7:00 p.m.
2 MR. NOTTOLI: Good evening. My name is Don Nottoli, Im 3
a member of the Board of Supervisors here in Sacramento County, and have 4
the distinct pleasure of not only representing the District, which Rancho Seco 5
is located but, certainly many communities surrounding that, including where 6
we are this evening, the City of Rancho Cordova, here at the Marriott 7
Courtyard.
8 So, I want to extend a big welcome to our visitors from both 9
back East but also those from the Region, and we know we have folks here for 10 the Nuclear Regulatory Commission and staff as well as obviously SMUD staff, 11 who again are the day to day responsible for the oversight of Rancho Seco and 12 a whole lot of other facilities who provide power to this community.
13 I just want to take a moment to, in addition to welcoming, you, 14 to talk a little bit about the purpose of the meeting. I had the good fortune, 15 about five years ago or thereabouts, when the NRC was out at that time in the 16 City of Galt, had a community meeting. I had a little more attendance from the 17 public but, nonetheless, we wont give up hope that some folks may arrive here 18 this evening. But, at any rate, I know the purpose at that time, and again this 19 evening, is to welcome public input, to get an overview of the reason why were 20 here, which is to talk about the licensing and the work as it relates to Rancho 21 Seco and the oversight program, and the termination of the license. And so 22 youll hear about that from folks who are much more expert than me in that but, 23 we want to encourage folks that are here from the general public, and anyone 24

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com else, obviously those of you who work very closely with this particular topic and 1
this community, and other communities, certainly to weigh in as well.
2 So, Im not going to belabor it, I could probably, you know, go on for 3
a couple more minutes this evening but I know you want to hear from the folks 4
who are expert in the field. So, I want to extend a welcome to John and to all 5
the folks that are here this evening, and on behalf of certainly the SMUD staff 6
and their Board, on behalf of the County of Sacramento and the Board of 7
Supervisors, and certainly on behalf of the general public. And again, we thank 8
you for the attention here this evening, and know that again this is part of the 9
role and the work thats very important in permitting regulatory oversight for 10 facilities that have served and do serve our communities in a variety of ways, 11 and again we want to thank folks for taking time this evening.
12 And with that, Ill turn it over to John.
13 MR. HICKMAN: Thank you. Id like to welcome you all to this NRC 14 public meeting on the Rancho Seco License Termination Plan.
15 To start with, Id like to mention that we have copies of the slides at 16 the back, as well as sign-up sheets if you want me to send you some 17 documents, the transcript of this meeting or any other NRC documents. And 18 theres another sign-up sheet if you want to make a public statement. And 19 lastly, we have an NRC feedback form, if you want to provide feedback on this 20 public meeting.
21 I guess Ill do some quick introductions here, just so you know who we 22 have. To my right we have Einar Ronningen and Steve Redeker with 23 Sacramento Municipal District, Power District. And Blair Spitzberg, who is from 24 the NRC Region 4 office. We have several other NRC staff people in the 25
5 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com audience. Claudia Craig is my Section Chief at Headquarters. Neil Haggerty 1
is one of the reviewers for the Rancho Seco Licensing Termination Plan, and 2
Jim Webb is another reviewer.
3 I guess Ill ahead and get started on presentation. To start 4
with discussing the NRC focus on decommissioning, our primary focus is on 5
the safe removal radiological hazards at the site. This process involves the 6
removal of the facility from service, the reduction of radioactive materials on the 7
site to a safe level that allows release of the site for other usage. Detailed 8
radiological surveys, which will be done by both the utility and the NRC, the 9
goal of which is to eventually lead to termination of the NRC license for the 10 facility.
11 The process that we go through as part of decommissioning, 12 initially, when the licensee decides they are going to terminate operation of the 13 facility, they submit two certifications. The first one is that they have 14 permanently ceased operation and the second one is that fuel has been 15 permanently removed from the reactor vessel.
16 Following these two certifications, we then issue a license 17 amendment that modifies the utilities license so that they can possess the 18 facility but are no longer authorized to operate it.
19 Subsequently, the licensee will submit a decommissioning 20 plan, this will describe their planned activities for decommissioning and, in the 21 case of Rancho Seco, that has changed over time. Initially they were in safe 22 store maintaining the facility and then subsequently they modified that to begin 23 active decommissioning.
24

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com They also submit, in the plan, also they have a schedule for 1
their planned activities and they have to generate a site specific cost estimate 2
for the decommissioning of the facility.
3 Subsequently, as they near the end of their decommissioning 4
activities, theyll submit the license termination plan, which is primarily what 5
were here to discuss this evening. That plan will provide a detailed document 6
that describes the condition they intend on leaving the site in and how they will 7
confirm that they decontaminated sufficiently.
8 They will then conduct final status surveys, as will we, and 9
assuming everything proceeds, they would then -- we would then terminate 10 their license.
11 During the course of decommissioning the NRC regulations 12 prohibit the licensee at any time from performing activities that would prevent 13 the site from being restricted or released for unrestricted use, that would result 14 in any environmental impact not previously considered in their environmental 15 assessment, and that would in any way result in there not being sufficient funds 16 to complete the decommissioning process.
17 The license termination plan, and this will just be a quick 18 summary of whats in there, the licensee will be providing a more extensive 19 description of whats in the LTP, provides a site characterization and this 20 includes a historical site assessment of the activities that have taken place in 21 the site over its operation. It identifies any remaining decommissioning and 22 dismantling activities they would still have to produce before theyre completed, 23 their plans for any site remediation, this would be any grading or any other 24 kinds of remediation activities they would have to do, their plans for their final 25

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com radiation surveys, description of the end use of the site and if there would be 1
any restrictions imposed, whether it would be something that lets say would 2
control the site for a certain number of years before the public would have 3
access to anything like that. They would provide an updated site specific 4
decommissioning cost at that point, updated from the decommissioning plan 5
that was originally submitted. And they provide any new information that is 6
necessary to supplement the environmental report.
7 The NRC actions, in response to receiving the license 8
termination plan, include we noticed the receipt of the plan in the Federal 9
Register and make it available for public comments. The plan is available in 10 our public document system called ADAMS, and in a copy of my slides theres 11 a reference as to how to obtain and view the document in ADAMS if you want 12 to. Opportunity for hearing is given, this is standard practice for any license 13 amendment and the license termination plan is a license amendment.
14 The NRC holds a public meeting on the license termination 15 plan, which is what were doing this evening.
16 If the plan is determined to be acceptable by the NRC, it is 17 approved by the issuance of a license amendment. In the meantime the 18 licensee will continue the decommissioning of his site, and will perform their 19 final status surveys.
20 The NRC, usually with the use of contractors, will then visit 21 the site and perform confirmatory surveys. And if the plan was followed and 22 the site meets the release criteria that is specified in the license termination 23 plan, the license is then terminated.

5 And now Ill turn it over to Steve Redeker to continue.
6 MR. REDEKER: Im Steve Redeker, the decommissioning 7
manager of Rancho Seco and Im pleased to have some other SMUD staff with 8
us here today, Einar Ronnigen, who will give the majority of the presentation, 9
and we also have some industry experts who are working with us today out at 10 the plant, preparing the license termination plan and helping us with overall 11 decommissioning. In the back, Bob Decker, John Newey, George Pillsbury and 12 Leon Brown. So, if anyone has specific questions, they can certainly help us 13 out. Thank you very much, gentlemen, for coming.
14 What are we doing at Rancho Seco? Why are we, the staff 15 at Rancho Seco there? Our whole objective is to decommission the facility in 16 such a manner that we do not harm the environment or cause any issues 17 relative to public health and safety. And we do this in a cost effective and least 18 risky manner. We want to preserve the options to reuse the site by SMUD.
19 Thats our basic purpose of our decommissioning program at the Ranch.
20 What are our goals? I tried to make this simple. What do we 21 want tod, and by when? We want to be finished with our overall 22 decommissioning plan by the end of 2008. Well clean up the site to the NRC 23 standards. We do expect to have a small volume of radioactive waste that we 24 currently dont have an acceptable place to dispose of permanently, that will be 25
9 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com stored in a radioactive waste storage building out at the site. So, by the end of 1
2008, the majority of the site will be available for reuse by SMUD with no 2
restrictions.
3 After 2008, for probably two or three years, we intend to do 4
some non-radiological, I call it industrial decommissioning, where we will 5
remove some non-radioactive portions of the plant from the site and put the site 6
in a very safe and stable condition.
7 We will continue to store the nuclear fuel, our fuel is in dry 8
storage, there s a brochure in the back that describes our dry storage system 9
and program, and it will remain in dry storage until the U.S. Department of 10 Energy comes to take it away. So, we will have a Nuclear Regulatory 11 Commission license to store the radioactive waste, that small portion, and the 12 nuclear fuel for many years to come.
13 Safety is the primary focus of our whole decommissioning 14 effort, both industrial safety and radiological safety. We, again, making it 15 simple, dont hurt anyone, dont drop anything and dont spill anything. Its very 16 easy for the workers to understand that concept. Dont hurt anyone, we want 17 to minimize any radiation exposure dose to the workers or to the members of 18 the public. We dont want any industrial accidents. Were lifting very heavy 19 things, we dont want to drop anything. And dont spill anything that relates to 20 hazardous materials, not just radioactive materials but asbestos, lead paint, 21 PCBs, many other hazardous materials.
22 So, our objective is to adequately control all of that material.
23 So, safety is primary in the whole focus of decommissioning.
24 Now, Einar Ronningen.

10 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com MR. RONNINGEN: Thanks Steve.
1 Im going to describe here, in a little bit of details, what John 2
introduced and Steve led us into here, and well start with just what is the 3
license termination plan.
4 Really what it is is a very technical document that describes 5
the Nuclear Regulatory Commission, how were going to conduct 6
decommissioning at Rancho Seco, and how were going to leave the site in a 7
manner thats acceptable to the Nuclear Regulatory Commission, that is how 8
it meets the criteria for license termination.
9 John touched on the way the NRC performs the review. We 10 did do some reviews onsite. The content of the LTP itself is specified by 11 regulations and guidance documents that are put out by the NRC. Its prepared 12 onsite with technical experts and also some technical experts from off-site, to 13 supplement the knowledge that we have onsite where its needed. For 14 example, Tom Cudzillo is here, he gave us input into our hydrogeological plan 15 that helps us to characterize the site.
16 Once its been prepared by those technical experts, its 17 reviewed again in a cross review by those technical experts, and then again by 18 Rancho Seco management. After weve reviewed it thoroughly and are happy 19 with the document, then we submit it to the NRC for their review.
20 So, what are those site cleanup criteria? Well, we want to 21 make the site available for unrestricted reuse. John had touched on the fact 22 that we could leave the site for restricted reuse but, we want to leave it for 23 unrestricted reuse. So, the laws tell us that we have to demonstrate to the 24 Nuclear Regulatory Commission that we leave the facility in such a way that the 25
11 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com dose to the worker on the site is less than 25 millirem per year. And not only 1
that, we have to introduce this concept here, that Ill touch on a little bit latter, 2
that we call ALARA, which means As Low As Reasonably Achievable.
3 We actually do a cost benefit analysis to determine how far 4
below that 25 millirem per year it makes sense economically to reduce that 5
dose.
6 Lets talk about 25 millirem here for a moment. What is a 7
millirem? A millirem is a common measurement unit that we use to describe 8
the impact of radiation on the human body. And once we have this unit 9
established, then we can talk about the relative numbers here. And on the 10 chart, you can see we go from a low of five up to 420. Just for comparison 11 purposes, weve got the 25 on the lower right there, which is the annual dose 12 that a worker at Rancho Seco could receive after license termination, and thats 13 a maximum. The lowest number there is five.
14 Someone on a cross country flight for about six hours at 15 35,000 feet might receive about five millirem. Someone getting a chest x-ray 16 might receive about 35 millirem. And to go to annual doses from natural 17 background radioactivity, you can see theres some variability. The annual 18 average for the member citizen of the United States is 360 millirem, someone 19 in San Francisco, a little bit less, about 350, someone up in Truckee a little bit 20 more elevation, a little bit more rocky soils, about 420.
21 Back in 1975 we did an aerial survey of the direct radiation 22 field and the areas around Rancho Seco, and this is not really the total 23 radiation dose someone would receive, well talk about that a little bit more later 24 but, this demonstrates the variability in the natural background radiation that 25
12 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com one receives directly from the naturally occurring radioactive materials in those 1
areas. And we can see -- Ill get the pointer out here -- weve got numbers as 2
low as about 43 down here by Comanche Reservoir, and then numbers as high 3
as greater than 160 east of Ione near Buena Vista. Now, these numbers arent 4
meant to alarm, and they arent unusual as far as the variability goes. Were 5
simply illustrating that natural background radioactivity varies so much that 25 6
millirem per year is a small number in comparison to that. And thats all this is 7
meant to illustrate.
8 We had a list before that John kind of showed us, of the 9
contents of the license termination plan, and to kind of go through here chapter 10 by chapter and give a little bit of information on each chapter, and Ill do that 11 with the highlighted chapter.
12 Chapter One is General Information about the site, some 13 history of the site, how the site operated, some geography, climate, those sorts 14 of things, and includes the location of the facility.
15 For those people that arent aware, we can see this Lego 16 shaped property that is the Rancho Seco property thats located in Southeast 17 Sacramento County, about 25 miles Southeast of Sacramento.
18 Here is a pretty good picture of the Lego shaped property in 19 the white outline here, and all the different things that are on the facility there.
20 Its almost 2500 acre facility. You can see in the upper left here, is the actual 21 industrial facility that is the Rancho Seco Nuclear Generating Station. That 22 occupies about 90 acres of the 2480 acres.
23 In green down here is the location of the new Consumnes 24 Power Plant, which is a natural gas fired power plant that SMUD is currently 25
13 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com using to generate electricity. And then over southeast of the plant here, weve 1
got some older facilities and a newer facility here that actually generates 2
electricity using the photovoltaic technique.
3 Over on the eastern part of the site here, weve got areas that 4
were never impacted by the operation of Rancho Seco. SMUD operates a 5
recreational facility around this lake here. Weve actually given some land, we 6
lease it at very low cost, to something called the Performing Animal Welfare 7
Society, thats based in Galt, that rescues circus animals and other animals 8
from around the country and provides a good life for them.
9 This red line here is the Howard Ranch trial. Immediately 10 east of the site is a property called the Howard Ranch, which is a working 11 ranch, and this is a nature trail that allows people to go and enjoy some of the 12 natural sites at the facility.
13 Recently weve turned over about 1200 of that 2500 acres to 14 the Sacramento Valley Conservancy, and what theyre going to do at the 15 facility, basically these highlighted areas, the areas down here that are the 16 Performing Animal Welfare Society as well.
17 It looks like weve got someone trying to join us via wireless 18 network here, join us on the meeting.
19 What the Sacramento Valley Conservancy is going to do is, 20 theyre taking over custodianship of the land and stewardship of the land, as 21 part of SMUDs commitment to the environment and protecting the 22 environment, theyre going to monitor the cattle grazing that occurs in the area, 23 also set aside areas for preservation of endangered species.
24

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com In Chapter Two, we move into Site History and Characterization, 1
where radioactive materials were used and stored onsite, and unfortunately, in 2
some instances spilled. And then we did a characterization of the site where 3
we actually went out and numerically determined how much radioactive 4
material was in each location. That helps us plan the work that we need to do, 5
and lets us know where we need to actually do remediation to reduce those 6
levels below that 25 millirem per year.
7 Chapter Three talks about the decommissioning activities that 8
are remaining at the facility. We had presented those to the NRC in our 9
decommissioning plan before, but, these are those activities that are left, that 10 need to be completed, to terminate the license. And Ive got a couple of 11 pictures here.
12 This is sort of a before picture, Ill flash it up, an after picture.
13 You can see a lot of things go away. The point here is weve got outside tanks, 14 temporary metal buildings in different areas. Weve got this temporary Quonset 15 hut up here, these building out by what were spray ponds. And you can see in 16 the after picture that all that structure is gone.
17 Basically what you see here are all the permanent concrete 18 structures at the facility, and thats basically what the facility is going to look like 19 upon completion of license termination.
20 Heres a picture of some demolition occurring of one of those 21 temporary buildings. What I wanted to point out here is that we generate a lot 22 of materials during the decommissioning process, but we do monitor all of this 23 material for radioactivity. Any material that contains measurable radioactivity 24 is disposed of at a waste disposal facility. Only when material can be 25
15 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com demonstrated to have no measurable radioactivity, is it allowed to go to a 1
landfill.
2 Chapter Four is the chapter where we talk about site 3
remediation. Heres where the rubber meets the road, as far as that ALARA 4
concept that we talked about before. Within Chapter Four is where we actually 5
do the calculations that determine the cost, not only to SMUD for the 6
performance of this extra work but, also to society. If were going to remove 7
ten truckloads of dirt to meet the 25 millirem per year, and we decide we want 8
to go say 20 millirem per year, and remove two more truckloads of dirt, well, 9
now weve got more trucks on the road and theres a possibility of an accident.
10 That has a societal cost, even though the risks are low. But, thats where we 11 perform those calculations.
12 Also in Chapter Four, we describe how were going to 13 remediate the facility, and that is remove that residual radioactivity and get it 14 down to a level that is below 25 millirem per year. And of course weve got a 15 couple of pictures here.
16 Heres one of a machine that actually shaves off the surface 17 of concrete in a very uniform manner, quarter inch or half inch, after its been 18 run over the surface you can see it leaves a rather smooth surface behind.
19 When theres residual radioactivity right in that upper layer, sometimes we have 20 to get a little bit more aggressive and use jack hammers, or we even have 21 some really big equipment that we use in the facility to really knockout concrete 22 when we have to really get aggressive.
23 When were not so aggressive, you can see a rather smooth 24 surface thats left behind, and a nice equipment pad here where some 25

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com equipment had been used before but, where we need to, we go in and really 1
get aggressive on this concrete and take out three or four inches off the floor.
2 You can see the exposed rebar down there. So, whatever we need to do to 3
reduce the levels of residual radioactivity to meet that license termination 4
criteria.
5 We move on to Chapter Five, after weve remediated the site, 6
now weve got to take measurements to demonstrate to the NRC that we do in 7
fact meet the license termination criteria, and thats what Chapter Five does.
8 Its the final status survey plan.
9 This is where we tell the NRC how were going to ensure 10 them that we are in fact below 25 millirem per year. It describes how were 11 going to take the measurements, where were going to take soil samples, 12 where were going to monitor surfaces, outlines the quality program, well talk 13 about in a moment. And also provides the content of the final report. When we 14 submit this final status survey report to the NRC, thats the last time that were 15 going to monitor a particular area for the radioactivity in that area, and we want 16 to make sure we provide them with the information that they need to be 17 confident that they are aware of how were leaving the site.
18 How do we measure whats left? Well, we prepare very 19 detailed instructions and we literally take thousands of measurements in 20 building, soil, water, and we take field samples out there that are brought back 21 to the laboratory for analysis. And then we take all this data and compare it to 22 acceptance criteria. Well talk about that in the next chapter a little bit. If the 23 numbers come out too high, we perform additional remediation as needed.
24

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com And then we prepare that detailed report of results that get submitted to the 1
NRC.
2 For quality purposes, not only do we look over our own 3
shoulder but, as John mentioned before, the NRC is going to look over our 4
shoulder as well. Sometimes well go into a particular portion of a facility and 5
well do the final status survey, and then well send a different technician in and 6
well do it again to make sure the results compare and that were doing 7
everything the way that were supposed to.
8 We also have internal quality assurance people onsite that 9
will look over our shoulders and make suer that were performing everything 10 according to the way that we told the NRC that we would.
11 And then as John mentioned, the NRC comes in, and Blair 12 is going to talk about that a little bit. We have inspectors that come in and 13 monitor what were doing, and then there are contractors, mostly the Oakridge 14 Institute for Science and Education, come in and actually take samples and 15 perform verification measurements.
16 There is a picture of technician doing some monitoring on a 17 wall, at the point here hes using a very sensitive detector, and you can see the 18 cabling here that connects it to the little hand held computer. This guy is 19 monitoring a floor here. The person helping him is the second technician thats 20 got this hand held computer here that records all the information, as we do the 21 monitoring.
22 So, you can see shes got some paperwork here, hand 23 records are taken, computer records are taken, were very thorough on how we 24 record this data, so we can present it in the proper way to the NRC.
25
18 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com Heres the drilling rig that we had onsite to perform drilling to 1
establish some monitoring wells onsite, so we could monitor the ground water 2
at Rancho Seco. The results of that ground water monitoring showed that 3
there was no radioactivity of plant origin in the ground water at Rancho Seco.
4 But, the only way we could know that is to drill the wells and perform that 5
monitoring.
6 Here weve got a bunch of different activities going on.
7 Weve got some buried piping here thats going to be removed, that contains 8
some radioactive contamination. Then over here weve got a technician thats 9
surveying the soil and making sure that the soil is acceptable in the areas 10 where were working. And again, weve got the second technician thats 11 monitoring the first technician and recording data as he goes along.
12 That takes us to Chapter Six, which talks about Dose 13 Modeling. Heres where we demonstrate to the NRC and establish what the 14 release criteria are going to be. We have these things called derived 15 concentration guideline levels that are the acceptance criteria, and what I mean 16 by that is that when we take an instrument out into the field, it cannot measure 17 25 millirem per year, theres no instruments that do that. Number one, its a 18 very low dose rate, difficult to measure and, number two, as well see in a 19 minute, radioactivity impacts the body in a couple different ways, not just 20 directly, thats something we can measure with an instrument.
21 So, we developed these DCGLs, which are the numbers that 22 tell us how were going to meet that 25 millirem per year. In this case, were 23 going to leave the facilities behind, SMUD is going to reuse the facility. Weve 24
19 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com got industrial workers that are going to be occupying the facility, so thats what 1
we based our dose modeling on.
2 The next picture that were going to go to is going to describe 3
some of the ways that radioactivity can interact with the human body. Its 4
something that happens with naturally occurring radioactivity, and thats sort of 5
a point that I want to make, is that we saw some numbers in the variability 6
around Rancho Seco that varied from 43 up to 160 something.
7 Previous slides before that, I said the average member of the 8
public receives about 360 millirem per year. So, whats the difference there?
9 Well, naturally occurring radioactive material exists in the soil around your 10 home, it exists in the water that you drink, so theres different ways for that 11 radioactivity to impact the body. You drink the water that contains that 12 radioactive material, youre going to get some radiation dose from that. Were 13 all adults here, we dont eat mud pies anymore but, there is a chance to 14 actually ingest some soil that might contain naturally occurring radioactive 15 material.
16 So, theres a bunch of different ways and we have to take all 17 of these different ways into consideration when were talking about the residual 18 radioactivity left behind at Rancho Seco.
19 Argonne National Laboratory, as it states up here, is actually 20 the facility that developed the computer code that we use to take that 25 21 millirem per year and making it something meaningful that we can measure.
22 And in the case of an industrial worker, we have all these different potential 23 exposure pathways. We can have radioactive material in the soil or on the 24 surfaces of the building, that would directly impact the body, sort of like an x-25
20 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com ray. Like I had mentioned before, weve got naturally occurring radioactive 1
material in ground water that people drink, or we could have residual 2
radioactivity in the soils of Rancho Seco that could eventually leach into the 3
ground water and then get into the drinking water and impact the body that 4
way.
5 I need to make the point here that the dose calculations that 6
we do are actually for a duration of 1000 years after the license termination.
7 And the reason that we do that is, it would be possible perhaps for some 8
material to get into the soil and then take many, many years to impact the 9
ground water. And then through the drinking water, impact the people at the 10 facility. Everything that weve done, and all the studies that weve done, show 11 that we dont have that pathway at Rancho Seco, but the means exist in the 12 computer code to make that calculation if we had to.
13 So, this picture is really for illustrative purposes only. Weve 14 got this dust and Radon cloud here, and there really isnt brown dust of 15 radioactivity surrounding Rancho Seco. Its really just a cartoon to illustrate the 16 different pathways.
17 We get into Chapter Seven, Financial Information. John had 18 mentioned that there some restrictions on money that we can spend. We want 19 to make sure that we dont put ourselves in the financial position that we cant 20 complete decommissioning. So, in Chapter Seven, we give an estimate of the 21 cost to complete all the work thats remaining for the license termination 22 process, and then show how were going to pay for that work and assure the 23 NRC that we will have the money to pay for it.
24
21 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com Chapter Eight, Environmental Impacts, weve done 1
environmental reports for building Rancho Seco, operating Rancho Seco, 2
decommissioning Rancho Seco. We want to take a look again and see if the 3
license termination is going to change any of the environmental impact studies 4
that weve done in the past. We evaluate impacts to threatening endangered 5
species, water quality in the area. There could be archeological resources of 6
people, remember when we put in the gas pipeline for the Consumnes Power 7
Plant, we found some Wooly Mammoth bones and SMUD was very careful in 8
taking care of that. And then this thing we call Environmental Justice, to make 9
sure that if we are impacting the environment, if there is going to be impacting, 10 that were doing it in a fair manner.
11 Steve kind of covered the schedule, Ill just give a wrap-up 12 summary here. We expect to have all the radiological work done and license 13 termination surveys complete by 2008. At that point were going to reduce the 14 NRC license to about a one acre facility and have some legacy waste stored 15 on site for a number of years. After that waste is shipped, well perform the 16 same monitoring on that one building that were leaving the waste in, as we did 17 for the rest of the site. And then finally completely terminate the license.
18 And as Steve mentioned, we are going to do a little bit of non-19 radiological work for a couple of years, after the radiological work is complete 20 at the facility.
21 If you want some more information, John mentioned in his 22 that hes got some access to the ADAMS website, its spelled out on the slide 23 here what that stands for. And they also have a lot of information on 24 decommissioning in general, and weve got that website available on our slides.

(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com And some contact information, Steve Redeker and myself, 1
Bob Jones, who is not with us tonight, is our licensing engineer, and Dace 2
Udris is here form our Public Information.
3 And with that, I believe Ill turn it over to Blair. Ill get your 4
presentation setup here. All yours.
5 MR. SPITZBERG: Okay. Good evening. My name is Blair 6
Spitzberg. Im here representing the Region IV Office, which is located in 7
Arlington, Texas. I work as the Chief of the Fuel Cycle and Decommissioning 8
Branch in the Regional Office, and our responsibility is to perform safety 9
inspections of decommissioning activities at nuclear facilities within our reach, 10 and also have responsibility for inspecting spent fuel storage facilities in our 11 region.
12 Over the next few minutes, I hope to explain a little bit about 13 our inspection program and how we conduct it at the Rancho Seco facility.
14 Just to let you know where we come from, this map actually 15 shows only three of the regions, because the materials program for the eastern 16 half of the U.S. has been combined into Region 1. We actually have a Region 17 2 office in Atlanta, Georgia for the power reactor program.
18 Region IV is the western half of the United States, as you can 19 see it looks very much like the Louisiana Purchase. The states in blue are 20 what we call agreement states, in which the states have certain regulatory 21 responsibilities over radioactive materials. However, they have very little 22 responsibility over nuclear power plants. The brown states are the non-23 agreement states.
24
23 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com Our office is in Arlington, Texas, which is right between Dallas 1
and Ft. Worth, and were about 15 or 20 minutes from the DFW Airport.
2 The Regional Office has about 160 employees, and my 3
branch is within the Division of Nuclear Material Safety, which is one of three 4
technical divisions within our office. My branch includes seven inspectors, 5
several of whom are qualified decommissioning inspectors, and have been 6
involved in the inspection of the Rancho Seco facility.
7 The Regional Office only has two major responsibilities. The 8
first is the implementation of the NRCs inspection program. Thats our major 9
reason for existence.
10 Our second responsibility is that of emergency response. We 11 would be the first agency responders to any event or emergency at NRC 12 licensed facilities. While this response mode has seldom been used for actual 13 events, we train and drill hard in the event that one were to occur.
14 Both the regions major areas of responsibilities, the 15 inspection and emergency response are better performed by the Regional 16 Office, because were isolated from the headquarters office, which deals more 17 with policy and program management, and a lot of the other activities that are 18 not associated directly with direct oversight of the licensees.
19 This is just another map showing the decommissioning sites 20 in Region 4, of which Rancho Seco is one of four power reactors. Actually, I 21 guess you could throw the Pathfinder side in South Dakota in that group also.
22 That license is also going through final decommissioning but, that was a much 23 smaller reactor facility.
24
24 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com I also have the responsibility for some major fuel cycle 1
facilities located, one is General Atomics in Southern California, and several in 2
3 I want to talk, spend just a minute talking about how NRC 4
ensures the safety. One of the fundamental features of the safety of nuclear 5
areas is what we call the Defense In Depth, and that means essentially that the 6
processes and equipment that are important to ensuring safety, that at least 7
two independent controls be in place to prevent unsafe conditionings from 8
occurring. So, I like to thin of the NRCs regulatory programs also in terms of 9
the Defense in Depth.
10 The first layer being the safety oversight that stems from the 11 regulations codes and standards that have been established and must be met 12 by the licensees.
13 The second layer is the site specific safety reviews and 14 licensing safety analysis performed by the program office in Washington D.C.
15 And the license places specific safety requirements on the licensee, which are 16 not codified in the regulations, and are specific to each licensees activities.
17 The third layer of the NRC regulatory oversight involves the 18 area of inspection and enforcement, and thats the area that my office is 19 involved in.
20 In any case, the inspection and enforcement is what the 21 Region IV office is primarily responsible for and its like the old saying that 22 Ronald Reagan used to use, Trust but verify. We trust our licensees to 23 perform in accordance with all of their safety requirements but, on occasion we 24
25 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com find that there is some problem with that process, and we like to catch it early 1
before something can become more problematic.
2 The objectives of the NRC inspection program are fairly 3
straightforward, its to verify the safe conduct of the licensees activities and to 4
verify the adequacy of the licensees controls, and to examine trends in licensee 5
safety performance.
6 The NRC inspection program for the Rancho Seco facility has 7
been implemented in some areas by inspectors out of our headquarters office 8
but, primarily, for the most part, the inspection programs have been 9
implemented by region based inspectors and those inspectors in my group.
10 In general, the inspection program for decommissioning 11 reactors consists of two categories of inspection. We have what we call the 12 core program, thats a group of safety areas that we inspect as part of the 13 routine scheduled inspections. And for reactor sites like Rancho Seco, that are 14 in a state of high decommissioning activity, we inspect the core inspection 15 areas at least semiannually.
16 We also have a set of inspection procedures that we call on 17 called discretionary inspection procedures, which are detailed reviews of 18 particular functional areas. These inspection procedures are conducted based 19 on the licensees activities at the time of the inspection, or may be based upon 20 licensee performance in areas found to be weak or declining.
21 This slide shows some of the core decommissioning 22 inspection procedures, which are routinely implemented at the Rancho Seco 23 site. Since this is a meeting about decommissioning activities, I have not 24 shown another area that my organization is responsible for, and thats the 25
26 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com spent fuel storage, the dry storage of the spent fuel at the site. I also have 1
responsibility for that area, so I put this in here as safety of spent fuel. Thats 2
not strictly a decommissioning inspection area but, its an important area that 3
we also devote resources to.
4 One of the things Id like to just mention briefly is the quality 5
of the inspection staff that we bring to bear on the inspection program. These 6
are highly qualified, dedicated and hard working inspection staff. Most of our 7
inspection staff have advanced degrees in physical sciences, and most also 8
have many years of experience in the field of health physics and nuclear safety.
9 In addition to their academic training and experience prior to joining the NRC, 10 we also have a rigorous internal training and qualification process that they 11 must complete before theyre allowed to conduct inspections in any given area.
12 The NRC inspection staff is very dedicated to safety at the facilities they inspect 13 and are driven to find problems which could affect safety.
14 Now, Id like to also take this opportunity to introduce Mr.
15 Emilio Garcia, who is one of our senior inspectors from the Regional Office, 16 and hes one of the principal inspectors at the Rancho Seco site. And Id like 17 to offer you all the opportunity to introduce yourself to Mr. Garcia during the 18 meeting and ask him any questions you might have.
19 The findings of the inspection are typically debriefed to 20 management. Actually, before the management debrief, quite often I get calls 21 from the inspectors from the field, prior to their exit meeting at the end of the 22 week, to let me know what their preliminary findings are. Once they get back 23 to the office, we setup a management debrief, usually the week following the 24 inspection, and thats where they debrief their findings to not just me but the 25
27 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com other regional managers. And we make a determination of the significance of 1
the findings of the inspections.
2 If there are significant findings from the inspection, violations 3
rising that have certain safety significance associated with them, it may be 4
important for us to take enforcement action with the licensee.
5 In other cases, where theres no significant inspection 6
findings, we still issue an inspection report detailing what we looked at and 7
what state of safety and compliance the plant was in.
8 Our inspection reports are available to the public for the most 9
part, there are some exceptions to that, and these are the ones that I think you 10 would probably take some comfort in, that we dont issue inspection reports 11 dealing with -- that have a lot of information on physical security or safeguards 12 information, or information that could place the plant in jeopardy if it fell into the 13 wrong hands but, for the most part the decommissioning inspections are 14 publicly available on our website at NRC.gov. And here you just go to the 15 reference library and click on the ADAMS and then NRC Public Electronic 16 Reading Room.
17 One of the other things we do, as part of our inspection 18 program, is we track and followup on safety issues. So, if we have a problem 19 thats identified during one inspection, we assign a tracking number to it and we 20 keep tracking that item until the licensee has taken effective corrective action.
21 Id like to just close with just summarizing what our 22 inspections have revealed during the decommissioning process at Rancho 23 Seco. Rancho Seco has a good inspection history with the NRC during the 24 decommissioning phase. The inspection findings and violations have been of 25
28 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701www.nealrgross.com low safety significance and theyve been rare, and overall we would say that 1
Rancho Seco has an excellent safety record.
2 So, with that, Id like to close and I think were going to open 3
it to questions.
4 MR. HICKMAN: Does anybody have any questions on 5
anything theyve heard this evening?
6 (No response.)
7 MR. HICKMAN: And I dont believe we had anybody sign up 8
for any public statements, so that will conclude this evenings meeting. Thank 9
you for coming.
