal Flow Abnormal flow to any temporary treatment system, whether too rapid or too slow, will be detected by the system control circuitry and will automatically shut down and isolate the system.

7.1.6 Abnormal Chemistry If feedwater chemistry to any rented radwaste treatment system becomes abnormal enough to endanger system operation, the System is to be secured and the water processed through the Miscellaneous Waste Evaporator.

7.1.7 Unit Trin operation of radwaste systems is independent of reactor operation. Therefore, Unit Trip has no ef fect on operation of

. any portion of this modification.

7.1.8 System. e - nent. or Control Malfunction This f actor cannot be evaluated for a rented treatment system until the contract for the system is bid and let.

The modification around the Evaporator Condensate Domineralisers consists of pipe and hand operated valves. The potential for failure is minimal and would be covered in standard operating procedures.

7.1.9 Loss of voltaae Loss of voltage would cause any rented system to shut down once the voltage becomes such that process control would be jeopardized.

7.2 Design Features to Mitigate Effects of Casualty Events This f actor will be evaluated after the contract for a rented treatment system is bid and let 7.3 Recovery Procedures Procedures will be required to recover from spills and dewatering difficulties. These procedures will be required to be developed by Operations.

l 8.0 MAINTENANCE 8.1 Preventative maintenance procedures shall be in place for all cwponents including those associated with rented equipment.
