ATI7C N W P 1 hU@SC SUINEY - QUESTICNS AND ANSWERS I.

Waste Managment A.

Spent fuel questions:

1.

Question: hhich of the follcwing current, techniques for at-reactor storage are you using and hcw?

Answer:

A.

Re-racking of spent fuel - During the construction

phase, GSU changed the design of the spent fuel pool storage racks to acecmw3 ate densified fuel storage.

B.

Control rod repositioning GSU has shuffled control cell blades incore to delay cont ol rod replacement.

C.

Above ground dry storage - No.

D.

Ionger fuel burnup - Yes, GSU has implemented this action to optimize fuel and reduce discharge bundles.

E.

Other (please identify) - N/A 2.

Question:

Do you plan on continuing the use of these current techniques for at-reactor storage of spent fuel during the remaining time of your operating license or do you expect to change or modify them in sane way?

_ Answer:

GSU may consider future installation of high density l

fuel racks in the upper containment pool to accomodate full core discharge to improve refueling operations and to provide additional space which is currently reserved for fuel core offload; this may be considered in coniunction with the anticipated delavs in spent fuel pick-up by the U. S. Department of Energy frcm River Bend Station. GSU may consider upgrad.tng the fuel pool cooling capacity to accamodate decay heat rmoval required for fuel pool capacity.

3.

Question: hhich of the following techniques for at-reactor storage do you anticioate using until off-site spent fuel storage becanes available and how?

Page 1 of 7

(

Answer:

A.

Re-racking of spent fuel - See question 2.

h B-Control rod repositioning - See question IB.

C.

Above ground dry stcrage - Ib.

D.

Ionger fuel burnup - Yes.

E.

OLier (please identify) - N/A, 4.

Question: Will the techniques described above be adcquate for continued at-reactor storage of spent fuel for the c5erating lifetiane of the plant, including a 20-year period of license renewal, or are you developing other p1ar. '

Are er:

These techniques trill not be adequate without the DOE

~~

services as outlirvi in the Ir>E " Spent Puel Disposal" contract.

GSU expects that the DOE will ecuply with its contractual ecrmitznents as specified.

5.

Question: Do you anticipate the need to acquire additienal land for the storage of spent-fuel for the operating lifetime of the plan' including o 20-year period of license renewal?

1 se, hcw much land? When sculd this acquisition occur? hhere?

(If answer is "yes",

3-4 sentences)

Answer:

GSU does not anticipate acquiring additional land based on the DOE cenplying with its contractual ecnmitments.

6.

O.testion: Do you anticipate any _ additional construction activity on-site, or inmediately adjacent to the pcur plant site, associated with the continued at-reac+or storage of spent fuel for the operating lifetime of the plant, including a 20-year pericd of license renewal?

t Answer:

No.

7.

Question:

If you answred yes to question 6,

briefly describe this construction activity (e.g.,

expansion of fuel storage pool, building above grcund dry storage facilities).

Answer N/A B.

Im-level radioactive wacte managanent quest u ns:

Page 2 of 7

1.

Question: Under the current scheme for LU51 disposal (i.e. LIJ51 Tolicy Amendments Act of 1985 and regional conpacts) is there currently or will sufficient capcity for wastes generated during the license renewal peried be available to your plant (s)? If so, what is the basis for this conclusion?

Answer:

Yes.

Subject to the provisions of the low-Imel Padioactive Waste Policy Amendments Act of 1985 and during the three (3) Year licensing period beginning January 1,

1990 and c! ding Deember 31, 1992, each ectrercial nuclear reactor has an allocation of Icw-level radioactive waste disposal capacity available to them.

Based on the "Methcd of Calculation" found in a

the LUM Poliev Amendments Act of 1985, River Bend Station has an aggregate dis psal capacity of 55,188 cubic feet.

River Bend Station has implanented an administrative policy limiting the-yearly disposal volume to 12,000 cubic feet for the three (3) year licensing pericd. This allcus a buffor of 19,180 cubic feet in the event River Bend encounters an unschtduled maintenance outage or nere waste is generated during the seneduled outages than is expected.

For thc period beginning January 1,1993 and endina Auaust 29,

2025, River Bend will be cubjecu to the provisions outlined by the Central hterstate Io.r-Level Radioactive Waste Campact Ccmnission for disposal of radioactive waste in the disposal facility within the Central State Ccanpact regicn.

2.

Question:

If for any reason your plant (s) is/are denied access to a licensed disposal site for a short period of time, what plans do you nave for continued LIRf disposal?

Answer Presently River Bend Station uses the Chem-Nuclear l

Systans, Inc. Barnw il Waste Managm.ent Facility t

located in Barnw11, South Carolina for disposal.

In tr.e event this privilege is lost, River Bend has a Sito Use Permit for the US Ecolcgy disposal facility located in Richland, Washington.

l 3.

Question:

In a couple of pages, please describe the specific methcds of LUM managcrnent currently utilized by your l

plant.

l Answ r The motheds of LIR4 managment are governed by Piver Bend station procedures. These procedures outline the methods of handling, control and storage of radioactive waste.

For canpactable and non-ccmpactable Di'f Active Waste (DAW), color ceded containers are used for their Page 3 of 7

collection (i.e. yellcw containers with yellcw bags are identified for contaminated waste; green containers with red bags are identified for ptentially contaminated waste).

The DN1 is normally picked up on daily basis and brought to the radvaste building for a

segregation and sorting into radioactive

waste, non-radioactive waste, hazardous waste and mixed waste.

'Ihe ccrrpactable radioactive waste is then pre-ecrnpacted into drtrns using a nuclear packaging waste campactor and stored on site, once a sufficient quantity of pre-ectnpacted drums is produced, the load is ship:ed offsite to a super ccrnpaction facility for furtier volum redttetion prior to disposal.

The non-ecmpcetable radioactive waste is packaged in boxes.

Once a sufficient quantity of boxes is produced, the load is shippec' offsite to a decontamination facility for further volume reduction price to disposal.

The liquid radioactive waste, i.e. sludges, resins etc., is processed using River Bend Station procedures.

These procedures provide reasonable assurances and documntation that the liquid radioactive waste is processed and packaged in accordance with the specifications set forth by th' disposal site, state and federal regulations.

Question: What percentage of your current LLMV (by voltriie) is managed by:

Answer:

A.

Waste ecmpaction?

26.00%

B.

Waste.tegregatic,n (through special controls or segregation at radiaclon check point)?

1.00%

c.

Decontamination of wastes?

1.00%

D.

Sorting of waste prior to shipmnt? _ Included in A E.

Other - Solidification / Dewatering?

72.00%

4.

Question:

In a couple of pages, please described the anticipated p hns for ILM4 managcment to be utilized by your plant (s) during the remainder of the operating license and through the license renewal term.

Answer:

The basic nothods of ILM1 management for the anticipated future will be the same as discussed in question #3 above with the folicwing exceptions:

Page 4 of 7 m___.m.

1.

River Bond Station will establish a contract for offsite vendor support for large scale decontamina-tion of non-ecrnpactable radioactive waste.

2.

River Bend Station is evaluating the possibility of changing frcrn solidification to 100% dewatering of liquid radioactive waste.

Questient khat percentage of your _ anticipated waste (by volume) will be managed by:

Answer:

A.

Waste (super) canpaction?

25.00%

B.

Waste segregation (through s1.ccial controls or segregation at radiation check points)?

1.00%

C.

Decontamination of wastes?

Question: If you answered yes to question 7, briefly descriha diis construction activity (e.g.,

storage areas for steam generator components or other materials exposed to reactor environment).

Answer:

In the event the Central State Ccmpact disposal site is not in operation by December 31, 1992, River Bend Station m:y be forced to store radioactive waste on site until this facility is available.

3.

Question: To provide information on future low-level waste streams which may effect workforce icvels,

exposure, and waste ccupact planning, do you anticipate any major plant tradifications or refurbishment that are likely to generate unusual volumes of low-level radioactive waste prior to, or during, the relicensing pericd for the plant? If so, please describe these activities. Also, what types of rrodifications do you anticipate to be necessary to achieve license renewal operation through a 20-year license renewal term?

Answer N/A C.
