Request for Additional Information On Steam Generator Repair Report Revision 7
Turkey Point Unit Nos.
3 and 4
Accident Evaluation Branch Section 3.3.3, Control of Airborne Radioactivity and Surface Contamination, states that airborne radioactivity will be controlled, monitored, and released via the vent stack.
A slight negative pressure wi.ll be maintained in containment by means of the purge system, although the equipment, personnel and emergency hatches would be open.
(a)
Provide an evaluation of the capacity of the purge system, particularly its capability to maintain the negative pressure at all points in the containment.
(b)
If the hatches are open when the existing sampling station detects high airborne activity, the usual procedure of isolating input to the vent would not stop the release What emergency procedure would be used to stop release outside containment and protect workers inside containment in case of unforseen high airborne activity7 (c)
Mill the equipment hatch remain open during most of the repair
- process, or only be opened when equipment is moving in or out'?
Specifically, will the equipment hatch be open when cutting or welding operations are in progress on the primary system components?
Table 5.2-1 used to indicate activities in pCi; Revision 7 Table 5.2-1 gives activity in Ci.
Further, the extrapolation is given for 9 years of commercial operation versus 7 years, although the values in the tabl'e are identical.
If the change in the column title is presumed to be a typographical
- error, why is there no change in the values?
What is the actual extrapolation operating period?
Little detail is given of the actual operations for the replacement procedure.
When will the metal plate be welded to the bottom of the lower assembly?
Provide an evaluation of the lower assembly drop accident, including potential radiological consequences, if lifting is required before the top and bottom are welded shut.
Are there any filters in the purge system between the containment and the existing vent monitor?
A decontamination factor of 12 was assumed for purposes of evaluating radiological consequences (page 5-21b).
Although Section 3.3.5.3.2 is referenced as a description of the proposed alternatives for the decontamination process, it is not clear how decontamination can be accomplished prior to cutting the lower assembly from the channel head.
Provide a clarification of the procedure to be used and evaluate the potential for accidental radiologica'l releases due to that process.
The X/Q value used for determining the radiological consequences of
-6 airborne releases was 1.02x10 Chapter ll of the Turkey Point Unit 3 Final Safety Analysis Report uses this value for evaluating routine
- releases, since it is an average over three years.
An annual average X/Q is not appropriate for accident calculations.
Provide dose calculations for radiological assessments using -an appropriate (e.g.
2 hr., ground level) X/Q.
Enclosure 2
Request for Additional Information On the Occurrence of Endangered Species At The Turkey Point Site 1.
Provide information on the distribution, abundance, life history and
',ndicate the presence or absence of breeding areas at the Turkey Point site for the species listed on the attached table. 'articular emphasis should be placed on the American crocodile, Crocod lus acutus, the
'-erican alligator, ~Alii ator mississi
- iensis, and the Atlantic green turtle. Chelonia
~m das
~m das.
include for all species records of onsite sightings and identify any potential causal link between the steam generator repair program/demineral i er operation and the listed species.
2.
Provide a table listing all biological'onitoring studies of molluscs, vertebrates and plants conducted on or near the site that could have resulted in the co11ection or observation of an endangered or threatened species.
For each study indicate the period of time the study was conducted, the number of stations, and the freouency of
'selvation or collectison

Enclosure 3
Request for Additional Information On the Demineralizers for Florida Power and Light Company Turkey Point, Units 3 and 4
1.
Provide a general description and flow diagram of how the full flow condensate demineral izer operates.
Indicate the number of demineralizer I
vessels per unit.
2.
Indicate the anticipated, frequency of back flushing and Powdex replacement for each demineralizer vessel.
Describe how such an operation would be scheduled for the two units.
Describe how run time will be determined.
3.
Indicate the source and water quality of the backflushing liquid.
4.
Provide the volume of discharge from the demineralizer vessel to the receiving vessel.
5.
Provide the anticipated water quality values for Ph, Suspended
- Solids, DQ nd Conductivity of the supernatant discharged from the receiving vessel to the discharge canal.
6.
Indicate the anticipated type (batch or continuous),
- volume, and flow rate of the discharoe.
7.
Indicate the approximate location of the discharge point on a site map (line drawing of discharge).
S.
Indicate the amount (weight/volimie) of resin needed for replenishment of a demineralizer vessel.
~
e
~
9.
Provide an analysis evaluating the potential for adverse aquatic impacts due to increased site runoff and erosion from the laydown area and the construction of the storage building for the steam gererators.
10.
Provide an evaluation of the impact due to the increased onsite workforce on the site's sanitary waste treatment facility.
Indicate the potential for any aquatic impacts due to the increased sanitary effluents.
11.
Indicate the kind, ultimate fate, and potential for adverse aquatic impacts due to the use and dis~.isal of any chemical cleaning compounds used during and related to the steam generator repair and installation of the demineralizers and prior to station startup.
12.
Provide an evaluation of the non-radiological impacts due to the discharge of increased amounts of laundry waste water during the repair program.
Indicate the amount of laundry waste water that will be discharged daily, compare this discharge volume with the average discharge during normal operation, indicate the locati.on of discharge, describe the manner in which the waste stream is treated, indicate its anticipated water quality and postulate its impact to the biota inhabiting the canal system.
