1 INTRODUC' DON
' Itis report suminarizes Westinghouse's evaluation of potential turbine missiles above the turbine deck from the high pressure (HP) rotor and the low pressure (LP) rotor discs of '.he HP 294 and LP 281 turbine elements for Unit 1, North Anna Station, Vi:ginia Electric & Power Company, Serial Numbers 13 A3591-1, 23A3592-1, and 23A3593-1. The contents of this report supersede any previously issued information for this unit on turbine missile energies.

2 DESCRIPTION OF TURBINE ELEMENTS 2.1 High Pressure Turbine
.
The HP element is a double flow design similar to the HP double flow design shown in Figure 1, and consists of a forged single-piece double flow rotor, a cast steel outer cylinder, and four cast steel blade rings supported inside the outer cylinder. Steam from four control valves enters nozzle chambers at the center of i
the turbine element through four inlet pipes (two in the cylinder base and two in the cylinder cover). In these chambers, the steam is distributed equally to both halves of the rotor and flows axially through the blading to the exhaust chambers f at each end of the HP cylinder. The HP cylinder cover and base are held together
&
at the horizontal joint by studs and stud-bolts have lengths ranging from 23 to 59 20043 1

inches and diameters ranging from 2.50 to 3.50 inches. The total cross-sectional area of the studs and bolts L approximately 620 square inches and the total free- !
length volume is approximately 31,500 cubic inches.
2.2 Low Pressure Turbine The LP turbines are of a double flow design similar to the double flow design shown in Figure 2. Each element consists of a double flow rotor assembly, an outer cylinder, two inner cylinders, and blade rings. The rotor assembly consists of a shaft with 10 shrunk-on discs made of low alloy steel and two shrunk-on couplings. Steam enters at the top of each oster cylinder where it flows to the inlet chamber of the inner cylinders. In the L.kt chamber, the steam is distri-buted equally to both halves of the rotor and flows through the blading to the
'
condenser. LP turbines are numbered from the HP element to the generator. The LP-1 element is next to the HP element, the highest numbered LP element is next to the generator.

3.1.2 In predicting the ability of the fragment to penetrate the turbine casing, test 1 i
results and analytical considerations indicate that the~translational kinetic energy l
Of a fragment is of much greater importance than the rotational kinetic energy. !
Rotational kinetic energy tends to be dissipated as a result of friction forces !
developed between the surface of the disc or rotor fragment and the stationary part; therefore, rotational kinetic energy was not considered in the penetration calculations.
3.1.3 The analysis considers the energy absorbed by the inner and outer cylinders, blade rings, and cylinder rings where appropriate. The results of R&D tests, including the 1979 non-symmetrical tests, are incorporated into the analysis.
.
3.1.4 When missile energies exiting the turbine are less than 100,000 ft-lb, they are not reported in the Analysis Results section of this report.
3.1.5 Blade ring and cylinder exiting fragments vary significantly in shape. Fragments of equivalent area are reported rather than furnishing separate tables and sketches for the numerous possible configurations (refer to Figure 3). HP/LP turbine cylinder and blade ring fragment equivedent areas are tabulated in TABLES I and 2.
. .
3.1.6 Minimum ultimate strength was used to establish the dynamic strength of the cylinders and blade rings for the missil.e penetration calculations.

3.2 High Pressure Turbine
.
3.2.1 For this report, it is assumed that the HP rotor falls as shown in Figrare 4. Failure such as that illustrated will generate eight fragments that may become missiles; note that the two end sections of the rotor are assumed not to become missiles.
HP turbine missile impact areas and dimensions are given in Figure 5 and tabula- I
. ted in TABLE 3.
3.2.2 It is not necessary to calculate missiles at the ductile bursting speed of the HP rotor since this burrting speed is higher than the theoretical terminal speed of the -
unit. ,
3.2.3 The ejection angle of the HP rotor fragments is assumed to be + 5 degrees mea-
_
sured from the vertical radial plane perpendicular to the rotor's longitudinal axis.
3.3 Low Pressure Turbine 3.3.1 In evaluating the capability of LP turbine structures to contain fragments, it is assumed that a single disc falls and fractures into several parts. Segments of 90, 120 and 180 degrees have been considered but only 90 and 120 degree segment
~
~
properties are reported. Because of kinematic considerations, a 180 degree disc 1
segment will have a lower initial translational energy and more of the energy is absorbed by the internal structures. As a result, the likelihood of generating 2C043 8 CT24821/0

l missiles is less than for the other segments, and exit energies will be lower. LP turbine missile impact areas and dimensions are given in Figure 6 and tabulated in TABLES 4 and 5.
1he potential for distributed bore cracks and field experience indicate that an LP l
disc burst may result in major segments (hub to rim fractures) varying in size from l approximately 30 to 200 degrees. Although missile data for only 90 and 120 l l
- degree segments are presented in this report, an assessment was made to l determine if smaller, larger, or intermediate size disc segments could exit with higher energies. The results of this assessment indicate that 90 and 120 degree segments are reasonable approximations for the highest exiting energy disc segment. '
.
,
3.3.2 The bursting speed of each shrunk-on disc is calculated. The criterion used is that the disc will fail when the average tangential stress equals the maximum temperature corrected tensile strength of the disc material. The maximum value was taken as the minimum specification value plus 20 KSI. Upon failure of the initial disc, further acceleration is assumed to halt because of damage to the turbine. For purposes of calculating and reporting the energies of missiles, all other discs are assumed to fail at the same speed as the initial disc.
3.3.3 The calculated value of destructive overspeed for this unit is 191% of rated
.
. .
speed. This is the speed at which the initial LP dise fails. The No. 2 disc is the initial disc to fall on this unit.

o Disc 5: 5 degrees to 25 degrees measured from the vertical radial plane passing through the disc. Fragments from this dise will eject only towards the cylinder end wall.
