Appendix—Electrical Testing

In recent years test methods have been largely standardised by the International 

Electrotechnical Commission (lEC) in close collaboration with the International

Some brief notes on the testing of electrical properties are given in the appendix at the end of this chapter.

As indicated in Chapter 2 (Section 2.2B), the terms in the chemical potential can be justified or derived by various methods. The forms of some terms in i can be readily appreciated because they follow from familiar definitions of work, such as the electrical term and the gravitational term. Hie comparison with Fick s first law indicates that RT In a, is the appropriate form for the activity term. Another derivation of the / Tln a, term is in Appendix IV, together with a discussion of the pressure term for both liquids and gases. Some of these derivations incorporate conclusions from empirical observations. Moreover, the fact that the chemical potential can be expressed as a series of terms that can be added together agrees with experiment. Thus a thermodynamic expression for the chemical potential such as Equation 2.4 does the folio whig (1) summarizes the results of previous observations, (2) withstands the test of experiments, and (3) leads to new and useful predictions. 

The loop test results should be recorded (a sample instrument loop check sheet has been provided for reference purposes in Appendix 23D) and included with the site test records. Checks for mechanical/electrical completeness are recorded using the upper section of the sheet and the dytramic loop test results are recorded on the lower section. The test results sheets will provide the documentary evidence essential for Installation Qualification (IQ). Representatives from the installation contractor and/or the customer will witness the final loop tests and countersign the test sheets. Any tests not witnessed must be accompanied by written confirmation from the customer that witnessing has been waived. 

The barbiturates are substituted pyrimidine derivatives with an ureide configuration (Fig. 20.4). They are lipophilic weak acids (pKa 7-8) that are weii distributed into brain (see Appendix A for the respective pKa values). Although many barbiturates dispiay sedative-hypnotic activity (see Chapter 19), oniy a few have antiseizure properties. Paradoxically, many barbiturates cause convulsions at larger doses. The barbiturates clinically useful as AEDs are phenobarbital, mephobarbital, and primidone (Fig. 20.8). In laboratory animals, phenobarbital is effective by several tests in nontoxic doses. It is active against electrically induced seizures (MES), and it elevates the threshold for pentylenetetrazole stimulation. The mechanism of antiseizure action for the barbiturates... 

Materials used in floor coverings and textiles, seat cushions, trays and galleys, and electrical and ducting equipment must meet the 12-second test [14CFR 25.853(a) Appendix F Part I (a) (I) (ii)]. In order to pass this test, the average burn length of the materials may not exceed 8 in. the average flame time after removal from the flame source may not exceed 15 seconds. 

The certificate should he based upon the model form set out in Appendix 6 of the lEE Regulations. It should include the test values which verify that the installation complies with the regulations for electrical installations at... 

This appendix provides a brief description of the Fast Flux Test Facility (FFTF) fuel handling system and its operation as described by Cabell (1980) and in the Fast Flux Test Facility System Design Description (FFTF, 1983). The description is limited to those system features that are potentially relevant to the refueling of a liquid-salt very high-temperature reactor (LS-VHTR). Because the FFTF was designed as a reactor to test fuel, it has additional capabilities and equipment compared with a sodium-cooled fast reactor designed only to produce electricity. 

Much information is available on ageing problems of NPPs. Extensive programmes are being conducted in the IAEA and in its Member States. The objectives of many of the studies are metal ageing (mostly steels) and degradation of concrete structures, electrical equipment, electronic components, elastomers and lubricants. Most of this research has been carried out in research reactors, some of them almost exclusively dedicated to material testing (see Appendix IV). 

The National Electrical Manufacmrers Association (NEMA) has organized and maintained standards on the manufacture, testing, and performance of laminated thermosetting products in the form of sheets, rods and tubes. NEMA material descriptions and the properties of NEMA-type laminates are provided in Appendix E. 

Dynamic and seismic qualification testing and analysis of the electrical equipment listed in CESSAR-DC Appendix 3.11B are addressed in CESSAR-DC Section 3.10 except for pump motors and valve motor operators, which are addressed in CESSAR-DC Section 3.9.2.2. The tests and analyses are performed in accordance with IEEE Std 344-1987 (Reference 9), which is endorsed by Regulatory Guide 1.100. 

The NRG therefore evaluated the power systems of operating plants to determine the susceptibility of safety-related electrical equipment to (1) a sustained undervoltage condition on the offsite power source (2) a rapid rate of decay of the offsite power source frequency and (3) interaction of the offsite and onsite power sources. An additional factor evaluated was (4) the adequacy of testing requirements. New criteria relative to factors (1), (3) and (4) above were issued in Branch Technical Position (BTP) PSB-1 "Adequacy of Station Electric Distribution System Voltages", which was incorporated in SRP Section 8.3.1, Appendix A (Reference 2). Frequency decay [factor (2)] was found not to be a significant safety issue.
