(RITSTF)

==

were

November

==

10,

==

1999.

==

The

==

The

==

meetings

==

were

==

a

==

continuation

==

of

==

earlier

==

meetings

==

where

==

the

==

NRC

==

staff

==

and

==

the

==

industry

==

discussed

==

ongoing

==

risk-

==

informed

==

technical

initiatives

==

and

==

the

creation

==

of

==

a

==

fully

==

risk-informed

==

set

==

of

==

standard

==

technical

==

specifications

==

(STS).

==

The

==

main

==

purpose

==

of

==

the

==

October

==

6-7

==

meeting

==

was

==

to

==

have

==

a

==

more

==

detailed

==

discussion

==

of

==

the

==

probabilistic

==

risk

==

analysis

==

(PRA)

==

work

==

done

==

to

==

support

==

the

==

current

==

technical

==

specification

==

(TS)

==

initiatives

==

being

==

prepared

==

for

==

submittal

==

to

==

the

==

staff.

==

There

==

was

==

limited

==

RITSTF

==

representation

==

at

volunteered

==

San

(SONGS)

==

to

==

be

==

the

==

industrys

==

lead

==

plant

==

for

==

the

==

majority

==

of

==

the

==

seven

==

initiatives

==

currently

==

being

==

pursued

==

by

==

the

==

RITSTF.

==

These

==

include:

==

1.

==

Define

==

preferred

==

end

==

states

==

for

==

TS

==

actions

==

(e.g.,

==

hot

==

shutdown

==

vs.

==

cold

==

shutdown)

==

2.

==

Increase

==

the

==

time

==

allowed

==

to

==

delay

==

entering

==

required

==

actions

==

when

==

a

==

surveillance

==

is

==

missed

==

3.

==

Modify

==

existing

==

mode

==

restraint

==

logic

==

to

==

allow

==

use

==

risk

==

assessments

==

for

==

entry

==

into

==

limiting

==

conditions

==

for

==

operation

==

(LCOs)

==

with

==

inoperable

==

equipment

==

based

==

on

==

low

==

risk

==

4.

==

Develop

==

a

==

risk-informed

==

extension

==

of

==

current

==

allowed

==

outage

==

times

==

based

==

on

==

a

==

configuration

==

risk

==

management

==

program

==

(CRMP)

==

5.

==

Optimize

==

surveillance

==

requirements

==

(SRs)

==

6.

==

Modify

==

LCO

==

3.0.3

==

actions

==

and

==

timing

==

by

==

extending

==

minimum

==

time

==

to

==

begin

==

LCO

==

3.0.3

==

shutdown

==

from

==

1

==

hour

==

to

==

24

==

hours

==

and

==

allowing

==

for

==

a

==

risk-informed

==

evaluation

==

to

==

determine

==

whether

==

it

==

is

==

better

==

to

==

shut

==

down

==

or

==

continue

==

to

==

operate

==

7.

==

Define

==

actions

==

to

==

be

==

taken

==

when

==

equipment

==

is

==

not

==

operable

==

but

==

is

==

still

==

functional

==

The

==

staff

==

and

==

the

==

industry

==

discussed

==

the

==

meaning

==

of

==

the

==

term

==

risk-informed

==

as

==

it

==

relates

==

to

==

regulatory

==

applications.

==

The

==

industry

==

stated

==

that

==

it

==

was

==

their

==

general

==

philosophy

==

to

==

use

==

qualitative

==

risk

==

assessments

==

where

==

they

==

believed

==

the

==

benefits

==

of

==

a

==

proposed

==

change

==

were

==

obvious,

==

and

==

to

==

use

==

quantitative

==

assessments

==

where

==

the

==

outcome

==

was

==

not

==

as

==

obvious.

==

The

==

industry

==

also

==

stated

==

that

==

they

==

take

==

into

==

account

==

other

==

aspects

==

such

==

as

==

defense

==

in

==

depth

==

and

==

safety

==

margins

==

when

==

considering

==

a

==

proposed

==

change.

==

The

==

industry

==

believed

==

such

==

an

==

approach

==

was

==

consistent

==

with

==

the

==

guidance

==

in

==

Regulatory

==

Guide

==

1.174,

==

An

==

Approach

==

for

==

Using

in

on

the

Basis,

==

to

==

use

==

PRA

==

to

==

improve

==

decision

==

making

==

and

==

regulatory

==

effectiveness.

==

The

==

staff

==

reserved

==

judgement

==

of

==

such

==

an

==

approach

==

noting

==

that

==

benefits

==

that

==

are

==

obvious

==

to

==

one

==

person

==

or

==

group

==

might

==

not

==

be

==

obvious

==

to

==

another.

==

SONGS

==

representatives

==

then

==

presented

==

some

==

details

==

regarding

==

their

==

PRA

==

work

==

in

==

support

==

of

==

some

==

of

==

the

==

RITSTF

==

initiatives.

==

The

==

San

==

Onofre

==

presentations

==

are

==

contained

==

in

==

Enclosure

==

3.

==

The

==

SONGS

==

representatives

==

presented

==

information

==

regarding

==

their

==

living

==

PRA

==

and

==

Safety

==

Monitor,

==

including

==

the

==

full

==

power,

==

transition,

==

and

==

low

==

power

==

and

==

shutdown

==

risk

==

models.

==

The

==

SONGS

==

representatives

==

stated

==

that

==

they

==

had

==

their

==

own

==

transition

==

model

==

development

==

document

==

1

==

Enclosure

==

that

would

likely

==

be

referenced

or

==

included

==

in

==

the

==

SONGS

==

plant-specific

==

submittal

==

for

==

Initiative

==

  1. 1.

==

The

==

staff

==

and

==

the

==

RITSTF

==

discussed

==

some

==

specific

==

submittal

==

and

==

implementation

==

and

==

technical

==

issues

==

related

==

to

==

a

==

few

==

of

==

the

==

initiatives.

==

With

==

regard

==

to

==

Initiative

==

  1. 1

==

related

==

to

==

safe

==

end

==

states,

==

the

==

RITSTF

==

indicated

==

that

==

the

==

Combustion

==

Engineering

==

Owners

==

Group

==

(CEOG)

==

was

==

preparing

==

a

==

draft

==

report

==

to

==

support

==

this

==

initiative

==

and

==

that

==

the

==

report

==

would

==

accompany

==

an

==

industry

==

request

==

for

==

a

==

generic

==

change

==

to

==

the

==

STS.

==

The

==

RITSTF

==

indicated

==

that

==

changes

==

to

==

the

==

TS

==

end

==

states

==

would

==

be

==

proposed

==

for

==

the

==

vast

==

majority

==

of

==

LCOs

==

in

==

the

==

STS.

==

The

==

RITSTF

==

indicated

==

that

==

uncertainties

==

and

==

sensitivities

==

of

==

PRA

==

results

==

will

==

be

==

investigated.

==

The

==

group

==

discussed

==

that

==

additional

==

known

==

shutdown

==

issues

==

which

==

may

==

impact

==

the

==

results

==

(e.g.,

==

external

==

events

==

and

==

boron

==

dilution)

==

should

==

be

==

addressed.

==

Representatives

==

from

==

the

==

Boiling

==

Water

==

Reactor

==

Owners

==

Group

==

(BWROG)

==

stated

==

that

==

they

==

are

==

still

==

considering

==

this

==

initiative

==

and

==

that

==

the

==

risk

==

of

==

operating

==

in

==

hot

==

shutdown

==

and

==

in

==

cold

==

shutdown

==

is

==

relatively

==

the

==

same,

==

whereas

==

for

==

the

==

pressurized

==

water

==

reactors

==

there

==

appears

==

to

==

be

==

a

==

clear

==

risk

==

benefit

==

to

==

operating

==

in

==

hot

==

shutdown

==

in

==

most

==

cases.

==

They

==

indicated

==

that

==

they

==

would

==

be

==

more

==

interested

==

in

==

changing

==

the

==

current

==

TS

==

to

==

allow

==

them

==

to

==

use

==

PRA

==

in

==

deciding

==

whether

==

to

==

stay

==

at

==

power

==

or

==

shut

==

the

==

reactor

==

down.

==

They

==

also

==

indicated

==

that

==

they

==

may

==

be

==

interested

==

in

==

extending

==

the

==

time

==

requirements

==

for

==

going

==

to

==

cold

==

shutdown.

==

This

==

would

==

allow

==

them

==

to

==

operate

==

longer

==

in

==

hot

==

shutdown

==

conditions.

==

The

==

BWROG

==

is

==

considering

==

a

==

pilot

==

plant

==

for

==

this

==

issue.

==

The

==

RITSTF

==

and

==

the

==

staff

==

discussed

==

how

==

the

==

SONGS

==

assessment

==

results

==

for

==

Initiative

==

  1. 1

==

could

==

be

==

applied

==

to

==

other

==

plants.

==

The

==

Westinghouse

==

Owners

==

Group

==

(WOG)

==

indicated

==

that

==

they

==

would

==

attempt

==

to

==

show

==

how

==

the

==

SONGS

==

results

==

apply

==

using

==

qualitative

==

assessments

==

and

==

comparisons,

==

and

==

that

==

they

==

did

==

not

==

plan

==

to

==

perform

==

any

==

further

==

plant-specific

==

analyses.

==

The

==

Babcock

==

and

==

Wilcox

==

Owners

==

Group

==

indicated

==

that

==

they

==

intended

==

to

==

pursue

==

a

==

similar

==

approach.

==

The

==

group

==

indicated

==

that

==

they

==

could

==

use

==

the

==

SONGS

==

model

==

to

==

help

==

develop

==

sensitivity

==

studies

==

to

==

address

==

some

==

of

==

the

==

design

==

differences

==

between

==

the

==

plants.

==

The

==

staff

==

stated

==

that

==

they

==

could

==

not

==

make

==

any

==

definitive

==

decisions

==

on

==

what

==

type

==

of

==

submittals

==

they

==

would

==

find

==

acceptable

==

and

==

that

==

the

==

burden

==

of

==

proof

==

of

==

similarity

==

to

==

the

==

CEOG

==

work

==

would

==

rest

==

with

==

the

==

other

==

owners

==

groups.

==

With

==

regard

==

to

==

Initiative

==

  1. 2

==

related

==

to

==

missed

==

SRs,

==

the

==

group

==

discussed

==

the

==

PRA

==

aspects

==

of

==

that

==

initiative.

==

In

==

order

==

to

==

assess

==

the

==

increase

==

in

==

risk

==

it

==

is

==

necessary

==

to

==

make

==

an

==

assumption

==

about

==

the

==

frequency

==

of

==

the

==

various

==

expected

==

missed

==

surveillances.

==

This

==

requires

==

an

==

understanding

==

of

==

the

==

reasons,

==

the

==

nature

==

and

==

circumstances

==

under

==

which

==

surveillances

==

are

==

missed.

==

The

==

RITSTF

==

pointed

==

out

==

that

==

even

==

if

==

the

==

failure

==

rate

==

of

==

a

==

component

==

is

==

doubled,

==

due

==

to

==

the

==

missed

==

surveillance

==

on

==

that

==

component,

==

the

==

plant

==

risk

==

would

==

not

==

be

==

affected

==

significantly.

==

The

==

staff

==

agreed

==

that

==

most

==

likely

==

the

==

risk

==

increase

==

would

==

not

==

be

==

significant

==

unless

==

some

==

licensees

==

abuse

==

the

==

proposed

==

flexibility.

==

The

==

development

==

and

==

implementation

==

of

==

an

==

appropriate

==

regulatory

==

oversight

==

process

==

could

==

address

==

this

==

issue.

==

The

==

industry

==

and

==

the

==

staff

==

agreed

==

that

==

the

==

staffs

==

review

==

of

==

this

==

issue

==

would

==

involve

==

more

==

of

==

a

==

policy

==

decision

==

than

==

a

==

technical

==

decision.

==

With

==

regard

==

to

==

Initiative

==

  1. 3

==

related

==

to

==

mode

==

restraints,

==

SONGS

==

has

==

been

==

studying

==

this

==

issue

==

by

==

comparing

==

the

==

relative

==

importance

==

of

==

functions

==

and

==

associated

==

systems

==

at

==

various

==

modes

==

of

==

operation.

==

The

==

proposed

==

change

==

would

==

allow

==

a

==

licensee

==

to

==

use

==

a

==

CRMP

==

to

==

decide

==

whether

==

to

==

enter

==

into

==

a

==

mode

==

or

==

other

==

specified

==

condition

==

within

==

the

==

applicability

==

with

==

inoperable

==

equipment.

==

The

==

staff

==

agreed

==

that

==

the

==

study

==

of

==

conditions

==

and

==

risks

==

associated

==

with

==

various

==

likely

==

transitions

==

could

==

help

==

focus

==

the

==

issue

==

and

==

identify

==

an

==

appropriate

==

regulatory

==

oversight

==

mechanism.

==

With

regard

==

to

==

Initiative

==

  1. 6

==

related

==

to

==

changes

==

to

==

LCO

==

3.0.3,

==

the

==

RITSTF

==

stated

==

that

==

this

==

initiative

==

is

==

very

==

closely

==

tied

==

to

==

the

==

maintenance

==

rule

==

as

it

addresses

==

what

actions

to

take

==

for

==

a

loss

==

of

safety

function.

==

The

industry

==

indicated

==

that

==

the

frequency

==

of

plant

==

conditions

==

for

==

which

==

this

TS

change

is

applicable

is

low.

==

The

mentioned

that

the

and

study

of

examples

==

of

specific

that

would

drive

the

to

shutdown,

including

associated

risks,

==

could

==

help

focus

==

the

==

The

discussed

the

process

for

to

adopt

approved

to

the

==

The

being

considered

==

to

==

make

adoption

==

of

==

such

changes

==

more

efficient.

==

Finally,

==

the

==

group

==

discussed

==

submittal

==

schedules

==

for

==

some

==

of

==

the

==

initiatives.

==

The

==

RITSTF

==

stated

==

that

==

they

==

expected

==

to

==

submit

==

Initiatives

==

  1. 2

==

and

==

  1. 3

==

to

==

the

==

staff

==

around

==

October

==

30,

==

1999,

==

and

==

that

==

they

==

might

==

be

==

able

==

to

==

submit

==

some

==

of

==

their

==

PRA

==

assessment

==

for

==

Initiative

==

  1. 1

==

by

==

December

==

31,

==

1999.

==

The

==

RITSTF

==

stated

==

that

==

Initiatives

==

  1. 4

==

and

==

  1. 6

==

would

==

come

==

sometime

==

in

==

2000.

==

The

==

November

==

10,

==

1999

==

meeting

==

was

==

a

==

meeting

==

of

==

the

==

full

==

RITSTF

==

to

==

discuss

==

high-level

==

objectives

==

and

==

the

==

status

==

of

==

the

==

current

==

initiatives.

==

All

==

presentations

==

for

==

the

==

meeting

==

are

==

contained

==

in

==

Enclosure

==

4.

==

The

==

staff

==

opened

==

the

==

meeting

==

with

==

a

==

general

==

discussion

==

of

==

the

==

status

==

of

==

risk-informed

==

regulatory

==

activities

==

at

==

the

==

NRC.

==

The

==

staff

==

pointed

==

out

==

that

==

there

==

was

==

a

==

high

==

level

==

of

==

interest

==

in

==

the

==

RITSTF

==

activities

==

and

==

that

==

we

==

needed

==

to

==

understand

==

how

==

broad

==

the

==

interest

==

in

==

the

==

industry

==

was.

==

The

==

staff

==

presented

==

several

==

thoughts

==

on

==

a

==

long-term

==

vision

==

for

==

risk-

==

informed

==

TS

==

and

==

acknowledged

==

that

==

structure

==

and

==

resource

==

issues

==

will

==

need

==

to

==

be

==

worked

==

out.

==

The

==

staff

==

also

==

pointed

==

out

==

that

==

it

==

will

==

need

==

to

==

address

==

the

==

four

==

strategic

==

performance

==

goals

==

identified

==

in

==

the

==

Commissions

==

Nuclear

==

Reactor

==

Safety

==

Strategic

==

Plan.

==

Those

==

performance

==

goals

==

are:

==

(1)

==

Maintain

==

safety;

==

(2)

==

Increase

==

public

==

confidence;

==

(3)

==

Reduce

==

unnecessary

==

regulatory

==

burden;

==

and

==

(4)

==

Make

==

NRC

==

activities

==

and

==

decisions

==

more

==

effective,

==

efficient,

==

and

==

realistic.

==

The

==

RITSTF

==

presented

==

some

==

of

==

its

==

thoughts

==

on

==

a

==

long-term

==

vision

==

for

==

risk-informed

==

TS.

==

Much

==

of

==

the

==

discussion

==

focused

==

on

==

a

==

slide

==

which

==

presented

==

the

==

Westinghouse

==

Owners

==

Group

==

(WOG)

==

five

==

year

==

risk-informed

==

TS

==

strategy.

==

The

==

group

==

discussed

==

at

==

what

==

point

==

rulemaking

==

might

==

be

==

needed

==

to

==

accommodate

==

all

==

of

==

the

==

envisioned

==

changes

==

to

==

TS.

==

The

==

group

==

also

==

discussed

==

the

==

issue

==

of

==

PRA

==

quality

==

and

==

the

==

fact

==

that

==

the

==

ASME

==

PRA

==

standard

==

currently

==

being

==

developed

==

did

==

not

==

address

==

configuration

==

risk

==

management

==

tools

==

like

==

those

==

envisioned

==

as

==

necessary

==

to

==

implement

==

many

==

of

==

the

==

TS

==

changes

==

under

==

development.

==

Representatives

==

from

==

the

==

South

==

Texas

==

Project

==

presented

==

a

==

concept

==

of

==

a

==

fully

==

risk-informed

==

set

==

of

==

TS

==

that

==

essentially

==

relies

==

on

==

a

==

CRMP

==

as

==

the

==

backbone

==

of

==

the

==

TS.

==

They

==

likened

==

the

==

proposed

==

risk

==

limits

==

in

==

their

==

concept

==

to

==

radiation

==

protection

==

limits

==

(i.e.,

==

ALARA

==

limits).

==

The

==

NRC

==

regulates

==

ALARA

==

limits

==

at

==

a

==

high

==

level

==

and

==

licensees

==

control

==

these

==

limits

==

at

==

a

==

lower

==

level

==

administratively.

==

The

==

group

==

also

==

discussed

==

whether

==

there

==

was

==

a

==

need

==

for

==

an

==

instantaneous

==

risk

==

cap

==

for

==

TS.

==

The

==

RITSTF

==

stated

==

that

==

the

==

major

==

question

==

is

==

the

==

cost

==

benefit

==

of

==

going

==

to

==

this

==

extreme.

==

For

==

example,

==

if

==

plant

==

PRAs

==

essentially

==

become

==

the

==

TS,

==

then

==

licensees

==

would

==

have

==

to

==

control

==

changes

==

to

==

the

==

PRA

==

model

==

to

==

the

==

same

==

degree

==

as

==

TS

==

changes

==

are

==

currently

==

controlled.

==

The

==

RITSTF

==

presented

==

a

==

status

==

of

==

the

==

seven

==

initiatives

==

currently

==

under

==

development.

==

The

==

group

==

discussed

==

Initiative

==

  1. 1

==

related

==

to

==

safe

==

end

==

states.

==

The

==

RITSTF

==

stated

==

that

==

the

==

expected

==

results

==

were

==

confirmed

==

by

==

the

==

PRA

==

work

==

done

==

by

==

SONGS.

==

The

==

group

==

again

==

discussed

==

what

==

work

==

the

==

other

==

owners

==

groups

==

planned

==

to

==

do

==

to

==

justify

==

the

==

changes

==

for

==

their

==

plant

==

types

==

by

==

taking

==

3

==

Enclosure

==

==

advantage

==

of

==

the

==

SONGS

==

and

==

CEOG

==

work.

==

Updated

==

schedules

==

for

==

the

==

various

==

initiatives

==

were

==

discussed.

==

The

==

RITSTF

==

stated

==

that

==

they

==

expected

==

to

==

submit

==

Initiative

==

  1. 1

==

in

==

February

==

or

==

March

==

2000.

==

Initiatives

==

  1. 2

==

and

==

  1. 3

==

were

==

expected

==

to

==

be

==

submitted

==

in

==

the

==

very

==

near

==

future.

==

Initiative

==

  1. 4

==

was

==

planned

for

submittal

==

in

late

==

2000.

==

Initiatives

==

5,

6,

==

and

==

7

==

were

==

also

==

expected

==

in

mid

==

to

late

==

2000.

==

The

group

==

briefly

==

discussed

the

planned

process

for

reviewing

these

as

to

the

The
