1. 0 INTRODUCTION


1.1 The Pressurizer Safety Valve (PSV), made and supplied by the

Industrial Valve Operations o.f Dresser Industries, Incorpora-

ted, for use in Pressurized Water Reactors (PWR), is sold

under the trademark "Consolidated Closed Bonnet Maxiflow

Safety Valve" (Model 31700). These valves are designed and

certified under Section III of the ASME B&PV Code for applica-

tion in Nuclear .Power Systems.

The PSV is a spring loaded safety valve with a bellows and is

actuated by a rise of internal steam pressure in excess of a

specified value. The principles of design are the same for

all PSV's in service or intended for service in domestic PWR's.

For participating utilities, Dresser has supplied PSV's for

twenty-nine (29) nuclear PWR plants. A total of ninety-four

(94) valves, including spares, have been supplied for these

plants. Table 2 lists PSV's by utilitY, plant, valve model

number, size and description.

The basic valve model number is 31700. For those valves

listed in Table 2, the model number has the form 317X9YA-Z,

where X, Y and Z are variables. The variables X and Y in-

dicate the valve orifice size. Valve orifice sizes are

identified either by a number or a letter. Table 1 lists the

SV-178 Rev. l Page 4 of 29

different orifices and their designations. If the orifice

size designation is a number, then X is that number and Y

has no value. If the orifice size designat')on is a letter,

then X is zero and Y is that letter. The dash variable z is

a design interchangeability number. There are two interchange-

ability numbers: -1 and -2.

Within any one valve model, the variable features are:

(1) Inlet size, pressure rating, and facing;

(2) Outlet size, pressure rating, and facing;

Variable features are listed in the description column of

Table 2.

2.0 DESCRIPTION OF THE BASIC V~.LVE MODEL

2ol Operation


Valve operation is similar for all 31700 model valves. A

cross-section of a basic valve model is shown in Figure 1.

The valve consists of a nozzle that is internally contained

by an external body structure and a disc that.is held

against the nozz·le seat by a mechanical force that is develop-

ed by compressing a helical spring. The valve opens on an

inlet overpressure transient that generates sufficient up~

ward force against the disc to overcome the resisting spring

force. The valve closes when the overpressure decays to a

point where the spring force is able to reseat the disc.

Review Figures l, 2, 3 and 4.

As shown in Section A-A of Figure 3, the valve seat is the

nozzle/disc interface. The valve is held in the closed position

by the spring force acting through the spindle to the disc a~

shown in Figure 2o This force maintains the nozzle/disc in~

terface thus trapping inlet steam within the inner chamber

of the nozzle and disc.

When the inlet steam pressure (P 9 ) reaches a predetermined

point (set pressure), a vertical force is generated that

counterbalances the spring force and slight leakage of steam

•

•

SV-178 Rev. l' Page 17 of 29

across the valve seat develops. This leakage is directed

into the huddle chamber (Figure 3). Pressure builds up

rapidly in the huddle chamber developing an addition vertical

force on the disc and disc holder. This additional force in

conjunction with the expansive characteristics of steam causes

the valve to "pop" open to al:1!1ost full lift. Simultaneously,

the steam is directed through the secondary orifice and the

adjusting ring flow gap. Steam momentum and the exposure of

the entire area of the disc holder to steam pressure causes

the valve to continue into full lift allowing the lift stop

to come in contact with the support plate. Also, steam bleeds

through the clearance at the lower guide/disc holder inter-

face generating an addition lifting force on the upper portion

of the disc holder.

When the valve is open and flowing, static and dynamic forces

act as shown in Figure 4.

Force F1. This vertical upward force exists due to steam

flow against the disc.

Force F2. This vertical upward force exists due to dif-

ferent pressure forces acting on an annular area defined

by the inside diameter of the disc seat and by the lower

outside diameter of the disc holder. The Force F2 is

controlled by the position of the lower and middle adiusting

rings.


Force F3· This vertical downward force exists due to

spring force which is defined by set pressure times seat

area plus an additional force of valve lift times spring

rate.

Force F4. This vertical downward force exists due to

steam bleeding through the clearances between various

parts (the guide/disc holder interfaces: the disc/disc

holder interface: the bellows disc nut/disc holder thread

interface). Force F4 is also influenced by the body bowl

pressure near the upper and lower port holes in the

guide.

Force Fs. This vertical upward force exists due to steam bleeding through the lower guide/disc holder interface

and expending into the chamber under the upper portion

of the disc holder. Steam flow out of this chamber is

affected by the position of the upper adjusting, by body

bowl pressure near the lower port holes in the guide, and

by the upper guide/disc holder interface.

When the overpressure condition is relieved,.the inlet pressure

in the nozzle decreases (F1, F2, Fs) allowing the spring force

(F3) plus the pressure builtup at the top of the disc holder

(F4) to reseat the disc thereby closing the valve.

•

•

•


Adjusting rings are mechanical devices incorporated in the

valve to change the distribution of forces on the disc and

disc holder affect valve opening pressure, valve lift, and

valve closing pressure.

2.2 Opening Pressure

Opening pressure (also called set pressure or popping pressure)

is that pressure where the valve disc begins to lift due to

an inlet overpressure transient. Lift begins when inlet steam

pressure has increased to the point where the force generated

is equal to spring load. The spring load is adjusted by

turning the compression screw (Figure 1, Ref. No. 9). In

accordance with the ASME Section III Code, the valve opening

pressure can be adjusted to be within plus or minus one percent

of the required opening pressure.

Opening pressure is affected by seat leakage, by the position

of the lower ring, and.ambie~t temperatures. Excessive seat

leakage caus~ng a· steam pressure build-up in the huddle chamber

may cause erratic set pressure or a premature "pop". The

huddle chamber and the secondary orifice size are defined by

position of the lower adjusting ring. The lower adjusting

ring eliminates simmer just prior to the valve popping to

insure a sharp and distinct popping pressure. Ambient tempera-

tures affect the valve normal temperature profile. Large

ambient temperature transients may cause the valve to open

outside the normal plus or minus one percent set pressure tel-

erance because rraterial relaxation or growth affect spring force.


The bellows is designed to provide the maximum huddle chamber

efficiency. Reduced huddle chamber efficiency occurs only at

high back pressure conditions. This could cause· the opera-

tion of the valve to become sluggish if the bellows was not

designed to allow the valve to be fully open at 3% accumulation.

Due to its design, a bellows is a highly stressed component,

and can be damaged if subjected. to very extreme adverse con-

ditions or severe cycling. Since the bellows performs such a

.necessary function in the valve and is not readily accessible

for inspection, a backup system is provided. This is shown

in Figure 4 as the back pressure balancing piston. In case of

a bellows rupture, the area internal to the bellows will be~

come pressurized, however, the piston li.ft stop being attached

to the valve spindle (which carries spring force) is now subject

to high pressure on its bottom side and approximately atmos-

pheric pressure on its top side. This unbalance force assists

the valve to open or remain open thereby accomplishing the

same function as the bellows except for leak tightn~~s be~ween

the outlet and bo~net. Flow will vent into the valve bonnet . .

through the clearance between the piston and floating washer

and this will be vented out of the valve bonnet. It is necessary

that the valve bonnet vent connection always be left open to

atmospheric pressure because the lift stop is designed to

act as a piston with the floating washer as a cylinder. Since

the effective area of the bellows and the lift stop are designed

to be equal, a ruptured bellows will have little affect on

_valve operation IF THE BONNET IS PROPERLY VENTED.

•

•

•

•

2.3 Closing Pressure


Closing pressure is that pressure at which the valve will

reseat. ·This is generally specified as percent blowdown and

is expressed by the following equation.

Percent Blowdown =

popping pressure minus

closing pressure

popping pressure x 100

When the overpressure condition is relieved, the inlet pressure

in the nozzle decreases allowing the spring force plus the

pressure buildup at the top of the disc holder to force the

disc back on its seat, thereby closing the valve as shown in

Figure 3.

The force F4 acts as a closing force because back pressure

cannot be eliminated. For low back pressure applications, F4

can usually be ignored. At high back pressures, the effect

of F4 is significant since it would affect valve lift and

capacity. In order to provide total system relieving capa-

bility under high back pressure conditions, the 31700 Safety

Valve is designed with a patented back pressure compensator

piston (part of disc holder) , which utilizes and controls

Force F5 . Force F5 acts on the piston in the annular area

outside of the guide diameter. This flow is regulated by the

compensator flow ports. The upper adjusting ring is set at the


factory to insure valve lift and capacity even with high back

pressures expected in serviceo

2.4 Capacity

Orifice size, valve lift, and inlet pressure affects valve

capacity. The basic valve model is certified in accordance with

the AS.ME Section III Code to relieveo A rated capacity at a

three percent overpressure at rated lift at a steady state con-

ditiono

Valve capacity is calculated in according with AS.ME Section III

Code with the formula

W = 5lo5A(l.03P + 14.i) (.975) (0.9)

W = saturated steam, lb/hr A = orifice area, sqo in. P = set pressure, psig

Lift is the actual travel of the disc upward along the valve

centerline when the valve is relieving.

Rated lift is that minimum lift at which a valve attains its

rated capacity at a three percent (3%) overpressure (accumula-

tion) . By design, the rated· lift for the basic valve model

is the lift that provides a certain area (Figure 4) equal to

the area of orifice bore (Table 1) . Rated lift is calculated

by dividing the orifice bore by four.

•

•

•

•


The basic valve model has an adjustable lift stop as shown in

Figures 3 and 4. The valve lift can be restricted below rated

lift to restrict valve capacity. The relationship between

valve lift and capacity is conservatively assumed to be

linear.

2.5 Material of Construction

Figure 1 Nomenclature provides typical Material of Construction

for the basic valve model. ~1a terial of Construction for all

PSV's are the same (i.e., same material grade). However, the

material specifications, to which materials were procured,

varies (i.e. AISI versus ASTM versus ASME). Also material

form varies (i.e. castings versus forging versus bar stock) .

2.6 Design Conditions

The basic valve model has a design pressure of 2500 psig and

a design temperature of 7QQOF. The valve is designed specifi-

cally for saturated steam service. The valve is not designed

for, nor tested by Dresser on any other flow media.

3.0 SELECTED TEST VALVES


3.1 Two valve sizes are selected for the EPRI Test Program. These

are:

(1) Model: 31739A-l

tJtility: Consumer Power Company

Plant: Midland 2

Drawing: 3NC-081 (Note 1)

(2) Model: 3l709NA-l

Utility: Portland General Electric

Plant: Pebble Springs l

Drawing: 3NC-045 (Note 2)

Note 1. The original drawing for Midland 2 is not readable

when reduced to a 11" x 17" format. For that reason,

Drawing 3NC-081 has been used in this report. Drawing 3NC-081 is for the Crystal River spare valve. The Midland valve and

the Crystal River spare valve are identical.

Note 2. The original drawing for the Pebble Springs is not

readable when reduced to an 11" x 17" format. For that reason,

Drawing 3NC-045 is provided in this report. Drawing 3NC~045

is for the Palo Verde valves. The Palo Verde valves are

identical to the Pebble Spring valve except that:

(1) The inlet face is a large tongue, and

(2) The body drain is a socket weld connection.

( 3) 31759A, 5 or if ice

( 4) 31749A, 4 orifice

( 5) 31709NA, N or if ice

4.2 Comparison of Valve Models

•

Each larger size valve is a scaled-up version of the smaller

valves. All valves are similar in configuration and based on

the same design philosophy.

Within each valve model, there are some critical variations.

These are:

l. Bonnet Material Form

2. Body (Base) Material Form

3. Inlet Size and Rating

4. Outlet Size and Rating

5. Lift

4.3 Bonnet Material Form

Bonnet were originally manufactured from a casting. Cast

bonnets were replaced with a bonnet fabricated from a solid

forged billet. The casting were ASTM A217 Grade WCB. The

forgings were ASTM Al05 Grade II Carbon Steel or ASME SA105

Carbon Steel depending on the applicable ASME Section III Code .

The two bonnets, cast or forged type, are very similar in con-

figuration and considered structurally equivalent.


The original valves (Model 31739A-l) for Palisades, Oconee l

and 2, and Three Mile Island 1 Nuclear Plants have bonnets of

the cast type. Spare valves for TMI #1 have bonnets of the

forged type. All other valves have bonnets of the forged

type.

4.4 Body Material Form

Bodies were originally manufactured from a casting. Material

was ASTM A35l Grade 316 stainless steel. Later in valves of

the same model number, a body made from a solid forged billet

was used. Material was ASTM -~~~1~ ~rade F3l6 or ASME SA182

Grade F3l6 stainless steel. More recent valves, models

31749A~2 and 31709NA-l, have bodies made from a closed die

forging. Material was ASME SA182 Grade F316 stainless steel.

The original valves for

(l) Calvert Cliffs 1 (Model 31739A-l)

( 2) Palisades (Model 317 39A-l)

(.3) Oconee 1 & 2 (Model 317 39A-l)

( 4) Main Yankee (Model 31709KA=l)

( 5) Three Mile Island 1 (Model 31739A-l) and

( 6) North Anna 1 & 2 (Model 31759A-l).

Have valves of the cast type. The two original valves for

Calvert Cliff 2 (Model 31739A-ll were cast and forged types

(one of each) . Spare valves for Calvert Cliffs l and 2 and

Three Mile Island 1 have bodies of the forged type. All other

valves have bodies of the forged type.

•

•

•

SV-178

Rev. 1 Page 27 of 29

The bodies of the cast type and the forge type are similar

in configuration. However, the body bowl wall thickness

of the cast type is thinner than the wall of the forged type.

Thus the cast type is structurally weaker.

5.0 CONCLUSION


Although there is a possible argument for selectinq for the

tests valves which have been installed and in use for a number

of years as opposed to newly manufactured valves, it would be

difficult to achieve this in practice. There is first the

problem of obtaining valves for prolonged testing which are

at present used by utilities. There are also the handling and

control difficulties which will be presented by a valve which

is highly radioactive. Any attempt to decontaminate the

valve would tend to nullify the tests. In fact, it is believed

that there is no real need to become involved in such a poten-

tially troublesome test program. The affect of radiation

aging of the materials used in valve construction is well

known and has been defined by many reliable authorities which

it is unnecessary to quote here. The total radiation dosage

is comparatively small and those operating components which

may be the most affected are replaced under normal maintenance

procedures at regular intervals-. . -This, also applies in the

c~se of we.ar or. f·atigue: There is very little wear experi-

enced in the valve in general because of the limited number

of operating cvcles and certainly, in the case of PWR's there

is no possibility of fatigue failure from vibration.

The 3l739A-1 and the 31709NA-l valves selected for the EPRI

testing program are representative of valves in service or

intended for service in the PWR plants listed in Table 2.

SV-178 Rev. 1 Page 29of 29

The first of these valves, the 3 orifice is the most common

and has the longest service history. The N orifice is the

newest and largest and is expected to be the valve used in

new plants. Unfortunately, the two variations of the 3 size,

cast or forged body, may present a problem. For normal opera-

tion on saturated steam the valves are the same, but it is

possible that under extreme conditions of compressed flashing

water there may be some difference because of body configuration.
