The staff has determined it will need the additionalinformation identified in the enclosure in order to complete its review. In order for the staff to support your requested review completion schedule, please provide the requested information within 30 days of receipt of this letter. The information in the enclosure and this request and the scheduled l response date have been previously discussed and agreeo spon with Mr. P. Wells of GPU l
Nuclear, Inc., and a copy of this letter is being faxed to Mr. Wells.
l If you have any questions, please contact me at (301) 415-1402.

Technical Specification Chanae Reauest (TSCR) 272 Reactor Coolant System Activity
Reference:
GPU Nuclear letter to the NRC dated October 19,1998 (1920-98-20210) titled, ,
" Technical Specification Change Request (TSCR) No. 272." i
- 1. In the " Flashing and Evaporation to Dryness Calculation" in Enclosure 4 (page 6 of 20) to the above referenced letter, you used an equation derived in NUREG/CR-5950 (equation 15 on page 13) to determine the primary coolant lodine partition coefficient. !
l This equation was developed for use in determining an iodine partition coefficient in a !
quiescent water pool and is not applicable for the once through steam generator l (OTSG) primary coolant flashing into the secondary side. The primary coolant which leaks into the shell side of the OTSG will flash to. steam and iodine in the leaked primary coolant will be immediately vaporized and become airborne due to the flashing and atomization.
The staff sssumes an iodine partition coefficient of 1 (no iodine partition) for the primary coolant leaked to the OTSG since the secondary side of the OTSG will contain no water during the MSLB accident. The staff requests that you recalculate the radiological consequence with no iodine partitioning.
- 2. In the " Flashing and Evaporation to Dryness Calculation" in Enclosure 4 (page 10 of
- 20) to the above referenced letter, you used iodine volatility values provided in a table contained in NUREG/CR-5732 (Table 3.8 in page 28) to determine primary coolant iodine decontamination by evaporation to dryness on the OTSG tube surfaces.
These figures are only applicable to iodine evaporation in a quiescent state and only up to 95'C (this reference used evaporation of iodine solution in a beaker to dryness i on an hot plate). These figures are not applicable for the OTSG primary coolant !
flashing into the secondary side. The staff believes that atomized primary coolant will i not be able to settle on the OTSG tubes to be evaporated. Instead it will vaporize '
instantaneously and become airborne. The staff requests that you recalculate the radiological consequence with no iodine decontamination due to evaporation to ;
dryness on the OTSG tubes. l l
- 3. In the " Flashing and Evaporation to Dryness Calculation"in Enclosure 4 (page 15 of l
- 20) to the above referenced letter, you used NUREG/CR-2713 to determine vapor deposition velocity of iodine on the OTSG tube surfaces.

l The iodine deposition velocity measurement provided in the NUREG has limited
{ application since it was performed on a simple and limited scope as stated in the i
NUREG. The staff believes this experiment is not applicable for estimating iodine deposition velocities on the surfaces of the OTSG tubes. In addition, you have indicated that this iodine deposition velocity becomes only important late in the l cooldown period when the tube surface temperaturo drops below on or about 300* F l
(about 11.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> after the accident). Justify the applicability of the iodine 1
deposition velocity measurement provided in NUREG\CR-2713 for estimating iodine deposition velocities on the surfaces of the OTSG tubes.
The above questions are necessary in order for the NRC to evaluate radiological consequences from a main steam line break accident to ensure that the resulting 2-hour doses at the exclusion area boundary and the 30-day dose at the low population zone will be a small fraction of the 10 CFR Part 100 dose limit and that control room operator dose will be within the criterion specified in General Design Criterion (GDC) 19 of 10 CFR Part 50.
