- 5. DETAILS OF TEST PROCEDURE 1hc test cycle will consist of:
- 1) Normal Service Qualification
- 2) D.B.E. Qualification
- 3) Post Event Qualification This series of orents is meant to duplicate the conditions of a typical fan / motor unit during its lifc in a nuclear
_ statien, normal service until the LOCA, function through the LOCA, service after the LOCA. * ( The first step in the procedure will be nomal service qualification, which itself is divided into: A) Thermal _ Endurance Testing ' B) Seismic Qualification
.; Thermal Endurance The thermal endurance, comonly called heat aging, is in accordance with IEEE 334 dated 1-30-74.
Af ter a full series of motor tests to establish a bench mark for the entire test, the themal endurance consists of: Place motor in cold oven. Expo ,e to " aging temperature" for specified qualification time. Relubricate as required to duplicate nomal servicing. The aging temperature i s defined as per IlilI331 in etinjunction with IEEE117. In summary:
- a. Identify an implied average life characteristic for the insulation system of the motor which was obtained
,' by the IEEE117 motorette test procedure. "When the logarithms of the hours of life found by themal evaluation tests of three (3) or more different tempern-tures are plotted on a graph against the reciproenis of the absolute temperature, they will usually, but not always, form a straight line." "
- b. Identify the expected average operating temperature of the motor by conducting a heat run on the motor.

myg .fune 2.s, as*
- c. Plot this temperature and the desired life timo at a point on the graph. The expected design life, under normal ambient conditions, was set at 40 years.
- d. Draw a line through this point, parallc1 to the implied average life characteristics. Identify the line as the
, implied average aging characteristic. The inter-section of this line with the desired aging time gives the aging temperature.
Application of thi's technique to qualify an insulation system at 65c C. rise and 500 C. ambient temperature for '40 years ( design life requires acceleration to 2270 C. for 100 hours. Scismic Qualification The scismic qualification is intended tn.cstablish the adequacy of the fan / motor system to perform following a D.lhE.; procedures will follow IEEE 344 dated 6-25-73.
' A one (1) degree of freedom, static analysis, will be performed on the fan / motor system to establish the allowable loading permissibic, assuming a 1/.67 horizontal / vertical acceleration ratio, and allowabic stress at 90% of yield strength.
A series of vibration tests will be conducted to experimentally define any resonant conditions of the fan / motor combination and also to demonstrate the ability of the combination to withstand
, vibration.

" fragility test" per IEEE 344. Given the natural frequencies of fan / motor combination and a scismic loading level .of about 2 g's
- minimum, the endurance demonstration can begin.
Testing will be independently conducted on the radial and axial axis, with the fan idle and running at free discharge. Test frequencies will be any resonance found in operating i . range. Test duration will be twenty (20) seconds minimum , per IEEE 344, 1971. Per the current IEEE 344, cach test combination will be exposed to ten (10) half scismic loadings and one (1) full seismic loading. ( ' IEEE 429 recommends ih g loading, but customers specify up to 1.8 g. If no resonance is detected in the operating range, scismic durability will be demonstrated by exposing the fan / motor combination to one (1) hour of 60 liertz cxcitation.1 The lubricant-bearing-seal system will experience the same aging cycle as the other components and will be considered pre-conditioned by this experience. No radiation exposure will be attempted for the lubrication or other system due to the safety limitations. Flotorette radiation tests were conducted to verify this parameter. At the conclusion of the vibration testing, the fan / motor combination will have been pre-conditioned to the extent
.\ expected during normal service life prior to the D.B.E.
Although IEEE 334 specifically requires pre-conditioning as part' of the D.B.E. qualification tests, the nomal service qualification supersedes such a necd, consequently, the qualification proc,cdure is reduced to that of only the actual D.B.li. environmental simulat ion. i Eum,B i I s

1 The purpose of this report is to sunmari e the results of testing undertaken to qualify a JOY AXIVANE fan driven by j
; a Reliance Electric motor for service in containment for ;
j both BWR and PWR units per IEEE 334-1974. The test procedure was defined in FF-14282 and this proecdure i was followed as closely as possible. I e l Basically this test program included: }' I I 1. Motor llent Aging - to accelerate motor life 1 I j to 40 years. i .. j 2. Fan Resonant Search - to define any resonant ,
- areas. I n
- 3. Vibration Endurance Testing l ,
i' .
- 4. T o (2) LOCA Simulations - to show the fan capability of the fan to eperate over an O .
extended period after a 1,0CA condition.

Description:
) The fa.i selected for use on this test was a 60 inch diameter fan. The casing used for the vibration testing portion of the f program was a typical production casing for nuclear service.
l The fan was driven by a 150/75 IIP Reliance Electric motor.
- This was a 1200/600 RPM motor in a 11-5008 frame. The motor 4 insulation was Class 11, Type RN, which is designed for the l*
- following . conditions:
9 1 ..
- 1. Radiation - maximum dosar.c of I x 10' rads of gamma g
g radiation during the life of the motor. . l 2. Short time temperature during emergency mode of 350 0 F. ambient (for 3 to 4 hours), then gradual { reduction to 2500 F. l
- 3. Ambicnt pressure of 85 psig during emergency mode. ,
I 4 One (1) year exposure to 100% relative humidity
; with vapor droplets and slightly caustic stuosphere.

MW PHILADELPhlA, OHIO A E P0" NC -W NtiPARED i>Y I. A. Pitsett catcxco G r J.T. ZeiRict 3Ari February 17, 1978 h r m w POST-TEST EXAMINATION After termination of the test, the pressure chamber was opened to allow visual examination of the motor. There was some corrosion on the motor frame which was concentrated in an area where chemical spray impinged directly on the motor. This was a function of the test arrangement. There was also some buildup scale on the back side of the rear support plate for the motor. Neither of the above had progressed to the point where they would be considered detri-mental. The inside of the test chamber was relatively clean with little corrosion present. See photos on Pages 13 and 14 of Appendix B. The motor was then removed and sent back to the vendor for teardow and a complete post-test inspection. The subsequent inspection
.r,evealed the following: .
- 1) .The rotor had a light surface corrosion but was in relatively good shape. ., ,
- 2) The motor fan key had worked. loos'c but the fan was still operational. This was a random type problem not associated
, ' with the qualificatiorr test. ..
- 3) The bearings rotated freely and appeared in good condition.
- 4) The stator winding was covered with a dry black powdery residue and had failed in the coil head opposite the connection end at the 8:00 o' clock position. The most probable cause of this failure was excessive voltage surge across the winding following one of the many un-
{j scheduled power interruptions. 1
- 5) The insulation was very hard and brittle but intact; a I
' condition considered normal for a motor aged in excess of 40 year life. - 9 i t f ummuun W e 1 j i
