SUMMARY
AND RECOMMENRTIONS he Prairie Island ERP conceptual design package lacked the necessary information to evaluate the adequacy of the emergency response facilities. The following areas had little or no information available for review:
The design package did not address the functions of the TSC.
Although the licensee provided a diagran of the room layout in the 'ISC, there was insufficient information on the computer display and comunication facilities located at each work station.
Concerning TSC habitability, the licensee states the TSC i
meets the guidance of NUREG-0696, but no information was provided for evaluation.
More detailed information is required on radiation i
monitoring systens in the TSC and supplies of protective clothing, respiratory equignent and potassium iodide.
1 The licensee did not provide information to evaluate whether the TSC would be fully functional within 30 minutes of activation.
The subject of backup comunication in the 'ISC was not addressed. More information is required concerning TSC i
communication.
Although most of the required records for the TSC are available in the office area adjacent to the TSC, there is no information on the procedures for updating the records to i
ensure they are current and complete.
i The design package did not address the control room.
i The functions of the OSC were not sufficiently addressed.
The design package contained insufficient detail concerning l
OSC habitability.
The licensee does not intend to provide a direct and dedicated primary communication link between the OSC and the control room and the OSC and the TSC. The design package states comunication is by two extensions for the planc phone system.
L Page 1-1 e
Prairie Island The size of the OSC was not addressed.
l Se licensee did not address the functions of the BOF.
W e licensee provided insufficient information to evaluate the location, structure and habitability of the EDF.
t The design package provided an extensive description of the functions of the EDF staff but no information on the time required for the EDF to become fmetional.
The only information provided on the size of the EDF was a diagram wnich outlined rooms and functions to be supprted in the rooms. Further information is required on equipnent to be utilized to support the functions, and space for storage of records.
Se licensee states that radiological monitoring and alarming will be provided at the EDF but provides no details.
Insufficient information is provided on EDF communications and records availability and management.
Priaire Island is planning a phased approach to the data acquisition system to be used to support the ERF's. The first phase involves an upgrading of their interim data acquisition and display system. During Phase II they plan to install a computer based dose assessment system that will include on-line availacility of meteorological data and radiation release data.
In the final phase (Phase III) the plant process computer will be replaced and a plant multiplexing system and computer driven control room enhancement system will be installed. The licensee is a member of a group of utilities who are jointly funding the development of a generic safety parameter display software system (SAS) wnich will be impleented on the data acquisition and display computer to be installed in Phase III.
Se interim technical data system comprises three systems: a process caputer acquisition and display system which displays all data points accessed by the plant processors; the Transienc
!!cnitoring System ('IMS) which consists of a data acquisition system and recorder that captures initial plant data and a subsystem that provides instantaneous real time plant information at the TSC; and an offsite dose calculation system for projecting offsite dose rates at various distances. The licensee did not provide enough detail information in the areas of data acquisition display, comtmications or system support to perform an evaluation of the interim system.
Se licensee is completing detailed specifications for the Page 1-2
Prairie Island computer systems to be installed in Phase II and Phase III.
Therefore, an evaluation of the proposed systems is impossible at this time.
'Ihe utility proposes to implenent a Safety Assessment System (SAS) which they claim "provides a centralized,
- flexible, computer-based data and display system to assist control room personnel in evaluating the safety status of the plant." SAS displays are also provided to the ERF's, and the claim is made that the SAS meets the requirements of NUREG-0696 with respect to the SPDS. Graphical displays, including a pri:rary display of a minimum set of key plant parameters, are presented on a high-resolution multiplcM:olor CRr. The forrat for this display employs bar graphs, digital indicators, and digital values.
Several secondary displays may abe selected by means of function keys.
Data displayed by the SAS is validated by comparing redundant sensors and performing several types of reasonableness checks, apparently in software. Persons with plant operating exnerience, including control room operators, have been directly involved in the design of the SAS display formats.
The validation and verification program for SAS software includes static tests for each software module, as well as dynamic tests generated by recording nuclear plant simulator data en :ragnetic tape. Verification of future software modifications will be handled by freeing a selected set of static test cases during implementation.
The information provided indicates that the Safety Assessment System is a well-designed data acquisition and display system which is capable of meeting or exceeding the requirements of NUREG-0696 relating to acquisition and display of technical data with respect to the SPDS. However, the licensee proposes to implement the system on the data acquisition and display computer to be installed in Phase III. Because no details were provided on that computer it is impossible to evaluate its adequacy for this system. In addition, further details must be provided on the display forrats and contents for the SAS.

- 1. The design of the Technical Support Center (TSC) addresses the following goals:
- a. Provides plant management and technical support to plant operations personm1 during emergency conditions;
- b. Relieves the reactor operators of peripheral duties and cor=unications not directly related to reactor system ranipulatiens;
- c. Prevents congestion in the control room; and
- d. Performs EOF functions for the Alert Ebergency class and for the Site Area Emergency class and General Emergency class until the EDF is functional.
- 2. The TSC shall be the emergency operaticns work area for designated technical, engineering, and senior licensee plant ranagement personnel; any other licensee-designated personnel required to provide the needed technical start; and a srall staff of NRC personnel.
- 3. S e TSC shall have facilities to styrt the plant management and technical personnel who will be assigned there during an energency and will be the prirary onsite ccmmunications center for the plant during the emergency. TSC personnel shall use the TSC data system to analyze the plant steady-state and dyramic behavior prior to and throughout the course of an accident. The results of this analysis will be used to provide guidance to tne control room operating personnel in the management of abnormal conditiens and in accident mitigation. TSC personnel will also use the environmental and Page 2-1
