Printed in the United States of America Foreword (This Foreword is not a part of American National Standard for Lubricating Oil Systems for Safety-Related Emergency D
15、iesel Generators, ANSI/ANS-59.52-1998.) This standard is applicable to light water reactor nuclear power plants and is one of a series of standards, sponsored by the LWR Criteria Management Subcommittee (MC-I ), intended to cover the design of auxiliary systems that support the operation of emergenc
16、y diesel generator units. Other standards in this series that have been or are being developed by this working group are listed below: Proposed Standard ANS-59.51 ANS-59.53 ANS-59.54 ANS-59.55 Subject Fuel Oil Systems Starting Air Systems Combustion Air Systems Coolant Systems This standard interfac
17、es with American National Standard Criteria for Diesel-Generator Units Applied as Standby Power Supplies for Nuclear Power Generating Stations, ANSI/IEEE 387-1995. That standard does not address fluid system or component performance or design criteria. To address these fluid system requirements, thi
18、s standard includes in its scope the pumps, tanks, piping and piping components, and instrumentation and control functions, as described herein. Based on discussions with the working group chairman for ANSI/IEEE 387, it was agreed that the intent of that standard is to address only the overall quali
19、fications and boundaries of the diesel generator auxiliary systems and not the specific performance or design criteria, which are addressed in ANS-59.52. The purpose of this standard, and the related standards under development, is to provide guidance to nuclear plant owners, designers, manufacturer
20、s, regulatory authorities, and operators, in the design of reliable, safety-related, onsite power systems for light water reactors. The reliability of lubricating oil systems must be considered when satisfying the overall reliability requirements of the diesel generator units. This is particularly i
21、mportant iflubricating oil systems have components that are shared between reactor units, and if the single failure criterion is applied. This standard can also be used for non-safety-related onsite power systems, with several changes to eliminate those requirements which would not normally apply to
22、 such equipment. For example, non-safety-related equipment would not normally have to meet American National Standard Single Failure Criteria for Light Water Reactor Safety-Related Fluid Systems, ANSI/ANS-58.9-198I (RI987), the Class IE Power Systems requirements of American National Standard Criter
23、ia for Class IE Power Systems for Nuclear Power Generating Stations, ANSI/IEEE 308-1992, and several of the requirements described in American National Standard Nuclear Safety Criteria for Design of Stationary Pressurized Water Reactor Plants, ANSIIANS-5I.1-I983 (RI988) and American National Standar
24、d Nuclear Safety Criteria for Design of Stationary Boiling Water Reactor Plants, ANSIIANS-52.I-I983 (RI988), for safety-related equipment, such as Seismic Category I. Other requirements, such as American National Standard ASME Boiler and Pressure Vessel Code-I995, Section XI, “Rules for Inservice In
25、spection of Nuclear Power Plant Components,“ and American National Standard Quality Assurance Program Requirements for Nuclear Facilities,ANSI/ASME NQA-1-I994, which normally apply to safety-related equipment but which are considered to enhance reliability, could be optional or modified to suit a pa

An area that contains nuclear safety related equipment. 3. System Function The lubricating oil system shall be designed to deliver an adequate supply of filt
31、ered oil within an appropriate temperature range to the EDGs under all plant conditions that are defined in American National Standard Nuclear Safety Criteria for the Design of Stationary Pressur ized Water Reactor Plants,ANSI/ANS-51.1-1983 (R1988) 6, and American National Standard Nuclear Safety Cr
32、iteria for the Design of Sta tionary Boiling Water Reactor Plants, ANSI/ANS-52.1-1983 (R1988) 7. During standby, the lubricating oil system shall be designed to circulate lubricating oil to the EDG engine to enhance starting capability and to en sure conditions under which the engine-driven oil pump
33、 can pressurize the system quickly following engine starts. 2 4. System Description The lubricating oil system consists of independ ent subsystems each dedicated to supplying lu bricating oil to a single EDG unit. Each sub system consists of sumps or sump tanks, pumps, filters, strainers, valves, pi
34、ping, piping compo nents, instruments, and controls.2 This standard has been prepared with the as sumption that active components are used to transfer the lubricating oil from a storage tank to the sump or sump tanks of an EDG. A gravity drain system is an acceptable alternative; how ever, if the la
35、tter is used, consideration shall be given to potential system leakage and its con sequences. 5. System Performance Require ments 5.1 General. The lubricating oil system, exclud ing the keep-warm and reserve portions, shall be designed to remain operable during and after all design basis events. The
36、 keep-warm and reserve portions of the system shall be designed to maintain pressure boundary integrity during all design basis events. The lubricating oil sub system for each EDG shall be completely inde pendent of other EDGs so that a single failure will not result in the loss of required minimum
37、EDG capacity. This requirement shall apply re gardless of the number of reactors at a site. The onsite lubricating oil storage capacity for each EDG shall be sufficient to operate the EDG for seven days following any design basis event. During this period it shall be assumed that no off-site ac powe
38、r is available. Storage capacity shall be calculated in accordance with 5.2 of this standard. 5.2 Calculation of Lubricating Oil Storage Capacity Requirements. The lubricating oil system minimum storage capacity requirement for each EDG shall be calculated conservatively through determination of the
39、 minimum quantity of lubricating oil required to support continuous engine operation, at the licensed engine rating, for seven days. If a reserve lubricating oil stor age tank is used to meet the seven-day lubri cating oil capacity requirement, only the useable 2 Refer to Appendix A and Figure 1 for

The minimum capacity shall be calculated as follows: C = L + (Lr)(7 days)(1440 minlday)(l.lO) where: C = EDG lubricating oil storage capacity Oiter or gal). L = require
42、d capacity of lubricating oil to fill completely the EDG lubricating oil subsystem to the manufacturers recommended minimum level. Lr = lubricating oil consumption rate associated with continuous operation at the licensed engine rating (liter/min or gal/min). 5.3 Component Performance Requirements 5
43、.3.1 Sumps and, If Applicable, Reserve Lubricating Oil Storage Tanks. Each EDG shall have a storage capacity to maintain at least seven days of operation, without dropping below the manufacturers recommended minimum lu bricating oil inventory. The capacity calculation shall assume lubricating oil co
44、nsumption with the diesel engine running at its continuous duty engine rating. The minimum total storage capa city on site shall be equal to the number of re quired EDGs times the lubricating oil capacity as calculated in 5.2 of this standard. If the required quantity of lubricating oil cannot be co
45、ntained in the EDG sump or sump tank, the additional lubricating oil needed for the seven day supply shall be stored in a reserve lubricating oil storage tank. Additional lubricating oil capa city beyond the minimum seven day requirement can be stored in the EDG sump, an EDG lubri cating oil day tan
46、k, a separate common portable lubricating oil tank, or drums. If a reserve lubricating oil storage tank is pro vided to meet the seven-day requirement, the design shall include provision for the automatic American National Standard ANSI/ANS-59.521998 transfer of lubricating oil from the reserve lu b
47、ricating oil storage tank to the sump. The re serve lubricating oil storage tank, if applicable, shall be of seismic design, independent, and per manently connected to the EDG. The reserve lu bricating oil storage tank shall also be designed with provisions for level indication, water remov al, and
48、sampling of the lubricating oil. Methods to prevent overfilling of the sump during lubri cating oil transfer shall be provided. The design of the EDG sump, sump tank, and (if applicable) reserve tank shall include provisions for the addition of lubricating oil during EDG operation. The lubricating o
49、il subsystem shall be designed to prevent any residual sediment or accumulated water from entering the sumps or sump tanks. 5.3.2 Pumps. A keep-warm oil pump shall be provided to maintain engine lubricating oil pas sages in a warmed and filled state when the EDG is in the standby mode. The keep-warm oil pump may be used as a pre lube pump, provided the pressure and flow re quirements of the two functions are compatible. A reserve lubricating oil transfer pump shall be provided to deliver lubricating oil from the re serve lubricating oil storage tank to the EDG sumps or sump tan
