26A6380 SH NO. 4 GE Nuclear Energy REV2 1.0 TEST OBJECTIVE The objective of the steam dryer hammer test is to identify the as-built frequencies and mode shapes of several key components of the Quad Cities-2 steam dryer at ambient environment conditions. Different components of the steam dryer have different frequencies and mode shapes associated with them. The areas of interest are the drain channel, the outer hood panel, the inner hood panel, the side panel, the tie bar and the skirt.

The concern is that local natural frequencies may coincide with existing forcing functions to cause resonance conditions. The resonance could cause high stresses to occur in localized areas of the steam dryer. A Finite Element Modal Analysis can calculate the frequency and mode shape of a component, but they are only approximations to the real values due to variations in plate thickness, welding, and other assumptions regarding boundary conditions.

The mode shapes and frequencies determined by the hammer test will be used to validate the finite element modal analysis.

2.0 TEST DESCRIPTION 2.1 Test Description The hammer test will be performed at a remote facility after the installation of the sensors for in-reactor vibration measurement is completed. Two types of impact tests will be performed on the dryer: a (1) dry hammer test, and a (2) wet hammer test with the steam dryer skirt and drain channel partially submerged in different water levels. Temporary accelerometers will be installed at predetermined locations for this test. Some of the sensors and instrumented hammers that may be submerged during this test shall be waterproofed.

An instrumented hammer will be used to excite the steam dryer. The dryer components will be impacted with the hammer at several pre-determined locations and data will be recorded in the DAS.

After completion of the hammer test, a static load test shall be performed on the front hood on the 270 deg side. Temporary strain gages shall be installed to measure the strain levels when the load is applied. This information shall be used to verify the dryer model.

2.2 Data Acquisition System (DAS)

The DAS shall have the capability of acquiring data from all sensors on a particular component under test simultaneously for online analysis or storing data for offline analysis.

26A6380 SH NO. 5 GE Nuclear Energy REV2 The digital storage system shall be controlled by one PC and shall record signals from all channels simultaneously. The storage system shall comprise of modules converting analog voltage signals into digital signals. Data shall be converted and archived in a non-proprietary format. The system shall have the appropriate transfer rate to support direct data transfer without the need of a data buffer.

The data acquisition and analysis system shall be capable of performing transfer function measurements and spectral analysis. It also shall have the capability of displaying signal time histories for selected channels. The system shall have a minimum frequency bandwidth capability from 0 to 400Hz.

The data analyzer shall be capable of real time spectrum analysis with a minimum of 400 line resolution and at least 60 dB dynamic range. Outputs must be available for hard copy printout.

The tape recorder, if used, shall record all channels simultaneously or in groups. It shall be calibrated and be used as backup storage to the primary PC storage system. The tape recorder shall have a minimum frequency bandwidth range of DC to 400Hz. The input voltage range shall be +/-0.5V to a minimum of IOV programmable. It shall support voice recording for identification.

2.3 Communication Link A voice communication link between the impact hammer test personnel and the DAS engineer will be required to perform the test if the DAS location is not within audible distance from the dryer.

3.0 SIl rE INSTALLATION 3.1 Equipment Installation The DAS test equipment area should be set up as close as possible near the steam dryer test area to minimize the' cable length. The DAS will require a 11OV, 60HZ, 30amp power source to power the test instruments.

3.2 Sensor Installation Temporary accelerometers and strain gages will be installed on the dryer for the hammer test. Location of the accelerometers will be determined based on finite element analysis of the steam dryer.

Sensor cables will be clearly labeled at each end, and connected to the corresponding sensor signal conditioning unit located in the DAS area. Continuity checks will be performed on all signal cables to verify proper sensor connections to the DAS. The DAS will obtain data from all sensors and the instrumented hammer simultaneously.

Inhalation: YES Skin: YES Ingestion: Accidental Health Hazards (Acute and Chronic): Bonds skin rapidly and strongly.

Carcinogenicity: NTP: Not listed IARC Monographs: Not listed OSHA Regulated: Not listed Signs and Symptoms of Exposure:

INHALATION: Vapor is irritating to nose and bronchial passages. Prolonged and repeated over-exposure to vapors may produce allergic reactions with asthma-like symptoms insensitive individuals.

EYE CONTACT: Cyanoacrylates may bond eyelid to eyelid and/or eye.

SKIN CONTACT: Cyanoacrylates bond skin rapidly and strongly. Alarge drop may cause bum upon solidificabon.

INGESTION: It is almost impossible to swallow cyanoacrylates. The adhesive solidifies and adheres inmouth.

Lips may become stuck together.

Conditions Generally Aggravated by Exposure: None known.

SECTION 4: EMERGENCY AND FIRST AID PROCEDURES Information for first aid and casualty on treatment for adhesion of human skin to itself if caused by cyanoacrylate adhesives.

Cyanoacrylate adhesive isavery fast setting and strong adhesive. Itbonds human tissue including skin in seconds. Experience has shown that accidents due to cyanoacrylates are handled best by passive, non-surgical first aid. Treatment of specific types of accidents are given below.

SKIN CONTACT: Remove excess adhesive. Soak inwarm, soapy water. The adhesive will come loose from the skin inseveral hours. Dried adhesive does not present a health hazard even when bonded to the skin. Avoid contact with clothes, fabric, rags or tissue. Contact with these materials may cause polymerization. The polymerization of large amounts of adhesive will generate heat causing smoke, skin bums, and strong, irritabng vapors. Wear rubber or polyethylene gloves and an apron when handling large amounts of adhesive.

SKIN ADHESION: First, immerse the bonded surface inwarm soapy water. Peel or roll the surfaces apart with the aid of ablunt edge, e.g. aspatula or a teaspoon handle; then remove adhesive from the skin with soap and water.

Do not try to pull surfaces apart with a direct opposing action.

2 805-FRM011

M-Bond 200 Adhesive MSDS # MGM0070 EYELID TO EYELID OR EYEBALL ADHESION: Inthe event that eyelids are stuck together or bonded to the eyeball, wash thoroughly with warm water and apply a gauze patch. The eye will open without further action, typically in 1- 4 days. There will be no residual damage. Do not try to open the eyes by manipulation.

ADHESIVE ON THE EYEBALL: Cyanoacrylate introduced into the eyes will attach itself to the eye protein and will disassociate from it over an indeterminable period, generally covering several hours. This will cause periods of weeping until clearance is achieved. During the period of contamination, double vision may be experienced together with a lachrymatory effect, and it is important to understand the cause and realize that disassociation will normally occur within a matter of hours, even with gross contamination.

MOUTH: If lips are accidentally stuck together, apply lots of warm water to the lips and encourage maximum wetting and pressure from saliva inside the mouth. Peel or roll lips apart. Do not try to pull the lips with direct opposing action.

It isalmost impossible to swallow cyanoacrylate. The adhesive solidifies and adheres in the mouth. Saliva will lift the adhesive in 1/2 to 2 days. Incase a lump forms inthe mouth, position the patient to prevent ingestion of the lump when it detaches.

INGESTION: Saliva should lift the adhesive in 12 to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Do not force removal. Do not swallow the adhesive when it loosens.

BURNS: Cyanoacrylates give off heat on solidification. Inrare cases a large drop will increase in temperature enough to cause a bum.

Bums should be treated normally after the lump of cyanoacrylate is released from the tissue as described above.

SURGERY: It should never be necessary to use such a drastic method to separate accidentally bonded skin.

INHALATION: Move to fresh air. If symptoms persist; call a physician.
