5.2-10 AMENDMENT 19 - NOVEMBER 1993

I 5.3.1.3 Remedial Decontamination Activities In the event that changing conditions are indicated, an evaluation will be performed as to the need for, and fonn of, corrective action to be taken. In general, those areas requiring routine access j

such as hallways and corridors will be maintained at the decontamination endpoints. All other i

areas will be assessed on a case-by-case basis with the deciding factors being the area's impact:

on personnel exposum and the possibility of a release to the environment. The Unit 2 PDMS organization will be staffed to pmvide the capability to take corrective action or call upon additional resources necessary to take cormctive action.

5.3.2 RADIOLOGICAL CONDITIONS AT BEGINNING OF PDMS i

Table 5.3-1 lists the specific radiological goals for the TMI-2 Reactor Building and the corresponding radiological conditions as of the most current radiological surveys existing in -

September 1992. The RB radiological conditions listed in Table 5.3-1 apply to general area j

access and do not represent maximum levels. These data were compiled in the manner described -

in Section 5.3.1.1.

Table 5.3-2 li,ts the equivalent infonnation for the AFHB as of November 1993.

1 l

Table 5.3-3 provides a summary of the mdiological conditions for the balance-of-plant areas not

]

covered by Tables 5.3-1 and 5.3-2.

I 5.3.2.1 Surface Contamination At Beginning Of PDMS To establish a baseline at the beginning of PDMS, the radioactivity present as surface contamination in various amas of the facility has been evaluated. This information serves as an initial reference for the evaluation of any future activities in the respective ~ areas.

In order to appraise the radioactivity pmsent as loose surface contamination upon entry into PDMS, an analytical model was constructed utilizing available loose surface contamination data, generalized waste stream isotopic distributions and estimates of surface area. This infonnation is fonnatted in a manner similar to the general area dose ate and loose surface contamination data presented in Tables 5.3-1,5.3-2, and 5.3-3. Only surface contamination was considered; fixed contamination or contamination intemal to piping systems or equipment was omitted. The genemlized waste streams or distribution of principal isotopes am referenced on each of the tables.

Table 5.3-4 lists the data obtained from the analytical model described above for the TMI-2 Reactor Building. Table 5.3-5 lists the equivalent data for the AFHB and Table 5.3-6 pmvides

)

a timilar summary for the balance-of-plant areas. All of the calculations of the quantities of i-curies listed are based on the specific decontamination goals given on Tables 5.2-2 and 5.2-3.

5.3-21 AMENDMENT 19 - NOVEMBER 1993

7.2.3.1.2

System Description

i The WDL system is designed to receive liquids from the Auxiliary and Fuel Handling Buildings, assoned equipment in these buildings, and frpm the Containment sump. This system has the capability to retain waste liquids for mdioactive decay, sampling, filtering, or tmnsfeiring liquids i

for disposal. During the TMI-2 cleanup, the capability to send water from the Miscellaneous Waste Holdup Tank (MWHT) to EPICOR II was added. The PDMS configuration is shown on I

Figures 7.2-8 and 7.2-9.

Liquid waste sources from the AFHB and Containment include tank drains, vents, fdter drains, flush line drains, and floor drains. Rain water inleakage into the AFHB also accumulates in the Auxiliary Building sump.

The WDL components that will be utilized during PDMS include:

MWHT (WDL-T-2) - This 19,518 gallon capacity, stainless steel, horizontal tank a.

is currently tied into the EPICOR II system to pmvide the waste water feed for EPICOR II. It collects water from the operable sumps, which are preferentially l

lined up to it. The tank has redundant inlet fdters (WDL-F-8A & B) to partially clean up the influent.

b.

Sumps - The Containment Basement and Auxiliary Building sumps are lined with stainless steel. I_cVel ir.dication _will be maintained for the Auxiliary Building Sump and Containment Basement.

t c.

Sump pumps - The Auxiliary Building sump has dual pumps that operate manually as needed. When in operation, they are operated alternately to equalize mn times.

The Reactor Building Spray and DHPs sumps (four total) have a single pump that operates manually as needed. Capacities of the pumps are as follows: Auxiliary Building sump pumps - 100 gpm; Reactor Building Spray and DHR sump pumps

- 50 gpm. Timse pumps will be maintained operational and placed in a manual control mode.

d.

ABST (WDIeT-5) - This 3,085 gallon capacity, stainless steel, horizontal tank and its associated equipment will be maintained operational as a backup in case the MWHT is not available for extended periods.

Selected WDL tanks (e.g., the MWHT and ABST) have been isolated from the Radwaste Disposal Gas System and vented to the Auxiliary Building atmosphere by disconnecting and opening either the vent header connection, relief valve, or rupture disc. Canridge type HEPA fdters are installed on the selected opening (s) to protect against airborne releases fmm these tanks.

During PDMS, the Auxiliary Building Ventilation System is not required for waste water transfer operations in the Auxiliary Building. These transfer operations do not pose an airborne problem since any airborne contaminants would be released from the water prior to entering the MWHT or the ABST. Contaminants stirred up in the MWHT or ABST will be contained by the HEPA filters installed on these WDL tanks.

a.,

The Containment Sump and Sump Pumps are in an undetermined condition. Ikause the

{

existing plant sump pumps WDL-P-2A and 2B have not been refurbished, an alternate flow path

)

will be utilized to drain down the RB basement floor. A tie-in to the WDL system has been provided outside of penetration R-593. This tie-in runs from the decay heat removal pump suction header isolation valve test connection to the RB spray pump room sump.

l l

7.2.3.1.3 Evaluation l

Because a majority of plant systems are deactivated, have been drained, and placed in a layup

{

condition, there are a limited number of activities that can generate liquid waste during PDMS.

Liquid waste in the mmaining systems and accumulated water inleakage will be adequately handled by periodic batch pmcessing using the operational ponions of the WDL system through EPICOR II and discharged via approved pathways. This ensures minimum exposure to plant personnel and minimizes elcases to the environment in accordance with 10 CFR 20 and 50.

l 7.2.3.2 Sump Pump Discharge and Miscellaneous Sumps System l

7.2.3.2.1 PDMS Function h

There are a number of sumps in TMI-2 that will be maintained in an operational condition during PDMS. The various sumps and their locations are listed in Table 7.2-3.

l Maintaining the various building sumps operational assures that water buildup does not cause I

adverse localized flooding. These sumps will contain water that is either clean or slightly radioactive. Clean water is presently routed to the Industrial Waste Treatment System (IWTS).

Radioactive water requiring processing will be muted to EPICOR II* and discharged via

)

approved pathways; slightly radioactive water will be pumped to the IWTS and released in accordance with 10 CFR 20,10 CFR 50 and NPDES regulations. The discharge from the IWTS is monitored for radiation in accordance with the ODCM.

l i

l The EPICOR II System will be used after the TMI-l Condition of Operation prohibiting L

the transfer of Unit 2 liquid to Unit 1 is rescinded.

Do all containment and auxiliary building vents discharge to the station vent? Will all vents be closed during those times that the ventilation system is not operating? If not, will they be monitored?

1

RESPONSE

All Containment and Auxiliary Building vents discharge to the station vent.

The vents for the Auxiliary and Fuel Handling Buildings (AFHB) will not be closed during periods that the ventilation is not operating. This will allow pressure equalization with the environment through a filtered pathway. The Reactor Building (RB) will be vented through a filtered breather to the Auxiliary Building whi)i the RB purge is secured.

The station vent will not be monitored by real time sampling during periods when the ventilation is not operating, First of all, sampling would not be representative during periods of very low flow and secondly the potential for a significant release to the environment u very small.

The RB has larger quantities of residual contamination available to release than the AFHB. A sample fiher paper installed downstream of the RB breather HEPA will be removed and assayed at least semi-annually to evaluate any release to the l

environment during periods ofinactivity. If the RB releases are very small, which they are expected to be, then the Auxiliary Building releases would be even smaller. In any event, the releases to the environment during periods ofinactivity are expected to be insignificant because there is no motive force for forting the

[

radioactivity through the ventilation system to the environment.

1 Off-normal events which could provide a motive force, such as a fire, have.

previously been studied to determine the potential releases to the environment fmm -

the AFHB. These studies have shown that the off-site doses resulting from off-normal events would result in a dow of less than 10 millirem to the maximum exposed individual assuming no filtration.
