APPENDIX A 

PROCEDURE CONTENT 

Administrative Procedures: procedures that provide a clear understanding of operating 

philosophy and management policies to ensure safe operation of the plant within the 

limits set by the operating license and Technical Specifications. They ensure that plant 

activities are conducted in a manner that will protect the general public, plant personnel, 

and equipment. 

Administrative procedures should also include, as a minimum, a definition of proper shift 

turnover and a description of what is required for the proper transfer of responsibilities 

when a reactor or a senior reactor operator on duty is relieved of control room 

responsibilities during a shift or during shift change. 

General Plant Operating Procedures: procedures used to guide operations after reactor 

startup. General operating procedures include reactivity control procedures. 

Startup Procedures: procedures that direct reactor operation from shutdown conditions, 

through startup, and up to power with the generator synchronized. Startup procedures 

may also have special provisions for scram recoveries. The review should focus on 

whether the procedure adequately specifies plant conditions and prerequisites for 

startup and the limits in effect during the startup. 

Shutdown Procedures: procedures that guide system operations during and following a 

controlled shutdown. They prescribe the subsequent actions of operators after a scram 

has occurred, if the reactor is not to be returned to power immediately. Conditions for 

these operations may be controlled by a mode switch. 

Note: Shutdown operations, as well as startup operations, may be guided by a 

controlling procedure which refers to other procedures for equipment operation or 

these operations may be an integral part of the procedures. 

System Operating Procedures: procedures that provide detailed steps to ensure safe 

operation of the systems which support and control reactor operation. 

Surveillance Test Procedures: procedures written for each surveillance test listed in the 

licensee’s technical specifications. The procedures are provided to ensure that tools, 

gauges, instruments, controls, and other measuring and testing devices are properly 

controlled, calibrated, and adjusted at specified periods to maintain accuracy in 

performing surveillance for safety related equipment. 

Abnormal Operating Procedures (alarm response procedures): procedures that specify 

actions to restore an operating variable to its normal controlled value when it goes out of 

normal bounds, or to restore normal operating conditions following a perturbation. If the 

condition is not corrected, it could degenerate into a condition requiring action under an 

emergency procedure. 
Issue Date: 08/19/08XX A-2 42453 

Emergency Operating Procedures: procedures which specify operator actions to 

reduce the consequences of an accident or a hazardous condition which has already 

occurred or developed. If the condition is not corrected, or prepared for, a threat to the 

public health and safety may occur, and portions or all of the emergency plan may have 

to be invoked. 

Standing orders: orders used to disseminate to the plant staff instructions of a general 

and continuing nature. They may deal with such items as job turnover and relief, 

definition of the duties of operators, transmittal of operating data to management, filing 

of charts, etc. 

Special orders or night orders: orders used to disseminate management instructions 

that have short-term applicability. They deal with such items as special operations, 

housekeeping, data taking, plotting process parameters, personnel actions, etc. 

Emergency Plan: procedures used to implement the site emergency plan. Emergency 

Plan implementing procedures ensure timely and accurate emergency classification, 

onsite and offsite notification and reporting of emergency events, and identification and 

recommendation of onsite and offsite protective actions. 

Refueling Procedures: procedures used during refueling operations. Refueling 

procedures include fuel receipt and inspection; preparations for refueling including 

vessel head stud detensioning, vessel head removal, removal of steam dryers and 

moisture separators, reactor vessel cavity seal installation, and flooding of reactor 

cavity; refueling bridge operation to include Local Power Range Monitor (LPRM) 

removal and replacement; fuel movement from a flooded reactor cavity to a spent fuel 

storage pool; control rod unlatching, removal, and installation; and reactor vessel 

reassembly, including replacement of reactor vessel O-Rings. 

Technical support procedures: procedures that relate to activities such as the conduct of 

preventive and corrective maintenance, measuring and test equipment, radiation 

protection, and chemistry control.

APPENDIX B 

PROCEDURE USABILITY 

Incorporating human factors principles into procedures increases the likelihood that the 

procedures will be easier to use and follow. Standards for format and writing style will 

usually be found in the licensee's writer's guide. Usability should be determined by 

evaluating the degree to which procedures follow the guidance outlined in the writer's 

guide. 

When a writer's guide is not available or if the writer's guide is in question, procedure 

usability can be determined by evaluating the elements of writing style and format and 

organization. The list that follows each element below describes characteristics that 

increase the likelihood that a procedure will be performed successfully. 

WRITING STYLE The information in a procedure is presented in a manner that 

increases the likelihood that the task will be performed successfully. 

Procedures are more likely to be performed successfully if: 

● The writing style is consistent among procedures within a department and within 

the same procedure type. 

● The level of detail is appropriate for the complexity of the task and the expected 

ability of the users. 

● Descriptions of actions to be taken are easy to understand and unambiguous. 

- Action instructions are written as separate and positive commands. 

- Short, simple sentences are used. 

- Multiple actions are written in order of sequence and clearly identify when 

actions must be completed in order of occurrence. 

- Acronyms and other abbreviations are used consistently and are defined 

explicitly. 

- Quantitative words are used in instructions. 

● References to equipment or documents contain complete identification 

information, including plant unit applicability, and exactly match equipment 

labels. 

● Numerical units used in procedures correspond to the units on the related 

instrumentation. 

● Conditional statements are presented using the appropriate format. 

- IF and WHEN are used to present a condition. 

- THEN is used to present an action. 

- IF NOT is used in combination with THEN to present an alternative. 

- NOT is used to emphasize an opposite condition (NOT running). 

- AND is used to present all conditions that must be met before taking 

action. 
Issue Date: 08/19/08 B-2 42453 

- OR is used to present one or more conditions that must be met before 

taking action. 

FORMAT AND ORGANIZATION An uncluttered appearance and clear structure of the 

information in a procedure increase the likelihood that the task will be performed 

successfully. 

Procedures are more likely to be performed successfully if: 

● Organization is hierarchical, logical, consistent, and reveals the organization to 

users through the use of headings. 

● Step numbering and structure is not overly complex. 

● Appendices and attachments provide explicit guidance for their allowed use and 

present relevant information that would be difficult to integrate into the 

procedure. 

● Figures and charts are explicitly and uniquely identified so they are easy to find 

within the procedure. 

● Procedure identification information is adequate to ensure the procedure is 

complete and current. 

● Procedure is legible in the worst expected conditions for use. Type is readable 

(1) at an expected distance within which the procedure is used, (2) after copying 

and (3) under degraded lighting. 

● Job aids are used to help users to track their progress through a procedure 

where applicable. 

● Warnings, cautions and notes (WCNs) are consistent within a department and 

within a procedure type. 

- WCNs are obvious and address a single topic. 

- WCNs are linked to the related procedure step. 

- WCNs contain no actions. 

- Warnings and cautions identify the consequence of wrong action. 

- Notes supply only supplemental information. 

● The final step is clearly indicated. 

● Checklist information reflects the sequence of information in the steps of the 

procedure.

that the conditional statement precedes the action statement? 

 
Issue Date: 08/19/08 B-7 42453 

 Attribute Yes No N/A 

34 Are contingency instructions easy to understand? For example, if 

three or more conditions are associated with an action, they 

should be listed separately from and ahead of the action 

statement. 

 

35 Are the titles and numbers of all referenced documents identified 

correctly and consistently? 

 

36 Does the procedure contain provisions for coordinating the 

activities of others? For example, is there a checklist for a
