B/B-UFSAR 13.5-1 REVISION 5 - DECEMBER 1994 13.5 PLANT PROCEDURES Day-to-day operations of the B yron/Braidwood Stations are governed by procedure manuals within ass igned areas of responsibility. The se manuals govern em ployee actions and establish standards for plant operation.
A formalized sys tem of written procedu res containing administrative and operating instructions in conformance with Regulatory Guide 1.33 and AN SI N18.7-1976/AN S-3.2, which acknowledges the safety provisions of the facility license and Technical Specifications, is e mployed to ensure that all normal and reasonably foreseeab le abnormal or emerg ency activities are conducted in a safe manner.
Detailed station procedures (i.e., p lant procedures) are prepared by members of the station st aff or by persons under their direction.
13.5.1 Administ rative Procedures
13.5.1.1 Quality Assurance Re quirements for Operation
The Byron/Braidwood plant proced ures are written to conform to applicable quality assurance requireme nts for operation.
13.5.1.2 Preparation of Initial Procedures
The Byron/Braidwood admi nistrative procedures are prepared by members of the stati on organization or p ersons under their direction. The responsibility for writing and preparing plant procedures is assigned to the appropriate depa rtment heads of the station organization.
Procedures and n ecessary changes are rev iewed and approved in accordance with station procedures.
13.5.1.3 Procedures
The Byron/Braidwood Administrati ve Procedures identify station organization and responsibilitie s, control r oom procedures, operating criteria, requiremen ts for records , a summary of required tests, analyses, and calibrations to be performed, their frequency of performance, and the group respon sible for this work. 13.5.1.3.1 Standing Operating Orders
Special Operating Orders are i ssued to provide a mechanism for dissemination of instructions and information of continuing importance to shift oper ations. Special Opera ting Orders may be long term, if desired, and are not to be sub stituted for either permanent or tem porary procedures.
B/B-UFSAR 13.5-2 REVISION 8 - DECEMBER 2000 13.5.1.3.2 Daily Operating Orders Daily Operating Orders a re issued to pro vide a mechanism for dissemination of management inst ructions which h ave short-term applicability. Dail y Operating Orders are not to be a substitute for either permanent or temporary procedures.
13.5.1.3.3 Equipment Control Procedures
Equipment control procedures a re established to provide for the necessary control of equipment to maintain plant equipment and personnel safety and to avoid unauthorized o peration of equipment. These inst ructions utilize the control measure of tagging to secure an d identify equipment in a controlled status.
The use of equipment l ocks is employed in ce rtain circumstances in conjunction with the tagging procedure or in the absence of the tagging procedure to ensure that the safety of plant equipment and personnel is not jeopardized.
Verification and control procedures a re utilized when e quipment locking is
necessary.
13.5.1.3.4 Control of Mai ntenance and Modification Control of maintenance and modification is provided for in Reference 1.
13.5.1.3.5 Master Surveil lance Testing Schedule A master surveillance testing schedule is prepared which prescribes the s urveillance to be perfor med and the frequency as outlined in the Technical Spec ifications and the Technical Requirements Manual.

Logbooks are maintained in the control area, radwaste control room, and Shift Manager's office.
Entry items in these books include unit plant equipment status, mal function, reactor trips (including the r easons), changes in oper ating conditions, test and measurements performed, and other significant information
noted by the operating crew or the Shift Man ager. The Shift Manager normally signs t he Shift Manager's l og to acknowledge understanding of its contents re specting plant s tatus. Prior to shift changeovers, the oncoming Shift Manager must r ead the log of the off-going Shift Manager to ensure com plete understanding of the plant conditi ons before assuming shift responsibilities.
13.5.1.3.7 Temporary Procedures
Temporary procedures may be issu ed to direct s pecific operator actions during operations testing and mainte nance, to provide
B/B-UFSAR 13.5-3 guidance in unusual situations n ot within th e scope of the station operating proc edures, and to ens ure orderly and uniform operations for s hort periods when the plant, a system, or a component of a system is performing in a manner such that portions of existing pro cedures do n ot apply.
Temporary procedures require r eview and approval according to the station review pro cess and must be a uthorized by the appropriate management representatives prior to implementation.
