Ad Entergy Indian Point NPP Dec 13, 2005 IPEC-CHM*-05-042 MEMORANDUM TO: R. LAVERA - Sr. HP/Chem Specialist FROM:

S. SANDIKE - Sr. HP/Chem Specialist

SUBJECT:

UPDATE TO INITIAL MONITORING WELL OFFSITE DOSE CALCULATION Chemistry memorandum IPEC-CHM-05-034 identified a technique and a dilution volume estimate for

-,,determining a bounding calculation for the Tritium and other isotopes leaving the unit 2 SFP and being released to the river via the bedrock (under the discharge canal and the normal dilution pathway). This earlier memo applied standard Reg Guide 1.109 modeling with the dilution volume consistent with the effected cross-sectional area of the Hudson, under which the H-3 was expected to escape to the river from the sediment. The basis for this early modeling was derived from original ODCM basis information, specifically, "Radio-ecological Studies of the Hudson River", from NYU and Dr. Paul Linsalata (1987).

Subsequent to issuance of the earlier memo, additional evaluations were conducted on site, and independently by Dr. John Hamawi of Entech Engineering. Dr. Hamawi was asked to perform two tasks:

1) Re-evaluate a more appropriate dilution term for this calculation, and 2) Independently perform a bounding olTsite dose calculation, using this dilution factor. In his report, Dr. Hamawi identified an earlier official calculation and reference to the FSAR to determine the volume of water equivalent to the volume of water passing by the plant (a typical 6-hour half-tidal cycle), during the same release interval identified in the Reg Guide 1.109 modeled release calculation. His report states:

The activity released during the entire quarter is further assumed to get released into the river during a single 6-hour half-tidal cycle, and to mix uniformly with the average water mass that traverses the Indian Point site during the same time interval. This dilution volume is equal to 5.495E+07 m3 (1.45E+010 gal) when there is no fresh-water inflow from the estuaries (from Calckulation IP3-CALC-RAD-00016, pg 45, based on the UFSAR). The scenario is equivalent to a slug of water, equal to 5.49E+07 m3, moving back and forth by the Indian Point site carrying the same concentration listed above for an entire quarter, without additional dilution.

Dr. Hamawi's dilution volume, then, for a bounding calculation of a release over a quarter was 1.45E+1 0 gallons. He! then applied this dilution to an original and approved code (AQUADOS) to determine the potential offsite dose. Site specific dose factors, source term, and exposure interval were supplied from the site Chemistry group. His findings attached are summarized below:

Case I (without the drinking-water pathway):

2.50E-05 mrem/quarter, adult total body 4.15E-05 mrem/quarter, child bone.

Case 2 (with the drinking-water pathway):

3. 77E-05 mrem/quarter, adult total body 6.94E-05 mrem/quarter, child bone.

The Chemistry group conducted an independent review of Dr. Hamawi's calculations using the sil:e's ODCM and implementing software. Once the dilution term had been decided, the dose calculaticn progressed according to standard Reg Guide 1.109 modeling, as follows:

The IPEC ODCM dose calculations above do NOT include added dose for the non-existent potable water pathway. Dr. Hamawi provided dose calculations both with and without this term for evaluation purposes, in light of the highly publicized potable water concern.

The independent dose comparison was nearly identical, as summarized below:

3. 59E-05

4. 13E-05 Dr. Hamawi's work was officially provided to ABS consulting for inclusion in their formal report.

These effoits will serve as a starting point to bound the offsite dose as a result of the loss of inventory from the Spent Fuel Pool, or the identified activity in site Monitoring Wells. These calculations were performed and verified to bound the offsite dose in communications to the NRC and the general public.

Since they define a worst-case scenario, use a conservative absence of routine dilution flow, and use an actual-s'u'rcdeterm from the Spent Fuel Pool itself, further determinations may be performied"!tio~imre accurately quantify the release for the annual effluent report.

RADIOLOGICAL IMPACT EVALUATION OF WATER LEAK AT INDIAN POINT UNIT 2

1.0 DESCRIPTION

This report documents a preliminary evaluation of the potential radiation doses to offsite receptors resulting from tha3 leakage of contaminated water from Indian Point Unit 2 (IP2) to the Hudson river. The exposure pathways considered are the ingestion of contaminated fresh-water fish and of salt-water invertebrates. It is noted that the drinking-water pathway is not included in the Indian Point Land Use Census or in the Offsite Dose Calculation Manual (ODCM). Nonetheless, for informational purposes, results are also presented for a scenario where the drinking of contaminated water is an additional exposure pathway.

2.0 INPUT VARIABLES AND ASSUMPTIONS The present analysis was based on ENTECH's AQUADOS computer code, which makes use of the models and dala in Regulatory Guide 1.109, with one exception. In the present application, and in line with the IP2 ODCM, the AQUADOS data base was modified to make use of the site-specific (Indian Point) fish bioaccumulation factor for Cs; this is equal to [224 (pCi/kg) per pCi/liter of water)], about an order of magnitude lower than the regulatory value of 2000.

The basic assumptions and input variables employed in the analysis were as follows:

(a),_ The source of the water contamination identified in the on-site monitoring wells was

-i " a'9s med to be the spent fuel pool (SFP).

iL (b)

The radionuclide concentration in the leaking water to the river was assumed to be the same as the worst-case measured value in the water collected from the cracks in the SFP concrete wall, as shown in Table 1 below.

(c)

The contaminated-water leakage rate to the river was assumed to be 10 liters/day.

(d)

The exposure interval of the offsite receptor was assumed to be 91 days (1 quarter).

(e)

The entire activity in the leaking water during the quarter was assumed to enter the river without any in-transit decay. As such, the activity released into the river during one q uarter is as follows:

Table 1 - Radionuclide Concentrations in Leak Water and Potential Activity Released to the River Radionuclide SFP Concentration Activity Released to River (PCi/ml)

2.20E-02 (pCi/ml) x 10,000 (ml/day)

91 (days) x 1.OE-06 (Ci/pCi) = 2.OOE-02 (Ci)

(e)

The activity released during the entire quarter is further assumed to get released into the river during a single 6-hour half-tidal cycle, and to mix uniformly with the average water mass that traverses the Indian Point site during the same time interval. This dilution volume is equal to 5.49E+07 m3 (1.45E+010 gal) when there is no fresh-water inflow from the estuaries (from Calculation IP3-CALC-RAD-00016, pg 45, based on the UFSAR). The scenario is equivalent to a slug of water, equal to 5.49E+07 m3, moving back and forth by Page I

the Indian Point site carrying the same concentration listed above for an entire quarter, without additional dilution. As an example, the tritium concentration in the river water, for an entire quarter, would be equal to [2.OOE-02 (Ci) / 5.49E+07 (m3)] x 0.001 (m3/liter) x 'I.OE12 (pCi/Ci) = 0.364 (pCi/liter). Refer to one of the AQUADOS computer outputs in Sec. 5 for the concentrations of the other radionuclides.

(f)

Decay correction during the 91-day exposure interval was not accounted for. Due to the long half-lives of the radionuclides of interest, decay correction in the present application is insignificantly small.

(g)

Doses were calculated by considering the following exposure pathways:

Case 1: Ingestion of contaminated fresh-water fish and salt-water invertebrate, and Case 2; Ingestion of contaminated fresh-water fish, salt-water invertebrate, and drinking water.

As noted above, the drinking-water pathway is not included in the Indian Point Land Use Census or in the ODCM. Nonetheless, Case 2 above was analyzed for informational purposes and/or use, should there be an interest or a need in assessing the potential radiological impact from the ingestion of contaminated water.

3.0 RESULTS The ACQUADOS computer outputs for the two cases analyzed are presented in Sec. 5. Refer to that section for complete details.

Summaries of the results are presented in Table 2 for the scenario without the drinking-water pathway (Case 1), and in Table 3 for the scenario with the drinking pathway included (Case 2). It is seen that the worst-case total body and critical organ doses are as follows:

Case 1 (without the drinking-water pathway):

2.50E-05 mrem/quarter, adult total body 4.15E-05 mrem/quarter, child bone.

Case 2 (with the drinking-water pathway):

3.77E-05 mrem/quarter, adult total body 6.94E-05 mrem/quarter, child bone.

For informational purposes and comparative analysis, Table 4 presents the annual doses from liquid releases from the entire site, for the calendar years 2000 to 2004. From this table, it is seen that the lbwest annual doses to the total body and critical organ are 3.4E-03 mrem and 1.06E-02 mrem, respectively, for 2004. The corresponding quarterly doses are 8.5E-04 and 2.65E-03 mrem/quarter. These are at least 30 times higher than the conservatively calculated doses (without the water-ingestion pathway) from the potential leakage of contaminated water to the river.

4.0 CONCLUSION

S Despite the overly conservative assumptions employed in the analysis, it is seen that the doses to any organ of an olfsite receptor, due to the potential leakage of contaminated water from IP2 to the river, are less than 1.0E-04 mrem/quarter, significantly lower than the ODCM quarterly limits of 1.5 mrem to the total body and 5 mrem to any organ. In.addition, these doses are at least 30 times lower than the doses from all liquid releases from the site. As such, an elaborate analysis utilizing a more refined river-dilution model is not warranled. It is also noted that the worst-case dose contributors are Sr-90 and Cs-137, which may not even get into the river because of their expected long transit time through the ground, from the site to the river.

Indeed, only tritium has been identified as a contaminant in the control wells at the site.

As a final remark, it is noted that scoping analyses based on the use of the Committed Effective Dose Equivalent (CEDE) dose conversion factors in Federal Guidance Report 11 for the ingestion pathway demonstrated that the CEDEs would be numerically very close to the whole body doses listed above. The same conclusion would also apply to the Total Effective Dose Equivalents (TEDEs) in the present applica:ion, since there is no external radiation exposure.

D. MAYER - Director Special Projects FROM:

S. SANDIKE - Sr. HP/Chem Specialist

SUBJECT:

INITIAL ASSESSMENT OF TRITIUM IN UNIT 2 STORM DRAINS Storm Drains are monitored at unit 2 as part~of the compliance commitments to Generic Letter 80-10. The sampling program includediatnnual samples of sediment and water for gamma activity as well as Tritium. Additionally, gamma counts were performed monthly on water from what was identified as key manholes (#3, 5, and 6). No gamma has been identified in Storm Drains since the Feb 2000 tube leak.

After confirmation that there was elevated Tritium in MW-I 11, Chemistry Supervisors and Staff suggested collection of additional storm drain samples in the area for Tritium. This suggestion stemmed from our operational history of potential communication between the storm drain systems and the ground water. Despite having no indication of elevated H-3 instorm drains as late as April, 2005, we felt that we should collect H-3 samples in these system prior to the next regularly scheduled annual test (summer 2006).

On Nov 10, 2005 we identified H-3 in MH-6 (approximately 80 feet from MW-1 1 location) at 51300 pCi/L, which was approximately 50 times higher than routine levels. This activity was verified on Dec 8, 2005 when another sample from MH-6 indicated 37100 pCi/L. While the downstrea m H-3 levels indicated only 2400 pCi/L or less, these levels suggested re-evaluating any potential effluent impact, should the system's final effluent point reach similar levels.

Because the discharge canal is the normal release point for all our liquid releases, dilution flow is much more easily identified than any potential release below the canal. Coupled with the REMP samples at the discharge of the canal, we felt that there would be sufficient evidence to demonstrate the effluent impact from such a release into the canal via the storm drains.

The attached calculation was therefore performed to verify that storm drain releases continue to be insignificant, and to bound a potential release into the canal, with routine dilution flow, worst case H-3 source term, and a best estimate of release flow rate from the storm drain over a quarter. Of course, this linear function can be extrapolated up or down to accommodate other flow rates into the canal, as we may later determine.

It indicates that despite the conservative inputs (including the use of 100,000 l)Ci/L Tritium source term, which is higher than anything yet identified), the observed levels of [1-3 in a release of this magnitude from the storm drain system do not result in any mathematically significant additional dose.

Since typical WB quarterly doses from liquid effluents at Unit 2 are approximately 5.OE-4 mrem or lower (<: 0.33% NRC limit), a calculated dose from this pathway of 3.6E-7 mrem is not significant and should not result in any necessary redefinition of our existing 80-10 program or trigger levels. However, these analyses provide sufficient evidence to temporarily increasYe the sampling periodicity to assist us in our attempts to map, identify, and eventually eliminate the source of Hq-3 into the local ground water. Analyses such as the bounding calculation above will be included in the annual effluent report (Reg Guide 1.21), with best measurements of all input parameters, to communicate this issue fully with the NRC.
