Okay, welcome to everybody.
4 My name is Joel Weibe.
I am the NRC Petition Manager 5
for Petition Sam, submitted on November 15th.
6 We are here today to allow the Petitioner, 7
Sam Miranda, to address the Petition Review Board 8
regarding the PRB's initial decision to recommend not 9
accepting the 2.206 Petition dated November 15, 2016.
10 The Petition Review Board's decision is based on 11 Management Directive 8.11, Part 3, Charlie Two Bravo.
12 The criteria for rejecting petitions under 13 10 CFR Part 2.206, and specifically, the Petitioner 14 raises issues that have already been the subject of 15 NRC staff review, and the issues have been resolved 16 for the Braidwood and Byron facilities.
The PRB 1 7 determined - -
also determined that significant new 18 information was not provided.
19 As part of the Management Directive 8.11 20 process, Mr. Miranda had requested this opportunity to 21 address the PRB regarding its decision.
This meeting 22 is scheduled from 1:00 to 2:00 p.m., Eastern time.
23 The meeting is being recorded by the NRC Operations 24 Center, and will be transcribed by a court reporter.
25 The transcript will become a

Welcome to NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
7 1
this meeting regarding the 2.206 Petition submitted by 2
Mr. Miranda.
I'd like to first share some background 3
on the 2.206 process.
4 Actually, 2.206 of Title 10 to the Code of 5
Federal Regulations describes the petition process, 6
the primary mechanism for the public to request 7
enforcement action by the NRC in a public process.
8 This process permits the NRC to take enforcement-type 9
action related to NRC licensees or licensed 10 activities.
11 Depending on the results of its 12 evaluation, NRC can modify, suspend or revoke an NRC-13 issued
- license, or take any other appropriate 14 enforcement action to resolve the problem.
15 The NRC staff guidance for the disposition 16 of 2.206 Petition request is in Management 17 Directive 8.11, which is publicly available.
18 The purpose for today's meeting is to give 19 the Petitioner an opportunity to comment on the PRB's 20 recommendation not to accept the Petition.
This 21 meeting's not a hearing, nor is it an opportunity for 22 the Petitioner to question or examine the PRB on the 23 merits of the issues presented and the Pe ti ti on 24 request.
25 No decisions regarding the merits of the (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701
. (202) 234-4433
8 1
Petition will be made at this meeting. Following this 2
- meeting, the Petition Review Board will hold an 3
internal meeting to consider the need to modify its 4
recommendation.
5 The final recommendations will be included 6
in an acknowledgment letter to the Petitioner.
And 7
I'll just one thing that's not in the script.
If 8
you look at 8. 11, we' re implementing a paragraph 9
that's under the part that says, Rejecting a Petition.
10 And so sometimes we choose very harsh 11 words.
So it's not that the concerns that you have in 12 the Petition are not without merit. It's just that in 13 the
- process, some of these have already been 14 considered.
So this is more the end of a particular 15 episode, but really there's other episodes that are 16 continuing in this particular area.
17 So it's not that what you have suggested, 18 Stan, is without merit.
It's just that using the 19 criteria of the petition process, doesn't qualify as 20 a petition.
So with that I will turn it over to you 21 and allow you to comment on the PRB's recommendation.
22 We appreciate -- it's like anything else.
23 We appreciate now the public giving us their 24 technical -- that's sort of my point.
25 (202) 234-4433 MR. MIRANDA:
Okay, well, last time I was NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
9 1
- here, I
supplemented my Petition with a
long 2
statement.
Okay, missed at least one new item that 3
was not in the Petition.
4 And I don 1 t intend to go through the 5
Petition part by part.
You have the Petition.
6 COURT REPORTER:
I'm sorry to interrupt, 7
Mr. Miranda.
This is the court reporter.
I'm going 8
to have to ask you to speak up.
9 MR. MIRANDA:
I'm sorry.
10 COURT REPORTER:
Thank you.
11 MR. MIRANDA:
I was saying that the last 12 time I was here, I had read a long statement took 13 about an hour and 15 minutes I think -- which was not 14 a reading of the Petition.
It was supplemental, and 15 there was at least one item in there that was due, not 16 included in the Petition.
17 And I also provided two handouts, which 18 were in the supplemental statement I provided to Joel 19 Wiebe, which he included in the record.
So you had 20 lots to read here, and I assume that you've read it.
21 So I'm not going to go through all of that again, 22 except maybe one or two technical points, which I 23 consider important.
24 And I also consider that these points by 25 themselves are necessary and sufficient to get the (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
10 1
Petition reviewed.
There's no point in embellishing 2
that.
3 I would also point out a small observation 4
that of all the people in this room, I'm the only one 5
here not being paid to be here.
I'm retired, and I 6
should be in Florida on the golf course.
7 UNIDENTIFIED SPEAKER: Especially on a day 8
like this.
9 MR.
MIRANDA:
I will point out one 10 paragraph in the benefit directive letter (phonetic).
11 It's under the section called, Office Directives, 12 Section 33.
It says, have overall office practice, 13 have overall responsibility for assigned petitions, 14 because 10 CFR 2.206 Petitions are requesting 15 enforcement-related action.
16 Petitions are assigned to the Office of 1 7 Nuclear Reactor Regulation, the Off ice of Nuclear 18
- Material, Safety and Safeguards, the Off ice of 19 Enforcement, or the Office of the General Counsel.
20 Therefore, most of the actions described 21 in this directive, and the associated handbook, apply 22 only to those offices.
23 So my question to you, Mr. Case, is, why 24 are you here?
25 (202) 234-4433 MR. CASE:
Because I'm the Pe ti ti on Review NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433

Board Chairman.
2 MR.
MIRANDA:
Did you hear what I just 3
read?
4 MR. CASE:
Mm hmm.
5 MR. MIRANDA:
So why are you here?
6 MR. CASE:
Not to read the responsibility 7
to the Petition Review Board Chairman.
So I'm here as 8
the I need the recommendation to Mr. Dean, and it's 9
Mr. Dean who responds.
So we are fully compliant with 10 the goals and responsibilities defined in the 11 management directive.
So really, when we respond, 12 it'll be Bill Dean that responds, not me.
13 MR. MIRANDA:
Do you work for him?
14 MR. CASE:
No.
15 MR. MIRANDA:
But you know him?
16 MR. CASE:
Yes.
And so what -- just so 17 you understand the reasoning, the reasoning that Bill 18 used, is that he wanted somebody that was not already 19 involved in all the previous activities to do it.
So 20 he was trying to get an independent look.
So that's 21 why he picked me.
22 MR. MIRANDA: And you couldn't find anyone 23 else in NRR?
24 MR. CASE:
They' thought it was best that 25 they searched for somebody outside NRR, rather than - -

WASHINGTON, D.C. 20005-3701 (202) 234-4433
12 1
(Simultaneous speaking) 2 MR.
MIRANDA:
I will request for the 3
record that you put that in your response for an 4
explanation as to why you're finding that.
5 MR. CASE:
Okay.
6 MR. MIRANDA:
Because it is not consistent 7
with what 1 s in the management directive which you just 8
quoted to.
You know, the one that says my Petition is 9
rejected.
10 MR. CASE:
Okay, continue on.
11 MR.
MIRANDA:
I would say I appreciate 12 your comments about my points having merit.
I took 13 great care to make sure that my points were not 14 considered before.
And I think the people here who 15 are familiar with these issues -- and I'm looking at 16 Summer and Josh here -- what's your name?
17 MR. BORROMEO:
I'm Josh.
18 MR. MIRANDA:
Oh you're Josh.
I think on 19 reading the Petition and supplemental portion, I think 20 you will agree that there are a lot of new things in 21 there that were not considered before.
And in fact, 22 the two handouts I provided last time I was here, I 23 know they were not considered before because I created 24 them.
25 (202) 234-4433 And in fact, the little plot I gave you NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
13 1
that showed how
- much flow was coming out of the 2
pressurizer relief
- valves, under water relief 3
conditions, was much, much higher than anything that 4
could be supplied by the emergency core cooling 5
system.
6 That took a lot of work.
I didn't --
I 7
needed a critical flow correlation for that, which I 8
got out at Realat by the way, and adapted it for the 9
PC.
And it was conservative.
The flow that was 10 represented on that curve was saturated flow. Really, 11 it should be subcooled flow, and that would be at 12 least 150 percent higher.
And I know this was not 13 considered before.
14 So my reasoning here is that in order to 15 reject --
in order to reject a petition like this, 16 which has at least 12 errors, and probably as many 17 omissions, most of which are new, to reject a petition 18 like this, if you are truly concerned with protecting 19 the public heal th and safety, you would need to verify 20 that each and every one of them has been considered 21 before, and has been resolved.
22 If there's even one that has not been 23 considered or resolved, you need to consider the 24 Pe ti ti on.
I object strenuously. You' re rejecting the 25 entire Petition because of this overall --
I don't (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
1 know what to call it -- a standard form letter that 2
says, oh we haven't found anything new or significant.
3 Well I can tell you that there are things 4
in there that are new and significant, including the 5
creation of a new accident.
And add the regression 6
and safety margin, and the *filing under oath and 7
affirmation of, no significant safety hazards 8
evaluations, that were false, and I would say these 9
statements are not only false, they're lies, because 10 the people who made these statements and I'm 11 referring to the Exelon engineers and executives --
12 should have known better.
13 They willingly did this. It's not just a 14 typo, because I've seen these no-significant-hazards 15 evaluations.
They always supply license amendment 16 reports, and they all seem to magically come to a 17 conclusion that there is no significant hazard.
And 18 there's lots of explanations as to why, and most of 19 them make sense.
But in this case, they' re just 20
- wrong, and I think that requires an enforcement 21 action.
22 And I suggested some enforcement actions 23 in this Petition which I think were reasonable.
I'm 24 not asking for the shutdown of these plants, although 25 I believe that probably these plants should not have (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
15 1
been licensed in the first place considering the 2
licensing basis that's available today.
3 Well let me go back to this curve I 4
referred to, because I'm rather proud of it. It took 5
a lot of work.
And then there will be here -- I will 6
also talk on the other hand, also in a way that 7
perhaps you haven't heard before.
8 So you recall this curve, and this refers 9
to the statements that Exelon made in their SSAR, 10 which said -- and this is directly from the SSAR --
11 since the cause of the water relief is the ECCS flow, 12 the magnitude of the leak will be less than or 13 equivalent to that of the ECCS.
That is, operation of 14 the ECCS maintains RCS inventory during the postulated 15 event and establis.hes the magnitude of the subject 16 leak.
17 So if this is true, then there is no 18 accident here.
There's nothing to analyze.
There's 19 the
- event, the inadvertent actuation of these 20 currently, to fill in the pressurizer, and currently 21 to discharging water for the relief valves, and 22 currently to the relief valves sticking open, and the 23 resulting flow is no more than the leak.
Therefore, 24 the accident has not progressed to a more severe 25 event.
(202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
16 1
There ' s no need to provide any further 2
information in the SSAR.
The evaluation is done.
But 3
you can see from this curve that it's not true.
4 According to Exelon, the reactor -- the pressurized 5
water reactor that they're operating in Illinois 6
actually the Ford plant used to produce a lot of 7
electrical power these plants can be modeled by the 8
coffee cup.
9 You pour coffee into the cup, you keep 10 pouring it, eventually coffee overruns the brim of the 11 cup, and then from the saucer.
The flow of coffee 12 into the saucer is exactly equal to the flow of coffee 13 coming out of the coffee pot, and into the cup.
This 14 is the coffee cup model.
15 We're talking about a pressurized water 16 reactor at 2250 PSI, with no mention of critical flow.
17 So according to Exelon, this is just a leak.
No loss 18 of coffee accident.
19 So this is another interpretation of their 20 licensing basis.
Well actually there are two.
This 21 interpretation explains it all.
Explains why they 22 don't do the analysis.
They don't have to.
They've 23 explained it.
They don't do the analysis that shows 24 the event will not become a more serious event.
They 25 do an analysis to show that the event will not (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
17 1
overpressurize the reactor cooling system. That's the 2
one where they open the safety valves.
3 And that is a conservative analysis. They 4
don't say it was not necessary to do that analysis, 5
because the charging pumps in question have 6
pressurized the reactor cooling system, simply don't 7
have the head to pressurize the reactor cooling - - the 8
pressures higher than the safety limit.
9 So that analysis was also not necessary.
10 They could have just written a couple of sentences to 11 that ef feet.
So when they do such analysis, the 12 reviewer would have to look at that and question 13 whether or not Exelon knew what they were doing, and 14 whether they should be operating the power plant.
Do 15 they know what kind of equipment they're running?
16 The same thing with the DNV analysis.
1 7 That's another requirement for this event. There must 18 not be any spill damage.
So they do an analysis, and 19 in this case, it's conservative to assume that the 20 pressurizer power-operated relief valves open to keep 21 the pressure down, because that's conservative for 22 fuel cell margin.
You keep the power high and the 23 pressure low.
But one of the consequences of an 24 inadvertent ECCS actuation, is an immediate reactor 25 trip that's part of the sequence.
It happens every (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
18 1
time there's an ECCS actuation.
2 So the reactor trips at time zero.
There 3
is no possibility of damaging any fuel.
They should 4
know this.
They should just say so.
Why do they do 5
an analysis.
We have curves in the licensing basis of 6
the interim DNV ratio, that somehow never dropped 7
below the initial value.
8 Well, I wonder why?
You can't damage the 9
fuel if you' re not generating power.
So if your 10 objective is to protect public heal th and safety, then 11 why didn't you ask questions like this?
12 So my position is that maybe my points 13 have merit, but if there's even one point in there 14 that hasn't been considered and resolved, the Petition 15 needs to be reviewed.
Just one.
And I gave you one.
16 I can give you more.
17 Thank you.
If, on the other hand, your 18 objective is to process the paperwork and get it off 19 your agenda, then just go ahead and reject it.
Just 20 process this just like a lot of other petitions I've 21 seen processed.
22 There's another point which I made the 23 last time, with another curve.
This is not technical 24 at all.
This is simple logic.
You remember this 25 curve? This relates to a design requirement that was (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
19 1
established in 1973, and the licensee committed to 2
meeting it.
All licensees committed to meeting it.
3 It makes sense.
4 It says, AOO Anticipated Occupational 5
Occurrence, AOOs - - shall be accommodated with. Shall 6
be.
Legalese.
That means it's required -- shall be 7
accommodated with, at most, the shutdown of the 8
reactor, with the plant capable of returning to 9
operation after corrective action.
10 I'm not going to worry about the plant 11 being capable of returning to operation after 12 corrective action, because that is subject to a 13 variety of interpretations.
But the first part is 14 explicit.
15 So what happens?
An. AOO has to be 16 accommodated with, at most, a shutdown of reactor. So 17 here we have this curve.
You see the red line on the 18 curve?
This 2400 PSI.
This is the high-pressure 19 reactor curve set point.
20 If you get to the right of that curve, if 21 the pressure gets above 2400 PSI and you have to open 22 the safety valves -- which open, by the way, at 2500 23 PSI -- this is no longer an AOO.
It's something else.
24 It's something worse.
You've gotten to a place where 25 you violated this requirement.

So to put it simply in logical terms, if 2
this is an AOO, it'll be accommodated with a reactor 3
trip.
Do you agree with that?
Does anybody agree 4
with that?
If A, then B.
If it's an AOO, then B, 5
it's accommodated with a reactor trip.
This is what 6
the standard says, it's 1973.
7 If it's an AOO, you can deal with it with 8
a reactor trip.
Is that true?
9 MR. CASE:
I turn to my technical friend, 10 generally true.
11 UNIDENTIFIED SPEAKER:
He never says --
12 MR. MIRANDA:
Is it true? If a -- if it's 13 an AOO, then B, it's accommodated with a reactor trip.
14 That's the premise.
15 UNIDENTIFIED SPEAKER:
Proceed on topic.
16 MR. MIRANDA:
That means let me go to the 17 next part then.
If the premise is true -- if A, then 18 B -- then the contrapositive is also true -- if not B, 19 then not A.
If it can't be accommodated with a 20 reactor trip --
for example, by opening the safety 21 valves -- if it can't be accommodated with a reactor 22 trip, then it's not an AOO.
If it's not an AOO, then 23 what is it?
24 It has to be either a Condition 3 or a 25 Condition 4 event.
There's nothing else that's (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
21 1
possible.
You've violated the criterion.
If you're 2
opening a safety valve, you've violated the criterion.
3 That's the end of that analysis. The licensee has not 4
met its obligation to meet its design requirement.
5 So -- I've seen a lot of discussion. I've 6
seen a lot of consideration when I was working here, 7
and after I left, actually.
A lot of people -- a lot 8
of smart people -- worrying about whether the safety 9
valves could be qualified for water relief.
And my 10 question is, maybe they can, although I haven't seen 11 anyone successfully do it, and that includes Exelon.
12 Maybe they can, but it doesn't matter, 13 because these valves are not going to* be used to 14 respond to an AOO.
If you're opening these valves, 15 you've already violated the_escalation criteria.
16 But it doesn't matter to me.
These 17 valves, by the way, are -- since they are designed to 18 operate, they're designed to open when the RCS reaches 19 its design pressure, 2500 PSI.
And they're designed 20 to keep the peak pressure to below the over-pressure 21 limit, which is 110 percent of RCS design pressure, at 22 2750.
And these are big valves, and they do the job 23 very well by relieving steam.
24 And they're qualified to relieve steam.
25 They will (202) 234-4433
- open, you will
- see, NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 and prevent (202) 234-4433
22 1
overpressure.
That's their design requirement and 2
they do it well.
But they only do this maybe once in 3
a plant's lifetime, because that's about as often as 4
you're going to get a
Condition 3
event.
A 5
Condition 4 event should not happen at all.
6 So these valves open once.
In a car, 7
these values would be airbags, and the pressurizer, 8
power-operated relief valves, would be seatbelts. You 9
use the seatbelts everyday.
They protect you in* the 10 rough stops or in fender benders.
But those airbags?
11 You use them only once.
The safety valves are used 12 only once.
13 They don't even need to be -- they don't 14 even need to recede.
They've accomplished their 15 safety function by opening and keeping the pressure 16 below the overpressure limit.
That's it.
They're 17 done.
They can stay open.
Do you have a locum? Sure 18 you do.
It can be as big as a three-part, seven-inch 19 brake.
Hot leg brake. That's what these - - these are 20 Crosby M orifice valves. Their flow area is 3.6 square 21 inches times three.
That amounts to about 3.7 inch 22 diameter brake, hot leg. Do you care? You're already 23 into a Condition 4 event.
You've got other things to 24 worry about.
25 So for Exelon to come in to make a license (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
23 1
amendment request for a power upgrade, and represent, 2
or to of fer more information that they' re protected by 3
pressurizing safety valves, just doesn't make sense.
4 They made a mistake, the NRC staff made a 5
mistake in approving it, and the NRC staff tried to 6
correct its mistake.
They were prevented.
I mean 7
that's --
8 So I would say probably the power-operated 9
relief valves are -- they are a control-grade system, 10 and a lot of people have made the mistake of assuming 11 that control-grade systems don't operate in a safety 12 analysis.
That's not always true.
They do operate 13 when it's conservative, in the DNV analysis.
14 As I said before, you need to keep the 15 pressure low and the power high.
That degrades the 16 thermal margin.
To keep the pressure low, reduce the 17 power-operated relief valves.
We also use a
18 pressurizing spray.
1260.
It's both sides, by the 19 way.
That's got three power-operated relief valves.
20 These plants are referred to as full-load 21 rejection plants.
They are capable of keeping the 22 reactor online if the turbo trips at full power.
They 23 have utmost relief capacity, and steam.
24 So as I said, I'm not going to go through 25 everything again.
You've seen it.
You've read it.

WASHINGTON, D.C. 20005-3701 (202) 234-4433
24 1
So that's my position.
If there's anything in here 2
that has not been seen before, that has not been 3
considered and resolved, then you need to go back and 4
review this Petition.
5 Now if it's true that you have reviewed 6
everything, considered it, and resolved it, then I 7
would want to see each and every one of my points --
8 and I believe there's something like 12 errors, and 9
maybe another seven or eight omissions --
I want to 10 see evidence of that.
I want to see an Adams.
11 reference.
Yes, we considered this and this is the 12 way we resolved it.
13 And I can tell you, just from the chart's 14 licensing basis, which I have in front of me, that 15 that little curve I showed you is the -- it showed the 16 flow corning out of the pressurizer was much, much 17 higher than the flow going into it, and that's based 18 upon the statement that Exelon made in SSAR, that it's 19 defined as a leak.
I can read it again, but you know 20 what it is.
21 That statement -- I 'rn looking it right now 22 in Revision 15 of their SSAR, it's right here, it's 23 dated December 2014.
So how did you resolve this?
I 24 think you go back to Exelon and say, well no, the 25 staff doesn't agree with this statement, and if this (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
25 1
statement is not true, you're going to have to do an 2
analysis.
You've going to have to show compliance 3
with the design requirements. You' re going to have to 4
do an analysis of the inadvertent ECCS system 5
actuation.
6 You have to do that analysis using force, 7
assuming the pores open, because a pore that doesn't 8
open can't fail open. That's a convenient way to show 9
that the pore is not going to fail open.
Just don't 10 assume it opens.
This is begging the question, which 11 I mentioned last time, is it circular reasoning?
12 And I'm surprised that the NRC staff could 13 accept this.
You don't need to be an engineer to see 14 this.
Anybody with some level of literacy can see 15 this. You can't assume the outcome.
AOO doesn't mean 16 assumed outcome outcome.
You have to open that port, 17 and they show it won't stay open.
18 Generally, this has been done by many 19 licensees, by showing that when the ECCS system is 20 actuated, it fills the pressurizer at a rate that 21 takes more than ten minutes to fill the pressurizer, 22 and ten minutes has been accepted by the NRC as 23 sufficient time for the operator to diagnose the 24 condition, and then go ahead and shut off the ECCS 25 flow.

But some plants had trouble meeting that 2
ten minute time requirement.
So they've done other 3
things, and -- if a plant can't meet that ten minute 4
requirement, it might have to do some kind of hardware 5
modification, and the one I've seen used most often is 6
to qualify the pores for the water filter.
7 And I can -- I know it because six plants 8
that have done this -- it's not a very hard thing to 9
do.
I've done it myself. I've worked as a contractor 10 at Salem in 1996 and '97, wherein they qualified their 11 relief valves for water leak.
I was involved in that.
12 I
wrote the 'license amendment request.
It was 13 approved by the NRC in 1997.
14 Salem, today, can go ahead and state that 15 they have met the design requirement upon 16 installation. They can go ahead and open those pores, 17 pass water through them, and then assume that they'll 18 recede properly, because they're qualified to do that.
19 Those pores are qualified for water relief.
They 20 discharge piping downstream of the pores.
It's 21 qualified to support the weight of water passing 22 through them. Their lock valves are qualified to stop 23 water flow.
24 Their automatic control-system circuitry 25 has been upgraded to Class 1-E.
They've removed all (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
27 1
of the single point failure vulnerabilities. And they 2
verified that they have sufficient power - - this would 3
be either air or electric - -
they have sufficient 4
power to stifle those pores as many times as 5
necessary.
6 And Salem did this, by the way, because 7
they had two events in 1994, where they filled the 8
pressurizer, and passed water through, and cycled them 9
more than 200 times.
They were fined for this.
So 10 they took this measure in '97 to qualify those pores.
11 Diablo Canyon qualified those pores.
12 Lipscomb qualified their pore~. I think Callaway did 13 as well.
And along comes Exelon, and they say, well 14 we're not going to use our pores, we're going to use 15 our safety valves, and they're qualified for water 16 relief.
And yet -- and in every test show that, re 17 reference XYZ, which they specified - - it was cited in 18 their license amendment request.
19 I looked for that.
I found that report.
20 That report explicitly stated, Inspection 4.2.3, that 21 those tests were not done.
They said -- it said so in 22 the report, it was not necessary to do those tests.
23 They didn't do them, because at that 24 time -- it was in the '80s -- Exelon was calling that 25 their pressurizer would fill any sinker than about 20 (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
28 1
minutes.
2 So there was plenty of time for the 3
operator to shut off the ECCS
- flow, prevent the 4
pressurizer from filling, and thereby guaranteeing 5
that any flow through those pores would be only steam.
6 And with only steam relief, those pores can be relied 7
upon to recede.
There would be no development of a 8
more serious event.
9 And for your information, Diablo Canyon 10 tried to go this way as well.
They tried to qualify 11 their safety valves for water relief, and found that 12 tests would not support their approach.
The water 13 being relieved was just too cold, so the valves were 14 not qualified for water relief.
They withdrew their 15 license amendment request, and instead qualified to 16 relief valves.
That's on record too.
17 So all of this work that the NRC has been 18 doing to help Exelon qualify their safety valves for 19 water relief, is not relevant in the slightest.
It 20 doesn't matter what those safety valves do, you' re not 21 supposed to period.
22 So that's all I have to say.
23 MR. CASE:
Okay, thanks for that.
I took 24 some notes, so we'll take a look at those things.

questions for Mr. Miranda?
2 MR. BILLERBECK:
So this is John Borromeo.
3 So Sam, you're familiar with the Byron/Braidwood fact 4
sheet, all the documentation association with that 5
leak.
Can you discuss a little bit --
what is the 6
difference between your 2.206 and the Byron/Braidwood 7
fact sheet that's out there now?
8 MR.
MIRANDA:
Good question.
I was 9
careful when I wrote that 2.206 not to mention the 10 fact sheet.
I wanted the 2.206 to stand alone as an 11 enforcement action.
So as it stands -- as the current 12 situation is, Exelon is considered by the NRC 13 thanks to the EDO's decision is considered by the 14 NRC to have complied with the no-escalation design 15 requirement.
16 So in terms of licensing, they've been --
17 basically they've been given a pass.
Okay? The 2.206 18 Petition that I wrote shows that that pass was not 19 justified.
The decision was wrongly made, because 20 there was -- the licensing basis was rife with errors 21 and omissions.
22 And that at the basis of the statement of 23 considerations lurking on in re: 1409, that says, well 24 the NRC can't just propose a compliance backf it 25 because it changed its mind, or its position, and to (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
30 1
go this way, rather than that way.
2 No, they have to find errors, either in 3
the licensing basis -- errors made by the licensee 4
and regrettably, sometimes errors made by the staff, 5
and they need to be corrected.
And that's what the 6
Petition 2.206 does.
It shows every part of that 7
licensing basis that was deficient.
8 Sometimes there were analyses that were 9
missing, and sometimes there were analyses that were 10 just wrong, and I gave an example of that last time I 11 was here.
They have a statement event in this SSAR, 12 and I'm looking at it right now.
The statement says, 13 oh we don't need to look at this inadvertent ECCS 14 actuation event because that's already been analyzed 15 as well in the SSAR.
16 That approach is by the way, that 17 approach is quite valid. It's mentioned in Reg. Guide 18 1.70.
You don't have to analyze every sub-case of 19 every case.
If you can envelope cases, that's fine.
20 But in this case, what Exelon did was point to another 21 Reg. Guide 1.70 analysis.
22 It's in standard content and format of 23 SSAR for inadvertent see-no, for ECCS 24 malfunction chemical volume and control system 25 malfunction.
Okay?
(202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

This is another mass addition event that 2
should be analyzed in Chapter 15. 5, I think.
But 3
there are two cases here, and it's mentioned twice in 4
Reg. Guide 1. 7 0.
Once was a mass addition event, 5
which builds the pressurizer, and causes the relief 6
valves to open and pass water, leading to the more 7
serious event.
And then in another section of Reg.
8 Guide 1.70, the same event was evaluated as a
9 reactivity anomaly.
10 And this is when the CDCS malfunction 11 inserts clean water into the reactor cooling system, 12 and causes a
reactivity insertion.
That's a
13 completely different analysis. It's not done with the 14 same computer codes, it's not done according to the 15 same criteria, it has nothing to do with the mass 16 addition event.
17 Exelon, nevertheless, puts it into their 18 SSAR as a bounding event, and the NRC staff accepted 19 it.
20 MR. BILLERBECK:
And that's a delta from 21 your original backfit on the reactor systems event, 22 that something different in a petition, that's not in 23 the original backfit that was created from NRR.

2 MR. MIRANDA:
Yes.
3 MR. BILLERBECK:
what's the difference 4
from an original backfit, and a 2.206?
5 MR. MIRANDA:
I mentioned this case in 6
I think in a draft of a RIS, for example.
7 MR. BILLERBECK:
Okay.
8 MR. MIRANDA: It was not mentioned in this 9
last 2.206 Petition.
That's why I brought it up.
I 10 said, this is something new, I brought it up the last 11 time I was here.
But it's common.
I've seen other 12 licensees do the same thing.
It indicates to the 13 reviewer, that they really don't understand what's in 14 Chapter 15.
They don't know why these analyses are 15 done, and what the referenced criteria are, which I 16 think -- if I were reviewing -- insert here by the way 17 is still in here.
It's in the same revision 18 December 2014.
It's still in here.
19 So why is it there?
The reviewers ought 20 to be asking basic questions of, other licensees that 21 does it. The questions you might ask an operator when 22 he's taking his license exam, do you know your plant's 23 design, what equipment you're operating, and what's 24 precautions you need 'to take?
Again, I did not ask 25 for this test to shut down, but these things need to (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

be corrected.
2 MR. BILLERBECK:
Sam? How about this one?
3 Are you aware of any testing that has occurred, in 4
essence, since the backfit appeal, that would indicate 5
how SR Vs would actually operate under water 6
conditions?
7 MR. MIRANDA:
As far as SRVs?
8 MR.
BILLERBECK:
Yes.
SR Vs
- sporks, 9
or -- the Safety Relief Valves.
10 MR. MIRANDA:
Safety relief valves. Okay.
11 Since the appeal?
No.
These test valves, they go 12 back to the *sos.
They go back -- a lot of them were 13 done in response to Three Mile Island.
14 And from test results I've seen, they go 15 back, they were concentrated on relief valves testing, 16 and there were also some safety valve tests.
But 17 those safety valve tests were different. Those safety 18 valve tests were designed to model a feedline break, 19 which would produce a much hotter flow -- hot water 20 flow through the valves, because the typical 21 feedline break analysis in Chapter 15 will show that 22 the safety valves open underneath water.
23 And that's okay, because when you're in a 24 Condition 4 event, where are you going to escalate to?
25 Condi ti on 5?
(202) 234-4433 It's what happens during a feedline NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

break.
It's -- Condition 4's not supposed to happen 2
anyway.
Then you have --
you have other things to 3
worry about.
You're evacuating the exclusion zone, 4
and the feedline break.
5 But there were some tests that go back to 6
the '80s, testing safety valves under feedline break 7
conditions.
8 MR. BILLERBECK:
but no new information 9
that you're aware of?
10 MR. MIRANDA:
No.
11 MR. BILLERBECK:
Okay.
Are you aware of 12 any events that have occurred since the backfit 13 appeal, that would illuminate how plant response would 14 be for an inadvertent operation of a POR?
15 MR. MIRANDA:
I'm not aware of any --
I 16 haven't been following it, so I'm not aware of any 17 recent events, but there are plenty of events in the 18 operating history that show inadvertent ECCS 19 actuations.
Okay? It's the second most common event 20 after the reactor trip.
21 And sometimes, even a reactor trip will 22 cause a safety system actuation that's not necessary.
23 It's called a trip with complications.
So it's very 24 common.
And usually it doesn't amount to much, and 25 there's a difference here that probably we should take (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

note of.
2 There's IRL -- In Real Life, IRL -- and 3
there's licensing space, and in licensing space, a 4
pressurizer power-operated relief valve, or any valve, 5
that's not designed for water relief, if it opens and 6
removes water, it's a (inaudible).
7 In real life we saw that, for example, in 8
1994 when Salem had those two events, their relief 9
valves opened to relieve water from the (inaudible).
10 Also in real life, we saw them debate, especially into 11 the relief valve opened and relieve steam, and stuck 12 open.
13 And we see that very of ten in the 14 operating experience.
I saw that very often with D&W 15 design plants, Three Mile Island, especially. Exelon, 16 by the way, operates Three Mile Island, Unit 1.
17 So in the real world, a relief valve that 18 opens for any condition, it's a spurious opening, or 19 it's loss of load, or a turbine trip, or loss of 20 feedwater, anything that causes the primary system to 21 heat up and pressurize to a level that will open the 22 relief valves, that could be enough to cause a relief 23 valve to stick open. But that's not something you can 24 analyze for.
25 In the real world, by the way, the best (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433
36 1
example I think I have would be the Beznau incident, 2
which happened in 1974 in Switzerland, and there they 3
had a turbine trip.
Beznau is a -- the unit that has 4
two turbines.
One of the turbines tripped.
Well 5
that's equivalent to a 50 percent load rejection.
6 A 50 percent load rejection ought to be 7
able to a plant ought to be able to tolerate that 8
without tripping.
It should be able to reject 5 0 9
percent of a load.
In this case it didn't.
It 10 tripped, and the pressurizer pressure went up, and the 11 relief valve opened, and it may have relieved water, 12 or just steam.
13 It's not really known exactly what came 14 out of the valve.
But the point is, that the valve 15 stuck open, and the operators of Beznau realized the 16 valve was stuck open, and he closed the blocked valve.
17 So they -- in the real world, that's what 18 you would do.
You would close the blocked valve. But 19 as I said in the RIS of 2005, Westinghouse was 20 advising its customers that opening a blocked valve 21 or opening a relief valve and having it stick open is 22 not a concern, because you can always close the 23 blocked valve.
24 Well that's true.
In the real world, 25 that's what operators would do.
They would close the (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

blocked valve. However, if you're closing the blocked 2
- valve, you' re not mitigating an inadvertent ECCS 3
actuation.
You are mitigating a local.
It's proof 4
that you've already violated the criteria.
5 MR. CASE:
Any other questions?
6 UNIDENTIFIED SPEAKER:
Here.
7 MR.
CASE:
How about any headquarters 8
staff on the phone have any questions for Mr. Miranda?
9 Okay, you have questions?
Oh wait a minute.
10 MR. BILLERBECK:
I say no questions. This 11 is John Billerbeck.
12 MR. CASE:
Thanks.
How about the regions?
13 Any questions from the regions?
Okay, good.
How 14 about the -- the licensees are not on the line, right?
15 UNIDENTIFIED SPEAKER:
They might be.
16 MR. CASE:
Okay.
How about the licensee?
17 Any questions from the licensees? Okay, we have a few 18 people from the public before I conclude the meeting.
19 Member of the public may provide comments regarding 20 the Petition, and ask questions about the petition 21 process.
22 Whatever was stated at the opening, the 23 further intention is to provide an opportunity for the 24 Petitioner or the public to question or examine the 25 PRB regarding the merits of the Petition request.

Go ahead Dave.
All right.
2 MR. LOCHBAUM:
I've got a question and a 3
couple of observations.
4 MR. CASE:
Okay.
5 MR.
LOCHBAUM:
Do you have a ballpark 6
timing for the NRC response letter to Mr. Miranda?
7 MR.
CASE:
I don't know.
I guess you 8
could --
9 (Simultaneous speaking.)
10 MR. WEIBE: It will take us a while to get 11 the transcript back.
Then we have to take a look at 12 the transcript, meet as a PRB, a lot depends on the 13 consensus of the PRB, and if we're in alignment on 14 whatever that decision may be.
So I would say we 15 probably can come to that decision in about three 16 weeks, and then maybe another couple of weeks to get 17 the document out.
So I would estimate at this point 18 it'd be five weeks ballpark.
19 MR. LOCHBAUM:
Thank you.
I would echo a 20 point that Mr. -- Mr. Bannister's punch letter said he 21 explicitly expressed that the reason for rejecting it 22 is because it's no new information that you explicitly 23 go to, to find Mr. Miranda's Petition, and show where 24 that has been addressed, without making the argument, 25 because I don't know if you're aware, the Inspector (202) 234-4433 NEAL R.

General is initiating an audit of the 2.206 process.
2 And hopefully soon Mr. Miranda's Petition 3
that we find in new information that the rejection 4
letter hadn't explained or addressed. We're going to 5
go to the Inspector General and say they didn't follow 6
the process.
We might do that anyway, but what we 7
could definitely do that, at a meeting with IG next 8
Monday.
9 But I
don't expect a letter by next 10 Monday, but that audit is just starting.
So we can 11 inform them.
12 MR.
MIRANDA:
Just to be accurate, the 13 criteria is, new and significant information.
So 14 that's the cri-so it's bull.
And so we do go 15 through the Petition with the famous fine-toothed 16
- comb, looking for new.
It has to be new and 17 significant.
18 MR. WEIBE:
Any other comments? Keep them 19 coming Dave.
You're good.
20 MR. CASE:
Explain what we're looking for 21 and what we'll do, because I don't see it.
22 MR. WEIBE:
Okay.
23 MR. MIRANDA:
And let me say this about 24 significant, because I know significant is one of 25 those subjective terms that, the definition depends on (202) 234-4433 NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
WASHINGTON, D.C. 20005-3701 (202) 234-4433

who you ask.
So all I can say is, when you look at 2
5092 --
3 (Telephonic interference) 4
-- significant, look at 5092, where you're 5
supposed to write something for the no-significant-6 hazards evaluation.
So if, as I have done in the 7
Petition or enforcement, if I have found a case where 8
there could be a significant hazard -- okay, in other 9
words, if you can't answer, no, to the three questions 10 that are 5092, then that's significant. If there's a 11 reduction in safety margin, or if there's an increase 12 in probability, or if there's a new accident, those 13 are all significant. And if that's the case, then you 14 answer, yes, to those appropriate questions.
And so 15 by definition, that's significant.
16 MR.
WEIBE:
Any other questions?
Any 17 seconds?
- Lee, how's everybody doing?
Okay.
18 Everybody okay?
Okay.
Thanks - -
