1. BACKGROUND

The 327 Building, Post-Irradiation Testing Laboratory, is a Category 2-nonreactor nuclear facility currently operated by B&W Hanford Company (BWHC) for Fluor Daniel Hanford, Inc (FDH). Operating since 1953, the 327 Building was designed to provide shielded, ventilated, and specially equipped laboratories for physical and metallurgical examination and testing of irradiated fuels, concentrated fission products, and structural materials in support of operational efforts being carried out at Hanford. The primary operating area on the main floor includes a canyon area and connecting bays where auxiliary operations are performed. The canyon area contains shielded cells and the cell operating stations and consoles. A transfer and storage area is located at one end of the building. Two bridge cranes are used to transfer casks containing radioactive structural materials or fuel from the receiving area to the cells or between the cells.

2. PURPOSE

The purpose of this document is to document the hazard baseline for the 327 Building. The hazard baseline was developed using two techniques; walking down the facility and completing checklists and preparing a Preliminary Hazards Analysis (PHA).

This hazard baseline document identifies the hazards in the 327 Building at the time of the facility walk through, presents a PHA of stabilization and deactivation activities, and provides a basis for the hazard evaluation and accident analysis that will be developed in the 327 Building Basis for Interim Operation (BIO).

3. SCOPE

Activities addressed in this hazard baseline document include:

Stabilization and deactivation activities in preparation for eventual decommissioning of the 327 Building and the routine handling, processing, and shipment of waste to support these activities.

324/327 Building Minimum Safe Project engineering and maintenance activities to maintain ' the building and systems viable--especially the Safety SSCs-to allow stabilization, deactivation, and waste handling activities with a minimum risk to workers, the public, and the environment.

'

Stabilization and deactivation activities will remove and/or reduce human health and environmental hazards associated with the 327 Building, and will place the facility in the lowest radiological classification possible. These activities concentrate on removing, reducing, and

1

HNF-4607

Revision 0

stabilizing the industrial, radiological, and chemical hazards remaining in the building at the time of transition from its operational mission. Following stabilization and deactivation, the 327 Building will be placed in surveillance and maintenance mode pending re-use or final Decontamination and Decommissioning (D&D) when the facility is turned over to the Environmental Restoration and Management Contractor.

4. HAZARD IDENTIFICATION

Safety Analysis consists of a hazards analysis and an accident analysis. Safety analysis requirements for existing Hanford site facilities are established by HNF-PRO-430, Safety Analysis Program; HNF-PRO-700, Safety Analysis and Technical Safety Requirements; and HNF-PRO-701, Safety Analysis Process - Existing Facility. In accordance with these requirements, guidance for the preparation of this safety analysis was taken fiom DOE-STD-3011-94, Guidance for Preparation ofDOE 5480.22 (TSR) and DOE 5480.23 (SAR) Implementution Plans and from HNF-PRO-704, Hazard and Accident Analysis Process. DOE-STD-3011-94 and HNF-PRO-704 both specify the application of the graded approach to the safety analysis effort. The safety analysis must be comprehensive enough to demonstrate the following:

the facility hazards are understood and all of the major hazards have been evaluated, and dominant accident scenarios with the potential for significant consequences inside or outside the facility have been identified, and features (both engineered and administrative) are established to prevent or mitigate the consequences of the identified accidents.

The hazards analysis is required to: be based on the inventory enveloping radioactive and hazardous materials that may be stored, used, or formed within the 327 Building; and identify the energy sources that may contribute to an uncontrolled release of radioactive or other hazardous material.

The potential hazards associated with the 327 Building were identified by:

reviewing historical safety documentation; reviewing facility operating procedures; reviewing the proposed stabilization and deactivation activities; discussions with building personnel and subject matter experts; and performing and documenting a physical walkthrough of the building.

The existing safety documentation reviewed included the following:

Revision 0

The 327 Building is a Hazard Category 2 facility and has transitioned from process operations to stabilization and deactivation activities. Based on this information, the use of hazard checklists and a preliminary hazards analysis (PHA) technique to evaluate the major hazards are appropriate to systematically identify the hazards baseline for the 327 Building.

Table 1 provides an overview of the stabilizatioddeactivation activities addressed during the hazard identification process.

HNF-SD-HT-FHA-003,327 Facility Fire Hazard Analysis (Hughes 1997).

Table 1. Stabilization and Deactivation Activities Evaluated

4.1 HAZARD CHECKLISTS

A walkthrough of the facility was conducted to ensure that the significant quantities of radioactive or hazardous materials and energy sources associated with the facility design, processes, and stabilizatioddeactivation activities were identified. A Hazardous MaterialEnergy Source Checklist ("F-PRO-704, Table 2) was used to document observations for specific locations within the building during the walkthrough.

The checklist provides a list of hazard categories (e.g., electrical, flammable materials, and ionizing radiation sources) to assist in the identification process, each of which contains several specific sub-elements. Hazards on the checklists existing within the individual location were noted on the checklists, including the quantity, chemical and physical form (as applicable), and process or storage condition. In addition, the existence of any additional hazards not appearing on the checklists was noted. Discussions with building personnel and subject matter experts were held during the walkthrough and also subsequent to its completion in order to confirm locations and quantities of hazards.

Hazards were then evaluated to identify the potential scenarios that could lead to significant releases of radioactive or hazardous materials and to rank these scenarios based on potential consequences and frequency. Based on the rankings, bounding accidents for each type of postulated scenario will be further developed in the 327 Building BIO.

Completed checklists are provided in Appendix A.

4.2 PRELIMINARY HAZARD ANALYSIS

A PHA technique was used to systematically review and document the hazards associated with stabilization and deactivation activities. The PHA form was used for the analysis of the hazards associated with the 327 Building. A brief description of the content of each column on the PHA form follows.

EquipmentlArea - lists the specific type(s) of equipment involved in the postulated accident and/or the area of the facility involved.

Activity - provides a brief description of the action taking place when the postulated accident might occur.

Hazard - lists the intrinsic hazard (radioactivity, toxic material, etc.) present or potentially present in the process or facility being analyzed.

Accident - refers to an abnormal event or sequence of events that, combined with the intrinsic hazard could potentially result in adverse consequences to a facility worker and/or person at a distance from the facility.

Cause - list an abnormal event or combination of event that might initiate the accident.

Consequence - describes the postulated unmitigated consequences of the accident.

Consequence Rank - contains a rating of the accident consequence severity. Unmitigated consequences of accidents resolving airborne releases of radioactive material were ranked. Because the low hazardous chemical inventories, the airborne release consequences of hazardous chemical were ranked low. Accidents involving exposures to facility workers were ranked using engineering judgement. Accidents involving worker injury due to standard industrial hazards were ranked IND.

Frequency Rank - contains an estimate of the accident frequency. Abbreviations used are A for anticipated (frequency greater than lO-'/yr); U for unlikely (frequency between lO-'/yr and 104/yr); and EU for extremely unlikely (frequency less than 106/yr).

Engineered Control - lists the engineered design features that might act to mitigate or prevent the consequences of the hazardous conditions.

Administrative Control - lists the administrative controls (e.g., procedure) that might act to mitigate or prevent the consequences of the hazardous conditions.

Comments - notes special conditions that might apply to the postulated accident or items for hrther resolution as deactivation planning progresses.

Completed PHA forms for each activity identified in Table 1 are provided in Appendix B.
